neural network architecture, addressing the limitations of existing methods that rely on pre-aligned scans. By ensuring that the model is agnostic to pose and scale, the authors demonstrate that architectural equivariance is crucial for achieving robust generalization in real-world applications. The proposed network outperforms both equivariant and augmentation-based baselines on the PCN benchmark, achieving a 17% reduction in minimal matching distance on KITTI and a 14% decrease in Chamfer distance on OmniObject3D, setting new cross-domain records.\n", + "\n", + "The methodology integrates modular layers that canonicalize features, reason over similarity-invariant geometry, and restore the original frame, effectively disentangling intrinsic geometry from extrinsic transforms. This architectural innovation not only enhances performance but also establishes a rigorous evaluation protocol that eliminates hidden biases, reinforcing the significance of SIM(3) equivariance for reliable shape completion in practical scenarios. The implications for industries such as robotics, autonomous driving, and cultural heritage digitization are substantial, as the model facilitates accurate shape reconstruction from incomplete data.

By ensuring that the model is agnostic to pose and scale, the authors demonstrate that architectural equivariance is crucial for achieving robust generalization in real-world applications. The proposed network outperforms both equivariant and augmentation-based baselines on the PCN benchmark, achieving a 17% reduction in minimal matching distance on KITTI and a 14% decrease in Chamfer distance on OmniObject3D, setting new cross-domain records.\n", "\n", "The methodology integrates modular layers that canonicalize features, reason over similarity-invariant geometry, and restore the original frame, effectively disentangling intrinsic geometry from extrinsic transforms. This architectural innovation not only enhances performance but also establishes a rigorous evaluation protocol that eliminates hidden biases, reinforcing the significance of SIM(3) equivariance for reliable shape completion in practical scenarios. The implications for industries such as robotics, autonomous driving, and cultural heritage digitization are substantial, as the model facilitates accurate shape reconstruction from incomplete data.

Similarly, maintaining sanitation can prevent pests from finding food and shelter, thereby reducing their ability to survive and reproduce.\\n\\nThese cultural controls are often considered preventive measures, as they can help prevent pest problems from occurring in the first place.

Similarly, maintaining sanitation can prevent pests from finding food and shelter, thereby reducing their ability to survive and reproduce.\\n\\nThese cultural controls are often considered preventive measures, as they can help prevent pest problems from occurring in the first place.

However, in the presence of noise, these eigenvectors may still exhibit non-zero gradients in directions orthogonal to the manifold, causing them to acquire components in the noise directions [27, 28, 29, 30, 31] and consequently distorting the tangent space estimates.\\n\\nFortunately, a principle analogous to classical Fourier analysis applies: just as the low-frequency Fourier modes capture the underlying signal while high-frequency modes tend to encode noise [32, 33, 34], it is commonly observed that the eigenvectors corresponding to small eigenvalues of the graph Laplacian are robust to noise while the ones lying deeper into the spectrum may have nontrivial gradient in the noise directions [27, 28, 29, 30, 31], as demonstrated in Figure 1c. Building upon this insight, in this work, we propose an algorithm that estimates the tangent spaces at data points using the gradients of low- frequency global eigenvectors of the graph Laplacian. Moreover, we provide differential geometric and random matrix theoretic arguments to support our approach.\\n\\nOur contributions are as follows. We present a spectral algorithm, LEGO (Laplacian Eigenvector Gradi- ent Orthogonalization), for estimating tangent spaces at each data point by orthogonalizing the gradients of low-frequency global eigenvectors of the graph Laplacian derived from a noisy point cloud. Through comprehensive experiments we show that LEGO yields tangent space estimates that are significantly more robust to noise than those obtained via LPCA. We also demonstrate that this increased robustness results in significant improvements across multiple downstream tasks, including manifold learning [1, 2, 35, 3, 5, 36], boundary detection [37, 38, 39], and local intrinsic dimension estimation [13].\\n\\nOn the theoretical front, we offer two complementary justifications for our approach. First, we provide a differential geometric argument where we adopt a noise model in which clean data points lie on a d- dimensional smooth submanifold B in Rd+k, while the noisy observations lie in a tubular neighborhood T εr around B, where r is any number bounded by the global reach of B [40, 41] and ε ∈ (0,1) controls the tube width. In practice, r represents the maximum noise and and ε is a parameter that controls the noise level. In particular, we assume that noise perturbs data in directions normal to B. In this setting, the “horizontal space” at a noisy point—the subspace orthogonal to the noise direction—approximates the true tangent space of the corresponding clean point. Thus, estimating the horizontal space provides a principled approach to robust tangent space estimation. To formalize this approach, we study the eigenfunctions of the Laplacian on the tubular neighborhood T εr of B.\\n\\nSpecifically, we establish upper and lower bounds on the eigenvalue λ associated with an eigenfunction ϕ in terms of its horizontal and vertical energies, EB(ϕ) and E⊥ B(ϕ), which quantify the net gradient of ϕ across the horizontal spaces and the noise directions, respectively. These bounds indicate that for small ε, λ approximately scales as Ω(ε−2E⊥ B(ϕ)) with respect to the vertical energy of ϕ, and as O(EB(ϕ)) with respect to the horizontal energy. As a result, eigenfunctions with significant gradient across tube cross- sections necessarily correspond to large eigenvalues. Conversely, gradients of eigenfunctions associated with small eigenvalues are largely confined to the horizontal spaces. The practical implication is that the gradients of the low-frequency eigenvectors of the graph Laplacian, constructed from noisy data, exhibit relatively small components along noise directions, and thus their orthogonalization may provide a robust estimate of the tangent spaces.\\n\\nSecond, we provide a random matrix theoretic argument where we adopt an information plus noise- type model in which the clean data is injected with sub-Gaussian noise with variance proxy ε. Our data model is reminiscent of that presented in [42], with a key distinction being that our data dimension is held constant while ε = o(1) in the limit as the number of data points tends to infinity. This model generalizes from the case where the clean data lies on an embedded submanifold and the noise is confined to directions orthogonal to the tangent spaces. Using a Gaussian kernel with fixed bandwidth s, we construct the adjacency matrices and derive the corresponding random walk graph Laplacians, L for the clean data and L for the noisy data [43, 44].\\n\\nBy adapting techniques from the random graph literature (see, e.g., [45]), assuming that the variance √ proxy ε scales as O(1/ nlogn), we prove that the noisy Laplacian L converges to its clean counterpart L in operator norm at a rate of n−1/2 i.e., ∥L−L∥2 = O(n−1/2) with high probability. By the Davis-Kahan theorem [46], it follows that the eigenvectors of L remain close to those of L, provided the eigengaps of\\n\\nROBUST TANGENT SPACE ESTIMATION VIA LAPLACIAN EIGENVECTOR GRADIENT ORTHOGONALIZATION 3\\n\\nThis provides empirical and theoretical support for using gradients of graph Laplacian eigenvectors to estimate local tangent spaces on data manifolds.

Our data model is reminiscent of that presented in [42], with a key distinction being that our data dimension is held constant while ε = o(1) in the limit as the number of data points tends to infinity. This model generalizes from the case where the clean data lies on an embedded submanifold and the noise is confined to directions orthogonal to the tangent spaces. Using a Gaussian kernel with fixed bandwidth s, we construct the adjacency matrices and derive the corresponding random walk graph Laplacians, L for the clean data and L for the noisy data [43, 44].\\n\\nBy adapting techniques from the random graph literature (see, e.g., [45]), assuming that the variance √ proxy ε scales as O(1/ nlogn), we prove that the noisy Laplacian L converges to its clean counterpart L in operator norm at a rate of n−1/2 i.e., ∥L−L∥2 = O(n−1/2) with high probability. By the Davis-Kahan theorem [46], it follows that the eigenvectors of L remain close to those of L, provided the eigengaps of\\n\\nD. KOHLI, S.J. ROBERTSON, G. MISHNE, A.

In the submanifold setting, classical spectral results such as Weyl’s law (e.g., see [47]) imply that eigengaps tend to shrink deeper in the spectrum.

High-aspect ratio Swiss roll and a truncated torus. We begin with two synthetic datasets: a high–aspect-ratio Swiss roll and a truncated torus. For the Swiss roll, we generate n = 10700 uniformly distributed points in R3, forming the clean dataset Y (Figure 3a). Each point is perturbed by adding uniform noise in the direction normal to the underlying tangent space. Specifically, the noisy data points are given by Xj = Yj +ηjνj, where νj is outward normal to the tangent space at Yj and the coefficient ηj is uniformly distributed in (−ε,ε) where ε = 0.0175. The resulting noisy dataset X is shown in Figure 3a.\\n\\nFor the truncated torus, we sample n = 3617 uniformly distributed points on a subset of the torus in R3 as shown in Figure 4a. Here, each data point Yj is parameterized by (u,v) ∈ [0,2π)2 i.e. Yj ≡ Yj(uj,vj). We corrupt the clean data with heteroskedastic noise added in the normal direction to the tangent space at each point. The noisy data points are given by Xj = Yj + ηjνj, where νj is the outward normal direction to the tangent space at Yj and the coefficient ηj is uniformly distributed in (−ε(uj),ε(uj)) where ε(u) = 10−2 + 2.5 × 10−3(1 + cos(2u)).

High-aspect ratio Swiss roll and a truncated torus. We begin with two synthetic datasets: a high–aspect-ratio Swiss roll and a truncated torus. For the Swiss roll, we generate n = 10700 uniformly distributed points in R3, forming the clean dataset Y (Figure 3a). Each point is perturbed by adding uniform noise in the direction normal to the underlying tangent space. Specifically, the noisy data points are given by Xj = Yj +ηjνj, where νj is outward normal to the tangent space at Yj and the coefficient ηj is uniformly distributed in (−ε,ε) where ε = 0.0175. The resulting noisy dataset X is shown in Figure 3a.\\n\\nFor the truncated torus, we sample n = 3617 uniformly distributed points on a subset of the torus in R3 as shown in Figure 4a. Here, each data point Yj is parameterized by (u,v) ∈ [0,2π)2 i.e. Yj ≡ Yj(uj,vj). We corrupt the clean data with heteroskedastic noise added in the normal direction to the tangent space at each point. The noisy data points are given by Xj = Yj + ηjνj, where νj is the outward normal direction to the tangent space at Yj and the coefficient ηj is uniformly distributed in (−ε(uj),ε(uj)) where ε(u) = 10−2 + 2.5 × 10−3(1 + cos(2u)). The noisy dataset X is shown in Figure 4a.\\n\\nFor both datasets, we estimate an orthonormal basis Qj of the 2-dimensional tangent space at each Xj using LPCA and LEGO, and then compute the discrepancy Dj (Eq. 44) between the estimates Qj and the ground-truth Q∗ j, as shown in Figure 3b and 4b. These results show that LEGO produces significantly more accurate estimates while LPCA estimates are highly sensitive to noise.

Latent reasoning has emerged as an efficient alternative that internalizes the thought pro- cess, but it suffers from a critical lack of supervision, limiting its effectiveness on complex, natural-language reasoning traces. In this work we propose KAVA, the first framework that bridges this gap by distilling knowledge directly from a compressed KV-cache of the teacher into a latent-reasoning student via self- distillation, leveraging the representational flexibility of continuous latent tokens to align stepwise KV trajectories.

Latent reasoning has emerged as an efficient alternative that internalizes the thought pro- cess, but it suffers from a critical lack of supervision, limiting its effectiveness on complex, natural-language reasoning traces. In this work we propose KAVA, the first framework that bridges this gap by distilling knowledge directly from a compressed KV-cache of the teacher into a latent-reasoning student via self- distillation, leveraging the representational flexibility of continuous latent tokens to align stepwise KV trajectories. We show that the abstract, unstructured knowl- edge within compressed KV-cache, which lacks direct token correspondence, can serve as a rich supervisory signal for a latent reasoning student. Empirically, the approach consistently outperforms strong latent baselines, exhibits markedly smaller degradation from equation-only to natural-language traces, and scales to larger backbones while preserving efficiency.

Traditional reasoning LLMs often rely on generating explicit intermediate steps in language to solve complex reasoning tasks. Recent work shifts reasoning from discrete text tokens to latent continuous tokens, where models perform iterative computation internally with- out generating external text (Chen et al., 2025; Zhu et al., 2025). Early work validated the benefit of extra computation through unstructured means, such as learnable pause tokens (Goyal et al., 2024) or even semantically meaningless filler tokens (Pfau et al., 2024), which improved performance on rea- soning tasks by simply extending the model’s processing time implicitly. Building on this implicit- compute view, iCoT moves from explicit to implicit CoT via distillation (Deng et al., 2023) and curriculum (Deng et al., 2024), progressively removing CoT while aligning internal states around answer prediction. This allows the model to internalize reasoning without generating text rationales at inference.

Unlike chain-of-thought (CoT) reasoning traces, latent reasoning lacks direct supervision because latent traces are unobserved during training.

To address this, we leverage the observed reasoning traces C to guide latent reasoning during training, as illustrated in Fig. 3.

To mitigate this issue, we use Jacobi iteration over latent tokens to improve training and inference efficiency as proposed by Wu et al. (2025).

PCCoT uses T < M, so that total number of forward passes is reduced from the number of latent tokens M to the number of iterations T.

However, there no longer exists a correspondence between the resulting cache and hard tokens. For that reason, we cannot ap- ply standard ways of distillation, matching the activations of the teacher and student model. Instead, we propose distilling the keys and values directly.\\n\\nTo this end, we distill the latent reasoning cache to match the compressed teacher’s cache, effectively guiding the latent model to approximate the full reasoning process in a more efficient and abstract form. We combine the loss for the keys and values in equal weights to get the final term of Eq. 2:\\n\\n,\\n\\n1For the group-query attention setting multiple queries are sharing the same key-value pair.

We conduct experiments using the pretrained LLaMA3.2-1b-Instruct, LLaMA3.2-3b-Instruct and Qwen2.5-0.5b-Instruct (Grattafiori et al., 2024; Team, 2024) models and fine-tune them using LoRA (Hu et al., 2022). We follow Shen et al. (2025) and Wu et al. (2025) by using the same LoRA setup (rank 128 with alpha value 32 and dropout 0.1) for all the experiments. We employ PCCoT, the approach proposed by Wu et al.

Both datasets are augmented versions GSM8k (Cobbe et al., 2021), containing 385k training ex- amples, with traces generated by GPT-4. GSM8k-AUG is then further processed by keeping only equations and removing all natural language from the traces. We provide a detailed description of the datasets in Appendix B. For in-distribution evaluation, we assess all models on the test split of the original GSM8k dataset (Cobbe et al., 2021). For zero-shot evaluation, we assess model gener- alization on two benchmarks: GSM8k-Hard (Gao et al., 2023) and SVAMP (Patel et al., 2021).\\n\\nHyperparameters.

For that reason, we skip the PCCoT results in the table as they would be similar to ours. Our method achieves better efficiency than CoT, requiring between 62% and 92% fewer forward passes per question compared to Full CoT.\\n\\n4.3 ABLATION STUDIES\\n\\nWe select LLAMA3.2-1B-INSTRUCT to conduct ablation studies for our method.

However, we observed that better performance may be achieved when using MSE loss on other datasets (see Appendix C for the detailed hyperparameters used for all models and datasets).\\n\\nKV Eviction. We follow Cai et al. (2025) in using λ = 0.1 (see Eq. 4) in R-KV eviction for all the experiments. As an ablation study we consider the two extremes: cosine-only (λ = 0) and attention-only (λ = 1). These cases correspond to choosing the keys and values based on diversity or importance only. Furthermore, we use a simple baseline of cropping the full CoT trace from the right, that is we only keep first M tokens of the teacher’s cache for distillation. We report the results in Figure 5.

More examples of the decoded traces are given in the Appendix E. Interestingly, the decoded latent trace is often identical to the trace generated by the teacher model, underlining the importance of the teacher guidance. In particular cases, as shown in the table, a reasoning step can be expressed in two equivalent forms (e.g. <<650*2=1300>> and <<2*650=1300>>). In regular CoT, this ambiguity is resolved after sampling a unique prefix of one of the variants, however, there is no explicit mechanism allowing for such resolution in a latent CoT.

In contrast, models trained on the GSM8k-AUG-NL dataset resist this straightforward read-out method. We hypothesize that this is caused by the KV-cache distillation employed by KAVA —in a dataset with shorter traces, such as GSM8k-AUG, most of the time the KV-cache re- tains all of its content after eviction. On longer traces, such as the ones found in GSM8k-AUG-NL, not all content of the KV-cache is preserved, and, furthermore, each latent thought’s distillation tar- get may consist of keys and values originating from different tokens of the teacher’s CoT. This can prevent latent thought to hard token correspondence from arising.\\n\\n5.2 TEACHER-STUDENT KV-CACHE CORRESPONDENCE\\n\\nFigure 7: Cosine similarity of Keys in the latent CoT with Keys of the ground truth averaged across heads and layers.

The results for Keys, averaged over attention heads and layers are presented in the Fig. 7. We observe that when comparing to the KV- cache after eviction, the similarities near the diagonal (x = y) tend to be higher, which is expected, as it is encouraged by the KV distillation. Furthermore, the values to the right of the diagonal are higher when comparing with the full CoT, which is desired, as this represents the compression of the original CoT (i.e. the key of some n-th latent token is similar to the key of an m-th hard token where n < m). The figure for Values and the full visualization of the similarities across layers and heads can be found in the Appendix D.\\n\\nPreprint. Under Review.\\n\\nTable 5: Decoding the latent thoughts. A validation prompt is used: “Mrs. Taylor bought two smart televisions that cost $650 each. If the total sales price had a 25% discount, how much did Mrs. Taylor pay for the two televisions?”. Latent thoughts 16-24 are not shown due to their limited semantic value. 3 tokens with the highest logits are shown for each latent thought. Tokens T1, T2, T3, T4, T5, T6, T7 stand for total, cost, dollars, discount, original, gross, and price respectively. Following CODI, the teacher is trained on traces omitting the last step.\\n\\nTopK 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 Answer GSM8K-Aug 1 650 * 2 = 130 0 >> << of 0 * * >> = = 2 2 + 650 * 650 >> .

In contrast, models trained on the GSM8k-AUG-NL dataset resist this straightforward read-out method. We hypothesize that this is caused by the KV-cache distillation employed by KAVA —in a dataset with shorter traces, such as GSM8k-AUG, most of the time the KV-cache re- tains all of its content after eviction. On longer traces, such as the ones found in GSM8k-AUG-NL, not all content of the KV-cache is preserved, and, furthermore, each latent thought’s distillation tar- get may consist of keys and values originating from different tokens of the teacher’s CoT. This can prevent latent thought to hard token correspondence from arising.\\n\\n5.2 TEACHER-STUDENT KV-CACHE CORRESPONDENCE\\n\\nFigure 7: Cosine similarity of Keys in the latent CoT with Keys of the ground truth averaged across heads and layers.

Our central con- tribution is the demonstration that a compressed KV-cache, despite losing direct token correspon- dence, can serve as a rich, stepwise supervisory signal for a latent reasoning student. By aligning the student’s latent trajectory with the teacher’s internal reasoning dynamics in KV space, KAVA over- comes the limitations of token-level distillation and the inefficiencies of verbose Chain-of-Thought (CoT) traces. KAVA consistently outperforms strong latent reasoning baselines, scales effectively to larger backbones, and shows robust performance on natural-language reasoning datasets where prior methods often struggle. While the advancement of latent reasoning is linked to the availability of large-scale training data to instill novel reasoning dynamics, our work establishes compressed KV-cache distillation as a scalable and effective supervision technique for developing efficient and powerful reasoning models.\\n\\nREFERENCES\\n\\nZefan Cai, Yichi Zhang, Bofei Gao, Yuliang Liu, Yucheng Li, Tianyu Liu, Keming Lu, Wayne Xiong, Yue Dong, Junjie Hu, et al.

You can think of this initial chapter as a recipe you can just follow. It\\'s a \"shoot first, ask questions later\" kind of post.\\n\\nYou\\'ll learn how to:\\n\\nLoad a quantized model using BitsAndBytes\\n\\nConfigure low-rank adapters (LoRA) using Hugging Face\\'s peft\\n\\nLoad and format a dataset\\n\\nFine-tune the model using the supervised fine-tuning trainer (SFTTrainer) from Hugging Face\\'s trl\\n\\nUse the fine-tuned model to generate a sentence\\n\\nJupyter Notebook\\n\\nThe Jupyter notebook corresponding to this post is part of the official Fine-Tuning LLMs repository on GitHub. You can also run it directly in Google Colab\\n\\nSetup\\n\\nIf you\\'re running it on Colab, you\\'ll need to pip install a few libraries: datasets, bitsandbytes, and trl.\\n\\nFor better reproducibility during training, however, use the pinned versions instead:\\n\\n#!pip install datasets bitsandbytes trl !pip install transformers==4.55.2 peft==0.17.0 accelerate==1.10.0 trl==0.21.0 bitsandbytes==0.47.0 datasets==4.0.0 huggingface-hub==0.34.4 safetensors==0.6.2 pandas==2.2.2 matplotlib==3.10.0 numpy==2.0.2\\n\\nImports\\n\\nFor the sake of organization, all libraries needed throughout the code used are imported at its very start. For this post, we\\'ll need the following imports:\\n\\nimport os import torch from datasets import load_dataset from peft import get_peft_model, LoraConfig, prepare_model_for_kbit_training from transformers import AutoModelForCausalLM, AutoTokenizer, BitsAndBytesConfig from trl import SFTConfig, SFTTrainer\\n\\nLoading a Quantized Base Model\\n\\nWe start by loading a quantized model, so it takes up less space in the GPU\\'s RAM. A quantized model replaces the original weights with approximate values that are represented by fewer bits. The simplest and most straightforward way to quantize a model is to turn its weights from 32-bit floating-point (FP32) numbers into 4-bit floating-point numbers (NF4). This simple yet powerful change already reduces the model\\'s memory footprint by roughly a factor of eight.\\n\\nWe can use an instance of BitsAndBytesConfig as the quantization_config argument while loading a model using the from_pretrained() method. To keep it flexible, so you can try it out with any other model of your choice, we\\'re using Hugging Face\\'s AutoModelForCausalLM. The repo you choose to use determines the model being loaded.\\n\\nWithout further ado, here\\'s our quantized model being loaded:\\n\\nbnb_config = BitsAndBytesConfig( load_in_4bit=True, bnb_4bit_quant_type=\"nf4\", bnb_4bit_use_double_quant=True, bnb_4bit_compute_dtype=torch.float32 ) repo_id = \\'microsoft/Phi-3-mini-4k-instruct\\' model = AutoModelForCausalLM.from_pretrained( repo_id, device_map=\"cuda:0\", quantization_config=bnb_config )\\n\\n\"The Phi-3-Mini-4K-Instruct is a 3.8B parameters, lightweight, state-of-the-art open model trained with the Phi-3 datasets that includes both synthetic data and the filtered publicly available websites data with a focus on high-quality and reasoning dense properties. The model belongs to the Phi-3 family with the Mini version in two variants 4K and 128K which is the context length (in tokens) that it can support.\" Source: Hugging Face Hub\\n\\nOnce the model is loaded, you can see how much space it occupies in memory using the get_memory_footprint() method.\\n\\nprint(model.get_memory_footprint()/1e6)\\n\\n2206.347264\\n\\nEven though it\\'s been quantized, the model still takes up a bit more than 2 gigabytes of RAM. The quantization procedure focuses on the linear layers within the Transformer decoder blocks (also referred to as \"layers\" in some cases):\\n\\nmodel\\n\\nPhi3ForCausalLM( (model): Phi3Model( (embed_tokens): Embedding(32064, 3072, padding_idx=32000) (embed_dropout): Dropout(p=0.0, inplace=False) (layers): ModuleList( (0-31): 32 x Phi3DecoderLayer( (self_attn): Phi3Attention( (o_proj): Linear4bit(in_features=3072, out_features=3072, bias=False) <1> (qkv_proj): Linear4bit(in_features=3072, out_features=9216, bias=False) <1> (rotary_emb): Phi3RotaryEmbedding() ) (mlp): Phi3MLP( (gate_up_proj): Linear4bit(in_features=3072, out_features=16384, bias=False) <1> (down_proj): Linear4bit(in_features=8192, out_features=3072, bias=False) <1> (activation_fn): SiLU() ) (input_layernorm): Phi3RMSNorm((3072,), eps=1e-05) (resid_attn_dropout): Dropout(p=0.0, inplace=False) (resid_mlp_dropout): Dropout(p=0.0, inplace=False) (post_attention_layernorm): Phi3RMSNorm((3072,), eps=1e-05) ) ) (norm): Phi3RMSNorm((3072,), eps=1e-05) ) (lm_head): Linear(in_features=3072, out_features=32064, bias=False) )\\n\\n<1> Quantized layers\\n\\nA quantized model can be used directly for inference, but it cannot be trained any further. Those pesky Linear4bit layers take up much less space, which is the whole point of quantization; however, we cannot update them.\\n\\nWe need to add something else to our mix, a sprinkle of adapters.\\n\\nSetting Up Low-Rank Adapters (LoRA)\\n\\nLow-rank adapters can be attached to each and every one of the quantized layers. The adapters are mostly regular Linear layers that can be easily updated as usual. The clever trick in this case is that these adapters are significantly smaller than the layers that have been quantized.\\n\\nSince the quantized layers are frozen (they cannot be updated), setting up LoRA adapters on a quantized model drastically reduces the total number of trainable parameters to just 1% (or less) of its original size.\\n\\nWe can set up LoRA adapters in three easy steps:\\n\\nCall prepare_model_for_kbit_training() to improve numerical stability during training.\\n\\nCreate an instance of LoraConfig.\\n\\nApply the configuration to the quantized base model using the get_peft_model() method.\\n\\nLet\\'s try it out with our model:\\n\\nmodel = prepare_model_for_kbit_training(model) config = LoraConfig( # the rank of the adapter, the lower the fewer parameters you\\'ll need to train r=8, lora_alpha=16, # multiplier, usually 2*r bias=\"none\", lora_dropout=0.05, task_type=\"CAUSAL_LM\", # Newer models, such as Phi-3 at time of writing, may require # manually setting target modules target_modules=[\\'o_proj\\', \\'qkv_proj\\', \\'gate_up_proj\\', \\'down_proj\\'], ) model = get_peft_model(model, config) model\\n\\nPeftModelForCausalLM( (base_model): LoraModel( (model): Phi3ForCausalLM( (model): Phi3Model( (embed_tokens): Embedding(32064, 3072, padding_idx=32000) (embed_dropout): Dropout(p=0.0, inplace=False) (layers): ModuleList( (0-31): 32 x Phi3DecoderLayer( (self_attn): Phi3Attention( (o_proj): lora.Linear4bit( <1> (base_layer): Linear4bit(in_features=3072, out_features=3072, bias=False) (lora_dropout): ModuleDict((default): Dropout(p=0.05, inplace=False)) (lora_A): ModuleDict( (default): Linear(in_features=3072, out_features=8, bias=False) ) (lora_B): ModuleDict( (default): Linear(in_features=8, out_features=3072, bias=False) ) (lora_embedding_A): ParameterDict() (lora_embedding_B): ParameterDict() (lora_magnitude_vector): ModuleDict() ) (qkv_proj): lora.Linear4bit(...) <1> (rotary_emb): Phi3RotaryEmbedding() ) (mlp): Phi3MLP( (gate_up_proj): lora.Linear4bit(...) <1> (down_proj): lora.Linear4bit(...) <1> (activation_fn): SiLU() ) (input_layernorm): Phi3RMSNorm((3072,), eps=1e-05) (resid_attn_dropout): Dropout(p=0.0, inplace=False) (resid_mlp_dropout): Dropout(p=0.0, inplace=False) (post_attention_layernorm): Phi3RMSNorm((3072,), eps=1e-05) ) ) (norm): Phi3RMSNorm((3072,), eps=1e-05) ) (lm_head): Linear(in_features=3072, out_features=32064, bias=False) ) ) )\\n\\n<1> LoRA adapters\\n\\nThe output of the other three LoRA layers (qkv_proj, gate_up_proj, and down_proj) was suppressed to shorten the output.\\n\\nDid you get the following error? ValueError: Please specify `target_modules` in `peft_config` Most likely, you don\\'t need to specify the target_modules if you\\'re using one of the well-known models. The peft library takes care of it by automatically choosing the appropriate targets. However, there may be a gap between the time a popular model is released and the time the library gets updated. So, if you get the error above, look for the quantized layers in your model and list their names in the target_modules argument.\\n\\nThe quantized layers (Linear4bit) have turned into lora.Linear4bit modules where the quantized layer itself became the base_layer with some regular Linear layers (lora_A and lora_B) added to the mix.\\n\\nThese extra layers would make the model only slightly larger. However, the model preparation function (prepare_model_for_kbit_training()) turned every non-quantized layer to full precision (FP32), thus resulting in a 30% larger model:\\n\\nprint(model.get_memory_footprint()/1e6)\\n\\n2651.080704\\n\\nSince most parameters are frozen, only a tiny fraction of the total number of parameters are currently trainable, thanks to LoRA!\\n\\ntrain_p, tot_p = model.get_nb_trainable_parameters() print(f\\'Trainable parameters: {train_p/1e6:.2f}M\\') print(f\\'Total parameters: {tot_p/1e6:.2f}M\\') print(f\\'% of trainable parameters: {100*train_p/tot_p:.2f}%\\')\\n\\nTrainable parameters: 12.58M Total parameters: 3833.66M % of trainable parameters: 0.33%\\n\\nThe model is ready to be fine-tuned, but we are still missing one key component: our dataset.\\n\\nFormatting Your Dataset\\n\\n\"Like Yoda, speak, you must. Hrmmm.\" Master Yoda\\n\\nThe dataset yoda_sentences consists of 720 sentences translated from English to Yoda-speak. The dataset is hosted on the Hugging Face Hub and we can easily load it using the load_dataset() method from the Hugging Face datasets library:\\n\\ndataset = load_dataset(\"dvgodoy/yoda_sentences\", split=\"train\") dataset\\n\\nDataset({ features: [\\'sentence\\', \\'translation\\', \\'translation_extra\\'], num_rows: 720 })\\n\\nThe dataset has three columns:\\n\\noriginal English sentence (sentence)\\n\\nbasic translation to Yoda-speak (translation)\\n\\nenhanced translation including typical Yesss and Hrrmm interjections (translation_extra)\\n\\ndataset[0]\\n\\n{\\'sentence\\': \\'The birch canoe slid on the smooth planks.\\', \\'translation\\': \\'On the smooth planks, the birch canoe slid.\\', \\'translation_extra\\': \\'On the smooth planks, the birch canoe slid. Yes, hrrrm.\\'}\\n\\nThe SFTTrainer we\\'ll be using to fine-tune the model can automatically handle datasets in conversational format.\\n\\n{\"messages\":[ {\"role\": \"system\", \"content\": \"\"}, {\"role\": \"user\", \"content\": \"\"}, {\"role\": \"assistant\", \"content\": \"\"} ]}\\n\\nIMPORTANT UPDATE: unfortunately, in more recent versions of the trl library, the \"instruction\" format is not properly supported anymore, thus leading to the chat template not being applied to the dataset. In order to avoid this issue, we can convert the dataset to the \"conversational\" format.\\n\\nSo, we\\'ll convert the dataset to the conversational format using the format_dataset() function below:\\n\\n# Adapted from trl.extras.dataset_formatting.instructions_formatting_function # Converts dataset from prompt/completion format (not supported anymore) # to the conversational format def format_dataset(examples): if isinstance(examples[\"prompt\"], list): output_texts = [] for i in range(len(examples[\"prompt\"])): converted_sample = [ {\"role\": \"user\", \"content\": examples[\"prompt\"][i]}, {\"role\": \"assistant\", \"content\": examples[\"completion\"][i]}, ] output_texts.append(converted_sample) return {\\'messages\\': output_texts} else: converted_sample = [ {\"role\": \"user\", \"content\": examples[\"prompt\"]}, {\"role\": \"assistant\", \"content\": examples[\"completion\"]}, ] return {\\'messages\\': converted_sample}\\n\\ndataset = dataset.rename_column(\"sentence\", \"prompt\") dataset = dataset.rename_column(\"translation_extra\", \"completion\") dataset = dataset.map(format_dataset) dataset = dataset.remove_columns([\\'prompt\\', \\'completion\\', \\'translation\\']) messages = dataset[0][\\'messages\\'] messages\\n\\n[{\\'role\\': \\'user\\', \\'content\\': \\'The birch canoe slid on the smooth planks.\\'}, {\\'role\\': \\'assistant\\', \\'content\\': \\'On the smooth planks, the birch canoe slid. Yes, hrrrm.\\'}]\\n\\nTokenizer\\n\\nBefore moving into the actual training, we still need to load the tokenizer that corresponds to our model. The tokenizer is an important part of this process, determining how to convert text into tokens in the same way used to train the model.\\n\\nFor instruction/chat models, the tokenizer also contains its corresponding chat template that specifies:\\n\\nWhich special tokens should be used, and where they should be placed.\\n\\nWhere the system directives, user prompt, and model response should be placed.\\n\\nWhat is the generation prompt, that is, the special token that triggers the model\\'s response (more on that in the \"Querying the Model\" section)\\n\\nIMPORTANT UPDATE: due to changes in the default collator used by the SFTTrainer class while building the dataset, the EOS token (which is, in Phi-3, the same as the PAD token) was masked in the labels too thus leading to the model not being able to properly stop token generation.\\n\\nIn order to address this change, we can assign the UNK token to the PAD token, so the EOS token becomes unique and therefore not masked as part of the labels.\\n\\ntokenizer = AutoTokenizer.from_pretrained(repo_id) tokenizer.pad_token = tokenizer.unk_token tokenizer.pad_token_id = tokenizer.unk_token_id tokenizer.chat_template\\n\\n\"{% for message in messages %} {% if message[\\'role\\'] ## \\'system\\' %} {{\\'<|system|>\\\\n\\' + message[\\'content\\'] + \\'<|end|>\\\\n\\'}} {% elif message[\\'role\\'] ## \\'user\\' %} {{\\'<|user|>\\\\n\\' + message[\\'content\\'] + \\'<|end|>\\\\n\\'}} {% elif message[\\'role\\'] ## \\'assistant\\' %} {{\\'<|assistant|>\\\\n\\' + message[\\'content\\'] + \\'<|end|>\\\\n\\'}} {% endif %} {% endfor %} {% if add_generation_prompt %} {{ \\'<|assistant|>\\\\n\\' }}{% else %}{{ eos_token }} {% endif %}\"\\n\\nNever mind the seemingly overcomplicated template (I have added line breaks and indentation to it so it\\'s easier to read). It simply organizes the messages into a coherent block with the appropriate tags, as shown below (tokenize=False ensures we get readable text back instead of a numeric sequence of token IDs):\\n\\nprint(tokenizer.apply_chat_template(messages, tokenize=False))\\n\\n<|user|> The birch canoe slid on the smooth planks.<|end|> <|assistant|> On the smooth planks, the birch canoe slid. Yes, hrrrm.<|end|> <|endoftext|>\\n\\nNotice that each interaction is wrapped in either <|user|> or <|assistant|> tokens at the beginning and <|end|> at the end. Moreover, the <|endoftext|> token indicates the end of the whole block.\\n\\nDifferent models will have different templates and tokens to indicate the beginning and end of sentences and blocks.\\n\\nWe\\'re now ready to tackle the actual fine-tuning!\\n\\nFine-Tuning with SFTTrainer\\n\\nFine-tuning a model, whether large or otherwise, follows exactly the same training procedure as training a model from scratch. We could write our own training loop in pure PyTorch, or we could use Hugging Face\\'s Trainer to fine-tune our model.\\n\\nIt is much easier, however, to use SFTTrainer instead (which uses Trainer underneath, by the way), since it takes care of most of the nitty-gritty details for us, as long as we provide it with the following four arguments:\\n\\na model\\n\\na tokenizer\\n\\na dataset\\n\\na configuration object\\n\\nWe\\'ve already got the first three elements; let\\'s work on the last one.\\n\\nSFTConfig\\n\\nThere are many parameters that we can set in the configuration object. We have divided them into four groups:\\n\\nMemory usage optimization parameters related to gradient accumulation and checkpointing\\n\\nDataset-related arguments, such as the max_seq_length required by your data, and whether you are packing or not the sequences\\n\\nTypical training parameters such as the learning_rate and the num_train_epochs\\n\\nEnvironment and logging parameters such as output_dir (this will be the name of the model if you choose to push it to the Hugging Face Hub once it\\'s trained), logging_dir, and logging_steps.\\n\\nWhile the learning rate is a very important parameter (as a starting point, you can try the learning rate used to train the base model in the first place), it\\'s actually the maximum sequence length that\\'s more likely to cause out-of-memory issues.\\n\\nMake sure to always pick the shortest possible max_seq_length that makes sense for your use case. In ours, the sentences—both in English and Yoda-speak—are quite short, and a sequence of 64 tokens is more than enough to cover the prompt, the completion, and the added special tokens.\\n\\nFlash attention (which, unfortunately, isn\\'t supported in Colab), allows for more flexibility in working with longer sequences, avoiding the potential issue of OOM errors.\\n\\nIMPORTANT UPDATE: The release of trl version 0.20 brought several changes to the SFTConfig:\\n\\npacking is performed differently than it was, unless packing_strategy=\\'wrapped\\' is set;\\n\\nthe max_seq_length argument was renamed to max_length;\\n\\nthe bf16 defaults to True but, at the time of this update (Aug/2025), it didn\\'t check if the BF16 type was actually available or not, so it\\'s included in the configuration now.\\n\\nsft_config = SFTConfig( ## GROUP 1: Memory usage # These arguments will squeeze the most out of your GPU\\'s RAM # Checkpointing gradient_checkpointing=True, # this saves a LOT of memory # Set this to avoid exceptions in newer versions of PyTorch gradient_checkpointing_kwargs={\\'use_reentrant\\': False}, # Gradient Accumulation / Batch size # Actual batch (for updating) is same (1x) as micro-batch size gradient_accumulation_steps=1, # The initial (micro) batch size to start off with per_device_train_batch_size=16, # If batch size would cause OOM, halves its size until it works auto_find_batch_size=True, ## GROUP 2: Dataset-related max_length=64, # renamed in v0.20 # Dataset # packing a dataset means no padding is needed packing=True, packing_strategy=\\'wrapped\\', # added to approximate original packing behavior ## GROUP 3: These are typical training parameters num_train_epochs=10, learning_rate=3e-4, # Optimizer # 8-bit Adam optimizer - doesn\\'t help much if you\\'re using LoRA! optim=\\'paged_adamw_8bit\\', ## GROUP 4: Logging parameters logging_steps=10, logging_dir=\\'./logs\\', output_dir=\\'./phi3-mini-yoda-adapter\\', report_to=\\'none\\'. # ensures bf16 (the new default) is only used when it is actually available bf16=torch.cuda.is_bf16_supported(including_emulation=False) )\\n\\nSFTTrainer\\n\\n\"It is training time!\" The Hulk\\n\\nIMPORTANT UPDATE: The current version of trl (0.21) has a known issue where training fails if the LoRA configuration has already been applied to the model, as the trainer freezes the whole model, including the adapters.\\n\\nHowever, it works as expected when the configuration is passed as the peft_config argument to the trainer, since it is applied after freezing the existing layers.\\n\\nIf the model already contains the adapters, as in our case, training still works, but we need to use the underlying original model instead (model.base_model.model) to ensure the save_model() method functions correctly.\\n\\nWe can now finally create an instance of the supervised fine-tuning trainer:\\n\\ntrainer = SFTTrainer( model=model.base_model.model, # the underlying Phi-3 model peft_config=config, # added to fix issue in TRL>=0.20 processing_class=tokenizer, args=sft_config, train_dataset=dataset, )\\n\\nThe SFTTrainer had already preprocessed our dataset, so we can take a look inside and see how each mini-batch was assembled:\\n\\ndl = trainer.get_train_dataloader() batch = next(iter(dl))\\n\\nLet\\'s check the labels; after all, we didn\\'t provide any, did we?\\n\\nbatch[\\'input_ids\\'][0], batch[\\'labels\\'][0]\\n\\n(tensor([ 1746, 29892, 278, 10435, 3147, 698, 287, 29889, 32007, 32000, 32000, 32010, 10987, 278, 3252, 262, 1058, 380, 1772, 278, 282, 799, 29880, 18873, 1265, 29889, 32007, 32001, 11644, 380, 1772, 278, 282, 799, 29880, 18873, 1265, 29892, 1284, 278, 3252, 262, 29892, 366, 1818, 29889, 3869, 29892, 298, 21478, 1758, 29889, 32007, 32000, 32000, 32010, 315, 329, 278, 13793, 393, 7868, 29879, 278], device=\\'cuda:0\\'), tensor([ 1746, 29892, 278, 10435, 3147, 698, 287, 29889, 32007, 32000, 32000, 32010, 10987, 278, 3252, 262, 1058, 380, 1772, 278, 282, 799, 29880, 18873, 1265, 29889, 32007, 32001, 11644, 380, 1772, 278, 282, 799, 29880, 18873, 1265, 29892, 1284, 278, 3252, 262, 29892, 366, 1818, 29889, 3869, 29892, 298, 21478, 1758, 29889, 32007, 32000, 32000, 32010, 315, 329, 278, 13793, 393, 7868, 29879, 278], device=\\'cuda:0\\'))\\n\\nThe labels were added automatically, and they\\'re exactly the same as the inputs.

It takes about 35 minutes to complete the training process.\\n\\nNext, we call the train() method and wait:\\n\\ntrainer.train()\\n\\nStep Training Loss 10 2.990700 20 1.789500 30 1.581700 40 1.458300 50 1.362300 100 0.607900 150 0.353600 200 0.277500 220 0.252400\\n\\nQuerying the Model\\n\\nNow, our model should be able to produce a Yoda-like sentence as a response to any short sentence we give it.\\n\\nSo, the model requires its inputs to be properly formatted. We need to build a list of \"messages\"—ours, from the user, in this case—and prompt the model to answer by indicating it\\'s its turn to write.\\n\\nThis is the purpose of the add_generation_prompt argument: it adds <|assistant|> to the end of the conversation, so the model can predict the next word—and continue doing so until it predicts an <|endoftext|> token.\\n\\nThe helper function below assembles a message (in the conversational format) and applies the chat template to it, appending the generation prompt to its end.\\n\\ndef gen_prompt(tokenizer, sentence): converted_sample = [{\"role\": \"user\", \"content\": sentence}] prompt = tokenizer.apply_chat_template( converted_sample, tokenize=False, add_generation_prompt=True ) return prompt\\n\\nLet\\'s try generating a prompt for an example sentence:\\n\\nsentence = \\'The Force is strong in you!\\' prompt = gen_prompt(tokenizer, sentence) print(prompt)\\n\\n<|user|> The Force is strong in you!<|end|> <|assistant|>\\n\\nThe prompt seems about right; let\\'s use it to generate a completion. The helper function below does the following:\\n\\nIt tokenizes the prompt into a tensor of token IDs (add_special_tokens is set to False because the tokens were already added by the chat template).\\n\\nIt sets the model to evaluation mode.\\n\\nIt calls the model\\'s generate() method to produce the output (generated token IDs).\\n\\nIf the model was trained using mixed-precision, we wrap the generation in the autocast() context manager, which automatically handles conversion between data types.\\n\\nIt decodes the generated token IDs back into readable text.\\n\\ndef generate(model, tokenizer, prompt, max_new_tokens=64, skip_special_tokens=False): tokenized_input = tokenizer( prompt, add_special_tokens=False, return_tensors=\"pt\" ).to(model.device) model.eval() # if it was trained using mixed precision, uses autocast context ctx = torch.autocast(device_type=model.device.type, dtype=model.dtype) \\\\ if model.dtype in [torch.float16, torch.bfloat16] else nullcontext() with ctx: gen_output = model.generate(**tokenized_input, eos_token_id=tokenizer.eos_token_id, max_new_tokens=max_new_tokens) output = tokenizer.batch_decode(gen_output, skip_special_tokens=skip_special_tokens) return output[0]\\n\\nNow, we can finally try out our model and see if it\\'s indeed capable of generating Yoda-speak.\\n\\nprint(generate(model, tokenizer, prompt))\\n\\n<|user|> The Force is strong in you!<|end|><|assistant|> Strong in you, the Force is. Yes, hrrmmm.<|end|>\\n\\nAwesome! It works! Like Yoda, the model speaks. Hrrrmm.\\n\\nCongratulations, you\\'ve fine-tuned your first LLM!\\n\\nNow, you\\'ve got a small adapter that can be loaded into an instance of the Phi-3 Mini 4K Instruct model to turn it into a Yoda translator! How cool is that?\\n\\nSaving the Adapter\\n\\nOnce the training is completed, you can save the adapter (and the tokenizer) to disk by calling the trainer\\'s save_model() method. It will save everything to the specified folder:\\n\\ntrainer.save_model(\\'local-phi3-mini-yoda-adapter\\')\\n\\nThe files that were saved include:\\n\\nthe adapter configuration (adapter_config.json) and weights (adapter_model.safetensors)—the adapter itself is just 50 MB in size\\n\\nthe training arguments (training_args.bin)\\n\\nthe tokenizer (tokenizer.json and tokenizer.model), its configuration (tokenizer_config.json), and its special tokens (added_tokens.json and speciak_tokens_map.json)\\n\\na README file\\n\\nIf you\\'d like to share your adapter with everyone, you can also push it to the Hugging Face Hub. First, log in using a token that has permission to write:\\n\\nfrom huggingface_hub import login login()\\n\\nThe code above will ask you to enter an access token:\\n\\nA successful login should look like this (pay attention to the permissions):\\n\\nThen, you can use the trainer\\'s push_to_hub() method to upload everything to your account in the Hub. The model will be named after the output_dir argument of the training arguments:\\n\\ntrainer.push_to_hub()\\n\\nThere you go! Our model is out there in the world, and anyone can use it to translate English into Yoda speak.\\n\\nThat\\'s a wrap!\\n\\nDid you like this post?

You can think of this initial chapter as a recipe you can just follow. It\\'s a \"shoot first, ask questions later\" kind of post.\\n\\nYou\\'ll learn how to:\\n\\nLoad a quantized model using BitsAndBytes\\n\\nConfigure low-rank adapters (LoRA) using Hugging Face\\'s peft\\n\\nLoad and format a dataset\\n\\nFine-tune the model using the supervised fine-tuning trainer (SFTTrainer) from Hugging Face\\'s trl\\n\\nUse the fine-tuned model to generate a sentence\\n\\nJupyter Notebook\\n\\nThe Jupyter notebook corresponding to this post is part of the official Fine-Tuning LLMs repository on GitHub. You can also run it directly in Google Colab\\n\\nSetup\\n\\nIf you\\'re running it on Colab, you\\'ll need to pip install a few libraries: datasets, bitsandbytes, and trl.\\n\\nFor better reproducibility during training, however, use the pinned versions instead:\\n\\n#!pip install datasets bitsandbytes trl !pip install transformers==4.55.2 peft==0.17.0 accelerate==1.10.0 trl==0.21.0 bitsandbytes==0.47.0 datasets==4.0.0 huggingface-hub==0.34.4 safetensors==0.6.2 pandas==2.2.2 matplotlib==3.10.0 numpy==2.0.2\\n\\nImports\\n\\nFor the sake of organization, all libraries needed throughout the code used are imported at its very start. For this post, we\\'ll need the following imports:\\n\\nimport os import torch from datasets import load_dataset from peft import get_peft_model, LoraConfig, prepare_model_for_kbit_training from transformers import AutoModelForCausalLM, AutoTokenizer, BitsAndBytesConfig from trl import SFTConfig, SFTTrainer\\n\\nLoading a Quantized Base Model\\n\\nWe start by loading a quantized model, so it takes up less space in the GPU\\'s RAM. A quantized model replaces the original weights with approximate values that are represented by fewer bits. The simplest and most straightforward way to quantize a model is to turn its weights from 32-bit floating-point (FP32) numbers into 4-bit floating-point numbers (NF4). This simple yet powerful change already reduces the model\\'s memory footprint by roughly a factor of eight.\\n\\nWe can use an instance of BitsAndBytesConfig as the quantization_config argument while loading a model using the from_pretrained() method. To keep it flexible, so you can try it out with any other model of your choice, we\\'re using Hugging Face\\'s AutoModelForCausalLM. The repo you choose to use determines the model being loaded.\\n\\nWithout further ado, here\\'s our quantized model being loaded:\\n\\nbnb_config = BitsAndBytesConfig( load_in_4bit=True, bnb_4bit_quant_type=\"nf4\", bnb_4bit_use_double_quant=True, bnb_4bit_compute_dtype=torch.float32 ) repo_id = \\'microsoft/Phi-3-mini-4k-instruct\\' model = AutoModelForCausalLM.from_pretrained( repo_id, device_map=\"cuda:0\", quantization_config=bnb_config )\\n\\n\"The Phi-3-Mini-4K-Instruct is a 3.8B parameters, lightweight, state-of-the-art open model trained with the Phi-3 datasets that includes both synthetic data and the filtered publicly available websites data with a focus on high-quality and reasoning dense properties. The model belongs to the Phi-3 family with the Mini version in two variants 4K and 128K which is the context length (in tokens) that it can support.\" Source: Hugging Face Hub\\n\\nOnce the model is loaded, you can see how much space it occupies in memory using the get_memory_footprint() method.\\n\\nprint(model.get_memory_footprint()/1e6)\\n\\n2206.347264\\n\\nEven though it\\'s been quantized, the model still takes up a bit more than 2 gigabytes of RAM. The quantization procedure focuses on the linear layers within the Transformer decoder blocks (also referred to as \"layers\" in some cases):\\n\\nmodel\\n\\nPhi3ForCausalLM( (model): Phi3Model( (embed_tokens): Embedding(32064, 3072, padding_idx=32000) (embed_dropout): Dropout(p=0.0, inplace=False) (layers): ModuleList( (0-31): 32 x Phi3DecoderLayer( (self_attn): Phi3Attention( (o_proj): Linear4bit(in_features=3072, out_features=3072, bias=False) <1> (qkv_proj): Linear4bit(in_features=3072, out_features=9216, bias=False) <1> (rotary_emb): Phi3RotaryEmbedding() ) (mlp): Phi3MLP( (gate_up_proj): Linear4bit(in_features=3072, out_features=16384, bias=False) <1> (down_proj): Linear4bit(in_features=8192, out_features=3072, bias=False) <1> (activation_fn): SiLU() ) (input_layernorm): Phi3RMSNorm((3072,), eps=1e-05) (resid_attn_dropout): Dropout(p=0.0, inplace=False) (resid_mlp_dropout): Dropout(p=0.0, inplace=False) (post_attention_layernorm): Phi3RMSNorm((3072,), eps=1e-05) ) ) (norm): Phi3RMSNorm((3072,), eps=1e-05) ) (lm_head): Linear(in_features=3072, out_features=32064, bias=False) )\\n\\n<1> Quantized layers\\n\\nA quantized model can be used directly for inference, but it cannot be trained any further. Those pesky Linear4bit layers take up much less space, which is the whole point of quantization; however, we cannot update them.\\n\\nWe need to add something else to our mix, a sprinkle of adapters.\\n\\nSetting Up Low-Rank Adapters (LoRA)\\n\\nLow-rank adapters can be attached to each and every one of the quantized layers. The adapters are mostly regular Linear layers that can be easily updated as usual. The clever trick in this case is that these adapters are significantly smaller than the layers that have been quantized.\\n\\nSince the quantized layers are frozen (they cannot be updated), setting up LoRA adapters on a quantized model drastically reduces the total number of trainable parameters to just 1% (or less) of its original size.\\n\\nWe can set up LoRA adapters in three easy steps:\\n\\nCall prepare_model_for_kbit_training() to improve numerical stability during training.\\n\\nCreate an instance of LoraConfig.\\n\\nApply the configuration to the quantized base model using the get_peft_model() method.\\n\\nLet\\'s try it out with our model:\\n\\nmodel = prepare_model_for_kbit_training(model) config = LoraConfig( # the rank of the adapter, the lower the fewer parameters you\\'ll need to train r=8, lora_alpha=16, # multiplier, usually 2*r bias=\"none\", lora_dropout=0.05, task_type=\"CAUSAL_LM\", # Newer models, such as Phi-3 at time of writing, may require # manually setting target modules target_modules=[\\'o_proj\\', \\'qkv_proj\\', \\'gate_up_proj\\', \\'down_proj\\'], ) model = get_peft_model(model, config) model\\n\\nPeftModelForCausalLM( (base_model): LoraModel( (model): Phi3ForCausalLM( (model): Phi3Model( (embed_tokens): Embedding(32064, 3072, padding_idx=32000) (embed_dropout): Dropout(p=0.0, inplace=False) (layers): ModuleList( (0-31): 32 x Phi3DecoderLayer( (self_attn): Phi3Attention( (o_proj): lora.Linear4bit( <1> (base_layer): Linear4bit(in_features=3072, out_features=3072, bias=False) (lora_dropout): ModuleDict((default): Dropout(p=0.05, inplace=False)) (lora_A): ModuleDict( (default): Linear(in_features=3072, out_features=8, bias=False) ) (lora_B): ModuleDict( (default): Linear(in_features=8, out_features=3072, bias=False) ) (lora_embedding_A): ParameterDict() (lora_embedding_B): ParameterDict() (lora_magnitude_vector): ModuleDict() ) (qkv_proj): lora.Linear4bit(...) <1> (rotary_emb): Phi3RotaryEmbedding() ) (mlp): Phi3MLP( (gate_up_proj): lora.Linear4bit(...) <1> (down_proj): lora.Linear4bit(...) <1> (activation_fn): SiLU() ) (input_layernorm): Phi3RMSNorm((3072,), eps=1e-05) (resid_attn_dropout): Dropout(p=0.0, inplace=False) (resid_mlp_dropout): Dropout(p=0.0, inplace=False) (post_attention_layernorm): Phi3RMSNorm((3072,), eps=1e-05) ) ) (norm): Phi3RMSNorm((3072,), eps=1e-05) ) (lm_head): Linear(in_features=3072, out_features=32064, bias=False) ) ) )\\n\\n<1> LoRA adapters\\n\\nThe output of the other three LoRA layers (qkv_proj, gate_up_proj, and down_proj) was suppressed to shorten the output.\\n\\nDid you get the following error? ValueError: Please specify `target_modules` in `peft_config` Most likely, you don\\'t need to specify the target_modules if you\\'re using one of the well-known models. The peft library takes care of it by automatically choosing the appropriate targets. However, there may be a gap between the time a popular model is released and the time the library gets updated. So, if you get the error above, look for the quantized layers in your model and list their names in the target_modules argument.\\n\\nThe quantized layers (Linear4bit) have turned into lora.Linear4bit modules where the quantized layer itself became the base_layer with some regular Linear layers (lora_A and lora_B) added to the mix.\\n\\nThese extra layers would make the model only slightly larger. However, the model preparation function (prepare_model_for_kbit_training()) turned every non-quantized layer to full precision (FP32), thus resulting in a 30% larger model:\\n\\nprint(model.get_memory_footprint()/1e6)\\n\\n2651.080704\\n\\nSince most parameters are frozen, only a tiny fraction of the total number of parameters are currently trainable, thanks to LoRA!\\n\\ntrain_p, tot_p = model.get_nb_trainable_parameters() print(f\\'Trainable parameters: {train_p/1e6:.2f}M\\') print(f\\'Total parameters: {tot_p/1e6:.2f}M\\') print(f\\'% of trainable parameters: {100*train_p/tot_p:.2f}%\\')\\n\\nTrainable parameters: 12.58M Total parameters: 3833.66M % of trainable parameters: 0.33%\\n\\nThe model is ready to be fine-tuned, but we are still missing one key component: our dataset.\\n\\nFormatting Your Dataset\\n\\n\"Like Yoda, speak, you must. Hrmmm.\" Master Yoda\\n\\nThe dataset yoda_sentences consists of 720 sentences translated from English to Yoda-speak. The dataset is hosted on the Hugging Face Hub and we can easily load it using the load_dataset() method from the Hugging Face datasets library:\\n\\ndataset = load_dataset(\"dvgodoy/yoda_sentences\", split=\"train\") dataset\\n\\nDataset({ features: [\\'sentence\\', \\'translation\\', \\'translation_extra\\'], num_rows: 720 })\\n\\nThe dataset has three columns:\\n\\noriginal English sentence (sentence)\\n\\nbasic translation to Yoda-speak (translation)\\n\\nenhanced translation including typical Yesss and Hrrmm interjections (translation_extra)\\n\\ndataset[0]\\n\\n{\\'sentence\\': \\'The birch canoe slid on the smooth planks.\\', \\'translation\\': \\'On the smooth planks, the birch canoe slid.\\', \\'translation_extra\\': \\'On the smooth planks, the birch canoe slid. Yes, hrrrm.\\'}\\n\\nThe SFTTrainer we\\'ll be using to fine-tune the model can automatically handle datasets in conversational format.\\n\\n{\"messages\":[ {\"role\": \"system\", \"content\": \"\"}, {\"role\": \"user\", \"content\": \"\"}, {\"role\": \"assistant\", \"content\": \"\"} ]}\\n\\nIMPORTANT UPDATE: unfortunately, in more recent versions of the trl library, the \"instruction\" format is not properly supported anymore, thus leading to the chat template not being applied to the dataset. In order to avoid this issue, we can convert the dataset to the \"conversational\" format.\\n\\nSo, we\\'ll convert the dataset to the conversational format using the format_dataset() function below:\\n\\n# Adapted from trl.extras.dataset_formatting.instructions_formatting_function # Converts dataset from prompt/completion format (not supported anymore) # to the conversational format def format_dataset(examples): if isinstance(examples[\"prompt\"], list): output_texts = [] for i in range(len(examples[\"prompt\"])): converted_sample = [ {\"role\": \"user\", \"content\": examples[\"prompt\"][i]}, {\"role\": \"assistant\", \"content\": examples[\"completion\"][i]}, ] output_texts.append(converted_sample) return {\\'messages\\': output_texts} else: converted_sample = [ {\"role\": \"user\", \"content\": examples[\"prompt\"]}, {\"role\": \"assistant\", \"content\": examples[\"completion\"]}, ] return {\\'messages\\': converted_sample}\\n\\ndataset = dataset.rename_column(\"sentence\", \"prompt\") dataset = dataset.rename_column(\"translation_extra\", \"completion\") dataset = dataset.map(format_dataset) dataset = dataset.remove_columns([\\'prompt\\', \\'completion\\', \\'translation\\']) messages = dataset[0][\\'messages\\'] messages\\n\\n[{\\'role\\': \\'user\\', \\'content\\': \\'The birch canoe slid on the smooth planks.\\'}, {\\'role\\': \\'assistant\\', \\'content\\': \\'On the smooth planks, the birch canoe slid. Yes, hrrrm.\\'}]\\n\\nTokenizer\\n\\nBefore moving into the actual training, we still need to load the tokenizer that corresponds to our model. The tokenizer is an important part of this process, determining how to convert text into tokens in the same way used to train the model.\\n\\nFor instruction/chat models, the tokenizer also contains its corresponding chat template that specifies:\\n\\nWhich special tokens should be used, and where they should be placed.\\n\\nWhere the system directives, user prompt, and model response should be placed.\\n\\nWhat is the generation prompt, that is, the special token that triggers the model\\'s response (more on that in the \"Querying the Model\" section)\\n\\nIMPORTANT UPDATE: due to changes in the default collator used by the SFTTrainer class while building the dataset, the EOS token (which is, in Phi-3, the same as the PAD token) was masked in the labels too thus leading to the model not being able to properly stop token generation.\\n\\nIn order to address this change, we can assign the UNK token to the PAD token, so the EOS token becomes unique and therefore not masked as part of the labels.\\n\\ntokenizer = AutoTokenizer.from_pretrained(repo_id) tokenizer.pad_token = tokenizer.unk_token tokenizer.pad_token_id = tokenizer.unk_token_id tokenizer.chat_template\\n\\n\"{% for message in messages %} {% if message[\\'role\\'] ## \\'system\\' %} {{\\'<|system|>\\\\n\\' + message[\\'content\\'] + \\'<|end|>\\\\n\\'}} {% elif message[\\'role\\'] ## \\'user\\' %} {{\\'<|user|>\\\\n\\' + message[\\'content\\'] + \\'<|end|>\\\\n\\'}} {% elif message[\\'role\\'] ## \\'assistant\\' %} {{\\'<|assistant|>\\\\n\\' + message[\\'content\\'] + \\'<|end|>\\\\n\\'}} {% endif %} {% endfor %} {% if add_generation_prompt %} {{ \\'<|assistant|>\\\\n\\' }}{% else %}{{ eos_token }} {% endif %}\"\\n\\nNever mind the seemingly overcomplicated template (I have added line breaks and indentation to it so it\\'s easier to read). It simply organizes the messages into a coherent block with the appropriate tags, as shown below (tokenize=False ensures we get readable text back instead of a numeric sequence of token IDs):\\n\\nprint(tokenizer.apply_chat_template(messages, tokenize=False))\\n\\n<|user|> The birch canoe slid on the smooth planks.<|end|> <|assistant|> On the smooth planks, the birch canoe slid. Yes, hrrrm.<|end|> <|endoftext|>\\n\\nNotice that each interaction is wrapped in either <|user|> or <|assistant|> tokens at the beginning and <|end|> at the end. Moreover, the <|endoftext|> token indicates the end of the whole block.\\n\\nDifferent models will have different templates and tokens to indicate the beginning and end of sentences and blocks.\\n\\nWe\\'re now ready to tackle the actual fine-tuning!\\n\\nFine-Tuning with SFTTrainer\\n\\nFine-tuning a model, whether large or otherwise, follows exactly the same training procedure as training a model from scratch. We could write our own training loop in pure PyTorch, or we could use Hugging Face\\'s Trainer to fine-tune our model.\\n\\nIt is much easier, however, to use SFTTrainer instead (which uses Trainer underneath, by the way), since it takes care of most of the nitty-gritty details for us, as long as we provide it with the following four arguments:\\n\\na model\\n\\na tokenizer\\n\\na dataset\\n\\na configuration object\\n\\nWe\\'ve already got the first three elements; let\\'s work on the last one.\\n\\nSFTConfig\\n\\nThere are many parameters that we can set in the configuration object. We have divided them into four groups:\\n\\nMemory usage optimization parameters related to gradient accumulation and checkpointing\\n\\nDataset-related arguments, such as the max_seq_length required by your data, and whether you are packing or not the sequences\\n\\nTypical training parameters such as the learning_rate and the num_train_epochs\\n\\nEnvironment and logging parameters such as output_dir (this will be the name of the model if you choose to push it to the Hugging Face Hub once it\\'s trained), logging_dir, and logging_steps.\\n\\nWhile the learning rate is a very important parameter (as a starting point, you can try the learning rate used to train the base model in the first place), it\\'s actually the maximum sequence length that\\'s more likely to cause out-of-memory issues.\\n\\nMake sure to always pick the shortest possible max_seq_length that makes sense for your use case. In ours, the sentences—both in English and Yoda-speak—are quite short, and a sequence of 64 tokens is more than enough to cover the prompt, the completion, and the added special tokens.\\n\\nFlash attention (which, unfortunately, isn\\'t supported in Colab), allows for more flexibility in working with longer sequences, avoiding the potential issue of OOM errors.\\n\\nIMPORTANT UPDATE: The release of trl version 0.20 brought several changes to the SFTConfig:\\n\\npacking is performed differently than it was, unless packing_strategy=\\'wrapped\\' is set;\\n\\nthe max_seq_length argument was renamed to max_length;\\n\\nthe bf16 defaults to True but, at the time of this update (Aug/2025), it didn\\'t check if the BF16 type was actually available or not, so it\\'s included in the configuration now.\\n\\nsft_config = SFTConfig( ## GROUP 1: Memory usage # These arguments will squeeze the most out of your GPU\\'s RAM # Checkpointing gradient_checkpointing=True, # this saves a LOT of memory # Set this to avoid exceptions in newer versions of PyTorch gradient_checkpointing_kwargs={\\'use_reentrant\\': False}, # Gradient Accumulation / Batch size # Actual batch (for updating) is same (1x) as micro-batch size gradient_accumulation_steps=1, # The initial (micro) batch size to start off with per_device_train_batch_size=16, # If batch size would cause OOM, halves its size until it works auto_find_batch_size=True, ## GROUP 2: Dataset-related max_length=64, # renamed in v0.20 # Dataset # packing a dataset means no padding is needed packing=True, packing_strategy=\\'wrapped\\', # added to approximate original packing behavior ## GROUP 3: These are typical training parameters num_train_epochs=10, learning_rate=3e-4, # Optimizer # 8-bit Adam optimizer - doesn\\'t help much if you\\'re using LoRA! optim=\\'paged_adamw_8bit\\', ## GROUP 4: Logging parameters logging_steps=10, logging_dir=\\'./logs\\', output_dir=\\'./phi3-mini-yoda-adapter\\', report_to=\\'none\\'. # ensures bf16 (the new default) is only used when it is actually available bf16=torch.cuda.is_bf16_supported(including_emulation=False) )\\n\\nSFTTrainer\\n\\n\"It is training time!\" The Hulk\\n\\nIMPORTANT UPDATE: The current version of trl (0.21) has a known issue where training fails if the LoRA configuration has already been applied to the model, as the trainer freezes the whole model, including the adapters.\\n\\nHowever, it works as expected when the configuration is passed as the peft_config argument to the trainer, since it is applied after freezing the existing layers.\\n\\nIf the model already contains the adapters, as in our case, training still works, but we need to use the underlying original model instead (model.base_model.model) to ensure the save_model() method functions correctly.\\n\\nWe can now finally create an instance of the supervised fine-tuning trainer:\\n\\ntrainer = SFTTrainer( model=model.base_model.model, # the underlying Phi-3 model peft_config=config, # added to fix issue in TRL>=0.20 processing_class=tokenizer, args=sft_config, train_dataset=dataset, )\\n\\nThe SFTTrainer had already preprocessed our dataset, so we can take a look inside and see how each mini-batch was assembled:\\n\\ndl = trainer.get_train_dataloader() batch = next(iter(dl))\\n\\nLet\\'s check the labels; after all, we didn\\'t provide any, did we?\\n\\nbatch[\\'input_ids\\'][0], batch[\\'labels\\'][0]\\n\\n(tensor([ 1746, 29892, 278, 10435, 3147, 698, 287, 29889, 32007, 32000, 32000, 32010, 10987, 278, 3252, 262, 1058, 380, 1772, 278, 282, 799, 29880, 18873, 1265, 29889, 32007, 32001, 11644, 380, 1772, 278, 282, 799, 29880, 18873, 1265, 29892, 1284, 278, 3252, 262, 29892, 366, 1818, 29889, 3869, 29892, 298, 21478, 1758, 29889, 32007, 32000, 32000, 32010, 315, 329, 278, 13793, 393, 7868, 29879, 278], device=\\'cuda:0\\'), tensor([ 1746, 29892, 278, 10435, 3147, 698, 287, 29889, 32007, 32000, 32000, 32010, 10987, 278, 3252, 262, 1058, 380, 1772, 278, 282, 799, 29880, 18873, 1265, 29889, 32007, 32001, 11644, 380, 1772, 278, 282, 799, 29880, 18873, 1265, 29892, 1284, 278, 3252, 262, 29892, 366, 1818, 29889, 3869, 29892, 298, 21478, 1758, 29889, 32007, 32000, 32000, 32010, 315, 329, 278, 13793, 393, 7868, 29879, 278], device=\\'cuda:0\\'))\\n\\nThe labels were added automatically, and they\\'re exactly the same as the inputs.

We need to build a list of \"messages\"—ours, from the user, in this case—and prompt the model to answer by indicating it\\'s its turn to write.\\n\\nThis is the purpose of the add_generation_prompt argument: it adds <|assistant|> to the end of the conversation, so the model can predict the next word—and continue doing so until it predicts an <|endoftext|> token.\\n\\nThe helper function below assembles a message (in the conversational format) and applies the chat template to it, appending the generation prompt to its end.\\n\\ndef gen_prompt(tokenizer, sentence): converted_sample = [{\"role\": \"user\", \"content\": sentence}] prompt = tokenizer.apply_chat_template( converted_sample, tokenize=False, add_generation_prompt=True ) return prompt\\n\\nLet\\'s try generating a prompt for an example sentence:\\n\\nsentence = \\'The Force is strong in you!\\' prompt = gen_prompt(tokenizer, sentence) print(prompt)\\n\\n<|user|> The Force is strong in you!<|end|> <|assistant|>\\n\\nThe prompt seems about right; let\\'s use it to generate a completion. The helper function below does the following:\\n\\nIt tokenizes the prompt into a tensor of token IDs (add_special_tokens is set to False because the tokens were already added by the chat template).\\n\\nIt sets the model to evaluation mode.\\n\\nIt calls the model\\'s generate() method to produce the output (generated token IDs).\\n\\nIf the model was trained using mixed-precision, we wrap the generation in the autocast() context manager, which automatically handles conversion between data types.\\n\\nIt decodes the generated token IDs back into readable text.\\n\\ndef generate(model, tokenizer, prompt, max_new_tokens=64, skip_special_tokens=False): tokenized_input = tokenizer( prompt, add_special_tokens=False, return_tensors=\"pt\" ).to(model.device) model.eval() # if it was trained using mixed precision, uses autocast context ctx = torch.autocast(device_type=model.device.type, dtype=model.dtype) \\\\ if model.dtype in [torch.float16, torch.bfloat16] else nullcontext() with ctx: gen_output = model.generate(**tokenized_input, eos_token_id=tokenizer.eos_token_id, max_new_tokens=max_new_tokens) output = tokenizer.batch_decode(gen_output, skip_special_tokens=skip_special_tokens) return output[0]\\n\\nNow, we can finally try out our model and see if it\\'s indeed capable of generating Yoda-speak.\\n\\nprint(generate(model, tokenizer, prompt))\\n\\n<|user|> The Force is strong in you!<|end|><|assistant|> Strong in you, the Force is. Yes, hrrmmm.<|end|>\\n\\nAwesome! It works! Like Yoda, the model speaks. Hrrrmm.\\n\\nCongratulations, you\\'ve fine-tuned your first LLM!\\n\\nNow, you\\'ve got a small adapter that can be loaded into an instance of the Phi-3 Mini 4K Instruct model to turn it into a Yoda translator! How cool is that?\\n\\nSaving the Adapter\\n\\nOnce the training is completed, you can save the adapter (and the tokenizer) to disk by calling the trainer\\'s save_model() method. It will save everything to the specified folder:\\n\\ntrainer.save_model(\\'local-phi3-mini-yoda-adapter\\')\\n\\nThe files that were saved include:\\n\\nthe adapter configuration (adapter_config.json) and weights (adapter_model.safetensors)—the adapter itself is just 50 MB in size\\n\\nthe training arguments (training_args.bin)\\n\\nthe tokenizer (tokenizer.json and tokenizer.model), its configuration (tokenizer_config.json), and its special tokens (added_tokens.json and speciak_tokens_map.json)\\n\\na README file\\n\\nIf you\\'d like to share your adapter with everyone, you can also push it to the Hugging Face Hub. First, log in using a token that has permission to write:\\n\\nfrom huggingface_hub import login login()\\n\\nThe code above will ask you to enter an access token:\\n\\nA successful login should look like this (pay attention to the permissions):\\n\\nThen, you can use the trainer\\'s push_to_hub() method to upload everything to your account in the Hub. The model will be named after the output_dir argument of the training arguments:\\n\\ntrainer.push_to_hub()\\n\\nThere you go!

It directly regresses the velocity field of an ordinary differential equation (ODE), enabling simulation-free learning of the generative process.

(b) plots the mean squared error between the predicted and actual noisy image across sampling steps.\\n\\nResolution-Dependent Misalignment. While minor for- ward–reverse discrepancies are expected due to training lim- itations and imperfect regression of the velocity field, we observe that these inconsistencies vary systematically with resolution. In particular, the misalignment becomes substan- tially worse when sampling at resolutions that deviate from the model’s training resolution.\\n\\nTo understand this phenomenon, we compare the outputs of the forward noise process across different resolutions using the same noise level σt. As shown in Figure 1(a), more signal is destroyed in the low-resolution images in this forward process compared to the high-resolution ones, despite the shared diffusion schedule {σt}. This suggests that the perceptual impact of noise is resolution-dependent.\\n\\nWe hypothesize that this effect arises from spatial com- pression. In low-resolution images, each pixel encodes a larger region of semantic content, so adding noise dispro- portionately disrupts meaningful structure. In contrast, high- resolution images have greater spatial redundancy, which makes the same level of noise less perceptually destructive.

Besides cropping artifacts likely caused by positional encodings, generated images often exhibit structural glitches and texture breakdowns (top). Our method (bottom) improves visual fidelity by calibrating the conditioning noise level without retraining or architectural changes.\\n\\n(b) MSE between forward and reverse trajectories across timesteps t at different resolutions. Misalign- ment increases with resolution shift, especially at early steps.\\n\\nFigure 2. Training-testing misalignment in diffusion sampling. The forward (noise addition) and reverse (denoising) processes are theoretically symmetric but diverge during test-time sampling. (a) illustrates the conceptual discrepancy. (b) plots the mean squared error between the predicted and actual noisy image across sampling steps.\\n\\nResolution-Dependent Misalignment. While minor for- ward–reverse discrepancies are expected due to training lim- itations and imperfect regression of the velocity field, we observe that these inconsistencies vary systematically with resolution. In particular, the misalignment becomes substan- tially worse when sampling at resolutions that deviate from the model’s training resolution.\\n\\nTo understand this phenomenon, we compare the outputs of the forward noise process across different resolutions using the same noise level σt. As shown in Figure 1(a), more signal is destroyed in the low-resolution images in this forward process compared to the high-resolution ones, despite the shared diffusion schedule {σt}. This suggests that the perceptual impact of noise is resolution-dependent.\\n\\nWe hypothesize that this effect arises from spatial com- pression. In low-resolution images, each pixel encodes a larger region of semantic content, so adding noise dispro- portionately disrupts meaningful structure. In contrast, high- resolution images have greater spatial redundancy, which makes the same level of noise less perceptually destructive. As a result, a fixed σt induces qualitatively different levels of corruption depending on resolution.\\n\\nTo quantify this, we analyze SSIM between clean images x0 and their forward-noised counterparts xt across multi- ple resolutions. Figure 1(b) shows that SSIM consistently degrades more rapidly at lower resolutions.

Resolution-Aware Test-Time Calibration\\n\\nWhile recent methods have extended diffusion models to ar- bitrary resolutions by adapting token lengths or position en- codings [28], we focus instead on correcting forward-reverse misalignment through test-time adjustment of the condition- ing noise level. Rather than modifying the sampling tra- jectory or retraining the model, we propose a lightweight post-processing procedure that adjusts only the input noise level ˆσt passed to the denoiser at each timestep.\\n\\nRole of Noise-Level Embedding. At each timestep, diffu- sion models receive not only the noisy latent xt but also a noise-level or timestep embedding that encodes the expected magnitude of corruption in the input. This embedding allows the model to adapt its prediction of the denoised image based on how noisy the input is: for low noise, the model performs minor corrections, whereas for high noise, it applies stronger denoising. In our framework, the conditioning noise ˆσt is directly mapped to this embedding. Consequently, by ma- nipulating ˆσt at test time, we can explicitly interfere how the model interprets the noise level in the input, enabling a resolution-aware correction without changing the learned weights or the sampling schedule.\\n\\nProblem Setup. Let ϕ denote a trained flow-matching diffusion model with a predefined noise schedule σtt = 0T. At each timestep t, the model receives a noisy latent xt+1 and a noise-level embedding derived from a conditioning noise ˆσt. This embedding informs the network how much noise to expect and guides its prediction of the velocity field ϕ(xt+1, ˆσt).\\n\\nIn standard sampling, ˆσt = σt follows the original noise schedule. In our approach, we allow ˆσt to differ from σt to correct forward–reverse misalignment at test time. By tuning ˆσt, we can adapt the model’s denoising behavior to different resolutions without changing the learned weights or sampling procedure.\\n\\nGiven a noisy latent input xt+1, we expect xt to match the forward sample obtained by applying Gaussian noise to a clean latent x0. Our goal is to find a conditioning noise level ˆσt such that the denoised prediction ˆxt minimizes the discrepancy from xt:\\n\\nCoarse-to-Fine Search Strategy. We estimate ˆσ∗ t via a coarse-to-fine grid search that minimizes the one-step reverse error at each timestep. Starting from the final step t = T−1, we proceed backward in time.

These results suggest that NoiseShift comple- ments, but does not replace, the resolution-aware scheduling baked into the model itself.\\n\\n5.4. Ablation Studies\\n\\nThis section studies the number of samples used in the Noise- Shift calibration. As shown in Figure 5, even though the number of samples varies from 50 to 200, the calibrated sigmas always converge in almost the same range. Given the fact that the calibration already has a very low computation cost, reducing the number of samples can lead to an almost free re-calibration, which improves the low-resolution image generation quality.\\n\\n5.5. Qualitative Results\\n\\nIn Figure 7 and Figure 6, we present qualitative examples of SD3 and SD3.5 [9] before and after applying NoiseShift on CelebA and LAION-COCO. Across all resolutions, Noise- Shift improves the overall image quality, providing better structure and textures of the generated images. In Figure 3, we show how NoiseShift improves the Flux-Dev model down to 64×64 resolutions. Overall, we observe the quality im- provement and fewer artifacts across the resolutions.\\n\\n6. Conclusion\\n\\nWe identify resolution-dependent exposure bias as a key contributor to quality degradation in state-of-the-art diffusion models when sampling at lower resolutions. To address this, we introduced NoiseShift, a simple, training-free approach that recalibrates the denoising conditioning to better align with resolution-specific noise distributions. Our method consistently improves image quality across resolutions and is complementary to both noise schedule modifications and architectural enhancements, making it readily applicable to recent advances in text-to-image generation.\\n\\nLimitations and Future Work. While NoiseShift miti- gates exposure bias and enhances cross-resolution perfor- mance, it does not fully solve the challenge of low-resolution generalization. Future work may explore integrating Noise- Shift with learned adapters, dynamic token routing, or resolution-specific fine-tuning strategies.\\n\\nBroader Impact. By enhancing sample quality at low res- olutions, NoiseShift increases the adaptability of text-to- image systems to diverse deployment settings, including mobile and assistive applications. However, the ability to generate increasingly high-quality synthetic content may also exacerbate issues around misinformation and image provenance, highlighting the need for responsible use and effective detection mechanisms.\\n\\nFigure 6.

These properties are especially compelling because their inference requires temporal reasoning and sensitivity to subtle visual cues—such as deformation, deceleration, spreading, or oscillation. By examining how well current video foundation models capture these dynamic attributes, we aim to assess their physical understanding beyond static appearance.\\n\\n*Equal contribution.\\n\\nTo support this investigation, we introduce a new dataset, PhysVid, specifically designed to evaluate the dynamic physical properties from video. Existing datasets lack ground-truth annotations for such properties, so we construct PhysVid using a combination of synthetic videos—rendered via a physics simulator—and real-world videos sourced from the internet or captured in-house. Each video is annotated with physical property values, either derived from simulation parameters or estimated manually. The dataset is designed to facilitate the study of out-of-domain generalization, both within the synthetic domain and from synthetic to real-world data. To establish an upper bound on what is inferable from visual input alone, we implement an oracle method for each property. These oracles leverage privileged access to the visual cues that directly reflect the corresponding property.\\n\\nWe evaluate three categories of video foundation models: generative models, self-supervised mod- els, and multi-modal large language models (MLLMs). For the generative and self-supervised mod- els, we propose a simple yet effective readout mechanism that extracts dynamic physical properties from pre-trained, frozen representations. Our method introduces a learnable query vector that at- tends to internal representation tokens via cross-attention, enabling the selective extraction of rele- vant information. This approach is both lightweight and training-efficient. For MLLMs, we explore various prompting strategies to elicit predictions of dynamic physical properties directly from video input. These strategies include few-shot prompting to provide task context, as well as procedu- ral prompting that guides the model through the oracle estimation steps—helping it focus on the intrinsic visual cues that reveal the target properties.\\n\\n2 RELATED WORK\\n\\nPhysics Prediction from Images and Videos. Inferring physical properties from visual obser- vations remains a core challenge in computer vision. Early methods estimate latent physical pa- rameters (e.g., mass, friction, stiffness) via differentiable physics engines or learning-based simula- tors (Wu et al., 2015; Ding et al., 2021; Jatavallabhula et al., 2021; Li et al., 2020; Wang et al., 2020a; 2018), while later works infer salient attributes like viscosity or elasticity from task-specific visual cues (Kawabe et al., 2014; Paulun et al., 2015; Assen et al., 2018; Norman et al., 2007; Kawabe & Nishida, 2016; Paulun et al., 2017; Paulun & Fleming, 2020), yet both rely heavily on simulation supervision, domain priors, or handcrafted heuristics. More recently, unsupervised learning of intu- itive physics has emerged via next-frame prediction from large-scale everyday physical scenes (Vo- leti et al., 2022; Lu et al., 2023; Agrawal et al., 2016; Finn & Levine, 2017; Babaeizadeh et al., 2021; Hafner et al., 2019; Fragkiadaki et al., 2016; Garcia et al., 2025), capturing latent dynamics without explicit physical supervision. However, the resulting representations are usually implicit and lack interpretability in terms of concrete physical quantities.

Since it is challenging to find real-world videos online that provide ground- truth viscosity values while controlling for other relevant physical parameters—such as ρ, D and v, we collected real videos under controlled conditions. We use a funnel with a fixed nozzle diameter to produce a consistent liquid column. A funnel holder allows us to fix the height from which the liquid is poured, thereby controlling the initial velocity v.

We therefore collect a real video dataset featuring 5 differ- ent objects and 6 surface materials, spanning a wide range of dynamic friction values. Each object is given an initial velocity by sliding it down from a slope and it then slides on a horizontal plane. To obtain ground-truth friction coefficients, we use a spring dynamometer to measure the friction force F for each object-surface pair (by dragging the object at constant speed), and record the object’s weight G. The dynamic friction coefficient is then computed as: µk = F/G.\\n\\n4 INFERRING PHYSICAL PROPERTIES\\n\\nThis section presents the three different ways for inferring dynamic physical properties: an oracle method via classical computer vision techniques (Section 4.1); a visual prompt mechanism for video generative and self-supervised models (Section 4.2); and prompts for MLLMs (Section 4.3).\\n\\n4.1 ORACLE ESTIMATION\\n\\nElasticity. We aim to estimate elasticity from both synthetic and real-world videos. The key visual cue is the relative height of the ball during its drop and subsequent bounce, observed in 3D. As noted earlier, the ratio in 3D can be approximated from their corresponding image-space measurements. This approximation is exact when the motion occurs in a fronto-parallel plane, and remains reason- ably accurate otherwise—since the ratio of lengths between parallel line segments is invariant under affine transformations (Hartley & Zisserman, 2004). Given that perspective effects are minimal in our videos, the affine approximation provides a reliable estimate for elasticity. To automate this process, we extract the ball’s trajectory y(t) from the video and input the sequence of ratios into a GRU network to regress the elasticity. In detail, we segment the ball in each frame and use their centroids as the y-coordinate. From this trajectory, we identify key points: the initial drop position, the first ground contact, and the peak of the first bounce. The resulting trajectory is normalized to the range [0,1], by subtracting the y-coordinate of the first ground contact and dividing by the initial drop height. This normalization not only ensures invariance to viewpoint and scale, but also sim-\\n\\nViscosity\\n\\nWe study the viscosity by observing a liquid column dropping and spreading on the ground.

The objective in each case is to extract a measurement from the sequence that can directly be used to predict the property. For elasticity, we extract the centroid trajectory from segmentation masks, and then normalize the y-coordinates into 0-1; the ratio of bouncing to dropping height over the sequence indicates the elasticity. For viscosity, we calculate the area size in the image via segmentation masks, and then normalize the area sizes by the area in the frame when the liquid first touches the ground; the slope of the normalized area size sequence reflects the viscosity. For friction, we transform to a bird’s eye view (using a homography transformation based on 4 corner points of the top surface of the sliding object), and fit a parabola x = αt2 + βt + c to the transformed trajectory; the parabola coefficient α predicts the friction coefficient.

We train a GRU, as it is noisy to directly obtain hdrop and hbounce using heuristics (e.g., determining the maximum and minimum points), and in practice a GRU provides a good estimate.

The key visual cue for estimating viscosity is the rate at which the liquid spreads on the ground-plane, measured as an area ratio normalized by the initial area of the liquid column. As with elasticity, we approximate perspective using an affine transformation – here of the ground- plane. Since area ratios are invariant under affine transformations (Hartley & Zisserman, 2004), the liquid’s normalized image-space area growth approximates its true normalized ground-plane expansion (in our setup the liquid spreads only within a limited area around the release point, and the camera is distant; consequently an affine viewing approximation is adequate). Specifically, we extract segmentation masks for each frame and compute the liquid’s area over time. This area sequence is normalized by the area in the first frame where the liquid contacts the surface, ensuring invariance to viewpoint and scale. The process is illustrated in Figure 2 (middle row). For absolute prediction, we calculate the slope k of A(t) and use 1/k to represent the viscosity value; For relative comparison, the binary decision score between two videos v1 and v2 is calculated as in Equation 1, where e1 and e2 are the estimated viscosities based on area growth rate.\\n\\nFriction. The key visual cue for estimating dynamic friction is the acceleration of the sliding ob- ject—i.e., how quickly its velocity decreases due to friction—which can be inferred from its position over time. Since the object moves significantly in the video, we do not use an affine approximation, but instead take account of the projective geometry by mapping the object’s motion to a bird’s-eye view, allowing for consistent trajectory analysis. This is achieved by estimating a homography be- tween the image and bird’s eye view (normal to the plane) from the four corners of the object’s top surface (see Figure 2, bottom row). We fit a parabola x = αt2 + βt + c to the transformed top surface trajectory to estimate the acceleration a from the coefficient α, and the coefficient of friction µk = 2α/g. For absolute prediction, we use the estimated µk to represent the friction coefficient value; For relative comparison, the binary decision score between two videos v1 and v2 is calculated as in Equation 1, where e1 and e2 are the estimated friction coefficients based on the transformed object trajectory.\\n\\n(1)\\n\\n4.2 VIDEO GENERATIVE AND SELF-SUPERVISED MODELS\\n\\nVideo Feature Extraction\\n\\nFigure 2: Oracle methods for physical properties.

Since the object moves significantly in the video, we do not use an affine approximation, but instead take account of the projective geometry by mapping the object’s motion to a bird’s-eye view, allowing for consistent trajectory analysis. This is achieved by estimating a homography be- tween the image and bird’s eye view (normal to the plane) from the four corners of the object’s top surface (see Figure 2, bottom row). We fit a parabola x = αt2 + βt + c to the transformed top surface trajectory to estimate the acceleration a from the coefficient α, and the coefficient of friction µk = 2α/g. For absolute prediction, we use the estimated µk to represent the friction coefficient value; For relative comparison, the binary decision score between two videos v1 and v2 is calculated as in Equation 1, where e1 and e2 are the estimated friction coefficients based on the transformed object trajectory.\\n\\n(1)\\n\\n4.2 VIDEO GENERATIVE AND SELF-SUPERVISED MODELS\\n\\nVideo Feature Extraction\\n\\nFigure 3: Architectures for dynamic physical property prediction. Left: video generative model as backbone; Middle: video self-supervised model as backbone; Right: multimodal large language model (MLLM). For the pre-trained video diffusion model (U-Net, left) and the pre-trained self- supervised model (ViT, middle), the representations are kept frozen, and a ‘visual prompt’ learns to infer the physical properties. For the MLLMs, the physical properties are inferred using a language prompt (right).\\n\\nGiven a video v ∈ RT×H×W×3, we extract features with a pre-trained video backbone, that can either be generative or self-supervised, resulting into spatiotemporal feature representations, i.e., r = ψ(v) ∈ Rt×h×w×c, which can be detailed as follows.\\n\\nGenerative Model as Backbone. We adopt a pre-trained video diffusion model (Figure left), namely DynamiCrafter (Xing et al to compute the visual features. Specifically, given an input video, we add noise to the latent representations after the pre-trained VAE encoder, and re- place the text prompt with a learnable embedding. We extract multi-scale features from all U-Net layers at diffusion tme 50, Wlll was shown to be effective for capturing 3D physics in prior work ( Tang et al . To aggregate the features, we introduce a learnable query vector ¢, different dimensions of the multi-scale features (see Appendix Setn - r et and then attends to the diffusion tokens (;) via cross-attention: txhxw p= i=1 softmax(q - r;) - r;. The resulting vectors p from different layers are then mapped by another MLP network to a common dimension and average pooled to generate the final video feature representation P. To predict the physical properties, we train the text token of the generative model, together with the ‘visual prompt’ architecture that includes the query ¢ and the MLPs\\n\\nSelf-Supervised Model as Backbone. Here, we adopt a pre-trained self-supervised model (Figure 3, middle), namely V-JEPA-2 (Assran et al., 2025), as the visual backbone. The input video is passed through the model, and we extract feature tokens from all layers of the ViT encoder. Similar to the generative setting, we introduce a learnable query vector q to extract the video feature representation P from the ViT tokens via attentive pooling. Although the feature dimension at each ViT layer is the same, we still use a MLP network to map q to generate the query vector of each layer (keeping it similar to the generative setting in terms of MLP network architecture), and use another MLP network to map the output vectors p to a same dimension as the generative setting before average pooling them to get P. Please see Appendix Section A.2 for more details.\\n\\nPhysical Property Prediction\\n\\nGiven the computed feature P from video foundation models, we train a MLP network to predict the physical properties using the synthetic video dataset training split. The network for each property is trained separately.\\n\\nAbsolute Value Prediction. Given the resulting video feature (P), we pass it through a MLP network γ to predict the absolute value χ of the physical property: χ = γ(P). For elasticity and friction, the absolute value prediction is supervised with L1 loss with the ground truth value; For viscosity, as the ground truth values may have very different scales, i.e., from 1e−5 to 1e−2, the absolute value prediction is trained with Log L1 loss, which calculates L1 loss between the log of the predicted value and the log of the ground truth value.\\n\\nRelative Value Prediction. Given the resulting features for a pair of videos, P1 and P2, we con- catenate them and formulate a binary classification problem, indicating which video has a larger physical property value via a MLP network γ: ξ = γ([P1,P2]). The binary prediction for all three tasks is trained with binary cross entropy loss with the binary ground truth.\\n\\nBridging the Sim2real Gap. Since our models are trained on synthetic datasets, they may not generalize well to real-world test videos due to the domain gap. To mitigate this sim-to-real gap, for both synthetic training and real test, we draw a red circle on each video frame, enclosing the full trajectory of the target object or liquid, as illustrated in Figure 4 (middle). The red circle is obtained\\n\\nFigure 3: Architectures for dynamic physical property prediction.

We explore various prompting strategies on state-of-the- art MLLMs, including Qwen2.5-VL-Max (Hui et al., 2024), GPT-4o (Hurst et al., 2024), and Gem- ini 2.5 Pro (Comanici et al., 2025), as illustrated in Figure 3 (right). Examples of the prompting strategies are provided in Appendix Section E.\\n\\nPreliminary. The MLLM receives video frames as visual input. The text prompt includes (1) a brief description of the target property—for example: “we are studying the viscosity of the liquid, where water is 1.0 and honey is 5000.0.” This is followed by (2) a query, such as: “what is the viscosity value of the liquid in the video?” (absolute) or “which video shows a liquid with higher viscosity? please output a decision score between 0 and 1, indicating the likelihood that the first video exhibits a higher property value.” (relative).

During oracle estimation, we train the GRU network with a learning rate of 1e − 3 and the batch size is 128. For the generative and self-supervised video models, the backbones are frozen, the trainable parameters are optimised with a learning rate of 1e − 5 and the batch size 16. For MLLMs, we perform promp selection, and use the best strategy that we find for each of the absolute and relative settings for the experiments. Few-shot examples and oracle estimation teaching work best for the absolute and relative settings, respectively, as they directly provide the model with more context information about the properties.

Top Left: An example for elasticity absolute value prediction; Bottom Left: An example for friction relative value comparison. For each example, the original input video is shown on the left. A static red circle is overlaid in the center to highlight the full trajectory of the object on every frame, shown in the middle. Model predictions are shown on the right, including results from the Video Generative Model (VGM), Video Self-Supervised Model (VSM), and a MLLM (Gemini in this case). For the relative formulation, the ground truth value of ‘1’ indicates that the first (top) video has larger dynamic friction coefficient than the second video. In this example, the initial velocity of the lego brick in the two videos is similar (note the same displacement from frame 0 to 2), but the velocity reduces to 0 at frame 30 in the first video, while the object is still moving in frame 30 to 60 in the second video. Right: Scatter plots of prediction vs ground truth for the elasticity property from the V-JEPA-2 model.\\n\\n5.1 RESULTS FOR RELATIVE VALUE COMPARISON\\n\\nTable 1 (left) shows relative value comparison results across physical properties and model types. The oracle estimator performs nearly perfectly on test-1 and test-2, and strongly on test-3, indicating that the task is largely solvable using visual cues, geometry, and physics. Both generative and self-supervised video models achieve strong results on synthetic splits (test-1 and test-2). Notably, they can also generalize well to the real-world split (test-3) for viscosity and elastic- ity, which rely on simple height ratios and expansion. However, friction proves more challenging. Models trained on synthetic data struggle to generalize, likely due to the fact that reliance on visual references (e.g., ground plane grids) is absent in real videos, and due to friction’s inherent complex- ity involving higher-order motion and projective geometry of the viewpoint. To further confirm, we introduce an additional real-world training split for friction videos with disjoint objects and surfaces from the test set (see Appendix Section B.2 for more details). Fine-tuning the visual prompting architecture on this data improves performance on the real test split, as shown by the * values in Table 1. Multimodal large language models (MLLMs), though not working very well with Baseline Prompt (see Appendix Section D), when prompted properly, also perform well, especially on real videos, which are more in-distribution for them – while on synthetic splits, their performance drops significantly. This is likely due to the fact that the models tend to leverage semantic cues rather than visual motion.\\n\\n5.2 RESULTS FOR ABSOLUTE VALUE PREDICTION\\n\\nTable 1 (right) shows results for absolute value prediction across physical properties and methods. This task is more challenging than relative comparison, as models must regress quantitative physical values rather than compare video pairs from the same viewpoint. Similar to the relative setting, the oracle estimator achieves near-perfect performance on test-1 and test-2, and strong per- formance on test-3, confirming that the task is largely solvable through visual cues, multi-view geometry, and physical laws. We highlight several key observations: (i) comparable performance across backbones. Despite being trained for generative tasks, video generative models perform on par with self-supervised models when predicting dynamic physical properties. (ii) friction remains challenging. Similar to the relative setting, both generative and self-supervised models struggle with friction estimation. Performance again improves with domain adaptation. (iii) MLLMs better on real test split than synthetic. MLLMs continue to perform better on the real test split than syn- thetic test splits, benefiting from their familiarity with real-world visual semantics. (iv) greater gap from oracle. The performance gap between video foundation models and the oracle is more pro- nounced here than in the relative setting, indicating that accurate physical value regression remains a significant challenge for current video models.\\n\\nFigure 4: Qualitative results.

In the first row, we illustrate an example from the elasticity absolute value prediction task. The video generative model, self-supervised model, and MLLMs predict values of 0.83, 0.96, and 1.0, respec- tively—all reasonably close to the ground-truth value of 0.89. In the second row, we present a friction relative value comparison task. The input consists of two videos, where the first exhibits a higher dynamic friction coefficient than the second. Both the video generative model and the MLLM correctly assign high likelihoods to this relationship (0.82 and 1.0, respectively), aligning with the ground truth. In contrast, the self-supervised model incorrectly predicts the reverse and does so with high confidence. Figure 4 (right) shows examples of the scatter plots for the absolute value predic- tion. More specifically, we show the scatter plots of video self-supervised model on the three test splits. It can be observed that the performance degrades from test-1 to test-3, as test-1 is of the same distribution as the synthetic training split, while test-2 is out-of-distribution synthetic test and test-3 is for real evaluation. We provide more scatter plots in Appendix Section F.\\n\\n6 CONCLUSION\\n\\nWe investigate the task of inferring dynamic physical properties—elasticity, viscosity, and fric- tion—from videos. To support this, we introduce a benchmark dataset with ground-truth annota- tions and evaluate a range of video foundation models under both absolute prediction and relative comparison settings. We adopt a simple architecture to extract physical cues from off-the-shelf gen- erative and self-supervised video models, and explore prompting strategies to elicit predictions from MLLMs. Experiments show that generative and self-supervised models have similar performance. MLLMs perform worse overall but improve with more informative prompting, especially on real- world data. However, all models fall short of the oracle, particularly in absolute value prediction. These results highlight the need to enhance physical reasoning in video models—a key direction for future research.\\n\\nTable 1: Results for relative value comparison and absolute value prediction.

The video generative model, self-supervised model, and MLLMs predict values of 0.83, 0.96, and 1.0, respec- tively—all reasonably close to the ground-truth value of 0.89. In the second row, we present a friction relative value comparison task. The input consists of two videos, where the first exhibits a higher dynamic friction coefficient than the second. Both the video generative model and the MLLM correctly assign high likelihoods to this relationship (0.82 and 1.0, respectively), aligning with the ground truth. In contrast, the self-supervised model incorrectly predicts the reverse and does so with high confidence. Figure 4 (right) shows examples of the scatter plots for the absolute value predic- tion. More specifically, we show the scatter plots of video self-supervised model on the three test splits. It can be observed that the performance degrades from test-1 to test-3, as test-1 is of the same distribution as the synthetic training split, while test-2 is out-of-distribution synthetic test and test-3 is for real evaluation. We provide more scatter plots in Appendix Section F.\\n\\n6 CONCLUSION\\n\\nWe investigate the task of inferring dynamic physical properties—elasticity, viscosity, and fric- tion—from videos. To support this, we introduce a benchmark dataset with ground-truth annota- tions and evaluate a range of video foundation models under both absolute prediction and relative comparison settings. We adopt a simple architecture to extract physical cues from off-the-shelf gen- erative and self-supervised video models, and explore prompting strategies to elicit predictions from MLLMs. Experiments show that generative and self-supervised models have similar performance. MLLMs perform worse overall but improve with more informative prompting, especially on real- world data. However, all models fall short of the oracle, particularly in absolute value prediction. These results highlight the need to enhance physical reasoning in video models—a key direction for future research.\\n\\nAcknowledgements.

However, in the presence of noise, these eigenvectors may still exhibit non-zero gradients in directions orthogonal to the manifold, causing them to acquire components in the noise directions [27, 28, 29, 30, 31] and consequently distorting the tangent space estimates.\\n\\nFortunately, a principle analogous to classical Fourier analysis applies: just as the low-frequency Fourier modes capture the underlying signal while high-frequency modes tend to encode noise [32, 33, 34], it is commonly observed that the eigenvectors corresponding to small eigenvalues of the graph Laplacian are robust to noise while the ones lying deeper into the spectrum may have nontrivial gradient in the noise directions [27, 28, 29, 30, 31], as demonstrated in Figure 1c. Building upon this insight, in this work, we propose an algorithm that estimates the tangent spaces at data points using the gradients of low- frequency global eigenvectors of the graph Laplacian. Moreover, we provide differential geometric and random matrix theoretic arguments to support our approach.\\n\\nOur contributions are as follows. We present a spectral algorithm, LEGO (Laplacian Eigenvector Gradi- ent Orthogonalization), for estimating tangent spaces at each data point by orthogonalizing the gradients of low-frequency global eigenvectors of the graph Laplacian derived from a noisy point cloud. Through comprehensive experiments we show that LEGO yields tangent space estimates that are significantly more robust to noise than those obtained via LPCA. We also demonstrate that this increased robustness results in significant improvements across multiple downstream tasks, including manifold learning [1, 2, 35, 3, 5, 36], boundary detection [37, 38, 39], and local intrinsic dimension estimation [13].\\n\\nOn the theoretical front, we offer two complementary justifications for our approach. First, we provide a differential geometric argument where we adopt a noise model in which clean data points lie on a d- dimensional smooth submanifold B in Rd+k, while the noisy observations lie in a tubular neighborhood T εr around B, where r is any number bounded by the global reach of B [40, 41] and ε ∈ (0,1) controls the tube width. In practice, r represents the maximum noise and and ε is a parameter that controls the noise level. In particular, we assume that noise perturbs data in directions normal to B. In this setting, the “horizontal space” at a noisy point—the subspace orthogonal to the noise direction—approximates the true tangent space of the corresponding clean point. Thus, estimating the horizontal space provides a principled approach to robust tangent space estimation. To formalize this approach, we study the eigenfunctions of the Laplacian on the tubular neighborhood T εr of B.\\n\\nSpecifically, we establish upper and lower bounds on the eigenvalue λ associated with an eigenfunction ϕ in terms of its horizontal and vertical energies, EB(ϕ) and E⊥ B(ϕ), which quantify the net gradient of ϕ across the horizontal spaces and the noise directions, respectively. These bounds indicate that for small ε, λ approximately scales as Ω(ε−2E⊥ B(ϕ)) with respect to the vertical energy of ϕ, and as O(EB(ϕ)) with respect to the horizontal energy. As a result, eigenfunctions with significant gradient across tube cross- sections necessarily correspond to large eigenvalues. Conversely, gradients of eigenfunctions associated with small eigenvalues are largely confined to the horizontal spaces.

However, in the presence of noise, these eigenvectors may still exhibit non-zero gradients in directions orthogonal to the manifold, causing them to acquire components in the noise directions [27, 28, 29, 30, 31] and consequently distorting the tangent space estimates.\\n\\nFortunately, a principle analogous to classical Fourier analysis applies: just as the low-frequency Fourier modes capture the underlying signal while high-frequency modes tend to encode noise [32, 33, 34], it is commonly observed that the eigenvectors corresponding to small eigenvalues of the graph Laplacian are robust to noise while the ones lying deeper into the spectrum may have nontrivial gradient in the noise directions [27, 28, 29, 30, 31], as demonstrated in Figure 1c. Building upon this insight, in this work, we propose an algorithm that estimates the tangent spaces at data points using the gradients of low- frequency global eigenvectors of the graph Laplacian. Moreover, we provide differential geometric and random matrix theoretic arguments to support our approach.\\n\\nOur contributions are as follows. We present a spectral algorithm, LEGO (Laplacian Eigenvector Gradi- ent Orthogonalization), for estimating tangent spaces at each data point by orthogonalizing the gradients of low-frequency global eigenvectors of the graph Laplacian derived from a noisy point cloud. Through comprehensive experiments we show that LEGO yields tangent space estimates that are significantly more robust to noise than those obtained via LPCA. We also demonstrate that this increased robustness results in significant improvements across multiple downstream tasks, including manifold learning [1, 2, 35, 3, 5, 36], boundary detection [37, 38, 39], and local intrinsic dimension estimation [13].\\n\\nOn the theoretical front, we offer two complementary justifications for our approach. First, we provide a differential geometric argument where we adopt a noise model in which clean data points lie on a d- dimensional smooth submanifold B in Rd+k, while the noisy observations lie in a tubular neighborhood T εr around B, where r is any number bounded by the global reach of B [40, 41] and ε ∈ (0,1) controls the tube width. In practice, r represents the maximum noise and and ε is a parameter that controls the noise level. In particular, we assume that noise perturbs data in directions normal to B. In this setting, the “horizontal space” at a noisy point—the subspace orthogonal to the noise direction—approximates the true tangent space of the corresponding clean point. Thus, estimating the horizontal space provides a principled approach to robust tangent space estimation. To formalize this approach, we study the eigenfunctions of the Laplacian on the tubular neighborhood T εr of B.\\n\\nSpecifically, we establish upper and lower bounds on the eigenvalue λ associated with an eigenfunction ϕ in terms of its horizontal and vertical energies, EB(ϕ) and E⊥ B(ϕ), which quantify the net gradient of ϕ across the horizontal spaces and the noise directions, respectively. These bounds indicate that for small ε, λ approximately scales as Ω(ε−2E⊥ B(ϕ)) with respect to the vertical energy of ϕ, and as O(EB(ϕ)) with respect to the horizontal energy. As a result, eigenfunctions with significant gradient across tube cross- sections necessarily correspond to large eigenvalues. Conversely, gradients of eigenfunctions associated with small eigenvalues are largely confined to the horizontal spaces. The practical implication is that the gradients of the low-frequency eigenvectors of the graph Laplacian, constructed from noisy data, exhibit relatively small components along noise directions, and thus their orthogonalization may provide a robust estimate of the tangent spaces.\\n\\nSecond, we provide a random matrix theoretic argument where we adopt an information plus noise- type model in which the clean data is injected with sub-Gaussian noise with variance proxy ε. Our data model is reminiscent of that presented in [42], with a key distinction being that our data dimension is held constant while ε = o(1) in the limit as the number of data points tends to infinity. This model generalizes from the case where the clean data lies on an embedded submanifold and the noise is confined to directions orthogonal to the tangent spaces. Using a Gaussian kernel with fixed bandwidth s, we construct the adjacency matrices and derive the corresponding random walk graph Laplacians, L for the clean data and L for the noisy data [43, 44].\\n\\nBy adapting techniques from the random graph literature (see, e.g., [45]), assuming that the variance √ proxy ε scales as O(1/ nlogn), we prove that the noisy Laplacian L converges to its clean counterpart L in operator norm at a rate of n−1/2 i.e., ∥L−L∥2 = O(n−1/2) with high probability.

Enumerate the eigenvalues of L and L, respectively, as follows:\\n\\n(40)\\n\\n(41)\\n\\nLet m ≪ n be fixed and assume that for each 1 ≤ i ≤ m − 1, it holds\\n\\n(42)\\n\\nThen for each 1 ≤ i ≤ m−1 fixed, there exists a choice of sign τi ∈ {±1} so that if ϕi and ψi, respectively, denote the eigenvectors of L and L with eigenvalues λi and ξi, then it holds\\n\\n(43)\\n\\nNote that there are natural improvements of Corollary 14 to settings where as n gets large L picks up eigenvalues with vanishingly small gaps. We would ask instead that first m eigenvalues of L break into finitely many small groups and the distances between such groups decay at a rate no worse than ω(n−1/2). In this scenario, the distance ∥ϕi − τiψi∥2 would be replaced with distance between the corresponding eigenspaces; i.e., convergence of the eigenvectors up to some orthogonal alignment matrix. For simplicity we do not state such improvements here.\\n\\n5. Experiments\\n\\nIn this section, we estimate tangent spaces on several noisy synthetic and real-world datasets using LPCA and LEGO, compare the estimated tangent spaces against the ground truth, and assess their utility in the following downstream tasks: (a) manifold learning, where we compute an intrinsic-dimensional parametrization of the underlying data manifold; (b) boundary detection, where we identify points that lie on or near the boundary of the data manifold; and (c) local intrinsic dimension estimation, where we determine the dimension of the tangent space at each data point. For completeness, we briefly describe how the estimated tangent spaces are utilized in these tasks in Section C.\\n\\nTo quantify the accuracy of a tangent space estimate Qj ∈ Rp×d at the j-th data point, we compute its deviation from the ground-truth tangent space Q∗ j, obtained from clean data. Specifically, we calculate the principal angles θj,1,...,θj,d between the subspaces spanned by Qj and Q∗ j [65]. The quality of the estimate is measured by the discrepancy score:\\n\\n(44)\\n\\nROBUST TANGENT SPACE ESTIMATION VIA LAPLACIAN EIGENVECTOR GRADIENT ORTHOGONALIZATION 13\\n\\n(b) Discrepancy between estimated and true tangent spaces\\n\\nLPCA (k, =9)\\n\\n(¢) 2D paramterization using true and estimated\\n\\n(d) Boundary detection using true and estimated tangent spaces\\n\\n©00\\n\\nGround truth\\n\\nLPCA\\n\\n(e) Functional variance explained by each principal direction\\n\\n1.00\\n\\nLEGO X; — V(\\n\\n0.75\\n\\n0.50\\n\\n0.25\\n\\n0.00\\n\\nFigure 3.

High-aspect ratio Swiss roll and a truncated torus. We begin with two synthetic datasets: a high–aspect-ratio Swiss roll and a truncated torus. For the Swiss roll, we generate n = 10700 uniformly distributed points in R3, forming the clean dataset Y (Figure 3a). Each point is perturbed by adding uniform noise in the direction normal to the underlying tangent space. Specifically, the noisy data points are given by Xj = Yj +ηjνj, where νj is outward normal to the tangent space at Yj and the coefficient ηj is uniformly distributed in (−ε,ε) where ε = 0.0175. The resulting noisy dataset X is shown in Figure 3a.\\n\\nFor the truncated torus, we sample n = 3617 uniformly distributed points on a subset of the torus in R3 as shown in Figure 4a. Here, each data point Yj is parameterized by (u,v) ∈ [0,2π)2 i.e. Yj ≡ Yj(uj,vj). We corrupt the clean data with heteroskedastic noise added in the normal direction to the tangent space at each point. The noisy data points are given by Xj = Yj + ηjνj, where νj is the outward normal direction to the tangent space at Yj and the coefficient ηj is uniformly distributed in (−ε(uj),ε(uj)) where ε(u) = 10−2 + 2.5 × 10−3(1 + cos(2u)). The noisy dataset X is shown in Figure 4a.\\n\\nFor both datasets, we estimate an orthonormal basis Qj of the 2-dimensional tangent space at each Xj using LPCA and LEGO, and then compute the discrepancy Dj (Eq. 44) between the estimates Qj and the ground-truth Q∗ j, as shown in Figure 3b and 4b. These results show that LEGO produces significantly more accurate estimates while LPCA estimates are highly sensitive to noise. Noise ablation (Figure 6) confirms LPCA estimates degrade rapidly with noise, whereas LEGO consistently yields reliable estimates.\\n\\nROBUST TANGENT SPACE ESTIMATION VIA LAPLACIAN EIGENVECTOR GRADIENT ORTHOGONALIZATION 13\\n\\n(b) Discrepancy between estimated and true tangent spaces\\n\\nLPCA (k, =9)\\n\\n(¢) 2D paramterization using true and estimated\\n\\n(d) Boundary detection using true and estimated tangent spaces\\n\\n©00\\n\\nGround truth\\n\\nLPCA\\n\\n(e) Functional variance explained by each principal direction\\n\\n1.00\\n\\nLEGO X; — V(\\n\\n0.75\\n\\n0.50\\n\\n0.25\\n\\n0.00\\n\\nFigure 3.

While humans can easily spot whether a piece of code \"looks right,\" determining if it actually works correctly, handles edge cases properly, and produces the intended result requires running and testing it. This is why today, we\\'re thrilled to announce BigCodeArena -- the first human-in-the-loop platform for evaluating code generation models through execution.\\n\\nInspired by LMArena for LLMs, we\\'ve built a platform that allows anyone to compare code generation models side-by-side, but with a crucial difference: you can actually run the code and see what it produces. Just submit a coding task, watch two different models generate solutions, execute both programs, and vote on which model produced better results. The outcomes are organized into a leaderboard that displays the community\\'s highest-rated models.\\n\\nMotivation\\n\\nThe field of code generation has long struggled with reliable evaluation methods. Traditional benchmarks like HumanEval test code against predefined test cases, but these represent only a tiny fraction of real-world programming tasks. Human evaluation platforms exist for general chatbots, but they fall short for code: reading raw source code and mentally simulating its execution is cognitively demanding and error-prone, especially for longer programs or complex UI applications.\\n\\nConsider this scenario:\\n\\nYou ask two AI models to build a responsive photo gallery website. Both generate code that looks syntactically correct. But which one is actually better? Without running the code, it\\'s nearly impossible to tell. One might produce a beautiful, functional grid layout, while the other might have subtle bugs or poor styling that only become apparent when rendered in a browser.\\n\\nThis observation led us to a key insight: execution feedback is essential for humans to judge code quality reliably. That\\'s exactly what BigCodeArena provides.\\n\\nThe BigCodeArena Platform\\n\\nBigCodeArena extends the Chatbot Arena framework with powerful features specifically designed for code evaluation:\\n\\nReal-Time Execution\\n\\nEvery code snippet generated by models is automatically executed in isolated sandbox environments. Whether it\\'s a Python script, a React web app, a PyGame game, or a C++ algorithm, you can see the actual output, not just the source code.\\n\\nMulti-Language & Framework Support\\n\\nWe currently support 10 languages (Python, JavaScript, TypeScript, HTML, C, C++, Java, Go, Rust, and Markdown) and 8 execution environments:\\n\\nWeb Frameworks: React, Vue, Core Web (vanilla HTML/CSS/JS)\\n\\nPython Frameworks: Streamlit, Gradio, PyGame\\n\\nDiagrams: Mermaid\\n\\nGeneral Purpose Interpreters: Python and JavaScript code interpreters, plus compiled language runners\\n\\nInteractive Testing\\n\\nUnlike static code comparison, you can actually interact with the generated applications:\\n\\nClick buttons and test UI elements in web apps\\n\\nPlay the games generated by models\\n\\nEdit the code and re-run it to test modifications\\n\\nView visual outputs like plots, charts, and diagrams\\n\\nMulti-Turn Conversations\\n\\nReal programming isn\\'t one-and-done. BigCodeArena supports multi-turn interactions, allowing you to refine requirements, ask for features to be added, or request bug fixes -- just like working with a real coding assistant.\\n\\nWhat We\\'ve Learned: 5 Months of Community Evaluation\\n\\nSince launching in February 2025, BigCodeArena has collected over 14,000 conversations from more than 500 unique users, with 4,700+ high-quality preference votes comparing 10 frontier LLMs.\\n\\nProgramming Topics in the Wild\\n\\nOur users have explored remarkably diverse coding scenarios:\\n\\nWeb Design (36%): Building responsive websites, interactive dashboards, and web applications\\n\\nProblem Solving (23%): Algorithms, data structures, and computational challenges\\n\\nGame Development (16%): Creating interactive games with physics, collision detection, and graphics\\n\\nScientific Computing (14%): Data analysis, visualization, and numerical simulations\\n\\nCreative Coding (8%): Artistic visualizations, generative art, and experimental interfaces\\n\\nDiagram Creation (3%): Flowcharts, system architectures, and data visualizations\\n\\nLanguage and Framework Popularity\\n\\nPython dominates with over 4,000 conversations, followed by JavaScript/TypeScript (3,359), HTML (1,601), and C++ (642). Among frameworks, direct Python interpreters lead usage (6,000 sessions), with React (2,729), Core Web (1,574), Streamlit (1,254), and PyGame (1,087) also seeing heavy use.\\n\\nUser Interaction Patterns\\n\\nMost interactions are focused and efficient: 76% of conversations consist of just 2 turns (one request, one response), with a mean conversation length of 4.12 messages. However, the platform supports extended multi-turn debugging sessions when needed, with some conversations exceeding 10 turns as users refine complex applications.\\n\\nModel Rankings from Community Votes\\n\\nFrom our 14K conversations, we filtered for high-quality pairwise comparisons: conversations with at least two turns and actual code execution. This yielded 4,731 voting samples, with each evaluated model receiving at least 700 votes. We aggregate these votes into Elo ratings using the Bradley-Terry model, which estimates the probability that one model beats another based on head-to-head comparisons.\\n\\nTo ensure robust rankings, we use 100 bootstrap resamples to construct 95% confidence intervals, so we can identify statistically significant performance differences between models.\\n\\nWe evaluate models under three settings to control for different factors:\\n\\nAll Data: Uses all pairwise comparisons regardless of execution environment or programming language\\n\\nEnvironment Matched: Only compares models when both were executed in the same sandbox (e.g., both in React or both in PyGame)\\n\\nLanguage Matched: Further restricts comparisons to the same programming language\\n\\nRankings remain remarkably consistent across all three settings, revealing clear performance tiers:\\n\\nTop Tier: o3-mini and o1-mini consistently lead with the highest Elo ratings and tight confidence intervals. These models maintain top performance regardless of environment or language constraints, showing strong robustness across coding scenarios. Claude-3.5-Sonnet follows closely, particularly excelling when language is controlled.\\n\\nMid Tier: GPT-4o, o1, and Gemini-2.0-Pro/Flash form a competitive middle tier. GPT-4o shows some sensitivity to language matching, suggesting room for improvement in multilingual consistency.\\n\\nOpen Source Models: Qwen2.5 variants and Llama-3.3-70B lag behind frontier proprietary models, highlighting the performance gap that remains between leading closed and open models.\\n\\nFigure: Overall win rate heatmaps (percentage of all pairwise comparisons won) of each model in the sessions across languages (left) and execution environments (right). For each category, we only keep models that appear in at least 3 conversation sessions.\\n\\nPerformance Across Languages\\n\\nBreaking down performance by programming language reveals interesting patterns:\\n\\nTop-tier models like o3-mini and o1-mini achieve dominant win rates in mainstream languages like Python, Java, and C++\\n\\nGemini-2.0-Pro shows particular strength in Rust, achieving the highest win rate in that category\\n\\nDifferent models exhibit distinct areas of expertise, with frontier models excelling in different niches\\n\\nOpen models like Qwen2.5 variants show inconsistent performance, particularly struggling with Rust and Go\\n\\nPerformance Across Execution Environments\\n\\nAnalyzing win rates by execution environment reveals how models handle different runtime contexts:\\n\\nRobust Performers: o3-mini maintains consistently strong performance across React, Streamlit, Gradio, Core Web, and PyGame, demonstrating excellent environmental adaptability.\\n\\nStable but Selective: Claude-3.5-Sonnet and Gemini-2.0-Flash show generally stable performance but with reduced win rates in complex UI-heavy environments like Vue and Mermaid.\\n\\nFramework-Specific Weaknesses: Qwen2.5 models, while competitive in some web frameworks (Core Web, React), struggle significantly with interactive and visualization-oriented environments like PyGame, Vue, and Mermaid. These environments often require precise handling of control flow, graphics rendering, and package dependencies.\\n\\nThese results highlight an important insight: aggregate Elo scores don\\'t tell the whole story. Some models remain brittle under specific runtime constraints, and execution environment matters significantly for real-world deployment.\\n\\nTwo New Benchmarks: BigCodeReward and AutoCodeArena\\n\\nTo advance research beyond crowdsourced evaluation, we\\'re releasing two complementary benchmarks:\\n\\nBigCodeReward: Evaluating Reward Models for Code\\n\\nBuilding on our 4,700+ preference votes, BigCodeReward tests how well LLMs can judge code quality when acting as reward models. The key finding? Execution results dramatically improve judgment accuracy.\\n\\nWhen models can see execution outputs (screenshots of web apps, game visuals, program logs), their alignment with human preferences increases substantially:\\n\\nClaude-Sonnet-4: 56.7% → 62.3% accuracy\\n\\nGPT-4o: 54.6% → 63.8% accuracy\\n\\nQwen2.5-VL-72B: 58.7% → 66.2% accuracy\\n\\nThis reinforces our core thesis: you can\\'t reliably judge code without running it -- and this applies to both humans and AI judges.\\n\\nAutoCodeArena: Automated Code Generation Benchmarks\\n\\nInspired by Arena-Hard-Auto, AutoCodeArena provides a scalable way to evaluate new models without waiting for thousands of human votes. We carefully selected 600 representative prompts from our crowdsourced data, spanning all programming topics and frameworks.\\n\\nUsing automated LLM judges (Claude-3.7-Sonnet) to evaluate code execution results against a GPT-4.1 baseline, we can rapidly benchmark new models. This approach enables weekly leaderboard updates as new models are released.\\n\\nOur automated benchmark evaluated 20+ cutting-edge models, including recently released systems:\\n\\nTop Performers:\\n\\nGPT-5 -- Establishes new state-of-the-art by a significant margin\\n\\nClaude-Opus-4 and Claude-Sonnet-4 -- Strong second tier, excelling in reasoning-heavy tasks\\n\\nQwen3-Coder, Kimi-K2, GLM-4.5 -- Leading open models that narrow the gap with mid-tier proprietary systems\\n\\nFigure: Win rates of recent LLMs on AutoCodeArena against a GPT-4.1 baseline, judged by Claude-3.7-Sonnet. The 50% mark represents parity with GPT-4.1. Models above this line outperform the baseline, while those below underperform. Error bars show 95% confidence intervals. Note: Claude-3.7-Sonnet is excluded from rankings to avoid self-judgment bias, and GPT-4.1 appears only as the reference baseline.\\n\\nThe results show that while proprietary models maintain an edge, open-source models are rapidly closing the gap, with some approaching GPT-4.1-level performance.\\n\\nTry It Yourself\\n\\nBigCodeArena is open to everyone -- no account required!

Traditional reasoning LLMs often rely on generating explicit intermediate steps in language to solve complex reasoning tasks. Recent work shifts reasoning from discrete text tokens to latent continuous tokens, where models perform iterative computation internally with- out generating external text (Chen et al., 2025; Zhu et al., 2025). Early work validated the benefit of extra computation through unstructured means, such as learnable pause tokens (Goyal et al., 2024) or even semantically meaningless filler tokens (Pfau et al., 2024), which improved performance on rea- soning tasks by simply extending the model’s processing time implicitly. Building on this implicit- compute view, iCoT moves from explicit to implicit CoT via distillation (Deng et al., 2023) and curriculum (Deng et al., 2024), progressively removing CoT while aligning internal states around answer prediction. This allows the model to internalize reasoning without generating text rationales at inference. Coconut (Hao et al., 2024) introduces “continuous thought” by feeding the last hidden state directly as the next input embedding, showing breadth-first search–like parallel exploration and fewer thinking tokens versus CoT on logical reasoning tasks.

Unlike chain-of-thought (CoT) reasoning traces, latent reasoning lacks direct supervision because latent traces are unobserved during training. Consequently, its performance is typically inferior to models trained with full CoT supervision (Deng et al., 2023; 2024). To address this, we leverage the observed reasoning traces C to guide latent reasoning during training, as illustrated in Fig. 3. This guidance is realized through distillation from teacher to student. Following Shen et al. (2025), we adopt a self-supervised framework in which the same model learns from explicit reasoning traces (as the teacher) as well as latent tokens (as the student).\\n\\nWe introduce KAVA, model with a novel objective, KV-cache distillation, to transfer relevant infor- mation from the teacher’s reasoning trace to the student.

Under Review.\\n\\n3.2 KV-CACHE DISTILLATION\\n\\nTo provide an additional supervision signal from the full chain-of-thought (CoT) trace to the la- tent reasoning process, KAVA uses a distillation method based on matching the respective key- value (KV) caches (last term in Eq. 2). We apply redundancy-aware KV-cache compression to the teacher’s cache prior to distillation. This encourages the student to generate compressed and abstract representations, while preserving crucial reasoning information from the CoT trace.\\n\\nWe first extract the KV-cache for both the explicit reasoning trace (teacher) and the latent thought (student). Each cache consists of key and value tensors for every token i, layer l ∈ (1,...,L), and attention head h ∈ (1,...,H) of the transformer:\\n\\nwhere t stands for teacher and s for the student.We use the last Jacobi iteration T to extract the KV-cache of the student.\\n\\nAddressing the Length Mismatch. The teacher cache ( K V and student cache (Kj, V) dif- fer in sequence length, since M < Nc¢. To align them wh enforcing compression, we apply d obtain a compressed teacher redundancy-aware KV eviction (Park et al| [2025]|Cai et al} cache K, y € RMHxLxd gpecifically, we adapt R-KV C et al e to select the top M ih KV-pairs (see App based on a combined redundancy—importance score\\n\\nwhere λ is a hyperparameter controlling the balance between redundancy and importance. The evic- tion method is only applied during training, since the student is distilled to generate the compressed KV-cache. Since eviction method is not applied during inference, we leverage the answer tokens from the training data for the importance score computation. For each layer and head, we compute the attention score using the teacher’s keys K·,h,l ∈ RNC×d and queries corresponding to the answer t tokens tokens Q·,h,l ∈ RNA×d:\\n\\n√\\n\\nThe importance score is then aggregated over all answer tokens1:\\n\\nNote that this computation incurs negligible overhead, since the attention scores were computed during the teacher’s forward pass. Following R-KV2, we compute a redundancy score Ri,h,l as the average pairwise cosine similarity among all key vectors and normalize via softmax.\\n\\nFinally, we use the score values Si,h,l (Eq. 4) to select top-M keys (and their corresponding values) for each head and layer in the teacher’s KV-cache. Full details and pseudocode are provided in App. A.\\n\\nKV Matching. Independent KV-pair eviction across layers and heads alters the cache’s structure and contents, yet it remains usable by the original model (see Figure 1b). However, there no longer exists a correspondence between the resulting cache and hard tokens. For that reason, we cannot ap- ply standard ways of distillation, matching the activations of the teacher and student model.

Under Review.\\n\\n3.2 KV-CACHE DISTILLATION\\n\\nTo provide an additional supervision signal from the full chain-of-thought (CoT) trace to the la- tent reasoning process, KAVA uses a distillation method based on matching the respective key- value (KV) caches (last term in Eq. 2). We apply redundancy-aware KV-cache compression to the teacher’s cache prior to distillation. This encourages the student to generate compressed and abstract representations, while preserving crucial reasoning information from the CoT trace.\\n\\nWe first extract the KV-cache for both the explicit reasoning trace (teacher) and the latent thought (student). Each cache consists of key and value tensors for every token i, layer l ∈ (1,...,L), and attention head h ∈ (1,...,H) of the transformer:\\n\\nwhere t stands for teacher and s for the student.We use the last Jacobi iteration T to extract the KV-cache of the student.\\n\\nAddressing the Length Mismatch. The teacher cache ( K V and student cache (Kj, V) dif- fer in sequence length, since M < Nc¢. To align them wh enforcing compression, we apply d obtain a compressed teacher redundancy-aware KV eviction (Park et al| [2025]|Cai et al} cache K, y € RMHxLxd gpecifically, we adapt R-KV C et al e to select the top M ih KV-pairs (see App based on a combined redundancy—importance score\\n\\nwhere λ is a hyperparameter controlling the balance between redundancy and importance. The evic- tion method is only applied during training, since the student is distilled to generate the compressed KV-cache. Since eviction method is not applied during inference, we leverage the answer tokens from the training data for the importance score computation. For each layer and head, we compute the attention score using the teacher’s keys K·,h,l ∈ RNC×d and queries corresponding to the answer t tokens tokens Q·,h,l ∈ RNA×d:\\n\\n√\\n\\nThe importance score is then aggregated over all answer tokens1:\\n\\nNote that this computation incurs negligible overhead, since the attention scores were computed during the teacher’s forward pass. Following R-KV2, we compute a redundancy score Ri,h,l as the average pairwise cosine similarity among all key vectors and normalize via softmax.\\n\\nFinally, we use the score values Si,h,l (Eq. 4) to select top-M keys (and their corresponding values) for each head and layer in the teacher’s KV-cache. Full details and pseudocode are provided in App. A.\\n\\nKV Matching. Independent KV-pair eviction across layers and heads alters the cache’s structure and contents, yet it remains usable by the original model (see Figure 1b). However, there no longer exists a correspondence between the resulting cache and hard tokens. For that reason, we cannot ap- ply standard ways of distillation, matching the activations of the teacher and student model. Instead, we propose distilling the keys and values directly.\\n\\nTo this end, we distill the latent reasoning cache to match the compressed teacher’s cache, effectively guiding the latent model to approximate the full reasoning process in a more efficient and abstract form.

A validation prompt is used: “Mrs. Taylor bought two smart televisions that cost $650 each. If the total sales price had a 25% discount, how much did Mrs. Taylor pay for the two televisions?”. Latent thoughts 16-24 are not shown due to their limited semantic value. 3 tokens with the highest logits are shown for each latent thought. Tokens T1, T2, T3, T4, T5, T6, T7 stand for total, cost, dollars, discount, original, gross, and price respectively.

In contrast, models trained on the GSM8k-AUG-NL dataset resist this straightforward read-out method. We hypothesize that this is caused by the KV-cache distillation employed by KAVA —in a dataset with shorter traces, such as GSM8k-AUG, most of the time the KV-cache re- tains all of its content after eviction. On longer traces, such as the ones found in GSM8k-AUG-NL, not all content of the KV-cache is preserved, and, furthermore, each latent thought’s distillation tar- get may consist of keys and values originating from different tokens of the teacher’s CoT. This can prevent latent thought to hard token correspondence from arising.\\n\\n5.2 TEACHER-STUDENT KV-CACHE CORRESPONDENCE\\n\\nFigure 7: Cosine similarity of Keys in the latent CoT with Keys of the ground truth averaged across heads and layers.

The results for Keys, averaged over attention heads and layers are presented in the Fig. 7. We observe that when comparing to the KV- cache after eviction, the similarities near the diagonal (x = y) tend to be higher, which is expected, as it is encouraged by the KV distillation. Furthermore, the values to the right of the diagonal are higher when comparing with the full CoT, which is desired, as this represents the compression of the original CoT (i.e. the key of some n-th latent token is similar to the key of an m-th hard token where n < m).

Our central con- tribution is the demonstration that a compressed KV-cache, despite losing direct token correspon- dence, can serve as a rich, stepwise supervisory signal for a latent reasoning student. By aligning the student’s latent trajectory with the teacher’s internal reasoning dynamics in KV space, KAVA over- comes the limitations of token-level distillation and the inefficiencies of verbose Chain-of-Thought (CoT) traces. KAVA consistently outperforms strong latent reasoning baselines, scales effectively to larger backbones, and shows robust performance on natural-language reasoning datasets where prior methods often struggle. While the advancement of latent reasoning is linked to the availability of large-scale training data to instill novel reasoning dynamics, our work establishes compressed KV-cache distillation as a scalable and effective supervision technique for developing efficient and powerful reasoning models.\\n\\nREFERENCES\\n\\nZefan Cai, Yichi Zhang, Bofei Gao, Yuliang Liu, Yucheng Li, Tianyu Liu, Keming Lu, Wayne Xiong, Yue Dong, Junjie Hu, et al.

Traditional chain-of-thought (CoT) reasoning in LLMs is computationally expensive due to verbose traces, while latent reasoning offers efficiency but lacks direct supervision. KAVA bridges this gap by distilling knowledge from a teacher model's compressed KV-cache into a latent reasoning student, using continuous latent tokens to align stepwise KV trajectories. This method maintains the accuracy of CoT-trained models while enhancing efficiency and scalability. KAVA outperforms existing latent reasoning methods, showing less performance degradation when transitioning from equation-only to natural-language traces and scaling effectively to larger models. The approach provides a scalable supervision signal for latent reasoning, combining CoT accuracy with latent inference efficiency, and is significant for AI professionals seeking efficient, deployable reasoning models.`\n", + "12\n", "\n", + "Terry Yue Zhuo\n", "\n", - "\u001b[0m" - ] - }, - { - "name": "stderr", + "terryyz\n", + "\n", + "bigcode\n", + "\n", + "Evaluating the quality of AI-generated code is notoriously difficult.

In 2025, it is more feasible than ever to run truly competitive models on-device. dots.ocr, a 3B parameter OCR model from RedNote, surpasses Gemini 2.5 Pro in OmniDocBench, making OCR a truly no compromises on-device use case. Running models on-device is certainly appealing to developers: no smuggling API keys, zero cost, and no network required. However, if we want these models to run on-device, we need to be mindful of the limited compute and power budgets.\\n\\nEnter the Neural Engine, Apple\\'s custom AI accelerator that has shipped with every Apple device since 2017. This accelerator is designed for high performance whilst sipping battery power. Some of our testing has found the Neural Engine to be 12x more power efficient than CPU, and 4x more power efficient than GPU.\\n\\nWhilst this all sounds very appealing, unfortunately the Neural Engine is only accessible through Core ML, Apple\\'s closed source ML framework. Furthermore, even just converting a model from PyTorch to Core ML can present some challenges, and without a preconverted model or some knowledge of the sharp edges it can be arduous for developers. Luckily, Apple also offers MLX, a more modern and flexible ML framework that targets the GPU (not the Neural Engine), and can be used in conjunction with Core ML.\\n\\nIn this three part series, we will provide a reasoning trace of how we converted dots.ocr to run on-device, using a combination of CoreML and MLX. This process should be applicable to many other models, and we hope that this will help highlight the ideas and tools needed for developers looking to run their own models on-device.\\n\\nTo follow along, clone the repo. You\\'ll need uv and hf installed to run the setup command:\\n\\n./boostrap.sh\\n\\nIf you just want to skip ahead and use the converted model, you can download it here.\\n\\nConversion\\n\\nConverting from PyTorch to CoreML is a two step process:\\n\\nCapturing your PyTorch execution graph (via torch.jit.trace or, the more modern approach of torch.export).\\n\\nCompiling this converted graph to an .mlpackage using coremltools.\\n\\nWhilst we do have a few knobs we can tweak for step 2, most of our control is in step 1, the graph we feed to coremltools.\\n\\nFollowing the programmers litany of make it work, make it right, make it fast, we will first focus on getting the conversion working on GPU, in FLOAT32, and with static shapes. Once we have this working, we can dial down the precision and try and move to the Neural Engine.\\n\\nDots.OCR\\n\\nDots.OCR consists of two key components: A 1.2B parameter vision encoder trained from scratch, based on the NaViT architecture, and a Qwen2.5-1.5B backbone. We will be using CoreML to run the vision encoder, and MLX to run the LM backbone.\\n\\nStep 0: Understand and simplify the model\\n\\nIn order to convert a model, it\\'s best to understand the structure and function before getting started. Looking at the original vision modelling file here, we can see that the vision encoder is similar to the QwenVL family. Like many vision encoders, the vision encoder for dots works on a patch basis, in this case 14x14 patches. The dots vision encoder is capable of processing videos and batches of images. This gives us an opportunity to simplify by only processing a single image at a time. This approach is frequent in on-device apps, where we convert a model that provides the essential functions and iterate if we want to process multiple images.\\n\\nWhen kicking off the conversion process, it\\'s best to start with a minimal viable model. This means removing any bells and whistles that are not strictly necessary for the model to function. In our case, dots has many different attention implementations available for both the vision encoder and the LM backbone. CoreML has lots of infrastructure oriented around the scaled_dot_product_attention operator, which they introduced in iOS 18. We can simplify the model by removing all of the other attention implementations and just focusing on simple sdpa (not the memory efficient variant) for now, commit here.\\n\\nOnce we\\'ve done this, we see a scary warning message when we load the model:\\n\\nSliding Window Attention is enabled but not implemented for `sdpa`; unexpected results may be encountered.\\n\\nThe model doesn\\'t require Sliding Window Attention to function, so we can happily move on.\\n\\nStep 1: A simple harness\\n\\nUsing torch.jit.trace is still the most mature method for converting models to CoreML. We usually encapsulate this in a simple harness that allows you to modify the compute units used and the precision selected.\\n\\nYou can check out the initial harness here. If we run the following on the original code implementation:\\n\\nuv run convert.py --precision FLOAT32 --compute_units CPU_AND_GPU\\n\\nWe should bump into the first (of many) issues.\\n\\nStep 2: Bug hunting\\n\\nIt is rare that a model will convert first time. Often, you will need to progressively make changes further and further down the execution graph until you reach the final node.\\n\\nOur first issue is the following error:\\n\\nERROR - converting \\'outer\\' op (located at: \\'vision_tower/rotary_pos_emb/192\\'): In op \"matmul\", when x and y are both non-const, their dtype need to match, but got x as int32 and y as fp32\\n\\nLuckily this error gives us quite a bit of information. We can look at the VisionRotaryEmbedding layer and see the following code:\\n\\ndef forward(self, seqlen: int) -> torch.Tensor: seq = torch.arange(seqlen, device=self.inv_freq.device, dtype=self.inv_freq.dtype) freqs = torch.outer(seq, self.inv_freq) return freqs\\n\\nAlthough torch.arange has a dtype argument, coremltools ignores this for arange and always outputs int32. We can simply add a cast after the arange to fix this issue, commit here.\\n\\nAfter fixing this, running the conversion again leads us to our next issue at repeat_interleave:\\n\\nERROR - converting \\'repeat_interleave\\' op (located at: \\'vision_tower/204\\'): Cannot add const [None]\\n\\nWhilst this error is less informative, we only have a single call to repeat_interleave in our vision encoder:\\n\\ncu_seqlens = torch.repeat_interleave(grid_thw[:, 1] * grid_thw[:, 2], grid_thw[:, 0]).cumsum( dim=0, dtype=grid_thw.dtype if torch.jit.is_tracing() else torch.int32, )\\n\\ncu_seqlens is used for masking variable length sequences in flash_attention_2. It\\'s derived from the grid_thw tensor, which represents time, height and width. Since we are only processing a single image, we can simply remove this call, commit here.\\n\\nOnto the next! This time, we get a more cryptic error:\\n\\nERROR - converting \\'_internal_op_tensor_inplace_fill_\\' op (located at: \\'vision_tower/0/attn/301_internal_tensor_assign_1\\'): _internal_op_tensor_inplace_fill does not support dynamic index\\n\\nThis is again due to the masking logic to handle variable length sequences. Since we are only processing a single image (not a video or batch of images), we don\\'t really need attention masking at all! Therefore, we can just use a mask of all True. To prepare ourselves for the Neural Engine conversion, we also switch from using a boolean mask to a float mask of all zeros, as the Neural Engine does not support bool tensors commit here\\n\\nWith all of this done, the model should now successfully convert to CoreML! However, when we run the model, we get the following error:\\n\\nerror: \\'mps.reshape\\' op the result shape is not compatible with the input shape\\n\\nThis reshape could be in multiple places! Luckily, we can use a previous warning message to help us track down the issue:\\n\\nTracerWarning: Iterating over a tensor might cause the trace to be incorrect. Passing a tensor of different shape won\\'t change the number of iterations executed (and might lead to errors or silently give incorrect results). for t, h, w in grid_thw:\\n\\nMost ML compilers do not like dynamic control flow. Luckily for us, as we are only processing a single image, we can simply remove the loop and process the single h, w pair, commit here.\\n\\nAnd there we have it! If we run the conversion again, we should see that the model successfully converts and matches the original PyTorch precision:\\n\\nMax difference: 0.006000518798828125, Mean difference: 1.100682402466191e-05\\n\\nStep 3: Benchmarking\\n\\nNow that we\\'ve got the model working, let\\'s evaluate the size and performance. The good news is the model is working, the bad news is that it\\'s over 5GB! This is completely untenable for on device deployment! To benchmark the computation time, we can use the built in XCode tooling by calling:\\n\\nopen DotsOCR_FLOAT32.mlpackage\\n\\nwhich will launch the XCode inspector for the model. After clicking + Performance Report and launching a report on all compute devices, you should see something like the following:\\n\\nOver a second for a single forward pass of the vision encoder! We have lots of more work.\\n\\nIn the second part of this series, we will work on the integration between CoreML and MLX, to run the full model on-device. In the third part, we will dive deep into the optimizations required to get this model running on the Neural Engine, including quantization and dynamic shapes.\\n\\nMore Articles from our Blog\\n\\nSwift Transformers Reaches 1.0 — and Looks to the Future\\n\\nBy September 26, 2025 • 26\\n\\nWWDC 24: Running Mistral 7B with Core ML\\n\\nBy July 22, 2024 • 62\\n\\nCommunity\\n\\nstopthinking\\n\\n6 days ago\\n\\nnone of the commits links work\\n\\nFL33TW00D-HF\\n\\nArticle author 6 days ago\\n\\nThanks for the flag!

In 2025, it is more feasible than ever to run truly competitive models on-device. dots.ocr, a 3B parameter OCR model from RedNote, surpasses Gemini 2.5 Pro in OmniDocBench, making OCR a truly no compromises on-device use case. Running models on-device is certainly appealing to developers: no smuggling API keys, zero cost, and no network required. However, if we want these models to run on-device, we need to be mindful of the limited compute and power budgets.\\n\\nEnter the Neural Engine, Apple\\'s custom AI accelerator that has shipped with every Apple device since 2017. This accelerator is designed for high performance whilst sipping battery power. Some of our testing has found the Neural Engine to be 12x more power efficient than CPU, and 4x more power efficient than GPU.\\n\\nWhilst this all sounds very appealing, unfortunately the Neural Engine is only accessible through Core ML, Apple\\'s closed source ML framework. Furthermore, even just converting a model from PyTorch to Core ML can present some challenges, and without a preconverted model or some knowledge of the sharp edges it can be arduous for developers. Luckily, Apple also offers MLX, a more modern and flexible ML framework that targets the GPU (not the Neural Engine), and can be used in conjunction with Core ML.\\n\\nIn this three part series, we will provide a reasoning trace of how we converted dots.ocr to run on-device, using a combination of CoreML and MLX. This process should be applicable to many other models, and we hope that this will help highlight the ideas and tools needed for developers looking to run their own models on-device.\\n\\nTo follow along, clone the repo. You\\'ll need uv and hf installed to run the setup command:\\n\\n./boostrap.sh\\n\\nIf you just want to skip ahead and use the converted model, you can download it here.\\n\\nConversion\\n\\nConverting from PyTorch to CoreML is a two step process:\\n\\nCapturing your PyTorch execution graph (via torch.jit.trace or, the more modern approach of torch.export).\\n\\nCompiling this converted graph to an .mlpackage using coremltools.\\n\\nWhilst we do have a few knobs we can tweak for step 2, most of our control is in step 1, the graph we feed to coremltools.\\n\\nFollowing the programmers litany of make it work, make it right, make it fast, we will first focus on getting the conversion working on GPU, in FLOAT32, and with static shapes. Once we have this working, we can dial down the precision and try and move to the Neural Engine.\\n\\nDots.OCR\\n\\nDots.OCR consists of two key components: A 1.2B parameter vision encoder trained from scratch, based on the NaViT architecture, and a Qwen2.5-1.5B backbone. We will be using CoreML to run the vision encoder, and MLX to run the LM backbone.\\n\\nStep 0: Understand and simplify the model\\n\\nIn order to convert a model, it\\'s best to understand the structure and function before getting started. Looking at the original vision modelling file here, we can see that the vision encoder is similar to the QwenVL family. Like many vision encoders, the vision encoder for dots works on a patch basis, in this case 14x14 patches. The dots vision encoder is capable of processing videos and batches of images. This gives us an opportunity to simplify by only processing a single image at a time. This approach is frequent in on-device apps, where we convert a model that provides the essential functions and iterate if we want to process multiple images.\\n\\nWhen kicking off the conversion process, it\\'s best to start with a minimal viable model. This means removing any bells and whistles that are not strictly necessary for the model to function. In our case, dots has many different attention implementations available for both the vision encoder and the LM backbone. CoreML has lots of infrastructure oriented around the scaled_dot_product_attention operator, which they introduced in iOS 18. We can simplify the model by removing all of the other attention implementations and just focusing on simple sdpa (not the memory efficient variant) for now, commit here.\\n\\nOnce we\\'ve done this, we see a scary warning message when we load the model:\\n\\nSliding Window Attention is enabled but not implemented for `sdpa`; unexpected results may be encountered.\\n\\nThe model doesn\\'t require Sliding Window Attention to function, so we can happily move on.\\n\\nStep 1: A simple harness\\n\\nUsing torch.jit.trace is still the most mature method for converting models to CoreML. We usually encapsulate this in a simple harness that allows you to modify the compute units used and the precision selected.\\n\\nYou can check out the initial harness here. If we run the following on the original code implementation:\\n\\nuv run convert.py --precision FLOAT32 --compute_units CPU_AND_GPU\\n\\nWe should bump into the first (of many) issues.\\n\\nStep 2: Bug hunting\\n\\nIt is rare that a model will convert first time.

This approach addresses the high computational cost of traditional chain-of-thought (CoT) reasoning by offering an efficient alternative without sacrificing accuracy. KAVA achieves this by transferring knowledge from a teacher model's compressed KV-cache to a latent reasoning student, aligning stepwise KV trajectories with continuous latent tokens. The framework not only maintains the accuracy of CoT-trained models but also enhances efficiency and scalability. KAVA demonstrates superior performance compared to existing latent reasoning methods, with minimal performance loss when shifting from equation-only to natural-language traces. It effectively scales to larger models, providing a scalable supervision signal that combines CoT accuracy with latent inference efficiency.

You can think of this initial chapter as a recipe you can just follow. It\\'s a \"shoot first, ask questions later\" kind of post.\\n\\nYou\\'ll learn how to:\\n\\nLoad a quantized model using BitsAndBytes\\n\\nConfigure low-rank adapters (LoRA) using Hugging Face\\'s peft\\n\\nLoad and format a dataset\\n\\nFine-tune the model using the supervised fine-tuning trainer (SFTTrainer) from Hugging Face\\'s trl\\n\\nUse the fine-tuned model to generate a sentence\\n\\nJupyter Notebook\\n\\nThe Jupyter notebook corresponding to this post is part of the official Fine-Tuning LLMs repository on GitHub. You can also run it directly in Google Colab\\n\\nSetup\\n\\nIf you\\'re running it on Colab, you\\'ll need to pip install a few libraries: datasets, bitsandbytes, and trl.\\n\\nFor better reproducibility during training, however, use the pinned versions instead:\\n\\n#!pip install datasets bitsandbytes trl !pip install transformers==4.55.2 peft==0.17.0 accelerate==1.10.0 trl==0.21.0 bitsandbytes==0.47.0 datasets==4.0.0 huggingface-hub==0.34.4 safetensors==0.6.2 pandas==2.2.2 matplotlib==3.10.0 numpy==2.0.2\\n\\nImports\\n\\nFor the sake of organization, all libraries needed throughout the code used are imported at its very start. For this post, we\\'ll need the following imports:\\n\\nimport os import torch from datasets import load_dataset from peft import get_peft_model, LoraConfig, prepare_model_for_kbit_training from transformers import AutoModelForCausalLM, AutoTokenizer, BitsAndBytesConfig from trl import SFTConfig, SFTTrainer\\n\\nLoading a Quantized Base Model\\n\\nWe start by loading a quantized model, so it takes up less space in the GPU\\'s RAM. A quantized model replaces the original weights with approximate values that are represented by fewer bits. The simplest and most straightforward way to quantize a model is to turn its weights from 32-bit floating-point (FP32) numbers into 4-bit floating-point numbers (NF4). This simple yet powerful change already reduces the model\\'s memory footprint by roughly a factor of eight.\\n\\nWe can use an instance of BitsAndBytesConfig as the quantization_config argument while loading a model using the from_pretrained() method. To keep it flexible, so you can try it out with any other model of your choice, we\\'re using Hugging Face\\'s AutoModelForCausalLM. The repo you choose to use determines the model being loaded.\\n\\nWithout further ado, here\\'s our quantized model being loaded:\\n\\nbnb_config = BitsAndBytesConfig( load_in_4bit=True, bnb_4bit_quant_type=\"nf4\", bnb_4bit_use_double_quant=True, bnb_4bit_compute_dtype=torch.float32 ) repo_id = \\'microsoft/Phi-3-mini-4k-instruct\\' model = AutoModelForCausalLM.from_pretrained( repo_id, device_map=\"cuda:0\", quantization_config=bnb_config )\\n\\n\"The Phi-3-Mini-4K-Instruct is a 3.8B parameters, lightweight, state-of-the-art open model trained with the Phi-3 datasets that includes both synthetic data and the filtered publicly available websites data with a focus on high-quality and reasoning dense properties. The model belongs to the Phi-3 family with the Mini version in two variants 4K and 128K which is the context length (in tokens) that it can support.\" Source: Hugging Face Hub\\n\\nOnce the model is loaded, you can see how much space it occupies in memory using the get_memory_footprint() method.\\n\\nprint(model.get_memory_footprint()/1e6)\\n\\n2206.347264\\n\\nEven though it\\'s been quantized, the model still takes up a bit more than 2 gigabytes of RAM. The quantization procedure focuses on the linear layers within the Transformer decoder blocks (also referred to as \"layers\" in some cases):\\n\\nmodel\\n\\nPhi3ForCausalLM( (model): Phi3Model( (embed_tokens): Embedding(32064, 3072, padding_idx=32000) (embed_dropout): Dropout(p=0.0, inplace=False) (layers): ModuleList( (0-31): 32 x Phi3DecoderLayer( (self_attn): Phi3Attention( (o_proj): Linear4bit(in_features=3072, out_features=3072, bias=False) <1> (qkv_proj): Linear4bit(in_features=3072, out_features=9216, bias=False) <1> (rotary_emb): Phi3RotaryEmbedding() ) (mlp): Phi3MLP( (gate_up_proj): Linear4bit(in_features=3072, out_features=16384, bias=False) <1> (down_proj): Linear4bit(in_features=8192, out_features=3072, bias=False) <1> (activation_fn): SiLU() ) (input_layernorm): Phi3RMSNorm((3072,), eps=1e-05) (resid_attn_dropout): Dropout(p=0.0, inplace=False) (resid_mlp_dropout): Dropout(p=0.0, inplace=False) (post_attention_layernorm): Phi3RMSNorm((3072,), eps=1e-05) ) ) (norm): Phi3RMSNorm((3072,), eps=1e-05) ) (lm_head): Linear(in_features=3072, out_features=32064, bias=False) )\\n\\n<1> Quantized layers\\n\\nA quantized model can be used directly for inference, but it cannot be trained any further. Those pesky Linear4bit layers take up much less space, which is the whole point of quantization; however, we cannot update them.\\n\\nWe need to add something else to our mix, a sprinkle of adapters.\\n\\nSetting Up Low-Rank Adapters (LoRA)\\n\\nLow-rank adapters can be attached to each and every one of the quantized layers. The adapters are mostly regular Linear layers that can be easily updated as usual. The clever trick in this case is that these adapters are significantly smaller than the layers that have been quantized.\\n\\nSince the quantized layers are frozen (they cannot be updated), setting up LoRA adapters on a quantized model drastically reduces the total number of trainable parameters to just 1% (or less) of its original size.\\n\\nWe can set up LoRA adapters in three easy steps:\\n\\nCall prepare_model_for_kbit_training() to improve numerical stability during training.\\n\\nCreate an instance of LoraConfig.\\n\\nApply the configuration to the quantized base model using the get_peft_model() method.\\n\\nLet\\'s try it out with our model:\\n\\nmodel = prepare_model_for_kbit_training(model) config = LoraConfig( # the rank of the adapter, the lower the fewer parameters you\\'ll need to train r=8, lora_alpha=16, # multiplier, usually 2*r bias=\"none\", lora_dropout=0.05, task_type=\"CAUSAL_LM\", # Newer models, such as Phi-3 at time of writing, may require # manually setting target modules target_modules=[\\'o_proj\\', \\'qkv_proj\\', \\'gate_up_proj\\', \\'down_proj\\'], ) model = get_peft_model(model, config) model\\n\\nPeftModelForCausalLM( (base_model): LoraModel( (model): Phi3ForCausalLM( (model): Phi3Model( (embed_tokens): Embedding(32064, 3072, padding_idx=32000) (embed_dropout): Dropout(p=0.0, inplace=False) (layers): ModuleList( (0-31): 32 x Phi3DecoderLayer( (self_attn): Phi3Attention( (o_proj): lora.Linear4bit( <1> (base_layer): Linear4bit(in_features=3072, out_features=3072, bias=False) (lora_dropout): ModuleDict((default): Dropout(p=0.05, inplace=False)) (lora_A): ModuleDict( (default): Linear(in_features=3072, out_features=8, bias=False) ) (lora_B): ModuleDict( (default): Linear(in_features=8, out_features=3072, bias=False) ) (lora_embedding_A): ParameterDict() (lora_embedding_B): ParameterDict() (lora_magnitude_vector): ModuleDict() ) (qkv_proj): lora.Linear4bit(...) <1> (rotary_emb): Phi3RotaryEmbedding() ) (mlp): Phi3MLP( (gate_up_proj): lora.Linear4bit(...) <1> (down_proj): lora.Linear4bit(...) <1> (activation_fn): SiLU() ) (input_layernorm): Phi3RMSNorm((3072,), eps=1e-05) (resid_attn_dropout): Dropout(p=0.0, inplace=False) (resid_mlp_dropout): Dropout(p=0.0, inplace=False) (post_attention_layernorm): Phi3RMSNorm((3072,), eps=1e-05) ) ) (norm): Phi3RMSNorm((3072,), eps=1e-05) ) (lm_head): Linear(in_features=3072, out_features=32064, bias=False) ) ) )\\n\\n<1> LoRA adapters\\n\\nThe output of the other three LoRA layers (qkv_proj, gate_up_proj, and down_proj) was suppressed to shorten the output.\\n\\nDid you get the following error? ValueError: Please specify `target_modules` in `peft_config` Most likely, you don\\'t need to specify the target_modules if you\\'re using one of the well-known models. The peft library takes care of it by automatically choosing the appropriate targets. However, there may be a gap between the time a popular model is released and the time the library gets updated. So, if you get the error above, look for the quantized layers in your model and list their names in the target_modules argument.\\n\\nThe quantized layers (Linear4bit) have turned into lora.Linear4bit modules where the quantized layer itself became the base_layer with some regular Linear layers (lora_A and lora_B) added to the mix.\\n\\nThese extra layers would make the model only slightly larger. However, the model preparation function (prepare_model_for_kbit_training()) turned every non-quantized layer to full precision (FP32), thus resulting in a 30% larger model:\\n\\nprint(model.get_memory_footprint()/1e6)\\n\\n2651.080704\\n\\nSince most parameters are frozen, only a tiny fraction of the total number of parameters are currently trainable, thanks to LoRA!\\n\\ntrain_p, tot_p = model.get_nb_trainable_parameters() print(f\\'Trainable parameters: {train_p/1e6:.2f}M\\') print(f\\'Total parameters: {tot_p/1e6:.2f}M\\') print(f\\'% of trainable parameters: {100*train_p/tot_p:.2f}%\\')\\n\\nTrainable parameters: 12.58M Total parameters: 3833.66M % of trainable parameters: 0.33%\\n\\nThe model is ready to be fine-tuned, but we are still missing one key component: our dataset.\\n\\nFormatting Your Dataset\\n\\n\"Like Yoda, speak, you must. Hrmmm.\" Master Yoda\\n\\nThe dataset yoda_sentences consists of 720 sentences translated from English to Yoda-speak. The dataset is hosted on the Hugging Face Hub and we can easily load it using the load_dataset() method from the Hugging Face datasets library:\\n\\ndataset = load_dataset(\"dvgodoy/yoda_sentences\", split=\"train\") dataset\\n\\nDataset({ features: [\\'sentence\\', \\'translation\\', \\'translation_extra\\'], num_rows: 720 })\\n\\nThe dataset has three columns:\\n\\noriginal English sentence (sentence)\\n\\nbasic translation to Yoda-speak (translation)\\n\\nenhanced translation including typical Yesss and Hrrmm interjections (translation_extra)\\n\\ndataset[0]\\n\\n{\\'sentence\\': \\'The birch canoe slid on the smooth planks.\\', \\'translation\\': \\'On the smooth planks, the birch canoe slid.\\', \\'translation_extra\\': \\'On the smooth planks, the birch canoe slid. Yes, hrrrm.\\'}\\n\\nThe SFTTrainer we\\'ll be using to fine-tune the model can automatically handle datasets in conversational format.\\n\\n{\"messages\":[ {\"role\": \"system\", \"content\": \"\"}, {\"role\": \"user\", \"content\": \"\"}, {\"role\": \"assistant\", \"content\": \"\"} ]}\\n\\nIMPORTANT UPDATE: unfortunately, in more recent versions of the trl library, the \"instruction\" format is not properly supported anymore, thus leading to the chat template not being applied to the dataset. In order to avoid this issue, we can convert the dataset to the \"conversational\" format.\\n\\nSo, we\\'ll convert the dataset to the conversational format using the format_dataset() function below:\\n\\n# Adapted from trl.extras.dataset_formatting.instructions_formatting_function # Converts dataset from prompt/completion format (not supported anymore) # to the conversational format def format_dataset(examples): if isinstance(examples[\"prompt\"], list): output_texts = [] for i in range(len(examples[\"prompt\"])): converted_sample = [ {\"role\": \"user\", \"content\": examples[\"prompt\"][i]}, {\"role\": \"assistant\", \"content\": examples[\"completion\"][i]}, ] output_texts.append(converted_sample) return {\\'messages\\': output_texts} else: converted_sample = [ {\"role\": \"user\", \"content\": examples[\"prompt\"]}, {\"role\": \"assistant\", \"content\": examples[\"completion\"]}, ] return {\\'messages\\': converted_sample}\\n\\ndataset = dataset.rename_column(\"sentence\", \"prompt\") dataset = dataset.rename_column(\"translation_extra\", \"completion\") dataset = dataset.map(format_dataset) dataset = dataset.remove_columns([\\'prompt\\', \\'completion\\', \\'translation\\']) messages = dataset[0][\\'messages\\'] messages\\n\\n[{\\'role\\': \\'user\\', \\'content\\': \\'The birch canoe slid on the smooth planks.\\'}, {\\'role\\': \\'assistant\\', \\'content\\': \\'On the smooth planks, the birch canoe slid. Yes, hrrrm.\\'}]\\n\\nTokenizer\\n\\nBefore moving into the actual training, we still need to load the tokenizer that corresponds to our model. The tokenizer is an important part of this process, determining how to convert text into tokens in the same way used to train the model.\\n\\nFor instruction/chat models, the tokenizer also contains its corresponding chat template that specifies:\\n\\nWhich special tokens should be used, and where they should be placed.\\n\\nWhere the system directives, user prompt, and model response should be placed.\\n\\nWhat is the generation prompt, that is, the special token that triggers the model\\'s response (more on that in the \"Querying the Model\" section)\\n\\nIMPORTANT UPDATE: due to changes in the default collator used by the SFTTrainer class while building the dataset, the EOS token (which is, in Phi-3, the same as the PAD token) was masked in the labels too thus leading to the model not being able to properly stop token generation.\\n\\nIn order to address this change, we can assign the UNK token to the PAD token, so the EOS token becomes unique and therefore not masked as part of the labels.\\n\\ntokenizer = AutoTokenizer.from_pretrained(repo_id) tokenizer.pad_token = tokenizer.unk_token tokenizer.pad_token_id = tokenizer.unk_token_id tokenizer.chat_template\\n\\n\"{% for message in messages %} {% if message[\\'role\\'] ## \\'system\\' %} {{\\'<|system|>\\\\n\\' + message[\\'content\\'] + \\'<|end|>\\\\n\\'}} {% elif message[\\'role\\'] ## \\'user\\' %} {{\\'<|user|>\\\\n\\' + message[\\'content\\'] + \\'<|end|>\\\\n\\'}} {% elif message[\\'role\\'] ## \\'assistant\\' %} {{\\'<|assistant|>\\\\n\\' + message[\\'content\\'] + \\'<|end|>\\\\n\\'}} {% endif %} {% endfor %} {% if add_generation_prompt %} {{ \\'<|assistant|>\\\\n\\' }}{% else %}{{ eos_token }} {% endif %}\"\\n\\nNever mind the seemingly overcomplicated template (I have added line breaks and indentation to it so it\\'s easier to read). It simply organizes the messages into a coherent block with the appropriate tags, as shown below (tokenize=False ensures we get readable text back instead of a numeric sequence of token IDs):\\n\\nprint(tokenizer.apply_chat_template(messages, tokenize=False))\\n\\n<|user|> The birch canoe slid on the smooth planks.<|end|> <|assistant|> On the smooth planks, the birch canoe slid. Yes, hrrrm.<|end|> <|endoftext|>\\n\\nNotice that each interaction is wrapped in either <|user|> or <|assistant|> tokens at the beginning and <|end|> at the end. Moreover, the <|endoftext|> token indicates the end of the whole block.\\n\\nDifferent models will have different templates and tokens to indicate the beginning and end of sentences and blocks.\\n\\nWe\\'re now ready to tackle the actual fine-tuning!\\n\\nFine-Tuning with SFTTrainer\\n\\nFine-tuning a model, whether large or otherwise, follows exactly the same training procedure as training a model from scratch. We could write our own training loop in pure PyTorch, or we could use Hugging Face\\'s Trainer to fine-tune our model.\\n\\nIt is much easier, however, to use SFTTrainer instead (which uses Trainer underneath, by the way), since it takes care of most of the nitty-gritty details for us, as long as we provide it with the following four arguments:\\n\\na model\\n\\na tokenizer\\n\\na dataset\\n\\na configuration object\\n\\nWe\\'ve already got the first three elements; let\\'s work on the last one.\\n\\nSFTConfig\\n\\nThere are many parameters that we can set in the configuration object. We have divided them into four groups:\\n\\nMemory usage optimization parameters related to gradient accumulation and checkpointing\\n\\nDataset-related arguments, such as the max_seq_length required by your data, and whether you are packing or not the sequences\\n\\nTypical training parameters such as the learning_rate and the num_train_epochs\\n\\nEnvironment and logging parameters such as output_dir (this will be the name of the model if you choose to push it to the Hugging Face Hub once it\\'s trained), logging_dir, and logging_steps.\\n\\nWhile the learning rate is a very important parameter (as a starting point, you can try the learning rate used to train the base model in the first place), it\\'s actually the maximum sequence length that\\'s more likely to cause out-of-memory issues.\\n\\nMake sure to always pick the shortest possible max_seq_length that makes sense for your use case. In ours, the sentences—both in English and Yoda-speak—are quite short, and a sequence of 64 tokens is more than enough to cover the prompt, the completion, and the added special tokens.\\n\\nFlash attention (which, unfortunately, isn\\'t supported in Colab), allows for more flexibility in working with longer sequences, avoiding the potential issue of OOM errors.\\n\\nIMPORTANT UPDATE: The release of trl version 0.20 brought several changes to the SFTConfig:\\n\\npacking is performed differently than it was, unless packing_strategy=\\'wrapped\\' is set;\\n\\nthe max_seq_length argument was renamed to max_length;\\n\\nthe bf16 defaults to True but, at the time of this update (Aug/2025), it didn\\'t check if the BF16 type was actually available or not, so it\\'s included in the configuration now.\\n\\nsft_config = SFTConfig( ## GROUP 1: Memory usage # These arguments will squeeze the most out of your GPU\\'s RAM # Checkpointing gradient_checkpointing=True, # this saves a LOT of memory # Set this to avoid exceptions in newer versions of PyTorch gradient_checkpointing_kwargs={\\'use_reentrant\\': False}, # Gradient Accumulation / Batch size # Actual batch (for updating) is same (1x) as micro-batch size gradient_accumulation_steps=1, # The initial (micro) batch size to start off with per_device_train_batch_size=16, # If batch size would cause OOM, halves its size until it works auto_find_batch_size=True, ## GROUP 2: Dataset-related max_length=64, # renamed in v0.20 # Dataset # packing a dataset means no padding is needed packing=True, packing_strategy=\\'wrapped\\', # added to approximate original packing behavior ## GROUP 3: These are typical training parameters num_train_epochs=10, learning_rate=3e-4, # Optimizer # 8-bit Adam optimizer - doesn\\'t help much if you\\'re using LoRA! optim=\\'paged_adamw_8bit\\', ## GROUP 4: Logging parameters logging_steps=10, logging_dir=\\'./logs\\', output_dir=\\'./phi3-mini-yoda-adapter\\', report_to=\\'none\\'. # ensures bf16 (the new default) is only used when it is actually available bf16=torch.cuda.is_bf16_supported(including_emulation=False) )\\n\\nSFTTrainer\\n\\n\"It is training time!\" The Hulk\\n\\nIMPORTANT UPDATE: The current version of trl (0.21) has a known issue where training fails if the LoRA configuration has already been applied to the model, as the trainer freezes the whole model, including the adapters.\\n\\nHowever, it works as expected when the configuration is passed as the peft_config argument to the trainer, since it is applied after freezing the existing layers.\\n\\nIf the model already contains the adapters, as in our case, training still works, but we need to use the underlying original model instead (model.base_model.model) to ensure the save_model() method functions correctly.\\n\\nWe can now finally create an instance of the supervised fine-tuning trainer:\\n\\ntrainer = SFTTrainer( model=model.base_model.model, # the underlying Phi-3 model peft_config=config, # added to fix issue in TRL>=0.20 processing_class=tokenizer, args=sft_config, train_dataset=dataset, )\\n\\nThe SFTTrainer had already preprocessed our dataset, so we can take a look inside and see how each mini-batch was assembled:\\n\\ndl = trainer.get_train_dataloader() batch = next(iter(dl))\\n\\nLet\\'s check the labels; after all, we didn\\'t provide any, did we?\\n\\nbatch[\\'input_ids\\'][0], batch[\\'labels\\'][0]\\n\\n(tensor([ 1746, 29892, 278, 10435, 3147, 698, 287, 29889, 32007, 32000, 32000, 32010, 10987, 278, 3252, 262, 1058, 380, 1772, 278, 282, 799, 29880, 18873, 1265, 29889, 32007, 32001, 11644, 380, 1772, 278, 282, 799, 29880, 18873, 1265, 29892, 1284, 278, 3252, 262, 29892, 366, 1818, 29889, 3869, 29892, 298, 21478, 1758, 29889, 32007, 32000, 32000, 32010, 315, 329, 278, 13793, 393, 7868, 29879, 278], device=\\'cuda:0\\'), tensor([ 1746, 29892, 278, 10435, 3147, 698, 287, 29889, 32007, 32000, 32000, 32010, 10987, 278, 3252, 262, 1058, 380, 1772, 278, 282, 799, 29880, 18873, 1265, 29889, 32007, 32001, 11644, 380, 1772, 278, 282, 799, 29880, 18873, 1265, 29892, 1284, 278, 3252, 262, 29892, 366, 1818, 29889, 3869, 29892, 298, 21478, 1758, 29889, 32007, 32000, 32000, 32010, 315, 329, 278, 13793, 393, 7868, 29879, 278], device=\\'cuda:0\\'))\\n\\nThe labels were added automatically, and they\\'re exactly the same as the inputs. Thus, this is a case of self-supervised fine-tuning.\\n\\nThe shifting of the labels will be handled automatically as well; there\\'s no need to be concerned about it.\\n\\nAlthough this is a 3.8 billion-parameter model, the configuration above allows us to squeeze training, using a mini-batch of eight, into an old setup with a consumer-grade GPU such as a GTX 1060 with only 6 GB RAM. True story! It takes about 35 minutes to complete the training process.\\n\\nNext, we call the train() method and wait:\\n\\ntrainer.train()\\n\\nStep Training Loss 10 2.990700 20 1.789500 30 1.581700 40 1.458300 50 1.362300 100 0.607900 150 0.353600 200 0.277500 220 0.252400\\n\\nQuerying the Model\\n\\nNow, our model should be able to produce a Yoda-like sentence as a response to any short sentence we give it.\\n\\nSo, the model requires its inputs to be properly formatted. We need to build a list of \"messages\"—ours, from the user, in this case—and prompt the model to answer by indicating it\\'s its turn to write.\\n\\nThis is the purpose of the add_generation_prompt argument: it adds <|assistant|> to the end of the conversation, so the model can predict the next word—and continue doing so until it predicts an <|endoftext|> token.\\n\\nThe helper function below assembles a message (in the conversational format) and applies the chat template to it, appending the generation prompt to its end.\\n\\ndef gen_prompt(tokenizer, sentence): converted_sample = [{\"role\": \"user\", \"content\": sentence}] prompt = tokenizer.apply_chat_template( converted_sample, tokenize=False, add_generation_prompt=True ) return prompt\\n\\nLet\\'s try generating a prompt for an example sentence:\\n\\nsentence = \\'The Force is strong in you!\\' prompt = gen_prompt(tokenizer, sentence) print(prompt)\\n\\n<|user|> The Force is strong in you!<|end|> <|assistant|>\\n\\nThe prompt seems about right; let\\'s use it to generate a completion. The helper function below does the following:\\n\\nIt tokenizes the prompt into a tensor of token IDs (add_special_tokens is set to False because the tokens were already added by the chat template).\\n\\nIt sets the model to evaluation mode.\\n\\nIt calls the model\\'s generate() method to produce the output (generated token IDs).\\n\\nIf the model was trained using mixed-precision, we wrap the generation in the autocast() context manager, which automatically handles conversion between data types.\\n\\nIt decodes the generated token IDs back into readable text.\\n\\ndef generate(model, tokenizer, prompt, max_new_tokens=64, skip_special_tokens=False): tokenized_input = tokenizer( prompt, add_special_tokens=False, return_tensors=\"pt\" ).to(model.device) model.eval() # if it was trained using mixed precision, uses autocast context ctx = torch.autocast(device_type=model.device.type, dtype=model.dtype) \\\\ if model.dtype in [torch.float16, torch.bfloat16] else nullcontext() with ctx: gen_output = model.generate(**tokenized_input, eos_token_id=tokenizer.eos_token_id, max_new_tokens=max_new_tokens) output = tokenizer.batch_decode(gen_output, skip_special_tokens=skip_special_tokens) return output[0]\\n\\nNow, we can finally try out our model and see if it\\'s indeed capable of generating Yoda-speak.\\n\\nprint(generate(model, tokenizer, prompt))\\n\\n<|user|> The Force is strong in you!<|end|><|assistant|> Strong in you, the Force is. Yes, hrrmmm.<|end|>\\n\\nAwesome! It works! Like Yoda, the model speaks. Hrrrmm.\\n\\nCongratulations, you\\'ve fine-tuned your first LLM!\\n\\nNow, you\\'ve got a small adapter that can be loaded into an instance of the Phi-3 Mini 4K Instruct model to turn it into a Yoda translator! How cool is that?\\n\\nSaving the Adapter\\n\\nOnce the training is completed, you can save the adapter (and the tokenizer) to disk by calling the trainer\\'s save_model() method. It will save everything to the specified folder:\\n\\ntrainer.save_model(\\'local-phi3-mini-yoda-adapter\\')\\n\\nThe files that were saved include:\\n\\nthe adapter configuration (adapter_config.json) and weights (adapter_model.safetensors)—the adapter itself is just 50 MB in size\\n\\nthe training arguments (training_args.bin)\\n\\nthe tokenizer (tokenizer.json and tokenizer.model), its configuration (tokenizer_config.json), and its special tokens (added_tokens.json and speciak_tokens_map.json)\\n\\na README file\\n\\nIf you\\'d like to share your adapter with everyone, you can also push it to the Hugging Face Hub. First, log in using a token that has permission to write:\\n\\nfrom huggingface_hub import login login()\\n\\nThe code above will ask you to enter an access token:\\n\\nA successful login should look like this (pay attention to the permissions):\\n\\nThen, you can use the trainer\\'s push_to_hub() method to upload everything to your account in the Hub. The model will be named after the output_dir argument of the training arguments:\\n\\ntrainer.push_to_hub()\\n\\nThere you go! Our model is out there in the world, and anyone can use it to translate English into Yoda speak.\\n\\nThat\\'s a wrap!\\n\\nDid you like this post?

You can think of this initial chapter as a recipe you can just follow. It\\'s a \"shoot first, ask questions later\" kind of post.\\n\\nYou\\'ll learn how to:\\n\\nLoad a quantized model using BitsAndBytes\\n\\nConfigure low-rank adapters (LoRA) using Hugging Face\\'s peft\\n\\nLoad and format a dataset\\n\\nFine-tune the model using the supervised fine-tuning trainer (SFTTrainer) from Hugging Face\\'s trl\\n\\nUse the fine-tuned model to generate a sentence\\n\\nJupyter Notebook\\n\\nThe Jupyter notebook corresponding to this post is part of the official Fine-Tuning LLMs repository on GitHub. You can also run it directly in Google Colab\\n\\nSetup\\n\\nIf you\\'re running it on Colab, you\\'ll need to pip install a few libraries: datasets, bitsandbytes, and trl.\\n\\nFor better reproducibility during training, however, use the pinned versions instead:\\n\\n#!pip install datasets bitsandbytes trl !pip install transformers==4.55.2 peft==0.17.0 accelerate==1.10.0 trl==0.21.0 bitsandbytes==0.47.0 datasets==4.0.0 huggingface-hub==0.34.4 safetensors==0.6.2 pandas==2.2.2 matplotlib==3.10.0 numpy==2.0.2\\n\\nImports\\n\\nFor the sake of organization, all libraries needed throughout the code used are imported at its very start. For this post, we\\'ll need the following imports:\\n\\nimport os import torch from datasets import load_dataset from peft import get_peft_model, LoraConfig, prepare_model_for_kbit_training from transformers import AutoModelForCausalLM, AutoTokenizer, BitsAndBytesConfig from trl import SFTConfig, SFTTrainer\\n\\nLoading a Quantized Base Model\\n\\nWe start by loading a quantized model, so it takes up less space in the GPU\\'s RAM. A quantized model replaces the original weights with approximate values that are represented by fewer bits. The simplest and most straightforward way to quantize a model is to turn its weights from 32-bit floating-point (FP32) numbers into 4-bit floating-point numbers (NF4). This simple yet powerful change already reduces the model\\'s memory footprint by roughly a factor of eight.\\n\\nWe can use an instance of BitsAndBytesConfig as the quantization_config argument while loading a model using the from_pretrained() method. To keep it flexible, so you can try it out with any other model of your choice, we\\'re using Hugging Face\\'s AutoModelForCausalLM. The repo you choose to use determines the model being loaded.\\n\\nWithout further ado, here\\'s our quantized model being loaded:\\n\\nbnb_config = BitsAndBytesConfig( load_in_4bit=True, bnb_4bit_quant_type=\"nf4\", bnb_4bit_use_double_quant=True, bnb_4bit_compute_dtype=torch.float32 ) repo_id = \\'microsoft/Phi-3-mini-4k-instruct\\' model = AutoModelForCausalLM.from_pretrained( repo_id, device_map=\"cuda:0\", quantization_config=bnb_config )\\n\\n\"The Phi-3-Mini-4K-Instruct is a 3.8B parameters, lightweight, state-of-the-art open model trained with the Phi-3 datasets that includes both synthetic data and the filtered publicly available websites data with a focus on high-quality and reasoning dense properties. The model belongs to the Phi-3 family with the Mini version in two variants 4K and 128K which is the context length (in tokens) that it can support.\" Source: Hugging Face Hub\\n\\nOnce the model is loaded, you can see how much space it occupies in memory using the get_memory_footprint() method.\\n\\nprint(model.get_memory_footprint()/1e6)\\n\\n2206.347264\\n\\nEven though it\\'s been quantized, the model still takes up a bit more than 2 gigabytes of RAM. The quantization procedure focuses on the linear layers within the Transformer decoder blocks (also referred to as \"layers\" in some cases):\\n\\nmodel\\n\\nPhi3ForCausalLM( (model): Phi3Model( (embed_tokens): Embedding(32064, 3072, padding_idx=32000) (embed_dropout): Dropout(p=0.0, inplace=False) (layers): ModuleList( (0-31): 32 x Phi3DecoderLayer( (self_attn): Phi3Attention( (o_proj): Linear4bit(in_features=3072, out_features=3072, bias=False) <1> (qkv_proj): Linear4bit(in_features=3072, out_features=9216, bias=False) <1> (rotary_emb): Phi3RotaryEmbedding() ) (mlp): Phi3MLP( (gate_up_proj): Linear4bit(in_features=3072, out_features=16384, bias=False) <1> (down_proj): Linear4bit(in_features=8192, out_features=3072, bias=False) <1> (activation_fn): SiLU() ) (input_layernorm): Phi3RMSNorm((3072,), eps=1e-05) (resid_attn_dropout): Dropout(p=0.0, inplace=False) (resid_mlp_dropout): Dropout(p=0.0, inplace=False) (post_attention_layernorm): Phi3RMSNorm((3072,), eps=1e-05) ) ) (norm): Phi3RMSNorm((3072,), eps=1e-05) ) (lm_head): Linear(in_features=3072, out_features=32064, bias=False) )\\n\\n<1> Quantized layers\\n\\nA quantized model can be used directly for inference, but it cannot be trained any further. Those pesky Linear4bit layers take up much less space, which is the whole point of quantization; however, we cannot update them.\\n\\nWe need to add something else to our mix, a sprinkle of adapters.\\n\\nSetting Up Low-Rank Adapters (LoRA)\\n\\nLow-rank adapters can be attached to each and every one of the quantized layers. The adapters are mostly regular Linear layers that can be easily updated as usual. The clever trick in this case is that these adapters are significantly smaller than the layers that have been quantized.\\n\\nSince the quantized layers are frozen (they cannot be updated), setting up LoRA adapters on a quantized model drastically reduces the total number of trainable parameters to just 1% (or less) of its original size.\\n\\nWe can set up LoRA adapters in three easy steps:\\n\\nCall prepare_model_for_kbit_training() to improve numerical stability during training.\\n\\nCreate an instance of LoraConfig.\\n\\nApply the configuration to the quantized base model using the get_peft_model() method.\\n\\nLet\\'s try it out with our model:\\n\\nmodel = prepare_model_for_kbit_training(model) config = LoraConfig( # the rank of the adapter, the lower the fewer parameters you\\'ll need to train r=8, lora_alpha=16, # multiplier, usually 2*r bias=\"none\", lora_dropout=0.05, task_type=\"CAUSAL_LM\", # Newer models, such as Phi-3 at time of writing, may require # manually setting target modules target_modules=[\\'o_proj\\', \\'qkv_proj\\', \\'gate_up_proj\\', \\'down_proj\\'], ) model = get_peft_model(model, config) model\\n\\nPeftModelForCausalLM( (base_model): LoraModel( (model): Phi3ForCausalLM( (model): Phi3Model( (embed_tokens): Embedding(32064, 3072, padding_idx=32000) (embed_dropout): Dropout(p=0.0, inplace=False) (layers): ModuleList( (0-31): 32 x Phi3DecoderLayer( (self_attn): Phi3Attention( (o_proj): lora.Linear4bit( <1> (base_layer): Linear4bit(in_features=3072, out_features=3072, bias=False) (lora_dropout): ModuleDict((default): Dropout(p=0.05, inplace=False)) (lora_A): ModuleDict( (default): Linear(in_features=3072, out_features=8, bias=False) ) (lora_B): ModuleDict( (default): Linear(in_features=8, out_features=3072, bias=False) ) (lora_embedding_A): ParameterDict() (lora_embedding_B): ParameterDict() (lora_magnitude_vector): ModuleDict() ) (qkv_proj): lora.Linear4bit(...) <1> (rotary_emb): Phi3RotaryEmbedding() ) (mlp): Phi3MLP( (gate_up_proj): lora.Linear4bit(...) <1> (down_proj): lora.Linear4bit(...) <1> (activation_fn): SiLU() ) (input_layernorm): Phi3RMSNorm((3072,), eps=1e-05) (resid_attn_dropout): Dropout(p=0.0, inplace=False) (resid_mlp_dropout): Dropout(p=0.0, inplace=False) (post_attention_layernorm): Phi3RMSNorm((3072,), eps=1e-05) ) ) (norm): Phi3RMSNorm((3072,), eps=1e-05) ) (lm_head): Linear(in_features=3072, out_features=32064, bias=False) ) ) )\\n\\n<1> LoRA adapters\\n\\nThe output of the other three LoRA layers (qkv_proj, gate_up_proj, and down_proj) was suppressed to shorten the output.\\n\\nDid you get the following error? ValueError: Please specify `target_modules` in `peft_config` Most likely, you don\\'t need to specify the target_modules if you\\'re using one of the well-known models. The peft library takes care of it by automatically choosing the appropriate targets. However, there may be a gap between the time a popular model is released and the time the library gets updated. So, if you get the error above, look for the quantized layers in your model and list their names in the target_modules argument.\\n\\nThe quantized layers (Linear4bit) have turned into lora.Linear4bit modules where the quantized layer itself became the base_layer with some regular Linear layers (lora_A and lora_B) added to the mix.\\n\\nThese extra layers would make the model only slightly larger. However, the model preparation function (prepare_model_for_kbit_training()) turned every non-quantized layer to full precision (FP32), thus resulting in a 30% larger model:\\n\\nprint(model.get_memory_footprint()/1e6)\\n\\n2651.080704\\n\\nSince most parameters are frozen, only a tiny fraction of the total number of parameters are currently trainable, thanks to LoRA!\\n\\ntrain_p, tot_p = model.get_nb_trainable_parameters() print(f\\'Trainable parameters: {train_p/1e6:.2f}M\\') print(f\\'Total parameters: {tot_p/1e6:.2f}M\\') print(f\\'% of trainable parameters: {100*train_p/tot_p:.2f}%\\')\\n\\nTrainable parameters: 12.58M Total parameters: 3833.66M % of trainable parameters: 0.33%\\n\\nThe model is ready to be fine-tuned, but we are still missing one key component: our dataset.\\n\\nFormatting Your Dataset\\n\\n\"Like Yoda, speak, you must. Hrmmm.\" Master Yoda\\n\\nThe dataset yoda_sentences consists of 720 sentences translated from English to Yoda-speak. The dataset is hosted on the Hugging Face Hub and we can easily load it using the load_dataset() method from the Hugging Face datasets library:\\n\\ndataset = load_dataset(\"dvgodoy/yoda_sentences\", split=\"train\") dataset\\n\\nDataset({ features: [\\'sentence\\', \\'translation\\', \\'translation_extra\\'], num_rows: 720 })\\n\\nThe dataset has three columns:\\n\\noriginal English sentence (sentence)\\n\\nbasic translation to Yoda-speak (translation)\\n\\nenhanced translation including typical Yesss and Hrrmm interjections (translation_extra)\\n\\ndataset[0]\\n\\n{\\'sentence\\': \\'The birch canoe slid on the smooth planks.\\', \\'translation\\': \\'On the smooth planks, the birch canoe slid.\\', \\'translation_extra\\': \\'On the smooth planks, the birch canoe slid.

In order to avoid this issue, we can convert the dataset to the \"conversational\" format.\\n\\nSo, we\\'ll convert the dataset to the conversational format using the format_dataset() function below:\\n\\n# Adapted from trl.extras.dataset_formatting.instructions_formatting_function # Converts dataset from prompt/completion format (not supported anymore) # to the conversational format def format_dataset(examples): if isinstance(examples[\"prompt\"], list): output_texts = [] for i in range(len(examples[\"prompt\"])): converted_sample = [ {\"role\": \"user\", \"content\": examples[\"prompt\"][i]}, {\"role\": \"assistant\", \"content\": examples[\"completion\"][i]}, ] output_texts.append(converted_sample) return {\\'messages\\': output_texts} else: converted_sample = [ {\"role\": \"user\", \"content\": examples[\"prompt\"]}, {\"role\": \"assistant\", \"content\": examples[\"completion\"]}, ] return {\\'messages\\': converted_sample}\\n\\ndataset = dataset.rename_column(\"sentence\", \"prompt\") dataset = dataset.rename_column(\"translation_extra\", \"completion\") dataset = dataset.map(format_dataset) dataset = dataset.remove_columns([\\'prompt\\', \\'completion\\', \\'translation\\']) messages = dataset[0][\\'messages\\'] messages\\n\\n[{\\'role\\': \\'user\\', \\'content\\': \\'The birch canoe slid on the smooth planks.\\'}, {\\'role\\': \\'assistant\\', \\'content\\': \\'On the smooth planks, the birch canoe slid. Yes, hrrrm.\\'}]\\n\\nTokenizer\\n\\nBefore moving into the actual training, we still need to load the tokenizer that corresponds to our model. The tokenizer is an important part of this process, determining how to convert text into tokens in the same way used to train the model.\\n\\nFor instruction/chat models, the tokenizer also contains its corresponding chat template that specifies:\\n\\nWhich special tokens should be used, and where they should be placed.\\n\\nWhere the system directives, user prompt, and model response should be placed.\\n\\nWhat is the generation prompt, that is, the special token that triggers the model\\'s response (more on that in the \"Querying the Model\" section)\\n\\nIMPORTANT UPDATE: due to changes in the default collator used by the SFTTrainer class while building the dataset, the EOS token (which is, in Phi-3, the same as the PAD token) was masked in the labels too thus leading to the model not being able to properly stop token generation.\\n\\nIn order to address this change, we can assign the UNK token to the PAD token, so the EOS token becomes unique and therefore not masked as part of the labels.\\n\\ntokenizer = AutoTokenizer.from_pretrained(repo_id) tokenizer.pad_token = tokenizer.unk_token tokenizer.pad_token_id = tokenizer.unk_token_id tokenizer.chat_template\\n\\n\"{% for message in messages %} {% if message[\\'role\\'] ## \\'system\\' %} {{\\'<|system|>\\\\n\\' + message[\\'content\\'] + \\'<|end|>\\\\n\\'}} {% elif message[\\'role\\'] ## \\'user\\' %} {{\\'<|user|>\\\\n\\' + message[\\'content\\'] + \\'<|end|>\\\\n\\'}} {% elif message[\\'role\\'] ## \\'assistant\\' %} {{\\'<|assistant|>\\\\n\\' + message[\\'content\\'] + \\'<|end|>\\\\n\\'}} {% endif %} {% endfor %} {% if add_generation_prompt %} {{ \\'<|assistant|>\\\\n\\' }}{% else %}{{ eos_token }} {% endif %}\"\\n\\nNever mind the seemingly overcomplicated template (I have added line breaks and indentation to it so it\\'s easier to read). It simply organizes the messages into a coherent block with the appropriate tags, as shown below (tokenize=False ensures we get readable text back instead of a numeric sequence of token IDs):\\n\\nprint(tokenizer.apply_chat_template(messages, tokenize=False))\\n\\n<|user|> The birch canoe slid on the smooth planks.<|end|> <|assistant|> On the smooth planks, the birch canoe slid. Yes, hrrrm.<|end|> <|endoftext|>\\n\\nNotice that each interaction is wrapped in either <|user|> or <|assistant|> tokens at the beginning and <|end|> at the end. Moreover, the <|endoftext|> token indicates the end of the whole block.\\n\\nDifferent models will have different templates and tokens to indicate the beginning and end of sentences and blocks.\\n\\nWe\\'re now ready to tackle the actual fine-tuning!\\n\\nFine-Tuning with SFTTrainer\\n\\nFine-tuning a model, whether large or otherwise, follows exactly the same training procedure as training a model from scratch. We could write our own training loop in pure PyTorch, or we could use Hugging Face\\'s Trainer to fine-tune our model.\\n\\nIt is much easier, however, to use SFTTrainer instead (which uses Trainer underneath, by the way), since it takes care of most of the nitty-gritty details for us, as long as we provide it with the following four arguments:\\n\\na model\\n\\na tokenizer\\n\\na dataset\\n\\na configuration object\\n\\nWe\\'ve already got the first three elements; let\\'s work on the last one.\\n\\nSFTConfig\\n\\nThere are many parameters that we can set in the configuration object. We have divided them into four groups:\\n\\nMemory usage optimization parameters related to gradient accumulation and checkpointing\\n\\nDataset-related arguments, such as the max_seq_length required by your data, and whether you are packing or not the sequences\\n\\nTypical training parameters such as the learning_rate and the num_train_epochs\\n\\nEnvironment and logging parameters such as output_dir (this will be the name of the model if you choose to push it to the Hugging Face Hub once it\\'s trained), logging_dir, and logging_steps.\\n\\nWhile the learning rate is a very important parameter (as a starting point, you can try the learning rate used to train the base model in the first place), it\\'s actually the maximum sequence length that\\'s more likely to cause out-of-memory issues.\\n\\nMake sure to always pick the shortest possible max_seq_length that makes sense for your use case. In ours, the sentences—both in English and Yoda-speak—are quite short, and a sequence of 64 tokens is more than enough to cover the prompt, the completion, and the added special tokens.\\n\\nFlash attention (which, unfortunately, isn\\'t supported in Colab), allows for more flexibility in working with longer sequences, avoiding the potential issue of OOM errors.\\n\\nIMPORTANT UPDATE: The release of trl version 0.20 brought several changes to the SFTConfig:\\n\\npacking is performed differently than it was, unless packing_strategy=\\'wrapped\\' is set;\\n\\nthe max_seq_length argument was renamed to max_length;\\n\\nthe bf16 defaults to True but, at the time of this update (Aug/2025), it didn\\'t check if the BF16 type was actually available or not, so it\\'s included in the configuration now.\\n\\nsft_config = SFTConfig( ## GROUP 1: Memory usage # These arguments will squeeze the most out of your GPU\\'s RAM # Checkpointing gradient_checkpointing=True, # this saves a LOT of memory # Set this to avoid exceptions in newer versions of PyTorch gradient_checkpointing_kwargs={\\'use_reentrant\\': False}, # Gradient Accumulation / Batch size # Actual batch (for updating) is same (1x) as micro-batch size gradient_accumulation_steps=1, # The initial (micro) batch size to start off with per_device_train_batch_size=16, # If batch size would cause OOM, halves its size until it works auto_find_batch_size=True, ## GROUP 2: Dataset-related max_length=64, # renamed in v0.20 # Dataset # packing a dataset means no padding is needed packing=True, packing_strategy=\\'wrapped\\', # added to approximate original packing behavior ## GROUP 3: These are typical training parameters num_train_epochs=10, learning_rate=3e-4, # Optimizer # 8-bit Adam optimizer - doesn\\'t help much if you\\'re using LoRA! optim=\\'paged_adamw_8bit\\', ## GROUP 4: Logging parameters logging_steps=10, logging_dir=\\'./logs\\', output_dir=\\'./phi3-mini-yoda-adapter\\', report_to=\\'none\\'. # ensures bf16 (the new default) is only used when it is actually available bf16=torch.cuda.is_bf16_supported(including_emulation=False) )\\n\\nSFTTrainer\\n\\n\"It is training time!\" The Hulk\\n\\nIMPORTANT UPDATE: The current version of trl (0.21) has a known issue where training fails if the LoRA configuration has already been applied to the model, as the trainer freezes the whole model, including the adapters.\\n\\nHowever, it works as expected when the configuration is passed as the peft_config argument to the trainer, since it is applied after freezing the existing layers.\\n\\nIf the model already contains the adapters, as in our case, training still works, but we need to use the underlying original model instead (model.base_model.model) to ensure the save_model() method functions correctly.\\n\\nWe can now finally create an instance of the supervised fine-tuning trainer:\\n\\ntrainer = SFTTrainer( model=model.base_model.model, # the underlying Phi-3 model peft_config=config, # added to fix issue in TRL>=0.20 processing_class=tokenizer, args=sft_config, train_dataset=dataset, )\\n\\nThe SFTTrainer had already preprocessed our dataset, so we can take a look inside and see how each mini-batch was assembled:\\n\\ndl = trainer.get_train_dataloader() batch = next(iter(dl))\\n\\nLet\\'s check the labels; after all, we didn\\'t provide any, did we?\\n\\nbatch[\\'input_ids\\'][0], batch[\\'labels\\'][0]\\n\\n(tensor([ 1746, 29892, 278, 10435, 3147, 698, 287, 29889, 32007, 32000, 32000, 32010, 10987, 278, 3252, 262, 1058, 380, 1772, 278, 282, 799, 29880, 18873, 1265, 29889, 32007, 32001, 11644, 380, 1772, 278, 282, 799, 29880, 18873, 1265, 29892, 1284, 278, 3252, 262, 29892, 366, 1818, 29889, 3869, 29892, 298, 21478, 1758, 29889, 32007, 32000, 32000, 32010, 315, 329, 278, 13793, 393, 7868, 29879, 278], device=\\'cuda:0\\'), tensor([ 1746, 29892, 278, 10435, 3147, 698, 287, 29889, 32007, 32000, 32000, 32010, 10987, 278, 3252, 262, 1058, 380, 1772, 278, 282, 799, 29880, 18873, 1265, 29889, 32007, 32001, 11644, 380, 1772, 278, 282, 799, 29880, 18873, 1265, 29892, 1284, 278, 3252, 262, 29892, 366, 1818, 29889, 3869, 29892, 298, 21478, 1758, 29889, 32007, 32000, 32000, 32010, 315, 329, 278, 13793, 393, 7868, 29879, 278], device=\\'cuda:0\\'))\\n\\nThe labels were added automatically, and they\\'re exactly the same as the inputs. Thus, this is a case of self-supervised fine-tuning.\\n\\nThe shifting of the labels will be handled automatically as well; there\\'s no need to be concerned about it.\\n\\nAlthough this is a 3.8 billion-parameter model, the configuration above allows us to squeeze training, using a mini-batch of eight, into an old setup with a consumer-grade GPU such as a GTX 1060 with only 6 GB RAM. True story! It takes about 35 minutes to complete the training process.\\n\\nNext, we call the train() method and wait:\\n\\ntrainer.train()\\n\\nStep Training Loss 10 2.990700 20 1.789500 30 1.581700 40 1.458300 50 1.362300 100 0.607900 150 0.353600 200 0.277500 220 0.252400\\n\\nQuerying the Model\\n\\nNow, our model should be able to produce a Yoda-like sentence as a response to any short sentence we give it.\\n\\nSo, the model requires its inputs to be properly formatted. We need to build a list of \"messages\"—ours, from the user, in this case—and prompt the model to answer by indicating it\\'s its turn to write.\\n\\nThis is the purpose of the add_generation_prompt argument: it adds <|assistant|> to the end of the conversation, so the model can predict the next word—and continue doing so until it predicts an <|endoftext|> token.\\n\\nThe helper function below assembles a message (in the conversational format) and applies the chat template to it, appending the generation prompt to its end.\\n\\ndef gen_prompt(tokenizer, sentence): converted_sample = [{\"role\": \"user\", \"content\": sentence}] prompt = tokenizer.apply_chat_template( converted_sample, tokenize=False, add_generation_prompt=True ) return prompt\\n\\nLet\\'s try generating a prompt for an example sentence:\\n\\nsentence = \\'The Force is strong in you!\\' prompt = gen_prompt(tokenizer, sentence) print(prompt)\\n\\n<|user|> The Force is strong in you!<|end|> <|assistant|>\\n\\nThe prompt seems about right; let\\'s use it to generate a completion. The helper function below does the following:\\n\\nIt tokenizes the prompt into a tensor of token IDs (add_special_tokens is set to False because the tokens were already added by the chat template).\\n\\nIt sets the model to evaluation mode.\\n\\nIt calls the model\\'s generate() method to produce the output (generated token IDs).\\n\\nIf the model was trained using mixed-precision, we wrap the generation in the autocast() context manager, which automatically handles conversion between data types.\\n\\nIt decodes the generated token IDs back into readable text.\\n\\ndef generate(model, tokenizer, prompt, max_new_tokens=64, skip_special_tokens=False): tokenized_input = tokenizer( prompt, add_special_tokens=False, return_tensors=\"pt\" ).to(model.device) model.eval() # if it was trained using mixed precision, uses autocast context ctx = torch.autocast(device_type=model.device.type, dtype=model.dtype) \\\\ if model.dtype in [torch.float16, torch.bfloat16] else nullcontext() with ctx: gen_output = model.generate(**tokenized_input, eos_token_id=tokenizer.eos_token_id, max_new_tokens=max_new_tokens) output = tokenizer.batch_decode(gen_output, skip_special_tokens=skip_special_tokens) return output[0]\\n\\nNow, we can finally try out our model and see if it\\'s indeed capable of generating Yoda-speak.\\n\\nprint(generate(model, tokenizer, prompt))\\n\\n<|user|> The Force is strong in you!<|end|><|assistant|> Strong in you, the Force is. Yes, hrrmmm.<|end|>\\n\\nAwesome! It works! Like Yoda, the model speaks. Hrrrmm.\\n\\nCongratulations, you\\'ve fine-tuned your first LLM!\\n\\nNow, you\\'ve got a small adapter that can be loaded into an instance of the Phi-3 Mini 4K Instruct model to turn it into a Yoda translator! How cool is that?\\n\\nSaving the Adapter\\n\\nOnce the training is completed, you can save the adapter (and the tokenizer) to disk by calling the trainer\\'s save_model() method. It will save everything to the specified folder:\\n\\ntrainer.save_model(\\'local-phi3-mini-yoda-adapter\\')\\n\\nThe files that were saved include:\\n\\nthe adapter configuration (adapter_config.json) and weights (adapter_model.safetensors)—the adapter itself is just 50 MB in size\\n\\nthe training arguments (training_args.bin)\\n\\nthe tokenizer (tokenizer.json and tokenizer.model), its configuration (tokenizer_config.json), and its special tokens (added_tokens.json and speciak_tokens_map.json)\\n\\na README file\\n\\nIf you\\'d like to share your adapter with everyone, you can also push it to the Hugging Face Hub. First, log in using a token that has permission to write:\\n\\nfrom huggingface_hub import login login()\\n\\nThe code above will ask you to enter an access token:\\n\\nA successful login should look like this (pay attention to the permissions):\\n\\nThen, you can use the trainer\\'s push_to_hub() method to upload everything to your account in the Hub. The model will be named after the output_dir argument of the training arguments:\\n\\ntrainer.push_to_hub()\\n\\nThere you go!

Apple's Neural Engine, a custom AI accelerator, enhances on-device performance by being 12x more power-efficient than CPUs and 4x more than GPUs. However, the Neural Engine is only accessible via Apple's closed-source Core ML framework, which poses challenges for developers converting models from PyTorch. To address this, Apple offers MLX, a flexible ML framework targeting GPUs, which can be used alongside Core ML. The article outlines a conversion process for dots.ocr using CoreML and MLX, demonstrating the potential for broader application in on-device model deployment.

Pri- mary tools of computer vision, such as deep learning, have started to demand unreasonable and hard-to-satisfy GPU resources when classical computation is concerned. Neural architectures in many areas of CV are becoming increasingly larger, parameter-heavy and require more and more time to converge during training. Moreover, many CV problems contain combinatorial objectives that cannot be solved by an exhaustive search in a reasonable time. As a consequence, they require hardware that is able to fulfil high data pro- cessing demands (e.g. graphical processing units (GPUs)).\\n\\nevolving quantum systems into distinct states using quan- tum mechanical effects. To harness these effects for prac- tical computation, two primary paradigms, governed by two physical principles, have emerged: Adiabatic Quantum Computing (AQC) [11], [15] and gate-based quantum com- puting [10], [16]. AQC relies on the smooth evolution or annealing of a so-called Hamiltonian to guide the system toward its lowest-energy state, making it naturally suited for optimisation problems, particularly those expressed in the Quadratic Unconstrained Binary Optimisation (QUBO) form. In contrast, gate-based quantum computing employs discrete unitary transformations, offering greater flexibility in algorithm design. Together, these paradigms define mod- ern quantum computation, each with distinct advantages that depend on the specific problem domain.\\n\\nBroadly speaking, Quantum Computing (QC) allows designing algorithms to solve several classes of computa- tionally challenging problems with possible computational gains depending on the type of QC and the problem. The type of computational gains can range from improvements in asymptotic complexity (compared to the best classical counterparts) [17] to the acceleration of computations in absolute terms (in the same complexity class) [18]. Quantum computers operate on qubits, counterparts of classical bits that leverage quantum effects. These qubits abstractly span a Hilbert space, where computation takes place. In theory, a quantum computer can perform everything a classical com- puter can perform and vice versa. However, the correspond- ing Hilbert space of multiple qubits is exponentially large (2n-dimensional for n qubits), due to the tensor product structure of quantum mechanics, and so-called entangled states where the qubits cannot be described separately. Classical computation of the corresponding exponentially large operators would, of course, be highly time-consuming.\\n\\nAs of 2023-2025, we observe a transition in the field thanks to the proliferation of real quantum hardware: If previously (pre-2015), quantum hardware was accessible predominantly to researchers developing it, multiple quan- tum and quantum-inspired computers (e.g. adiabatic, gate- based machines, photonic machines, quantum simulators and quantum-inspired optimisers) can nowadays be ac- cessed by researchers from different fields, and the devel- oped methods can be tested on real quantum hardware. This is in contrast to the vast majority of papers on quantum algorithms published before, including highly influential ones that have been tested on very small problems on real quantum hardware so far [19], [20], [21]. For the next two decades, experts predict a super-linear increase in the number of qubits [22] and substantial improvements in the properties of the individual qubits (such as their decoher- ence and connectivity properties). We argue that these pre- dictions should be taken seriously, because the investments in quantum computing and algorithm development are sub- stantial; many national and international initiatives related to quantum computing were brought into being within the last several years. Quantum computing power on selected algorithms scales super-linearly (up to exponentially) with the number of qubits. Almost all the big technology com- panies including Intel, IBM, Google, Microsoft, Amazon, NVIDIA and D-Wave are aiming at a steady increase in the number of qubits and are investing heavily in quantum\\n\\ntechnology, as the limits of Moore’s law is approached1.

Not many problems in computer vision can be formulated in a form consumable by modern quantum hardware. The estimated number of qubits necessary for practical computer vision problems with gate quantum computing formulations that\\n\\nmake use of provably advantageous quantum algorithms is typically larger than available on NISQ architectures. It is rare that QUBO forms are available and can be directly tested on an AQC. Often, it is the case that the target problem first has to be mapped to QUBO, and the solution has to be encoded in binary form. It is, therefore, of broad scientific interest that computer vision (and machine learn- ing) problems can be formulated for quantum computing and efficiently solved with it, while offering advantages compared to their classical method counterparts. Moreover, using a quantum mindset to CV problems can provide a new perspective, leading to new insights for classical CV and new methods, especially for the field in which many things are empirical. We discuss these aspects in Sec. 3. Related Research Fields. Several research fields related to QeCV can be identified in the literature, such as quantum-inspired computer vision, Quantum Image Pro- cessing (QIP), and Quantum Machine Learning (QML).\\n\\nThe first category simulates quantum-mechanical effects or draws inspiration from quantum mechanics [41], [42], [43], [44], [45]. These algorithms are not meant for execution on quantum hardware and are solely inspired by quantum phenomena. They should not be confused with techniques that can execute on quantum hardware. The second method category, i.e. QIP, is a field of quantum information pro- cessing focusing on representing and processing images as quantum states [46], [47], [48]. QIP provides several faster algorithms (in theory) for multiple widely-used linear alge- bra operations and common low-level operations on images [49], [50], [51].\\n\\nBoth method categories above can be broadly seen as sub-fields of QeCV, though distinct from this survey’s focus on mid- and high-level computer vision tasks (e.g. point set or mesh alignment, object tracking, and robust fitting). In contrast, just as classical ML is deeply intertwined with CV, quantum machine learning [52], [53], [54] explores the intersection of quantum computing and machine learning to enhance learning algorithms. It holds promise for QeCV, potentially accelerating tasks such as image classification, object detection, and pattern recognition. However, current QML methods remain largely theoretical, with limited prac- tical applications due to quantum hardware and scalability constraints. Hence, QML remains distant from this survey’s focus on practical applications to CV.\\n\\n1.2 Motivation and Scope of this Survey\\n\\nIn the broad sense, this survey shows by reviewing the first works in the field, how quantum computations and quantum hardware can be leveraged for computer vision. It showcases recent and ongoing progress towards practical quantum computing and computer vision, discusses the current state of the art, limitations therein, expected progress and its impact on computer vision. Our goal is to provide a shared, computer-science-friendly language and mathematical for- mulation of quantum computing, covering its two modern paradigms, i.e. gate-based quantum computing and adia- batic quantum computation. We identify and classify com- puter vision problems that can be addressed by quantum computers and analyse what they do have in common.\\n\\nWe observe that the quantum technology acts more and more like a booster for algorithm development in CV. The\\n\\nfact that the developed methods could run on real quantum hardware often brings us to interesting discoveries. Thus, we can often obtain methods that work better than existing classical ones.\\n\\nThere are several considerations regarding the gate- based model vs adiabatic model. Gate-based QCs are cur- rently severely limited in the number of qubits, their con- nectivity patterns and the accuracy of operations (gates) that can be applied to the qubits. Additionally, decoher- ence poses a significant obstacle. Thus, the largest num- ber factorised on gate-based quantum hardware using the celebrated Shor’s algorithm remains 21 for more than ten years as of the moment of writing [55], [56]. In contrast, the number of qubits in modern quantum annealers such as D- Wave is larger, which in combination with their connectivity and qubit characteristics allows for solving combinatorial optimisation problems in the Ising encodings of sizes rele- vant to computer vision and real-world applications. Also, qubit coherence times required for AQC are shorter than for gate-based machines, which partially explains the better scalability of quantum annealers compared to gate-based machines. Hence, the interest in especially applying AQC in computer vision has grown substantially over the last three years.\\n\\nThis survey focuses on computer vision methods for gate-based quantum computers and quantum annealers that have been evaluated on real quantum hardware (in the case of adiabatic quantum annealers) or simulators of gate-based quantum computers. We include a few theoretical works on gate-based quantum computing in computer vision without experiments on a simulator though this survey is gener- ally structured to reflect the applied focus of QeCV. Since computer vision is an applied science, we believe that the criterion of experimentation on quantum hardware is piv- otal, especially because modern quantum machines already allow solving problems of sizes encountered in practical applications. That is why we believe it is important that the methods are evaluated and the exposition is not restricted to theoretical considerations.\\n\\nPaper Selection Criteria. QeCV is a nascent field. In line with its aspirational definition, this survey presents an overview of methods designed for full or hybrid execution (i.e. classical-quantum) on quantum hardware, emphasising approaches that report theoretically grounded results with potential relevance to QeCV. Hence, the main paper selec- tion criterion for this survey is experimental evaluation of the proposed techniques and, at least, some results obtained on real quantum hardware. Moreover, we focus on works published at computer vision conferences (CVPR, ICCV and ECCV) and other venues (perhaps interdisciplinary) that are interested in the application of quantum computers in vision. We also include several technical reports on arXiv.org if they fulfil the main paper selection criterion. The authors made efforts to provide as complete review of the field as possible, but cannot claim completeness in every aspect, since the field is getting momentum and growing. We also recommend interested readers to read the discussed papers for more details.\\n\\nRelated Surveys.

Recently, Quantum Machine Learning (QML) has gained significant attention as it is now a fast- growing area. The large body of works in the QML space has\\n\\nbeen reviewed in [57], [58], whereas [57], [59], [60] also focus on quantum approaches for tackling optimisation problems. Out of all machine learning models, quantum deep learning requires special attention due to the impact of these learning machines in the field of AI. Massoli et al. [61] gather, compare and analyse the current state-of-the-art concerning Quantum Neural Networks (QNN). Yarkoni et al. [62], on the other hand, look into possible industry applications of Quantum Annealing (QA); their survey is perhaps closest to our work in terms of focusing on an application area of QA.\\n\\nMohseni et al. [18] review different methods for solv- ing Ising problems (exactly or approximately) and discuss quantum annealing as one meta-heuristic. A few surveys focus on quantum annealing for physicists [63], whereas our work is written for researchers with a computer vision back- ground. The short survey by Larasati et al. [64] provides a summary of a few quantum computer vision methods (<5% of what we cover) and is much less comprehensive than our article. Another brief paper by Mebtouche et al. [65] reviews the foundations of quantum computing, machine learning and multiple low-level vision and image processing tech- niques. In this regard, ours is the first comprehensive survey of its kind with an emphasis on QeCV.\\n\\nTarget Audience. This survey it is written for applied com- puter scientists, especially computer vision researchers and practitioners, who may have little to no background in theoretical physics. Unlike previous surveys [18], [57], [58], [59], [60], [61], [65] on quantum algorithms, mostly published outside traditional computer vision venues, our goal is to make QeCV accessible and actionable for a broader audience of computer vision researchers and engineers. By consolidating multiple contributions, we aim to bridge that gap and provide a comprehensive overview of existing QeCV methods, along with insights into future directions.\\n\\nWe present a practical “cookbook” for computer vision practitioners to begin exploring quantum-enhanced tech- niques today and to prepare for the growing impact of quan- tum technologies.

Out of all machine learning models, quantum deep learning requires special attention due to the impact of these learning machines in the field of AI. Massoli et al. [61] gather, compare and analyse the current state-of-the-art concerning Quantum Neural Networks (QNN). Yarkoni et al. [62], on the other hand, look into possible industry applications of Quantum Annealing (QA); their survey is perhaps closest to our work in terms of focusing on an application area of QA.\\n\\nMohseni et al. [18] review different methods for solv- ing Ising problems (exactly or approximately) and discuss quantum annealing as one meta-heuristic. A few surveys focus on quantum annealing for physicists [63], whereas our work is written for researchers with a computer vision back- ground. The short survey by Larasati et al. [64] provides a summary of a few quantum computer vision methods (<5% of what we cover) and is much less comprehensive than our article. Another brief paper by Mebtouche et al. [65] reviews the foundations of quantum computing, machine learning and multiple low-level vision and image processing tech- niques. In this regard, ours is the first comprehensive survey of its kind with an emphasis on QeCV.\\n\\nTarget Audience. This survey it is written for applied com- puter scientists, especially computer vision researchers and practitioners, who may have little to no background in theoretical physics. Unlike previous surveys [18], [57], [58], [59], [60], [61], [65] on quantum algorithms, mostly published outside traditional computer vision venues, our goal is to make QeCV accessible and actionable for a broader audience of computer vision researchers and engineers. By consolidating multiple contributions, we aim to bridge that gap and provide a comprehensive overview of existing QeCV methods, along with insights into future directions.\\n\\nWe present a practical “cookbook” for computer vision practitioners to begin exploring quantum-enhanced tech- niques today and to prepare for the growing impact of quan- tum technologies.

This is in particular consistent with what we learned that quantum states have norm 1, since the length of the compo- nents is related to measurement probabilities.\\n\\n(9)\\n\\n2.2 Gate-Based Quantum Computers\\n\\nAs alluded to in Sec. 2.1, the Schr¨odinger equation (10) gov- erns the evolution of a closed quantum system over time. Moreover, it can be proven that solving the Schr¨odinger equation always leads to a unitary time evolution [10, Chap- ter 2]. Gate-based quantum computers manipulate quantum states through a controlled sequence of unitary Hamil- tonian evolutions—each abstracted as a quantum gate—to perform computations. The specific algorithm implemented depends on the particular quantum gates chosen (Sec. 2.2.1). While the earlier quantum algorithms, including the famous algorithms of Shor [19] and Grover [69], are based on “handcrafted” quantum gates, increasingly quantum gates are selected by “training” on data to optimise an objective function [70], [71], [72] (Sec. 2.2.2).\\n\\n2.2.1 An Overview of Gate-based Quantum Algorithms\\n\\nSince algorithms under the gate-based model are often defined using a sequence of quantum gates, quantum algo- rithms are often framed as quantum circuits. Fig. 3 provides an overview of the major steps in a quantum algorithm, dis- played as an n-qubit quantum circuit. First, a basic quantum state (e.g. one of the classical states) is generated. Typically, the basic state is brought into superposition as a form of initialisation. Then, a sequence of quantum gates is applied to the initial state to achieve a final quantum state. Since a sequence of non-interrupted (e.g. without intermediate measurements) unitary transformations is equivalent to a single unitary transformation, the successive quantum gates that define the algorithm can be seen as a single quan- tum gate “block”. The final quantum state is not directly usable until it is measured, at which point it collapses to yield classical (binary) information. This collapse reduces the degrees of freedom available for further computation, which is why many quantum algorithms repeat the ini- tialise–transform–measure cycle multiple times—often with intermediate feedback—to amplify the probability of suc- cess and extract reliable outcomes from probabilistic quan- tum processes. Measurement mathematically manifests in projecting the quantum state onto the eigenbasis of a Hermi- tian operator known as an observable, with the output given by the eigenvalue of one of its eigenvectors (see Eq. (4) for an elementary example). The choice of observable depends on the algorithm, while the likelihood of obtaining a particular outcome is determined by the final quantum state.\\n\\nSimilar to classical algorithm design—where we are not concerned with the underlying implementation of the basic computational units (i.e. logical gates)—in quantum algorithm design, details of the physical realisation of the quantum gates and measurement devices are typically also abstracted away.\\n\\nConstraining the operations to be unitary transforma- tions can seem restrictive. However, it can be shown that all (classical) logical gates can be made reversible with- out significantly adding more bits or logical operations, thereby allowing the logical gates to be interpreted as unitary transformations [10, Sec. 1.4]. It turns out that any efficient classical algorithm can also be efficiently executed on a quantum computer in a analogous way [10, Sec. 3.2]. However, significant interest in gate-based quantum com- puters draws from their ability to solve certain problems\\n\\nFig. 3: Common processing stages in a typical quantum circuit. Here, the quantum circuit operates on n qubits, which at the beginning are often initialised to a basic state, e.g. |ψ1ψ2 ...ψn⟩ = |10...0⟩. Then, the basic state is pre- pared to yield an initial (usually superimposed) state, before a sequence of M quantum gates is invoked. The specific gates employed define the algorithm implemented. The final quantum state is then measured to produce classical outcomes that correspond to the final results, which are often probabilistic. It is also common for a circuit to be repetitively invoked or iterated.\\n\\nthat are beyond the reach of classical machines [19], [69] (Sec. A in the Appendix provides a rudimentary example of an algorithm with a theoretical speedup due to quantum effects). Before reviewing some applications of gate-based quantum computing to QeCV, it is essential to elaborate deeper on quantum gates and quantum circuits.\\n\\n2.2.2 Quantum Gates and Circuits\\n\\nAs alluded above, all classical logical gates (e.g. AND, OR, NAND) can be made reversible, i.e. the inputs can be recom- puted from the outputs. This can be achieved through the Toffoli gate, which has three input and three output bits4. By hardwiring selected inputs (to 0 or 1), the Toffoli gate can simulate all logical gates in a reversible manner. Details of reversible logical gates are beyond the scope of this survey; for that, we refer the reader to [10, Sec. 1.4].\\n\\nSingle-Qubit Gates.

A basic requirement for a reversible gate is that the number of input and output bits are the same.\\n\\n2.2 Gate-Based Quantum Computers\\n\\nAs alluded to in Sec. 2.1, the Schr¨odinger equation (10) gov- erns the evolution of a closed quantum system over time. Moreover, it can be proven that solving the Schr¨odinger equation always leads to a unitary time evolution [10, Chap- ter 2]. Gate-based quantum computers manipulate quantum states through a controlled sequence of unitary Hamil- tonian evolutions—each abstracted as a quantum gate—to perform computations. The specific algorithm implemented depends on the particular quantum gates chosen (Sec. 2.2.1). While the earlier quantum algorithms, including the famous algorithms of Shor [19] and Grover [69], are based on “handcrafted” quantum gates, increasingly quantum gates are selected by “training” on data to optimise an objective function [70], [71], [72] (Sec. 2.2.2).\\n\\n2.2.1 An Overview of Gate-based Quantum Algorithms\\n\\nSince algorithms under the gate-based model are often defined using a sequence of quantum gates, quantum algo- rithms are often framed as quantum circuits. Fig. 3 provides an overview of the major steps in a quantum algorithm, dis- played as an n-qubit quantum circuit. First, a basic quantum state (e.g. one of the classical states) is generated. Typically, the basic state is brought into superposition as a form of initialisation. Then, a sequence of quantum gates is applied to the initial state to achieve a final quantum state. Since a sequence of non-interrupted (e.g. without intermediate measurements) unitary transformations is equivalent to a single unitary transformation, the successive quantum gates that define the algorithm can be seen as a single quan- tum gate “block”. The final quantum state is not directly usable until it is measured, at which point it collapses to yield classical (binary) information. This collapse reduces the degrees of freedom available for further computation, which is why many quantum algorithms repeat the ini- tialise–transform–measure cycle multiple times—often with intermediate feedback—to amplify the probability of suc- cess and extract reliable outcomes from probabilistic quan- tum processes. Measurement mathematically manifests in projecting the quantum state onto the eigenbasis of a Hermi- tian operator known as an observable, with the output given by the eigenvalue of one of its eigenvectors (see Eq. (4) for an elementary example). The choice of observable depends on the algorithm, while the likelihood of obtaining a particular outcome is determined by the final quantum state.\\n\\nSimilar to classical algorithm design—where we are not concerned with the underlying implementation of the basic computational units (i.e. logical gates)—in quantum algorithm design, details of the physical realisation of the quantum gates and measurement devices are typically also abstracted away.\\n\\nConstraining the operations to be unitary transforma- tions can seem restrictive. However, it can be shown that all (classical) logical gates can be made reversible with- out significantly adding more bits or logical operations, thereby allowing the logical gates to be interpreted as unitary transformations [10, Sec. 1.4]. It turns out that any efficient classical algorithm can also be efficiently executed on a quantum computer in a analogous way [10, Sec. 3.2]. However, significant interest in gate-based quantum com- puters draws from their ability to solve certain problems\\n\\nFig. 3: Common processing stages in a typical quantum circuit. Here, the quantum circuit operates on n qubits, which at the beginning are often initialised to a basic state, e.g. |ψ1ψ2 ...ψn⟩ = |10...0⟩. Then, the basic state is pre- pared to yield an initial (usually superimposed) state, before a sequence of M quantum gates is invoked. The specific gates employed define the algorithm implemented. The final quantum state is then measured to produce classical outcomes that correspond to the final results, which are often probabilistic. It is also common for a circuit to be repetitively invoked or iterated.\\n\\nthat are beyond the reach of classical machines [19], [69] (Sec. A in the Appendix provides a rudimentary example of an algorithm with a theoretical speedup due to quantum effects). Before reviewing some applications of gate-based quantum computing to QeCV, it is essential to elaborate deeper on quantum gates and quantum circuits.\\n\\n2.2.2 Quantum Gates and Circuits\\n\\nAs alluded above, all classical logical gates (e.g. AND, OR, NAND) can be made reversible, i.e. the inputs can be recom- puted from the outputs. This can be achieved through the Toffoli gate, which has three input and three output bits4. By hardwiring selected inputs (to 0 or 1), the Toffoli gate can simulate all logical gates in a reversible manner. Details of reversible logical gates are beyond the scope of this survey; for that, we refer the reader to [10, Sec. 1.4].\\n\\nSingle-Qubit Gates. Single-qubit gates are elementary gates acting on one single input qubit |ψ⟩. For example, the Pauli gates\\n\\n(11)\\n\\nare used in many quantum algorithms.

In particular, setting α = 1 and β = 0 yields X |ψ⟩ = |1⟩, which can be interpreted as “flipping” the basic state of |0⟩ to |1⟩ (and vice versa by if α = 0 and β = 1). Indeed, the Pauli X gate is actually a (reversible) NOT gate.\\n\\nAnother basic quantum gate is the Hadamard gate\\n\\nwhich is commonly used to bring basic states into super- position (and vice versa). e.g. applying H on |1⟩ yields H |1⟩ = 1√ (|0⟩ − |1⟩), i.e. a state of uniform superposition. 2 Applying H again on the above result yields the initial basic state: H(H |1⟩) = HH |1⟩ = |1⟩. As can be deduced, apply- ing quantum gates successively is equivalent to performing a quantum operation that is defined by the multiplication of the corresponding unitary matrices.

It is easy to verify that sequentially applying H⊗2 twice is the same as performing the identity operation I4. Controlled Gates.

Through more elaborate applications of sequential multiplication and tensor operations, a set of universal quantum gates can simulate any unitary trans- formation in C2n up to arbitrary accuracy [10, Chapter 4.5]. Hence, in theory, a gate quantum computer needs only to physically implement a small set of unique quantum gates. Parameterised Gates.

Typically, the loss function for training a PQC has the following form:\\n\\nwhere x are training samples, ρx(θ) = |ψx(θ)⟩⟨ψx(θ)| is the density operator describing the quantum state before measurement, Mx is a certain problem-dependent observ- able, Tr is the trace operator and fx is the function that pushes the quantum circuit to learn the pattern of the data. Standard f(x) include mean-squared errors, mean- averaged errors for regressions and others for classifica- tions. In simple terms, Tr(ρx(θ)Mx) is the expectation value on the observable Mx on the quantum state |ψx(θ)⟩, so Tr(ρx(θ)Mx) = ⟨ψx(θ)|Mx|ψx(θ)⟩. PQCs are differentiable and their gradient can be evaluated using the so-called parameter-shift rule [73]. Small-scale PQCs can even be simulated classically, in which case auto-differentiation and back-propagation can be used for the training. PQCs belong to a larger class of quantum algorithm named Quantum Machine Learning (QML) [53], [54], [74], [75].\\n\\n2.3 Adiabatic QC and Quantum Annealing\\n\\nAdiabatic Quantum Computing (AQC) is another quantum computational paradigm different from gate-based quan- tum computing discussed in the previous section. Instead of representing unitary transformations using a sequence of well-defined (pre-defined or learned) elementary unitary transformation blocks, AQC performs useful calculations through a continuous transition between Hamiltonians. To put it simply, in classical computing terms, Hamiltonians can be thought of as energy functions; those are mathemati- cal expressions that describe how energy is distributed in a system. A transitioning, or a time-dependent Hamiltonian, then acts as an evolving energy landscape, with the goal being to guide the quantum system toward an optimal solu- tion. The choice of this Hamiltonian is crucial and structured in a way that naturally aligns with the optimization problem being solved. Next, we discuss the operational principle of AQC grounded on the adiabatic theorem of quantum mechanics [76].\\n\\nSuppose we are given a fixed initial Hamiltonian H(0) = HI and that it is physically possible to create an initial quantum state |ψ(0)⟩ that is an eigenvector to the smallest eigenvalue of the operator H(0).

To harness these effects for prac- tical computation, two primary paradigms, governed by two physical principles, have emerged: Adiabatic Quantum Computing (AQC) [11], [15] and gate-based quantum com- puting [10], [16]. AQC relies on the smooth evolution or annealing of a so-called Hamiltonian to guide the system toward its lowest-energy state, making it naturally suited for optimisation problems, particularly those expressed in the Quadratic Unconstrained Binary Optimisation (QUBO) form. In contrast, gate-based quantum computing employs discrete unitary transformations, offering greater flexibility in algorithm design. Together, these paradigms define mod- ern quantum computation, each with distinct advantages that depend on the specific problem domain.\\\\n\\\\nBroadly speaking, Quantum Computing (QC) allows designing algorithms to solve several classes of computa- tionally challenging problems with possible computational gains depending on the type of QC and the problem. The type of computational gains can range from improvements in asymptotic complexity (compared to the best classical counterparts) [17] to the acceleration of computations in absolute terms (in the same complexity class) [18]. Quantum computers operate on qubits, counterparts of classical bits that leverage quantum effects. These qubits abstractly span a Hilbert space, where computation takes place. In theory, a quantum computer can perform everything a classical com- puter can perform and vice versa. However, the correspond- ing Hilbert space of multiple qubits is exponentially large (2n-dimensional for n qubits), due to the tensor product structure of quantum mechanics, and so-called entangled states where the qubits cannot be described separately. Classical computation of the corresponding exponentially large operators would, of course, be highly time-consuming.\\\\n\\\\nAs of 2023-2025, we observe a transition in the field thanks to the proliferation of real quantum hardware: If previously (pre-2015), quantum hardware was accessible predominantly to researchers developing it, multiple quan- tum and quantum-inspired computers (e.g. adiabatic, gate- based machines, photonic machines, quantum simulators and quantum-inspired optimisers) can nowadays be ac- cessed by researchers from different fields, and the devel- oped methods can be tested on real quantum hardware. This is in contrast to the vast majority of papers on quantum algorithms published before, including highly influential ones that have been tested on very small problems on real quantum hardware so far [19], [20], [21]. For the next two decades, experts predict a super-linear increase in the number of qubits [22] and substantial improvements in the properties of the individual qubits (such as their decoher- ence and connectivity properties). We argue that these pre- dictions should be taken seriously, because the investments in quantum computing and algorithm development are sub- stantial; many national and international initiatives related to quantum computing were brought into being within the last several years. Quantum computing power on selected algorithms scales super-linearly (up to exponentially) with the number of qubits.

To harness these effects for prac- tical computation, two primary paradigms, governed by two physical principles, have emerged: Adiabatic Quantum Computing (AQC) [11], [15] and gate-based quantum com- puting [10], [16]. AQC relies on the smooth evolution or annealing of a so-called Hamiltonian to guide the system toward its lowest-energy state, making it naturally suited for optimisation problems, particularly those expressed in the Quadratic Unconstrained Binary Optimisation (QUBO) form. In contrast, gate-based quantum computing employs discrete unitary transformations, offering greater flexibility in algorithm design. Together, these paradigms define mod- ern quantum computation, each with distinct advantages that depend on the specific problem domain.\\\\n\\\\nBroadly speaking, Quantum Computing (QC) allows designing algorithms to solve several classes of computa- tionally challenging problems with possible computational gains depending on the type of QC and the problem. The type of computational gains can range from improvements in asymptotic complexity (compared to the best classical counterparts) [17] to the acceleration of computations in absolute terms (in the same complexity class) [18]. Quantum computers operate on qubits, counterparts of classical bits that leverage quantum effects. These qubits abstractly span a Hilbert space, where computation takes place. In theory, a quantum computer can perform everything a classical com- puter can perform and vice versa. However, the correspond- ing Hilbert space of multiple qubits is exponentially large (2n-dimensional for n qubits), due to the tensor product structure of quantum mechanics, and so-called entangled states where the qubits cannot be described separately.

Not many problems in computer vision can be formulated in a form consumable by modern quantum hardware. The estimated number of qubits necessary for practical computer vision problems with gate quantum computing formulations that\\\\n\\\\nmake use of provably advantageous quantum algorithms is typically larger than available on NISQ architectures. It is rare that QUBO forms are available and can be directly tested on an AQC. Often, it is the case that the target problem first has to be mapped to QUBO, and the solution has to be encoded in binary form. It is, therefore, of broad scientific interest that computer vision (and machine learn- ing) problems can be formulated for quantum computing and efficiently solved with it, while offering advantages compared to their classical method counterparts. Moreover, using a quantum mindset to CV problems can provide a new perspective, leading to new insights for classical CV and new methods, especially for the field in which many things are empirical. We discuss these aspects in Sec. 3. Related Research Fields. Several research fields related to QeCV can be identified in the literature, such as quantum-inspired computer vision, Quantum Image Pro- cessing (QIP), and Quantum Machine Learning (QML).\\\\n\\\\nThe first category simulates quantum-mechanical effects or draws inspiration from quantum mechanics [41], [42], [43], [44], [45]. These algorithms are not meant for execution on quantum hardware and are solely inspired by quantum phenomena. They should not be confused with techniques that can execute on quantum hardware. The second method category, i.e. QIP, is a field of quantum information pro- cessing focusing on representing and processing images as quantum states [46], [47], [48]. QIP provides several faster algorithms (in theory) for multiple widely-used linear alge- bra operations and common low-level operations on images [49], [50], [51].\\\\n\\\\nBoth method categories above can be broadly seen as sub-fields of QeCV, though distinct from this survey’s focus on mid- and high-level computer vision tasks (e.g. point set or mesh alignment, object tracking, and robust fitting). In contrast, just as classical ML is deeply intertwined with CV, quantum machine learning [52], [53], [54] explores the intersection of quantum computing and machine learning to enhance learning algorithms. It holds promise for QeCV, potentially accelerating tasks such as image classification, object detection, and pattern recognition. However, current QML methods remain largely theoretical, with limited prac- tical applications due to quantum hardware and scalability constraints. Hence, QML remains distant from this survey’s focus on practical applications to CV.\\\\n\\\\n1.2 Motivation and Scope of this Survey\\\\n\\\\nIn the broad sense, this survey shows by reviewing the first works in the field, how quantum computations and quantum hardware can be leveraged for computer vision. It showcases recent and ongoing progress towards practical quantum computing and computer vision, discusses the current state of the art, limitations therein, expected progress and its impact on computer vision. Our goal is to provide a shared, computer-science-friendly language and mathematical for- mulation of quantum computing, covering its two modern paradigms, i.e. gate-based quantum computing and adia- batic quantum computation. We identify and classify com- puter vision problems that can be addressed by quantum computers and analyse what they do have in common.\\\\n\\\\nWe observe that the quantum technology acts more and more like a booster for algorithm development in CV. The\\\\n\\\\nfact that the developed methods could run on real quantum hardware often brings us to interesting discoveries. Thus, we can often obtain methods that work better than existing classical ones.\\\\n\\\\nThere are several considerations regarding the gate- based model vs adiabatic model. Gate-based QCs are cur- rently severely limited in the number of qubits, their con- nectivity patterns and the accuracy of operations (gates) that can be applied to the qubits. Additionally, decoher- ence poses a significant obstacle. Thus, the largest num- ber factorised on gate-based quantum hardware using the celebrated Shor’s algorithm remains 21 for more than ten years as of the moment of writing [55], [56]. In contrast, the number of qubits in modern quantum annealers such as D- Wave is larger, which in combination with their connectivity and qubit characteristics allows for solving combinatorial optimisation problems in the Ising encodings of sizes rele- vant to computer vision and real-world applications. Also, qubit coherence times required for AQC are shorter than for gate-based machines, which partially explains the better scalability of quantum annealers compared to gate-based machines. Hence, the interest in especially applying AQC in computer vision has grown substantially over the last three years.\\\\n\\\\nThis survey focuses on computer vision methods for gate-based quantum computers and quantum annealers that have been evaluated on real quantum hardware (in the case of adiabatic quantum annealers) or simulators of gate-based quantum computers. We include a few theoretical works on gate-based quantum computing in computer vision without experiments on a simulator though this survey is gener- ally structured to reflect the applied focus of QeCV. Since computer vision is an applied science, we believe that the criterion of experimentation on quantum hardware is piv- otal, especially because modern quantum machines already allow solving problems of sizes encountered in practical applications. That is why we believe it is important that the methods are evaluated and the exposition is not restricted to theoretical considerations.\\\\n\\\\nPaper Selection Criteria. QeCV is a nascent field. In line with its aspirational definition, this survey presents an overview of methods designed for full or hybrid execution (i.e. classical-quantum) on quantum hardware, emphasising approaches that report theoretically grounded results with potential relevance to QeCV. Hence, the main paper selec- tion criterion for this survey is experimental evaluation of the proposed techniques and, at least, some results obtained on real quantum hardware. Moreover, we focus on works published at computer vision conferences (CVPR, ICCV and ECCV) and other venues (perhaps interdisciplinary) that are interested in the application of quantum computers in vision. We also include several technical reports on arXiv.org if they fulfil the main paper selection criterion. The authors made efforts to provide as complete review of the field as possible, but cannot claim completeness in every aspect, since the field is getting momentum and growing. We also recommend interested readers to read the discussed papers for more details.\\\\n\\\\nRelated Surveys.

Recently, Quantum Machine Learning (QML) has gained significant attention as it is now a fast- growing area. The large body of works in the QML space has\\\\n\\\\nbeen reviewed in [57], [58], whereas [57], [59], [60] also focus on quantum approaches for tackling optimisation problems. Out of all machine learning models, quantum deep learning requires special attention due to the impact of these learning machines in the field of AI. Massoli et al. [61] gather, compare and analyse the current state-of-the-art concerning Quantum Neural Networks (QNN). Yarkoni et al. [62], on the other hand, look into possible industry applications of Quantum Annealing (QA); their survey is perhaps closest to our work in terms of focusing on an application area of QA.\\\\n\\\\nMohseni et al. [18] review different methods for solv- ing Ising problems (exactly or approximately) and discuss quantum annealing as one meta-heuristic. A few surveys focus on quantum annealing for physicists [63], whereas our work is written for researchers with a computer vision back- ground. The short survey by Larasati et al. [64] provides a summary of a few quantum computer vision methods (<5% of what we cover) and is much less comprehensive than our article. Another brief paper by Mebtouche et al. [65] reviews the foundations of quantum computing, machine learning and multiple low-level vision and image processing tech- niques. In this regard, ours is the first comprehensive survey of its kind with an emphasis on QeCV.\\\\n\\\\nTarget Audience. This survey it is written for applied com- puter scientists, especially computer vision researchers and practitioners, who may have little to no background in theoretical physics. Unlike previous surveys [18], [57], [58], [59], [60], [61], [65] on quantum algorithms, mostly published outside traditional computer vision venues, our goal is to make QeCV accessible and actionable for a broader audience of computer vision researchers and engineers. By consolidating multiple contributions, we aim to bridge that gap and provide a comprehensive overview of existing QeCV methods, along with insights into future directions.\\\\n\\\\nWe present a practical “cookbook” for computer vision practitioners to begin exploring quantum-enhanced tech- niques today and to prepare for the growing impact of quan- tum technologies. While the survey avoids deep dives into physics and quantum theory, it includes sufficient technical detail to ensure a solid foundation for the presented results and the validity thereof. Physical assumptions are clearly separated from the mathematical consequences relevant to algorithmic design. The intended readership includes:\\\\n\\\\n• Computer vision researchers seeking to understand whether their work can benefit from quantum comput- ing;\\\\n\\\\n• Computer vision practitioners interested in experiment- ing with QeCV algorithms or integrating quantum solvers into their workflows;\\\\n\\\\n• Computer science students at various levels who are curious about the intersection of computer vision and applied quantum computing.\\\\n\\\\nWe hope this survey will serve as a gateway for new researchers to enter the field and contribute to its devel- opment.\\\\n\\\\n1.3 Structure of this Survey\\\\n\\\\nThis survey is structured in six sections. Sec. 2 reviews foundations of quantum computing relevant to quantum- enhanced computer vision methods including two main\\\\n\\\\nquantum computational paradigms, i.e. gate-based (or circuit-based) and adiabatic quantum computing, as well as the design and hardware of quantum computers. Moreover, as part of it, Sec. 3.1.2 discusses the encoding of classical data as quantum states suitable for processing on quantum hardware, which is one of the essential steps in quantum- enhanced computer vision. Next, Sec. 3 is devoted to algo- rithms and applications. It reviews methods for different problems such as point set alignment, mesh registration, object tracking, model fitting, quantum machine learning for vision, implicit representations and generative approaches, among others. We then discuss open challenges, specifics of the field and social implications in Sec. 5, and conclude in Sec. 6.\\\\n\\\\n2 OPERATIONAL PRINCIPLES OF QCS\\\\n\\\\nThis section reviews the foundations of quantum computing necessary as a short introduction (or a refresher) to the field and sufficient for understanding the published literature reviewed in Sec. 3. Sec. 2.1 introduces fundamentals such as notations and elementary operations on qubits. Secs. 2.2 and 2.3 describe the two main quantum computational paradigms—namely, gate-based quantum computing and quantum annealing, respectively—and Sec. 2.4 establishes their connections and equivalency.

Out of all machine learning models, quantum deep learning requires special attention due to the impact of these learning machines in the field of AI. Massoli et al. [61] gather, compare and analyse the current state-of-the-art concerning Quantum Neural Networks (QNN). Yarkoni et al. [62], on the other hand, look into possible industry applications of Quantum Annealing (QA); their survey is perhaps closest to our work in terms of focusing on an application area of QA.\\\\n\\\\nMohseni et al. [18] review different methods for solv- ing Ising problems (exactly or approximately) and discuss quantum annealing as one meta-heuristic. A few surveys focus on quantum annealing for physicists [63], whereas our work is written for researchers with a computer vision back- ground. The short survey by Larasati et al. [64] provides a summary of a few quantum computer vision methods (<5% of what we cover) and is much less comprehensive than our article. Another brief paper by Mebtouche et al. [65] reviews the foundations of quantum computing, machine learning and multiple low-level vision and image processing tech- niques. In this regard, ours is the first comprehensive survey of its kind with an emphasis on QeCV.\\\\n\\\\nTarget Audience. This survey it is written for applied com- puter scientists, especially computer vision researchers and practitioners, who may have little to no background in theoretical physics. Unlike previous surveys [18], [57], [58], [59], [60], [61], [65] on quantum algorithms, mostly published outside traditional computer vision venues, our goal is to make QeCV accessible and actionable for a broader audience of computer vision researchers and engineers. By consolidating multiple contributions, we aim to bridge that gap and provide a comprehensive overview of existing QeCV methods, along with insights into future directions.\\\\n\\\\nWe present a practical “cookbook” for computer vision practitioners to begin exploring quantum-enhanced tech- niques today and to prepare for the growing impact of quan- tum technologies. While the survey avoids deep dives into physics and quantum theory, it includes sufficient technical detail to ensure a solid foundation for the presented results and the validity thereof. Physical assumptions are clearly separated from the mathematical consequences relevant to algorithmic design. The intended readership includes:\\\\n\\\\n• Computer vision researchers seeking to understand whether their work can benefit from quantum comput- ing;\\\\n\\\\n• Computer vision practitioners interested in experiment- ing with QeCV algorithms or integrating quantum solvers into their workflows;\\\\n\\\\n• Computer science students at various levels who are curious about the intersection of computer vision and applied quantum computing.\\\\n\\\\nWe hope this survey will serve as a gateway for new researchers to enter the field and contribute to its devel- opment.\\\\n\\\\n1.3 Structure of this Survey\\\\n\\\\nThis survey is structured in six sections. Sec. 2 reviews foundations of quantum computing relevant to quantum- enhanced computer vision methods including two main\\\\n\\\\nquantum computational paradigms, i.e. gate-based (or circuit-based) and adiabatic quantum computing, as well as the design and hardware of quantum computers. Moreover, as part of it, Sec. 3.1.2 discusses the encoding of classical data as quantum states suitable for processing on quantum hardware, which is one of the essential steps in quantum- enhanced computer vision. Next, Sec. 3 is devoted to algo- rithms and applications. It reviews methods for different problems such as point set alignment, mesh registration, object tracking, model fitting, quantum machine learning for vision, implicit representations and generative approaches, among others. We then discuss open challenges, specifics of the field and social implications in Sec. 5, and conclude in Sec. 6.\\\\n\\\\n2 OPERATIONAL PRINCIPLES OF QCS\\\\n\\\\nThis section reviews the foundations of quantum computing necessary as a short introduction (or a refresher) to the field and sufficient for understanding the published literature reviewed in Sec. 3. Sec. 2.1 introduces fundamentals such as notations and elementary operations on qubits. Secs. 2.2 and 2.3 describe the two main quantum computational paradigms—namely, gate-based quantum computing and quantum annealing, respectively—and Sec. 2.4 establishes their connections and equivalency. Sec. 2.5 examines po- tential advantages of quantum computing over classical computing and Sec. 2.6 discusses hardware designs and realizations of quantum computers.\\\\n\\\\nNote that we do not review complexity classes associated with the quantum computational paradigm, as their discus- sion is outside the scope.

While minor for- ward–reverse discrepancies are expected due to training lim- itations and imperfect regression of the velocity field, we observe that these inconsistencies vary systematically with resolution. In particular, the misalignment becomes substan- tially worse when sampling at resolutions that deviate from the model’s training resolution.\\n\\nTo understand this phenomenon, we compare the outputs of the forward noise process across different resolutions using the same noise level σt. As shown in Figure 1(a), more signal is destroyed in the low-resolution images in this forward process compared to the high-resolution ones, despite the shared diffusion schedule {σt}. This suggests that the perceptual impact of noise is resolution-dependent.\\n\\nWe hypothesize that this effect arises from spatial com- pression. In low-resolution images, each pixel encodes a larger region of semantic content, so adding noise dispro- portionately disrupts meaningful structure. In contrast, high- resolution images have greater spatial redundancy, which makes the same level of noise less perceptually destructive.

Besides cropping artifacts likely caused by positional encodings, generated images often exhibit structural glitches and texture breakdowns (top). Our method (bottom) improves visual fidelity by calibrating the conditioning noise level without retraining or architectural changes.\\n\\n(b) MSE between forward and reverse trajectories across timesteps t at different resolutions. Misalign- ment increases with resolution shift, especially at early steps.\\n\\nFigure 2. Training-testing misalignment in diffusion sampling. The forward (noise addition) and reverse (denoising) processes are theoretically symmetric but diverge during test-time sampling. (a) illustrates the conceptual discrepancy. (b) plots the mean squared error between the predicted and actual noisy image across sampling steps.\\n\\nResolution-Dependent Misalignment. While minor for- ward–reverse discrepancies are expected due to training lim- itations and imperfect regression of the velocity field, we observe that these inconsistencies vary systematically with resolution. In particular, the misalignment becomes substan- tially worse when sampling at resolutions that deviate from the model’s training resolution.\\n\\nTo understand this phenomenon, we compare the outputs of the forward noise process across different resolutions using the same noise level σt. As shown in Figure 1(a), more signal is destroyed in the low-resolution images in this forward process compared to the high-resolution ones, despite the shared diffusion schedule {σt}. This suggests that the perceptual impact of noise is resolution-dependent.\\n\\nWe hypothesize that this effect arises from spatial com- pression. In low-resolution images, each pixel encodes a larger region of semantic content, so adding noise dispro- portionately disrupts meaningful structure. In contrast, high- resolution images have greater spatial redundancy, which makes the same level of noise less perceptually destructive. As a result, a fixed σt induces qualitatively different levels of corruption depending on resolution.\\n\\nTo quantify this, we analyze SSIM between clean images x0 and their forward-noised counterparts xt across multi- ple resolutions.

Resolution-Aware Test-Time Calibration\\n\\nWhile recent methods have extended diffusion models to ar- bitrary resolutions by adapting token lengths or position en- codings [28], we focus instead on correcting forward-reverse misalignment through test-time adjustment of the condition- ing noise level. Rather than modifying the sampling tra- jectory or retraining the model, we propose a lightweight post-processing procedure that adjusts only the input noise level ˆσt passed to the denoiser at each timestep.\\n\\nRole of Noise-Level Embedding. At each timestep, diffu- sion models receive not only the noisy latent xt but also a noise-level or timestep embedding that encodes the expected magnitude of corruption in the input. This embedding allows the model to adapt its prediction of the denoised image based on how noisy the input is: for low noise, the model performs minor corrections, whereas for high noise, it applies stronger denoising. In our framework, the conditioning noise ˆσt is directly mapped to this embedding. Consequently, by ma- nipulating ˆσt at test time, we can explicitly interfere how the model interprets the noise level in the input, enabling a resolution-aware correction without changing the learned weights or the sampling schedule.\\n\\nProblem Setup. Let ϕ denote a trained flow-matching diffusion model with a predefined noise schedule σtt = 0T. At each timestep t, the model receives a noisy latent xt+1 and a noise-level embedding derived from a conditioning noise ˆσt. This embedding informs the network how much noise to expect and guides its prediction of the velocity field ϕ(xt+1, ˆσt).\\n\\nIn standard sampling, ˆσt = σt follows the original noise schedule. In our approach, we allow ˆσt to differ from σt to correct forward–reverse misalignment at test time. By tuning ˆσt, we can adapt the model’s denoising behavior to different resolutions without changing the learned weights or sampling procedure.\\n\\nGiven a noisy latent input xt+1, we expect xt to match the forward sample obtained by applying Gaussian noise to a clean latent x0. Our goal is to find a conditioning noise level ˆσt such that the denoised prediction ˆxt minimizes the discrepancy from xt:\\n\\nCoarse-to-Fine Search Strategy. We estimate ˆσ∗ t via a coarse-to-fine grid search that minimizes the one-step reverse error at each timestep. Starting from the final step t = T−1, we proceed backward in time.

These results suggest that NoiseShift comple- ments, but does not replace, the resolution-aware scheduling baked into the model itself.\\n\\n5.4. Ablation Studies\\n\\nThis section studies the number of samples used in the Noise- Shift calibration. As shown in Figure 5, even though the number of samples varies from 50 to 200, the calibrated sigmas always converge in almost the same range. Given the fact that the calibration already has a very low computation cost, reducing the number of samples can lead to an almost free re-calibration, which improves the low-resolution image generation quality.\\n\\n5.5. Qualitative Results\\n\\nIn Figure 7 and Figure 6, we present qualitative examples of SD3 and SD3.5 [9] before and after applying NoiseShift on CelebA and LAION-COCO. Across all resolutions, Noise- Shift improves the overall image quality, providing better structure and textures of the generated images. In Figure 3, we show how NoiseShift improves the Flux-Dev model down to 64×64 resolutions. Overall, we observe the quality im- provement and fewer artifacts across the resolutions.\\n\\n6. Conclusion\\n\\nWe identify resolution-dependent exposure bias as a key contributor to quality degradation in state-of-the-art diffusion models when sampling at lower resolutions. To address this, we introduced NoiseShift, a simple, training-free approach that recalibrates the denoising conditioning to better align with resolution-specific noise distributions. Our method consistently improves image quality across resolutions and is complementary to both noise schedule modifications and architectural enhancements, making it readily applicable to recent advances in text-to-image generation.\\n\\nLimitations and Future Work. While NoiseShift miti- gates exposure bias and enhances cross-resolution perfor- mance, it does not fully solve the challenge of low-resolution generalization. Future work may explore integrating Noise- Shift with learned adapters, dynamic token routing, or resolution-specific fine-tuning strategies.\\n\\nBroader Impact. By enhancing sample quality at low res- olutions, NoiseShift increases the adaptability of text-to- image systems to diverse deployment settings, including mobile and assistive applications. However, the ability to generate increasingly high-quality synthetic content may also exacerbate issues around misinformation and image provenance, highlighting the need for responsible use and effective detection mechanisms.\\n\\nFigure 6.

The models feature some novel techniques like MXFP4 quantization, efficient kernels, a brand new chat format, and more. To enable the release of gpt-oss through transformers, we have upgraded the library considerably. The updates make it very efficient to load, run, and fine-tune the models.\\n\\nIn this blog post, we talk about all the upgrades in-depth, and how they become part of the transformers toolkit so other models (current and future) can benefit from them. Providing clean implementations of new methods in transformers also allows the community to quickly understand and adopt them. Frameworks such as MLX, llama.cpp or vLLM can use the transformers code as a reference to build their own implementations.\\n\\nFor this release, we worked on:\\n\\nZero-build Kernels, downloadable from the Hub\\n\\nMXFP4 Quantization\\n\\nTensor Parallelism\\n\\nExpert Parallelism\\n\\nDynamic Sliding Window Layer & Cache\\n\\nContinuous Batching & Paged Attention\\n\\nLoad larger models faster\\n\\nBest part: Most of these features should work across all major models within transformers!\\n\\nZero-build Kernels, downloadable from the Hub\\n\\nA kernel is a specialized, compact program that runs on accelerators to execute tasks like matrix multiplications, activations, or normalizations. In eager PyTorch, operations trigger individual kernels sequentially, which is straightforward but can incur extra memory transfers and launch overheads. PyTorch 2.0\\'s torch.compile with backends like TorchInductor addresses this by automatically fusing and optimizing kernels, delivering 2–10× performance gains.\\n\\nIn addition, the community has created custom kernels for frequent combinations of operations, not just individual PyTorch ops like matmul. For example, Flash Attention was created to optimize the critical attention block that defines the transformers architecture, and is present in many models including most LLMs. By carefully combining all the attention operations inside a single kernel, memory transfers are minimized, memory use is reduced, and speedups can be achieved.\\n\\nThe problem is that all these various kernels are available in separate libraries, which creates a dependency bloat if they were to be added to the transformers library. Furthermore, these kernels are not just Python code, they consist of low-level cuda code, glued together with C++ and exposed through a Python layer. This means they have to be compiled in the target system, which in turn requires whatever build system is required by each kernel library.\\n\\nThe kernels package solves this problem by downloading pre-built binaries of supported kernels from the Hub. You just indicate the kernel you want to use, and kernels will look for a version compatible with your system and download it on first use.\\n\\nCustom Kernels for GPT-OSS\\n\\nGPT-OSS, a Mixture of Experts (MoE) model, is a big user of Kernels from the Hub. It leverages several custom kernels:\\n\\nLiger RMSNorm, used as @use_kernel_forward_from_hub(\"RMSNorm\")`\\n\\nMegablocks MoE kernels: @use_kernel_forward_from_hub(\"MegaBlocksMoeMLP\")\\n\\nFlash Attention 3 with support for attention sinks.\\n\\nMXFP4 triton kernels (covered later)\\n\\nLet\\'s take a look at the first two ones.\\n\\nBehind the scenes, the decorators (1 and 2) simply point to community-contributed kernels. For example, RMSNorm comes from liger_kernels, while the MegaBlocksMoeMLP kernel comes from megablocks. Depending on your device (CUDA or ROCm) and whether you’re training or running inference, the right kernel is pulled in automatically.\\n\\nThis design is both specific and general: the RMSNorm liger kernels are already being reused across multiple models, and the MoE kernel could be applied to future MoEs as well.\\n\\nBecause kernels pulls code from the Hub, you have to opt-in to this feature by passing use_kernels=True in your model instantiation, as shown below. We enable INFO logging in the example so you can easily verify that downloadable kernels are in use.\\n\\nThese kernels are not compatible with mxfp4, so inference will happen in bfloat16 if you use them. Please, benchmark your system for the best combination in memory and throughput that suits your project!\\n\\nfrom transformers import AutoTokenizer, AutoModelForCausalLM import logging logging.basicConfig(level=logging.INFO) model_id = \"openai/gpt-oss-20b\" tokenizer = AutoTokenizer.from_pretrained(model_id) model = AutoModelForCausalLM.from_pretrained( model_id, dtype=\"auto\", device_map=\"auto\", use_kernels=True, )\\n\\nRunning a quick generation yields log messages like\\n\\nINFO:root:Using layer `LigerRMSNorm` from repo `kernels-community/liger_kernels` INFO:root:Using layer `MegaBlocksMoeMLP` from repo `kernels-community/megablocks`\\n\\nFigure 1 shows that, in the system we tested, these kernels work best for larger batch sizes. We always recommend to benchmark any performance-related changes as closely to your production conditions as possible.\\n\\nFigure 1: Benchmarking results of custom kernels\\n\\nYou can explore and play with the benchmarking script here\\n\\nFlash Attention 3\\n\\nOpenAI gpt-oss models use attention sinks, which improves quality and facilitates the use of longer contexts. The vLLM team added this feature to the latest version of Flash Attention (Flash Attention 3), and the resulting custom kernel is available on the Hub. Currently, this kernel is compatible with the Hopper architecture. If you have one, this is the way to enable it:\\n\\nmodel = AutoModelForCausalLM.from_pretrained( model_id, dtype=\"auto\", device_map=\"auto\", + # Flash Attention with Sinks + attn_implementation=\"kernels-community/vllm-flash-attn3\", )\\n\\nMXFP4 Quantization\\n\\nLarge language models are memory-hungry. Quantization reduces memory footprint by storing weights (and sometimes activations) in lower-precision formats. For reference, FP32 uses 32 bits per number and BF16 uses 16. By reducing bit width, we trade some precision for smaller models and faster memory movement.\\n\\nIf you want a visual primer on quantization trade-offs, Maarten Grootendorst’s article is excellent: A Visual Guide to Quantization.\\n\\nWhat is MXFP4\\n\\nFigure 2: The E2M1 format used in the MXFP4 format\\n\\nMXFP4 is a 4-bit floating format with E2M1 layout: 1 sign bit, 2 exponent bits, and 1 mantissa bit, as shown in Figure 2. On its own, E2M1 is very coarse. MXFP4 compensates with blockwise scaling:\\n\\nVectors are grouped into blocks of 32 elements.\\n\\nEach block stores a shared scale that restores dynamic range when dequantizing.\\n\\nInside each block, 4-bit values represent numbers relative to that scale.\\n\\nThis blockwise scheme lets MXFP4 keep range while using very few bits. In practice, GPT-OSS 20B fits in roughly 16 GB of VRAM and GPT-OSS 120B fits in roughly 80 GB when MXFP4 is active, which is the difference between “cannot load” and “can run on a single GPU.” The catch is that matrix multiplies now have to respect block scales. Doing this efficiently at scale requires dedicated kernels.\\n\\nMXFP4 in transformers\\n\\ntransformers now includes native support for MXFP4, leveraging optimized triton (MXFP4) kernels for enhanced performance. This builds on the community-driven kernel distribution discussed earlier, utilizing pre-compiled kernels from the Hub to simplify deployment.\\n\\nKey implementation details:\\n\\nQuantizer logic: Found in the MXFP4 quantizer file, this handles the core quantization process for MXFP4.\\n\\nIntegration hooks: The MXFP4 integration file enables seamless use of MXFP4 within the transformers framework.\\n\\nTo check if a model supports MXFP4, inspect its configuration:\\n\\nfrom transformers import GptOssConfig model_id = \"openai/gpt-oss-120b\" cfg = GptOssConfig.from_pretrained(model_id) print(cfg.quantization_config) # Example output: # { # \\'modules_to_not_convert\\': [ # \\'model.layers.*.self_attn\\', # \\'model.layers.*.mlp.router\\', # \\'model.embed_tokens\\', # \\'lm_head\\' # ], # \\'quant_method\\': \\'mxfp4\\' # }\\n\\nIf \\'quant_method\\': \\'mxfp4\\' is present, the model will automatically use the MXFP4 pathway with Triton kernels when supported.\\n\\nThanks to this pull request, you can fine-tune gpt-oss models and save them directly to the Hub in MXFP4 format, streamlining deployment with optimized performance.\\n\\nRequirements and fallbacks\\n\\nTo run MXFP4 on GPU you need:\\n\\naccelerate, kernels, and triton>=3.4 installed. Note that Pytorch 2.8 already comes with triton 3.4, so you only need to manually install triton if using Pytorch 2.7.\\n\\nNVIDIA GPU with compute capability ≥ 7.5. This goes all the way back to Tesla, so you can run gpt-oss-20b on the free tiers of Google Colab and Kaggle, and on many consumer GPUs.\\n\\nIf these constraints are not met, transformers falls back to a higher-precision path (bfloat16 is used by default), which requires about 4× the memory of MXFP4.\\n\\nThe snippet loads GPT-OSS twice on CUDA: once with Mxfp4Config(dequantize=True) (memory intensive) and once in the default quantized path (memory efficient). Figure 3 shows the amount of used VRAM after each load so you can visualize the savings.\\n\\nFigure 3: Memory requirements for the quantized and dequantized models\\n\\nKernels for MXFP4\\n\\nEfficient MXFP4 requires kernels that understand 32-element blocks and their scales during GEMMs and fused ops. This is where Kernels from the Hub comes in again. transformers automatically pulls in the MXFP4-aware Triton kernels from the community repository when you load a model that needs them. The repository will appear in your local cache and will be used during the forward pass. For the MXFP4 kernels one does not need to use the use_kernels=True parameter like before, it is set to default in transformers.\\n\\nQuick sanity check with the Hugging Face cache CLI, after running gpt-oss-20b on a GPU compatible with the triton MXFP4 kernels:\\n\\nhf cache scan\\n\\nSample output:\\n\\nREPO ID REPO TYPE SIZE ON DISK -------------------------------- --------- ------------ kernels-community/triton_kernels model 536.2K openai/gpt-oss-20b model 13.8G\\n\\nThis indicates the MXFP4 kernels were fetched and are available for execution.\\n\\nLet\\'s run some benchmarks and see how well the MXFP4 kernels perform. In Figure 4, we see that the MXFP4 kernels are even better than the custom MoE and RMSNorm kernels for larger batches.\\n\\nFigure 4: MXFP4 kernel benchmark\\n\\nYou can explore and play with the benchmarking script here\\n\\nTensor Parallelism\\n\\nFigure 5: Explanation of tensor parallelism.\\n\\nTensor Parallelism (TP) splits tensors inside a layer across multiple GPUs (as shown in Figure 5). Each GPU multiplies its shard in parallel, and then partial results are collected using all-gather or all-reduce operations. This reduces per-GPU memory and keeps all GPUs working on the same layer, which improves throughput as sequence length or batch size grow. TP is communication-intensive and generally works best on a single machine with fast intra-node links.\\n\\nWhat this enables in transformers\\n\\ntransformers implements TP directly in from_pretrained. You can start with the predefined plan:\\n\\n# run with: torchrun --nproc-per-node 4 tp_gpt_oss.py import torch from transformers import PreTrainedTokenizerFast, GptOssForCausalLM model_id = \"openai/gpt-oss-120b\" tokenizer = PreTrainedTokenizerFast.from_pretrained(model_id) model = GptOssForCausalLM.from_pretrained( model_id, tp_plan=\"auto\", # built in TP support dtype=\"auto\", ).eval() messages = [ {\"role\": \"system\", \"content\": \"Be concise.\"}, {\"role\": \"user\", \"content\": \"Explain KV caching briefly.\"}, ] inputs = tokenizer.apply_chat_template( messages, add_generation_prompt=True, return_tensors=\"pt\", return_dict=True, reasoning_effort=\"low\", ).to(model.device) with torch.inference_mode(): generations = model.generate(**inputs, max_new_tokens=128) print(tokenizer.decode(generations[0][inputs[\"input_ids\"].shape[-1]:]))\\n\\nIf you don’t have the infrastructure to run the above, you can just spawn a process on our GPUs using Hugging Face Jobs!\\n\\nhf jobs run --detach --flavor l4x4 ghcr.io/astral-sh/uv:debian /bin/bash -c \\\\ \"uv venv .venv --python 3.12 && \\\\ source .venv/bin/activate && \\\\ uv pip install --upgrade torch numpy transformers accelerate triton kernels && \\\\ wget https://huggingface.co/datasets/ariG23498/distributed/raw/main/tp_gpt_oss.py && \\\\ torchrun --nproc-per-node=4 tp_gpt_oss.py\"\\n\\nhf jobs is available for all Hugging Face PRO & Enterprise users.\\n\\nUnder the hood, tp_plan=\"auto\" selects a predefined sharding recipe for each layer and wires the necessary collectives. You can inspect the active plan with print(model._tp_plan) if you want to verify what is being sharded.\\n\\nWhen to reach for TP\\n\\nUse TP when the model is too large for one GPU and you want parallel compute, not only memory placement. TP tends to scale throughput with more GPUs, especially for long sequences or larger batches.\\n\\nIf you are curious about how TP differs from device_map=\"auto\" (memory placement), this short Stack Overflow answer explains the distinction and when to use each.\\n\\nTo learn more about TP, here are two must-read resources:\\n\\ntransformers guide: Tensor parallelism, supported models, plans, and extension points.\\n\\nUltra-Scale Playbook: background on TP and its relationship to other parallelism modes.\\n\\nExpert Parallelism\\n\\nExpert Parallelism (EP) shards experts inside MoE layers across GPUs. Each token is routed to one or a few experts, so only those experts run their feed-forward pass. Since experts are independent MLPs, we can place different experts on different ranks and exchange only the hidden states for the routed tokens. This keeps the matrix multiplies intact on each rank and replaces tensor slicing with routing and collectives.\\n\\nRun with multiple processes using torchrun. EP is enabled via the distributed configuration and works with GPT-OSS MoE layers out of the box in transformers.\\n\\n# run with: torchrun --nproc-per-node 4 ep_gpt_oss.py import torch from transformers import PreTrainedTokenizerFast, GptOssForCausalLM from transformers.distributed import DistributedConfig model_id = \"openai/gpt-oss-120b\" tokenizer = PreTrainedTokenizerFast.from_pretrained(model_id) model = GptOssForCausalLM.from_pretrained( model_id, distributed_config=DistributedConfig(enable_expert_parallel=True), # enabling EP dtype=\"auto\", ).eval() messages = [ {\"role\": \"system\", \"content\": \"Be concise.\"}, {\"role\": \"user\", \"content\": \"Explain KV caching briefly.\"}, ] inputs = tokenizer.apply_chat_template( messages, add_generation_prompt=True, return_tensors=\"pt\", return_dict=True, reasoning_effort=\"low\", ).to(model.device) with torch.inference_mode(): generations = model.generate(**inputs, max_new_tokens=128) print(tokenizer.decode(generations[0][inputs[\"input_ids\"].shape[-1]:]))\\n\\nHere is how you would run using hf jobs\\n\\nhf jobs run --detach --flavor l4x4 ghcr.io/astral-sh/uv:debian /bin/bash -c \\\\ \"uv venv .venv --python 3.12 && \\\\ source .venv/bin/activate && \\\\ uv pip install --upgrade torch numpy transformers accelerate triton kernels && \\\\ wget https://huggingface.co/datasets/ariG23498/distributed/raw/main/ep_gpt_oss.py && \\\\ torchrun --nproc-per-node=4 ep_gpt_oss.py\"\\n\\nWhen you enable Expert Parallelism, Tensor Parallelism is also activated. This means you enjoy the best of both worlds!\\n\\nDynamic Sliding Window Layer & Cache\\n\\nMany recent LLMs use sliding window attention, or a combination of sliding and global attention layers, as a means to save memory and reduce those expensive quadratic matmuls that grow with sequence length. However, the dynamic KV cache implementation in transformers used to continue to allocate space according to sequence length, without looking at the individual attention layers. You could always optimize memory using compilation (meaning, fixed shapes), but that\\'s a separate scenario altogether.\\n\\ntransformers now has a DynamicSlidingWindowLayer and a config‑aware DynamicCache. If the model config declares sliding‑window or hybrid attention (both sliding and global attention layers are used), the cache stops growing past the window for the sliding layers. If you don’t pass the config, behavior stays as before (full, ever‑growing KV as sequence length grows).\\n\\nFor models that only use sliding window layers, such as Mistral 7B, cache memory stops growing when the sequence reaches the window size (4096, in this case). This makes sense, because the sliding layers can\\'t look past the previous 4K tokens anyway.\\n\\nOpenAI gpt-oss alternates between sliding and global attention layers, which results in total KV cache memory being halved, as we\\'ll see, as sequence length increases. This provides us with:\\n\\nMuch lower KV‑cache memory for models with sliding or hybrid attention (e.g. GPT‑OSS). Cache growth plateaus once the window is reached (e.g., 4K for Mistral; 128 for GPT‑OSS sliding layers), instead of scaling linearly with total generated tokens. (GitHub, Transformers)\\n\\nSpeed/latency wins on long prompts/long generations: smaller KV tensors mean lighter attention reads/writes and less memory bandwidth pressure, especially after the window is hit. (This is the central motivation behind sliding‑window/hybrid LLMs.) (AI21, vLLM Blog)\\n\\nHow to use it\\n\\nThe optimized cache is set by default, that means you don\\'t have to make any changes to your existing code. If you want to create the DynamicCache explicitly here is how you would do it:\\n\\nfrom transformers import AutoModelForCausalLM, AutoTokenizer, DynamicCache model_id = \"openai/gpt-oss-20b\" tokenizer = AutoTokenizer.from_pretrained(model_id) model = AutoModelForCausalLM.from_pretrained( model_id, dtype=\"auto\", device_map=\"auto\", ).eval() messages = [ {\"role\": \"system\", \"content\": \"Always respond in riddles\"}, {\"role\": \"user\", \"content\": \"What is the weather like in Madrid?\"}, ] inputs = tokenizer.apply_chat_template( messages, add_generation_prompt=True, return_tensors=\"pt\", return_dict=True, reasoning_effort=\"low\", ).to(model.device) cache = DynamicCache(config=model.config) # create the cache with the model\\'s config generated = model.generate( **inputs, max_new_tokens=500, past_key_values=cache ) print(tokenizer.decode(generated[0][inputs[\"input_ids\"].shape[-1]:]))\\n\\nFigure 6 showcases how much of a difference it makes for us to use the Dynamic KV Cache with sliding window attention.\\n\\nFigure 6: The memory analysis of dynamic cache with sliding window attention\\n\\nContinuous Batching & Paged Attention\\n\\nA typical autoregressive generation process looks like Figure 7. You input the prefill tokens, and the model predicts each new token one after the other until it predicts the EOS (End of Sequence) token.\\n\\nFigure 7: Autoregressive token generation\\n\\nLet’s see what the generation process looks like when we pass a batch of inputs. In Figure 8 you notice that some generations finish off earlier than the others. This mismatch of length underutilizes the GPUs.\\n\\nFigure 8: Static batching of sequences\\n\\nThis type of batching sequences is called static batching. While this is simple and easy to understand, it inherently comes with inefficiencies. Only after each sentence is completely generated can we move on to the next batch.\\n\\nTo bypass this issue, we use dynamic batching (also known as continuous batching). Instead of waiting for all the generation to finish, we schedule incoming requests to the completed generations. That way, as soon as a generation in a batch is complete, we prefill the batch with the next request. The process looks like Figure 9.\\n\\nFigure 9: Continuous Batching of sequences\\n\\nTransformers supports continuous batching with the generate_batch API. This is not meant for production-grade model serving –frameworks like vLLM and SGLang are great at that–, but can be very helpful for evaluation and experimentation. Here is an example script that runs CB end to end on Qwen/Qwen3-4B-Instruct-2507.\\n\\nWe have also performed a benchmark between Continuous Batching and Static Batching with 100 samples. In Figure 9, we note that CB is quite faster than SB.\\n\\nFigure 9: Continuous vs Static Batching Tokens/Second\\n\\nYou can play around with the benchmark here: SB, CB\\n\\nLoad larger models faster\\n\\nWhen you load a large model into your GPU, PyTorch needs to reserve GPU memory for each layer’s weights. Each of these requests (per layer) takes time, and for multi-billion-parameter models it can mean thousands of tiny memory allocations, adding up to a long wait before the model is ready. Instead of asking the GPU for new memory every single time, it can hold on to a big chunk once and then hand out slices from it quickly.\\n\\nPyTorch allocators can do exactly this. The catch is that the allocator only gets fast after you’ve given it some memory to work with. If you don’t “stock the pantry” first, you still end up doing many slow trips to the market. This PR (🎉 #36380) taught transformers to pre-stock the pantry before it starts copying model weights.\\n\\nIt:\\n\\nLooks at the device_map (where each layer will live).\\n\\nPre-allocates a big enough block on each GPU.\\n\\nThen, as layers are copied in, they just slot neatly into this pre-reserved space.\\n\\nYou have to make no changes to your existing code, as this is default behaviour in transformers. If you use device_map=\"auto\" or provide your own device map, your model will now load faster automatically. If you’re running with Tensor Parallel (tp_plan=\"auto\") and torchrun you also benefit from companion changes that make multi-GPU loading smarter.\\n\\nConclusion\\n\\ntransformers moves quickly and it is community-first. The library evolves at the pace of the field because contributors shape it in the open. Pieces added for new models become part of the toolkit and are reused in future integrations.\\n\\nThis velocity enables day-zero integrations like the GPT-OSS series. As the stack becomes increasingly PyTorch-first, it trims bloat and doubles down on the PyTorch paths that matter in practice. The result is a cleaner core that unlocks new capabilities through community kernels, quantization, and parallelism plans, while also standardizing model definitions so that architectures supported in transformers are a reference and extend across the wider ecosystem.\\n\\nThis post is a one-time snapshot of a process we repeatedly iterate on towards the same direction: serve the needs of the community. To be up to date with the latest additions to transformers, check the docs and release notes.

For example, Flash Attention was created to optimize the critical attention block that defines the transformers architecture, and is present in many models including most LLMs. By carefully combining all the attention operations inside a single kernel, memory transfers are minimized, memory use is reduced, and speedups can be achieved.\\n\\nThe problem is that all these various kernels are available in separate libraries, which creates a dependency bloat if they were to be added to the transformers library. Furthermore, these kernels are not just Python code, they consist of low-level cuda code, glued together with C++ and exposed through a Python layer. This means they have to be compiled in the target system, which in turn requires whatever build system is required by each kernel library.\\n\\nThe kernels package solves this problem by downloading pre-built binaries of supported kernels from the Hub. You just indicate the kernel you want to use, and kernels will look for a version compatible with your system and download it on first use.\\n\\nCustom Kernels for GPT-OSS\\n\\nGPT-OSS, a Mixture of Experts (MoE) model, is a big user of Kernels from the Hub. It leverages several custom kernels:\\n\\nLiger RMSNorm, used as @use_kernel_forward_from_hub(\"RMSNorm\")`\\n\\nMegablocks MoE kernels: @use_kernel_forward_from_hub(\"MegaBlocksMoeMLP\")\\n\\nFlash Attention 3 with support for attention sinks.\\n\\nMXFP4 triton kernels (covered later)\\n\\nLet\\'s take a look at the first two ones.\\n\\nBehind the scenes, the decorators (1 and 2) simply point to community-contributed kernels. For example, RMSNorm comes from liger_kernels, while the MegaBlocksMoeMLP kernel comes from megablocks. Depending on your device (CUDA or ROCm) and whether you’re training or running inference, the right kernel is pulled in automatically.\\n\\nThis design is both specific and general: the RMSNorm liger kernels are already being reused across multiple models, and the MoE kernel could be applied to future MoEs as well.\\n\\nBecause kernels pulls code from the Hub, you have to opt-in to this feature by passing use_kernels=True in your model instantiation, as shown below. We enable INFO logging in the example so you can easily verify that downloadable kernels are in use.\\n\\nThese kernels are not compatible with mxfp4, so inference will happen in bfloat16 if you use them. Please, benchmark your system for the best combination in memory and throughput that suits your project!\\n\\nfrom transformers import AutoTokenizer, AutoModelForCausalLM import logging logging.basicConfig(level=logging.INFO) model_id = \"openai/gpt-oss-20b\" tokenizer = AutoTokenizer.from_pretrained(model_id) model = AutoModelForCausalLM.from_pretrained( model_id, dtype=\"auto\", device_map=\"auto\", use_kernels=True, )\\n\\nRunning a quick generation yields log messages like\\n\\nINFO:root:Using layer `LigerRMSNorm` from repo `kernels-community/liger_kernels` INFO:root:Using layer `MegaBlocksMoeMLP` from repo `kernels-community/megablocks`\\n\\nFigure 1 shows that, in the system we tested, these kernels work best for larger batch sizes. We always recommend to benchmark any performance-related changes as closely to your production conditions as possible.\\n\\nFigure 1: Benchmarking results of custom kernels\\n\\nYou can explore and play with the benchmarking script here\\n\\nFlash Attention 3\\n\\nOpenAI gpt-oss models use attention sinks, which improves quality and facilitates the use of longer contexts. The vLLM team added this feature to the latest version of Flash Attention (Flash Attention 3), and the resulting custom kernel is available on the Hub. Currently, this kernel is compatible with the Hopper architecture. If you have one, this is the way to enable it:\\n\\nmodel = AutoModelForCausalLM.from_pretrained( model_id, dtype=\"auto\", device_map=\"auto\", + # Flash Attention with Sinks + attn_implementation=\"kernels-community/vllm-flash-attn3\", )\\n\\nMXFP4 Quantization\\n\\nLarge language models are memory-hungry. Quantization reduces memory footprint by storing weights (and sometimes activations) in lower-precision formats. For reference, FP32 uses 32 bits per number and BF16 uses 16. By reducing bit width, we trade some precision for smaller models and faster memory movement.\\n\\nIf you want a visual primer on quantization trade-offs, Maarten Grootendorst’s article is excellent: A Visual Guide to Quantization.\\n\\nWhat is MXFP4\\n\\nFigure 2: The E2M1 format used in the MXFP4 format\\n\\nMXFP4 is a 4-bit floating format with E2M1 layout: 1 sign bit, 2 exponent bits, and 1 mantissa bit, as shown in Figure 2. On its own, E2M1 is very coarse. MXFP4 compensates with blockwise scaling:\\n\\nVectors are grouped into blocks of 32 elements.\\n\\nEach block stores a shared scale that restores dynamic range when dequantizing.\\n\\nInside each block, 4-bit values represent numbers relative to that scale.\\n\\nThis blockwise scheme lets MXFP4 keep range while using very few bits. In practice, GPT-OSS 20B fits in roughly 16 GB of VRAM and GPT-OSS 120B fits in roughly 80 GB when MXFP4 is active, which is the difference between “cannot load” and “can run on a single GPU.” The catch is that matrix multiplies now have to respect block scales. Doing this efficiently at scale requires dedicated kernels.\\n\\nMXFP4 in transformers\\n\\ntransformers now includes native support for MXFP4, leveraging optimized triton (MXFP4) kernels for enhanced performance. This builds on the community-driven kernel distribution discussed earlier, utilizing pre-compiled kernels from the Hub to simplify deployment.\\n\\nKey implementation details:\\n\\nQuantizer logic: Found in the MXFP4 quantizer file, this handles the core quantization process for MXFP4.\\n\\nIntegration hooks: The MXFP4 integration file enables seamless use of MXFP4 within the transformers framework.\\n\\nTo check if a model supports MXFP4, inspect its configuration:\\n\\nfrom transformers import GptOssConfig model_id = \"openai/gpt-oss-120b\" cfg = GptOssConfig.from_pretrained(model_id) print(cfg.quantization_config) # Example output: # { # \\'modules_to_not_convert\\': [ # \\'model.layers.*.self_attn\\', # \\'model.layers.*.mlp.router\\', # \\'model.embed_tokens\\', # \\'lm_head\\' # ], # \\'quant_method\\': \\'mxfp4\\' # }\\n\\nIf \\'quant_method\\': \\'mxfp4\\' is present, the model will automatically use the MXFP4 pathway with Triton kernels when supported.\\n\\nThanks to this pull request, you can fine-tune gpt-oss models and save them directly to the Hub in MXFP4 format, streamlining deployment with optimized performance.\\n\\nRequirements and fallbacks\\n\\nTo run MXFP4 on GPU you need:\\n\\naccelerate, kernels, and triton>=3.4 installed. Note that Pytorch 2.8 already comes with triton 3.4, so you only need to manually install triton if using Pytorch 2.7.\\n\\nNVIDIA GPU with compute capability ≥ 7.5. This goes all the way back to Tesla, so you can run gpt-oss-20b on the free tiers of Google Colab and Kaggle, and on many consumer GPUs.\\n\\nIf these constraints are not met, transformers falls back to a higher-precision path (bfloat16 is used by default), which requires about 4× the memory of MXFP4.\\n\\nThe snippet loads GPT-OSS twice on CUDA: once with Mxfp4Config(dequantize=True) (memory intensive) and once in the default quantized path (memory efficient). Figure 3 shows the amount of used VRAM after each load so you can visualize the savings.\\n\\nFigure 3: Memory requirements for the quantized and dequantized models\\n\\nKernels for MXFP4\\n\\nEfficient MXFP4 requires kernels that understand 32-element blocks and their scales during GEMMs and fused ops. This is where Kernels from the Hub comes in again. transformers automatically pulls in the MXFP4-aware Triton kernels from the community repository when you load a model that needs them. The repository will appear in your local cache and will be used during the forward pass. For the MXFP4 kernels one does not need to use the use_kernels=True parameter like before, it is set to default in transformers.\\n\\nQuick sanity check with the Hugging Face cache CLI, after running gpt-oss-20b on a GPU compatible with the triton MXFP4 kernels:\\n\\nhf cache scan\\n\\nSample output:\\n\\nREPO ID REPO TYPE SIZE ON DISK -------------------------------- --------- ------------ kernels-community/triton_kernels model 536.2K openai/gpt-oss-20b model 13.8G\\n\\nThis indicates the MXFP4 kernels were fetched and are available for execution.\\n\\nLet\\'s run some benchmarks and see how well the MXFP4 kernels perform. In Figure 4, we see that the MXFP4 kernels are even better than the custom MoE and RMSNorm kernels for larger batches.\\n\\nFigure 4: MXFP4 kernel benchmark\\n\\nYou can explore and play with the benchmarking script here\\n\\nTensor Parallelism\\n\\nFigure 5: Explanation of tensor parallelism.\\n\\nTensor Parallelism (TP) splits tensors inside a layer across multiple GPUs (as shown in Figure 5). Each GPU multiplies its shard in parallel, and then partial results are collected using all-gather or all-reduce operations. This reduces per-GPU memory and keeps all GPUs working on the same layer, which improves throughput as sequence length or batch size grow. TP is communication-intensive and generally works best on a single machine with fast intra-node links.\\n\\nWhat this enables in transformers\\n\\ntransformers implements TP directly in from_pretrained. You can start with the predefined plan:\\n\\n# run with: torchrun --nproc-per-node 4 tp_gpt_oss.py import torch from transformers import PreTrainedTokenizerFast, GptOssForCausalLM model_id = \"openai/gpt-oss-120b\" tokenizer = PreTrainedTokenizerFast.from_pretrained(model_id) model = GptOssForCausalLM.from_pretrained( model_id, tp_plan=\"auto\", # built in TP support dtype=\"auto\", ).eval() messages = [ {\"role\": \"system\", \"content\": \"Be concise.\"}, {\"role\": \"user\", \"content\": \"Explain KV caching briefly.\"}, ] inputs = tokenizer.apply_chat_template( messages, add_generation_prompt=True, return_tensors=\"pt\", return_dict=True, reasoning_effort=\"low\", ).to(model.device) with torch.inference_mode(): generations = model.generate(**inputs, max_new_tokens=128) print(tokenizer.decode(generations[0][inputs[\"input_ids\"].shape[-1]:]))\\n\\nIf you don’t have the infrastructure to run the above, you can just spawn a process on our GPUs using Hugging Face Jobs!\\n\\nhf jobs run --detach --flavor l4x4 ghcr.io/astral-sh/uv:debian /bin/bash -c \\\\ \"uv venv .venv --python 3.12 && \\\\ source .venv/bin/activate && \\\\ uv pip install --upgrade torch numpy transformers accelerate triton kernels && \\\\ wget https://huggingface.co/datasets/ariG23498/distributed/raw/main/tp_gpt_oss.py && \\\\ torchrun --nproc-per-node=4 tp_gpt_oss.py\"\\n\\nhf jobs is available for all Hugging Face PRO & Enterprise users.\\n\\nUnder the hood, tp_plan=\"auto\" selects a predefined sharding recipe for each layer and wires the necessary collectives. You can inspect the active plan with print(model._tp_plan) if you want to verify what is being sharded.\\n\\nWhen to reach for TP\\n\\nUse TP when the model is too large for one GPU and you want parallel compute, not only memory placement. TP tends to scale throughput with more GPUs, especially for long sequences or larger batches.\\n\\nIf you are curious about how TP differs from device_map=\"auto\" (memory placement), this short Stack Overflow answer explains the distinction and when to use each.\\n\\nTo learn more about TP, here are two must-read resources:\\n\\ntransformers guide: Tensor parallelism, supported models, plans, and extension points.\\n\\nUltra-Scale Playbook: background on TP and its relationship to other parallelism modes.\\n\\nExpert Parallelism\\n\\nExpert Parallelism (EP) shards experts inside MoE layers across GPUs. Each token is routed to one or a few experts, so only those experts run their feed-forward pass. Since experts are independent MLPs, we can place different experts on different ranks and exchange only the hidden states for the routed tokens. This keeps the matrix multiplies intact on each rank and replaces tensor slicing with routing and collectives.\\n\\nRun with multiple processes using torchrun. EP is enabled via the distributed configuration and works with GPT-OSS MoE layers out of the box in transformers.\\n\\n# run with: torchrun --nproc-per-node 4 ep_gpt_oss.py import torch from transformers import PreTrainedTokenizerFast, GptOssForCausalLM from transformers.distributed import DistributedConfig model_id = \"openai/gpt-oss-120b\" tokenizer = PreTrainedTokenizerFast.from_pretrained(model_id) model = GptOssForCausalLM.from_pretrained( model_id, distributed_config=DistributedConfig(enable_expert_parallel=True), # enabling EP dtype=\"auto\", ).eval() messages = [ {\"role\": \"system\", \"content\": \"Be concise.\"}, {\"role\": \"user\", \"content\": \"Explain KV caching briefly.\"}, ] inputs = tokenizer.apply_chat_template( messages, add_generation_prompt=True, return_tensors=\"pt\", return_dict=True, reasoning_effort=\"low\", ).to(model.device) with torch.inference_mode(): generations = model.generate(**inputs, max_new_tokens=128) print(tokenizer.decode(generations[0][inputs[\"input_ids\"].shape[-1]:]))\\n\\nHere is how you would run using hf jobs\\n\\nhf jobs run --detach --flavor l4x4 ghcr.io/astral-sh/uv:debian /bin/bash -c \\\\ \"uv venv .venv --python 3.12 && \\\\ source .venv/bin/activate && \\\\ uv pip install --upgrade torch numpy transformers accelerate triton kernels && \\\\ wget https://huggingface.co/datasets/ariG23498/distributed/raw/main/ep_gpt_oss.py && \\\\ torchrun --nproc-per-node=4 ep_gpt_oss.py\"\\n\\nWhen you enable Expert Parallelism, Tensor Parallelism is also activated. This means you enjoy the best of both worlds!\\n\\nDynamic Sliding Window Layer & Cache\\n\\nMany recent LLMs use sliding window attention, or a combination of sliding and global attention layers, as a means to save memory and reduce those expensive quadratic matmuls that grow with sequence length. However, the dynamic KV cache implementation in transformers used to continue to allocate space according to sequence length, without looking at the individual attention layers. You could always optimize memory using compilation (meaning, fixed shapes), but that\\'s a separate scenario altogether.\\n\\ntransformers now has a DynamicSlidingWindowLayer and a config‑aware DynamicCache. If the model config declares sliding‑window or hybrid attention (both sliding and global attention layers are used), the cache stops growing past the window for the sliding layers. If you don’t pass the config, behavior stays as before (full, ever‑growing KV as sequence length grows).\\n\\nFor models that only use sliding window layers, such as Mistral 7B, cache memory stops growing when the sequence reaches the window size (4096, in this case). This makes sense, because the sliding layers can\\'t look past the previous 4K tokens anyway.\\n\\nOpenAI gpt-oss alternates between sliding and global attention layers, which results in total KV cache memory being halved, as we\\'ll see, as sequence length increases. This provides us with:\\n\\nMuch lower KV‑cache memory for models with sliding or hybrid attention (e.g. GPT‑OSS). Cache growth plateaus once the window is reached (e.g., 4K for Mistral; 128 for GPT‑OSS sliding layers), instead of scaling linearly with total generated tokens. (GitHub, Transformers)\\n\\nSpeed/latency wins on long prompts/long generations: smaller KV tensors mean lighter attention reads/writes and less memory bandwidth pressure, especially after the window is hit. (This is the central motivation behind sliding‑window/hybrid LLMs.) (AI21, vLLM Blog)\\n\\nHow to use it\\n\\nThe optimized cache is set by default, that means you don\\'t have to make any changes to your existing code. If you want to create the DynamicCache explicitly here is how you would do it:\\n\\nfrom transformers import AutoModelForCausalLM, AutoTokenizer, DynamicCache model_id = \"openai/gpt-oss-20b\" tokenizer = AutoTokenizer.from_pretrained(model_id) model = AutoModelForCausalLM.from_pretrained( model_id, dtype=\"auto\", device_map=\"auto\", ).eval() messages = [ {\"role\": \"system\", \"content\": \"Always respond in riddles\"}, {\"role\": \"user\", \"content\": \"What is the weather like in Madrid?\"}, ] inputs = tokenizer.apply_chat_template( messages, add_generation_prompt=True, return_tensors=\"pt\", return_dict=True, reasoning_effort=\"low\", ).to(model.device) cache = DynamicCache(config=model.config) # create the cache with the model\\'s config generated = model.generate( **inputs, max_new_tokens=500, past_key_values=cache ) print(tokenizer.decode(generated[0][inputs[\"input_ids\"].shape[-1]:]))\\n\\nFigure 6 showcases how much of a difference it makes for us to use the Dynamic KV Cache with sliding window attention.\\n\\nFigure 6: The memory analysis of dynamic cache with sliding window attention\\n\\nContinuous Batching & Paged Attention\\n\\nA typical autoregressive generation process looks like Figure 7. You input the prefill tokens, and the model predicts each new token one after the other until it predicts the EOS (End of Sequence) token.\\n\\nFigure 7: Autoregressive token generation\\n\\nLet’s see what the generation process looks like when we pass a batch of inputs. In Figure 8 you notice that some generations finish off earlier than the others. This mismatch of length underutilizes the GPUs.\\n\\nFigure 8: Static batching of sequences\\n\\nThis type of batching sequences is called static batching. While this is simple and easy to understand, it inherently comes with inefficiencies. Only after each sentence is completely generated can we move on to the next batch.\\n\\nTo bypass this issue, we use dynamic batching (also known as continuous batching). Instead of waiting for all the generation to finish, we schedule incoming requests to the completed generations. That way, as soon as a generation in a batch is complete, we prefill the batch with the next request. The process looks like Figure 9.\\n\\nFigure 9: Continuous Batching of sequences\\n\\nTransformers supports continuous batching with the generate_batch API. This is not meant for production-grade model serving –frameworks like vLLM and SGLang are great at that–, but can be very helpful for evaluation and experimentation. Here is an example script that runs CB end to end on Qwen/Qwen3-4B-Instruct-2507.\\n\\nWe have also performed a benchmark between Continuous Batching and Static Batching with 100 samples. In Figure 9, we note that CB is quite faster than SB.\\n\\nFigure 9: Continuous vs Static Batching Tokens/Second\\n\\nYou can play around with the benchmark here: SB, CB\\n\\nLoad larger models faster\\n\\nWhen you load a large model into your GPU, PyTorch needs to reserve GPU memory for each layer’s weights. Each of these requests (per layer) takes time, and for multi-billion-parameter models it can mean thousands of tiny memory allocations, adding up to a long wait before the model is ready. Instead of asking the GPU for new memory every single time, it can hold on to a big chunk once and then hand out slices from it quickly.\\n\\nPyTorch allocators can do exactly this. The catch is that the allocator only gets fast after you’ve given it some memory to work with. If you don’t “stock the pantry” first, you still end up doing many slow trips to the market. This PR (🎉 #36380) taught transformers to pre-stock the pantry before it starts copying model weights.\\n\\nIt:\\n\\nLooks at the device_map (where each layer will live).\\n\\nPre-allocates a big enough block on each GPU.\\n\\nThen, as layers are copied in, they just slot neatly into this pre-reserved space.\\n\\nYou have to make no changes to your existing code, as this is default behaviour in transformers. If you use device_map=\"auto\" or provide your own device map, your model will now load faster automatically. If you’re running with Tensor Parallel (tp_plan=\"auto\") and torchrun you also benefit from companion changes that make multi-GPU loading smarter.\\n\\nConclusion\\n\\ntransformers moves quickly and it is community-first. The library evolves at the pace of the field because contributors shape it in the open. Pieces added for new models become part of the toolkit and are reused in future integrations.\\n\\nThis velocity enables day-zero integrations like the GPT-OSS series. As the stack becomes increasingly PyTorch-first, it trims bloat and doubles down on the PyTorch paths that matter in practice. The result is a cleaner core that unlocks new capabilities through community kernels, quantization, and parallelism plans, while also standardizing model definitions so that architectures supported in transformers are a reference and extend across the wider ecosystem.\\n\\nThis post is a one-time snapshot of a process we repeatedly iterate on towards the same direction: serve the needs of the community. To be up to date with the latest additions to transformers, check the docs and release notes.

The models feature some novel techniques like MXFP4 quantization, efficient kernels, a brand new chat format, and more. To enable the release of gpt-oss through transformers, we have upgraded the library considerably. The updates make it very efficient to load, run, and fine-tune the models.\\n\\nIn this blog post, we talk about all the upgrades in-depth, and how they become part of the transformers toolkit so other models (current and future) can benefit from them. Providing clean implementations of new methods in transformers also allows the community to quickly understand and adopt them.

This builds on the community-driven kernel distribution discussed earlier, utilizing pre-compiled kernels from the Hub to simplify deployment.\\n\\nKey implementation details:\\n\\nQuantizer logic: Found in the MXFP4 quantizer file, this handles the core quantization process for MXFP4.\\n\\nIntegration hooks: The MXFP4 integration file enables seamless use of MXFP4 within the transformers framework.\\n\\nTo check if a model supports MXFP4, inspect its configuration:\\n\\nfrom transformers import GptOssConfig model_id = \"openai/gpt-oss-120b\" cfg = GptOssConfig.from_pretrained(model_id) print(cfg.quantization_config) # Example output: # { # \\'modules_to_not_convert\\': [ # \\'model.layers.*.self_attn\\', # \\'model.layers.*.mlp.router\\', # \\'model.embed_tokens\\', # \\'lm_head\\' # ], # \\'quant_method\\': \\'mxfp4\\' # }\\n\\nIf \\'quant_method\\': \\'mxfp4\\' is present, the model will automatically use the MXFP4 pathway with Triton kernels when supported.\\n\\nThanks to this pull request, you can fine-tune gpt-oss models and save them directly to the Hub in MXFP4 format, streamlining deployment with optimized performance.\\n\\nRequirements and fallbacks\\n\\nTo run MXFP4 on GPU you need:\\n\\naccelerate, kernels, and triton>=3.4 installed. Note that Pytorch 2.8 already comes with triton 3.4, so you only need to manually install triton if using Pytorch 2.7.\\n\\nNVIDIA GPU with compute capability ≥ 7.5. This goes all the way back to Tesla, so you can run gpt-oss-20b on the free tiers of Google Colab and Kaggle, and on many consumer GPUs.\\n\\nIf these constraints are not met, transformers falls back to a higher-precision path (bfloat16 is used by default), which requires about 4× the memory of MXFP4.\\n\\nThe snippet loads GPT-OSS twice on CUDA: once with Mxfp4Config(dequantize=True) (memory intensive) and once in the default quantized path (memory efficient). Figure 3 shows the amount of used VRAM after each load so you can visualize the savings.\\n\\nFigure 3: Memory requirements for the quantized and dequantized models\\n\\nKernels for MXFP4\\n\\nEfficient MXFP4 requires kernels that understand 32-element blocks and their scales during GEMMs and fused ops. This is where Kernels from the Hub comes in again. transformers automatically pulls in the MXFP4-aware Triton kernels from the community repository when you load a model that needs them. The repository will appear in your local cache and will be used during the forward pass. For the MXFP4 kernels one does not need to use the use_kernels=True parameter like before, it is set to default in transformers.\\n\\nQuick sanity check with the Hugging Face cache CLI, after running gpt-oss-20b on a GPU compatible with the triton MXFP4 kernels:\\n\\nhf cache scan\\n\\nSample output:\\n\\nREPO ID REPO TYPE SIZE ON DISK -------------------------------- --------- ------------ kernels-community/triton_kernels model 536.2K openai/gpt-oss-20b model 13.8G\\n\\nThis indicates the MXFP4 kernels were fetched and are available for execution.\\n\\nLet\\'s run some benchmarks and see how well the MXFP4 kernels perform. In Figure 4, we see that the MXFP4 kernels are even better than the custom MoE and RMSNorm kernels for larger batches.\\n\\nFigure 4: MXFP4 kernel benchmark\\n\\nYou can explore and play with the benchmarking script here\\n\\nTensor Parallelism\\n\\nFigure 5: Explanation of tensor parallelism.\\n\\nTensor Parallelism (TP) splits tensors inside a layer across multiple GPUs (as shown in Figure 5). Each GPU multiplies its shard in parallel, and then partial results are collected using all-gather or all-reduce operations. This reduces per-GPU memory and keeps all GPUs working on the same layer, which improves throughput as sequence length or batch size grow. TP is communication-intensive and generally works best on a single machine with fast intra-node links.\\n\\nWhat this enables in transformers\\n\\ntransformers implements TP directly in from_pretrained. You can start with the predefined plan:\\n\\n# run with: torchrun --nproc-per-node 4 tp_gpt_oss.py import torch from transformers import PreTrainedTokenizerFast, GptOssForCausalLM model_id = \"openai/gpt-oss-120b\" tokenizer = PreTrainedTokenizerFast.from_pretrained(model_id) model = GptOssForCausalLM.from_pretrained( model_id, tp_plan=\"auto\", # built in TP support dtype=\"auto\", ).eval() messages = [ {\"role\": \"system\", \"content\": \"Be concise.\"}, {\"role\": \"user\", \"content\": \"Explain KV caching briefly.\"}, ] inputs = tokenizer.apply_chat_template( messages, add_generation_prompt=True, return_tensors=\"pt\", return_dict=True, reasoning_effort=\"low\", ).to(model.device) with torch.inference_mode(): generations = model.generate(**inputs, max_new_tokens=128) print(tokenizer.decode(generations[0][inputs[\"input_ids\"].shape[-1]:]))\\n\\nIf you don’t have the infrastructure to run the above, you can just spawn a process on our GPUs using Hugging Face Jobs!\\n\\nhf jobs run --detach --flavor l4x4 ghcr.io/astral-sh/uv:debian /bin/bash -c \\\\ \"uv venv .venv --python 3.12 && \\\\ source .venv/bin/activate && \\\\ uv pip install --upgrade torch numpy transformers accelerate triton kernels && \\\\ wget https://huggingface.co/datasets/ariG23498/distributed/raw/main/tp_gpt_oss.py && \\\\ torchrun --nproc-per-node=4 tp_gpt_oss.py\"\\n\\nhf jobs is available for all Hugging Face PRO & Enterprise users.\\n\\nUnder the hood, tp_plan=\"auto\" selects a predefined sharding recipe for each layer and wires the necessary collectives. You can inspect the active plan with print(model._tp_plan) if you want to verify what is being sharded.\\n\\nWhen to reach for TP\\n\\nUse TP when the model is too large for one GPU and you want parallel compute, not only memory placement. TP tends to scale throughput with more GPUs, especially for long sequences or larger batches.\\n\\nIf you are curious about how TP differs from device_map=\"auto\" (memory placement), this short Stack Overflow answer explains the distinction and when to use each.\\n\\nTo learn more about TP, here are two must-read resources:\\n\\ntransformers guide: Tensor parallelism, supported models, plans, and extension points.\\n\\nUltra-Scale Playbook: background on TP and its relationship to other parallelism modes.\\n\\nExpert Parallelism\\n\\nExpert Parallelism (EP) shards experts inside MoE layers across GPUs. Each token is routed to one or a few experts, so only those experts run their feed-forward pass. Since experts are independent MLPs, we can place different experts on different ranks and exchange only the hidden states for the routed tokens. This keeps the matrix multiplies intact on each rank and replaces tensor slicing with routing and collectives.\\n\\nRun with multiple processes using torchrun. EP is enabled via the distributed configuration and works with GPT-OSS MoE layers out of the box in transformers.\\n\\n# run with: torchrun --nproc-per-node 4 ep_gpt_oss.py import torch from transformers import PreTrainedTokenizerFast, GptOssForCausalLM from transformers.distributed import DistributedConfig model_id = \"openai/gpt-oss-120b\" tokenizer = PreTrainedTokenizerFast.from_pretrained(model_id) model = GptOssForCausalLM.from_pretrained( model_id, distributed_config=DistributedConfig(enable_expert_parallel=True), # enabling EP dtype=\"auto\", ).eval() messages = [ {\"role\": \"system\", \"content\": \"Be concise.\"}, {\"role\": \"user\", \"content\": \"Explain KV caching briefly.\"}, ] inputs = tokenizer.apply_chat_template( messages, add_generation_prompt=True, return_tensors=\"pt\", return_dict=True, reasoning_effort=\"low\", ).to(model.device) with torch.inference_mode(): generations = model.generate(**inputs, max_new_tokens=128) print(tokenizer.decode(generations[0][inputs[\"input_ids\"].shape[-1]:]))\\n\\nHere is how you would run using hf jobs\\n\\nhf jobs run --detach --flavor l4x4 ghcr.io/astral-sh/uv:debian /bin/bash -c \\\\ \"uv venv .venv --python 3.12 && \\\\ source .venv/bin/activate && \\\\ uv pip install --upgrade torch numpy transformers accelerate triton kernels && \\\\ wget https://huggingface.co/datasets/ariG23498/distributed/raw/main/ep_gpt_oss.py && \\\\ torchrun --nproc-per-node=4 ep_gpt_oss.py\"\\n\\nWhen you enable Expert Parallelism, Tensor Parallelism is also activated. This means you enjoy the best of both worlds!\\n\\nDynamic Sliding Window Layer & Cache\\n\\nMany recent LLMs use sliding window attention, or a combination of sliding and global attention layers, as a means to save memory and reduce those expensive quadratic matmuls that grow with sequence length. However, the dynamic KV cache implementation in transformers used to continue to allocate space according to sequence length, without looking at the individual attention layers. You could always optimize memory using compilation (meaning, fixed shapes), but that\\'s a separate scenario altogether.\\n\\ntransformers now has a DynamicSlidingWindowLayer and a config‑aware DynamicCache. If the model config declares sliding‑window or hybrid attention (both sliding and global attention layers are used), the cache stops growing past the window for the sliding layers. If you don’t pass the config, behavior stays as before (full, ever‑growing KV as sequence length grows).\\n\\nFor models that only use sliding window layers, such as Mistral 7B, cache memory stops growing when the sequence reaches the window size (4096, in this case). This makes sense, because the sliding layers can\\'t look past the previous 4K tokens anyway.\\n\\nOpenAI gpt-oss alternates between sliding and global attention layers, which results in total KV cache memory being halved, as we\\'ll see, as sequence length increases. This provides us with:\\n\\nMuch lower KV‑cache memory for models with sliding or hybrid attention (e.g. GPT‑OSS). Cache growth plateaus once the window is reached (e.g., 4K for Mistral; 128 for GPT‑OSS sliding layers), instead of scaling linearly with total generated tokens. (GitHub, Transformers)\\n\\nSpeed/latency wins on long prompts/long generations: smaller KV tensors mean lighter attention reads/writes and less memory bandwidth pressure, especially after the window is hit. (This is the central motivation behind sliding‑window/hybrid LLMs.) (AI21, vLLM Blog)\\n\\nHow to use it\\n\\nThe optimized cache is set by default, that means you don\\'t have to make any changes to your existing code. If you want to create the DynamicCache explicitly here is how you would do it:\\n\\nfrom transformers import AutoModelForCausalLM, AutoTokenizer, DynamicCache model_id = \"openai/gpt-oss-20b\" tokenizer = AutoTokenizer.from_pretrained(model_id) model = AutoModelForCausalLM.from_pretrained( model_id, dtype=\"auto\", device_map=\"auto\", ).eval() messages = [ {\"role\": \"system\", \"content\": \"Always respond in riddles\"}, {\"role\": \"user\", \"content\": \"What is the weather like in Madrid?\"}, ] inputs = tokenizer.apply_chat_template( messages, add_generation_prompt=True, return_tensors=\"pt\", return_dict=True, reasoning_effort=\"low\", ).to(model.device) cache = DynamicCache(config=model.config) # create the cache with the model\\'s config generated = model.generate( **inputs, max_new_tokens=500, past_key_values=cache ) print(tokenizer.decode(generated[0][inputs[\"input_ids\"].shape[-1]:]))\\n\\nFigure 6 showcases how much of a difference it makes for us to use the Dynamic KV Cache with sliding window attention.\\n\\nFigure 6: The memory analysis of dynamic cache with sliding window attention\\n\\nContinuous Batching & Paged Attention\\n\\nA typical autoregressive generation process looks like Figure 7. You input the prefill tokens, and the model predicts each new token one after the other until it predicts the EOS (End of Sequence) token.\\n\\nFigure 7: Autoregressive token generation\\n\\nLet’s see what the generation process looks like when we pass a batch of inputs. In Figure 8 you notice that some generations finish off earlier than the others. This mismatch of length underutilizes the GPUs.\\n\\nFigure 8: Static batching of sequences\\n\\nThis type of batching sequences is called static batching. While this is simple and easy to understand, it inherently comes with inefficiencies. Only after each sentence is completely generated can we move on to the next batch.\\n\\nTo bypass this issue, we use dynamic batching (also known as continuous batching). Instead of waiting for all the generation to finish, we schedule incoming requests to the completed generations. That way, as soon as a generation in a batch is complete, we prefill the batch with the next request. The process looks like Figure 9.\\n\\nFigure 9: Continuous Batching of sequences\\n\\nTransformers supports continuous batching with the generate_batch API. This is not meant for production-grade model serving –frameworks like vLLM and SGLang are great at that–, but can be very helpful for evaluation and experimentation. Here is an example script that runs CB end to end on Qwen/Qwen3-4B-Instruct-2507.\\n\\nWe have also performed a benchmark between Continuous Batching and Static Batching with 100 samples. In Figure 9, we note that CB is quite faster than SB.\\n\\nFigure 9: Continuous vs Static Batching Tokens/Second\\n\\nYou can play around with the benchmark here: SB, CB\\n\\nLoad larger models faster\\n\\nWhen you load a large model into your GPU, PyTorch needs to reserve GPU memory for each layer’s weights. Each of these requests (per layer) takes time, and for multi-billion-parameter models it can mean thousands of tiny memory allocations, adding up to a long wait before the model is ready. Instead of asking the GPU for new memory every single time, it can hold on to a big chunk once and then hand out slices from it quickly.\\n\\nPyTorch allocators can do exactly this. The catch is that the allocator only gets fast after you’ve given it some memory to work with. If you don’t “stock the pantry” first, you still end up doing many slow trips to the market. This PR (🎉 #36380) taught transformers to pre-stock the pantry before it starts copying model weights.\\n\\nIt:\\n\\nLooks at the device_map (where each layer will live).\\n\\nPre-allocates a big enough block on each GPU.\\n\\nThen, as layers are copied in, they just slot neatly into this pre-reserved space.\\n\\nYou have to make no changes to your existing code, as this is default behaviour in transformers. If you use device_map=\"auto\" or provide your own device map, your model will now load faster automatically. If you’re running with Tensor Parallel (tp_plan=\"auto\") and torchrun you also benefit from companion changes that make multi-GPU loading smarter.\\n\\nConclusion\\n\\ntransformers moves quickly and it is community-first. The library evolves at the pace of the field because contributors shape it in the open. Pieces added for new models become part of the toolkit and are reused in future integrations.\\n\\nThis velocity enables day-zero integrations like the GPT-OSS series. As the stack becomes increasingly PyTorch-first, it trims bloat and doubles down on the PyTorch paths that matter in practice. The result is a cleaner core that unlocks new capabilities through community kernels, quantization, and parallelism plans, while also standardizing model definitions so that architectures supported in transformers are a reference and extend across the wider ecosystem.\\n\\nThis post is a one-time snapshot of a process we repeatedly iterate on towards the same direction: serve the needs of the community. To be up to date with the latest additions to transformers, check the docs and release notes.

This method mitigates the perceptual mismatch caused by noise schedulers that affect low-resolution images more severely than high-resolution ones. NoiseShift significantly enhances image quality at low resolutions, as demonstrated on models like Stable Diffusion 3, Stable Diffusion 3.5, and Flux-Dev, with improvements in FID scores on datasets such as LAION-COCO and CelebA.

Future parts of the series will explore integration and optimization strategies, including quantization and dynamic shapes, to enhance performance on the Neural Engine.\"}, {'summary': \"OpenAI's GPT-OSS series introduces novel advancements such as MXFP4 quantization, efficient kernels, and a new chat format, significantly enhancing the transformers library's efficiency in loading, running, and fine-tuning models. Performance improvements are evident with PyTorch 2.0's torch.compile, which optimizes kernels for 2–10× gains, and the use of custom kernels like Flash Attention 3, which minimizes memory transfers and speeds up operations. Practical applications include the ability to load larger models faster, with GPT-OSS 20B fitting in 16 GB of VRAM using MXFP4, enabling single GPU deployment. Industry impact is seen in the integration of Tensor and Expert Parallelism, which distribute workloads across GPUs for improved throughput and memory efficiency. The introduction of Dynamic Sliding Window Layer & Cache reduces memory usage for models with sliding or hybrid attention, enhancing speed and latency for long prompts. Continuous Batching further optimizes GPU utilization by dynamically scheduling requests, outperforming static batching. These advancements, driven by community contributions, position transformers as a reference framework for future model implementations and integrations.\"}], 'message': 'Summaries already fit in context (942 tokens).

For instance, A2 may have different camera viewpoints or dif- ferent lighting conditions to A1 (full details of these differences are given in Appendix Section B). We generate a dataset using a physics-based simulator, consisting of one training split and two test splits. The models are only trained on the training split from the simulator for all the evaluations. The training and test-1 splits are sampled from A1, sharing the same nuisance distribution; test-2 is drawn from A2, introducing a distribution shift. The target property values are sampled from a shared range across all splits to ensure consistency. Finally, test-3 consists of real-world videos, used to evaluate generalization beyond simulation.\\n\\n3.1 THE PhysVid DATASETS\\n\\nTo study the dynamic physical properties of elasticity, viscosity, and friction, we construct a dataset for each, containing both synthetic and real-world videos. Synthetic ones are generated with the Genesis simulator (Zhou et al., 2024), and real ones are captured with an iPhone in slow-motion mode or downloaded from the Internet. For each property we have: 10,000 videos for train; 1000 videos for each of test-1 and test-2; and 100 videos for test-3. Sample frames are shown in Figure 1. In the following we describe how each property is realized in the video. Please refer to Appendix Section B for more details of the datasets.\\n\\nElasticity\\n\\nWe study an object’s elasticity by analyzing the motion of a ball dropped onto the ground and its subsequent bounces. In physics, elasticity e is quantified as the ratio of the rebound velocity Vafter impact t0 the impact velocity vbefore impact and also equals ounce/ rop Where hgrop is the dropping height and Apunce 1S the bouncing height. Here and for the following properties, please refer to Appendix Scnr the detailed derivations. These expressions are used for the oracle estimation in Section\\n\\nSynthetic Dataset. All synthetic videos are generated using Genesis (Zhou et al., 2024), with ob- ject’s elasticity as the target property.

Note, here and for the following properties, the ground truth property value is obtained directly from the simulator.\\n\\nReal-World Dataset. The real-world videos are collected from YouTube using the search term “ball bouncing experiments”. Each clip is manually trimmed to include the drop-and-bounce sequence of a single ball. The dataset includes a wide range of materials (e.g., rubber balls, tennis balls, basketballs, balloons, efc), resulting in diverse elasticity values. The ground truth elasticity values for the real sequences are estimated by computing pounce harop: the videos are chosen such that the balls bounce in a fronto-parallel plane, which means that ratios of image heights (differences in y-coordinates) are approximately equal to the ratio of heights in 3D. These image differences are obtained by manual annotation.\\n\\nFigure 1: Examples of the PhysVid dataset.

The viscosity can be reflected by the growth rate of the liquid area on the ground. The viscosity µ is negatively correlated to the liquid area growth rate d(A(t)) , given the controlled liquid density ρ, dt controlled liquid column diameter D, and controlled dropping velocity v of the liquid column when it reaches the ground.\\n\\nSynthetic Dataset.

Since it is challenging to find real-world videos online that provide ground- truth viscosity values while controlling for other relevant physical parameters—such as ρ, D and v, we collected real videos under controlled conditions. We use a funnel with a fixed nozzle diameter to produce a consistent liquid column. A funnel holder allows us to fix the height from which the liquid is poured, thereby controlling the initial velocity v. Ground-truth viscosity values for each liquid are obtained from standard physics reference tables. The selected liquids span a wide range of viscosities, from 1.2 (e.g., coffee) to 225 (e.g., maple syrup), allowing for a diverse and comprehensive evaluation.\\n\\nFriction\\n\\nWe study friction between an object and a surface by observing how the object slows down as it slides with an initial velocity. The dynamic friction coefficient µk is proportional to the (negative) acceleration of the object a.\\n\\nSynthetic Dataset. The synthetic videos are generated using Genesis (Zhou et al., 2024), where the target property is the dynamic friction coefficient at the contacting surface of the object and the ground. Nuisance factors include initial location and initial velocity of the object, camera viewpoint, object appearance, and lighting conditions. The object is of the same size in all videos.\\n\\nReal-World Dataset. While many online videos depict objects sliding on surfaces, they lack ground- truth annotations for friction coefficients. We therefore collect a real video dataset featuring 5 differ- ent objects and 6 surface materials, spanning a wide range of dynamic friction values. Each object is given an initial velocity by sliding it down from a slope and it then slides on a horizontal plane. To obtain ground-truth friction coefficients, we use a spring dynamometer to measure the friction force F for each object-surface pair (by dragging the object at constant speed), and record the object’s weight G. The dynamic friction coefficient is then computed as: µk = F/G.\\n\\n4 INFERRING PHYSICAL PROPERTIES\\n\\nThis section presents the three different ways for inferring dynamic physical properties: an oracle method via classical computer vision techniques (Section 4.1); a visual prompt mechanism for video generative and self-supervised models (Section 4.2); and prompts for MLLMs (Section 4.3).\\n\\n4.1 ORACLE ESTIMATION\\n\\nElasticity. We aim to estimate elasticity from both synthetic and real-world videos. The key visual cue is the relative height of the ball during its drop and subsequent bounce, observed in 3D. As noted earlier, the ratio in 3D can be approximated from their corresponding image-space measurements. This approximation is exact when the motion occurs in a fronto-parallel plane, and remains reason- ably accurate otherwise—since the ratio of lengths between parallel line segments is invariant under affine transformations (Hartley & Zisserman, 2004). Given that perspective effects are minimal in our videos, the affine approximation provides a reliable estimate for elasticity. To automate this process, we extract the ball’s trajectory y(t) from the video and input the sequence of ratios into a GRU network to regress the elasticity. In detail, we segment the ball in each frame and use their centroids as the y-coordinate. From this trajectory, we identify key points: the initial drop position, the first ground contact, and the peak of the first bounce. The resulting trajectory is normalized to the range [0,1], by subtracting the y-coordinate of the first ground contact and dividing by the initial drop height. This normalization not only ensures invariance to viewpoint and scale, but also sim-\\n\\nViscosity\\n\\nWe study the viscosity by observing a liquid column dropping and spreading on the ground. The viscosity can be reflected by the growth rate of the liquid area on the ground. The viscosity µ is negatively correlated to the liquid area growth rate d(A(t)) , given the controlled liquid density ρ, dt controlled liquid column diameter D, and controlled dropping velocity v of the liquid column when it reaches the ground.\\n\\nSynthetic Dataset.

The dynamic friction coefficient is then computed as: µk = F/G.\\n\\n4 INFERRING PHYSICAL PROPERTIES\\n\\nThis section presents the three different ways for inferring dynamic physical properties: an oracle method via classical computer vision techniques (Section 4.1); a visual prompt mechanism for video generative and self-supervised models (Section 4.2); and prompts for MLLMs (Section 4.3).\\n\\n4.1 ORACLE ESTIMATION\\n\\nElasticity. We aim to estimate elasticity from both synthetic and real-world videos. The key visual cue is the relative height of the ball during its drop and subsequent bounce, observed in 3D. As noted earlier, the ratio in 3D can be approximated from their corresponding image-space measurements. This approximation is exact when the motion occurs in a fronto-parallel plane, and remains reason- ably accurate otherwise—since the ratio of lengths between parallel line segments is invariant under affine transformations (Hartley & Zisserman, 2004). Given that perspective effects are minimal in our videos, the affine approximation provides a reliable estimate for elasticity. To automate this process, we extract the ball’s trajectory y(t) from the video and input the sequence of ratios into a GRU network to regress the elasticity. In detail, we segment the ball in each frame and use their centroids as the y-coordinate. From this trajectory, we identify key points: the initial drop position, the first ground contact, and the peak of the first bounce. The resulting trajectory is normalized to the range [0,1], by subtracting the y-coordinate of the first ground contact and dividing by the initial drop height. This normalization not only ensures invariance to viewpoint and scale, but also sim-\\n\\nFigure 2: Oracle methods for physical properties. The objective in each case is to extract a measurement from the sequence that can directly be used to predict the property. For elasticity, we extract the centroid trajectory from segmentation masks, and then normalize the y-coordinates into 0-1; the ratio of bouncing to dropping height over the sequence indicates the elasticity. For viscosity, we calculate the area size in the image via segmentation masks, and then normalize the area sizes by the area in the frame when the liquid first touches the ground; the slope of the normalized area size sequence reflects the viscosity. For friction, we transform to a bird’s eye view (using a homography transformation based on 4 corner points of the top surface of the sliding object), and fit a parabola x = αt2 + βt + c to the transformed trajectory; the parabola coefficient α predicts the friction coefficient. For each video, we show the segmentation for two frames (left → right).\\n\\nplifies learning for the GRU by standardizing the input distribution. We train a GRU, as it is noisy to directly obtain hdrop and hbounce using heuristics (e.g., determining the maximum and minimum points), and in practice a GRU provides a good estimate. The full pipeline is illustrated in Fig- ure 2 (top row). For the absolute prediction, the normalized trajectory is fed into a GRU network, which directly regresses the elasticity value. For the relative comparison, the binary decision score between two videos v1 and v2 is calculated as:\\n\\nwhere e1 and e2 are the estimated elasticities based on height ratios, and σ(·) denotes the sigmoid function.\\n\\nViscosity. The key visual cue for estimating viscosity is the rate at which the liquid spreads on the ground-plane, measured as an area ratio normalized by the initial area of the liquid column. As with elasticity, we approximate perspective using an affine transformation – here of the ground- plane. Since area ratios are invariant under affine transformations (Hartley & Zisserman, 2004), the liquid’s normalized image-space area growth approximates its true normalized ground-plane expansion (in our setup the liquid spreads only within a limited area around the release point, and the camera is distant; consequently an affine viewing approximation is adequate). Specifically, we extract segmentation masks for each frame and compute the liquid’s area over time. This area sequence is normalized by the area in the first frame where the liquid contacts the surface, ensuring invariance to viewpoint and scale. The process is illustrated in Figure 2 (middle row). For absolute prediction, we calculate the slope k of A(t) and use 1/k to represent the viscosity value; For relative comparison, the binary decision score between two videos v1 and v2 is calculated as in Equation 1, where e1 and e2 are the estimated viscosities based on area growth rate.\\n\\nFriction. The key visual cue for estimating dynamic friction is the acceleration of the sliding ob- ject—i.e., how quickly its velocity decreases due to friction—which can be inferred from its position over time. Since the object moves significantly in the video, we do not use an affine approximation, but instead take account of the projective geometry by mapping the object’s motion to a bird’s-eye view, allowing for consistent trajectory analysis. This is achieved by estimating a homography be- tween the image and bird’s eye view (normal to the plane) from the four corners of the object’s top surface (see Figure 2, bottom row). We fit a parabola x = αt2 + βt + c to the transformed top surface trajectory to estimate the acceleration a from the coefficient α, and the coefficient of friction µk = 2α/g. For absolute prediction, we use the estimated µk to represent the friction coefficient value; For relative comparison, the binary decision score between two videos v1 and v2 is calculated as in Equation 1, where e1 and e2 are the estimated friction coefficients based on the transformed object trajectory.\\n\\n(1)\\n\\n4.2 VIDEO GENERATIVE AND SELF-SUPERVISED MODELS\\n\\nVideo Feature Extraction\\n\\nFigure 2: Oracle methods for physical properties.

Similar to the generative setting, we introduce a learnable query vector q to extract the video feature representation P from the ViT tokens via attentive pooling. Although the feature dimension at each ViT layer is the same, we still use a MLP network to map q to generate the query vector of each layer (keeping it similar to the generative setting in terms of MLP network architecture), and use another MLP network to map the output vectors p to a same dimension as the generative setting before average pooling them to get P.

For elasticity and friction, the absolute value prediction is supervised with L1 loss with the ground truth value; For viscosity, as the ground truth values may have very different scales, i.e., from 1e−5 to 1e−2, the absolute value prediction is trained with Log L1 loss, which calculates L1 loss between the log of the predicted value and the log of the ground truth value.\\n\\nRelative Value Prediction.

The oracle estimator performs nearly perfectly on test-1 and test-2, and strongly on test-3, indicating that the task is largely solvable using visual cues, geometry, and physics. Both generative and self-supervised video models achieve strong results on synthetic splits (test-1 and test-2). Notably, they can also generalize well to the real-world split (test-3) for viscosity and elastic- ity, which rely on simple height ratios and expansion. However, friction proves more challenging. Models trained on synthetic data struggle to generalize, likely due to the fact that reliance on visual references (e.g., ground plane grids) is absent in real videos, and due to friction’s inherent complex- ity involving higher-order motion and projective geometry of the viewpoint. To further confirm, we introduce an additional real-world training split for friction videos with disjoint objects and surfaces from the test set (see Appendix Section B.2 for more details). Fine-tuning the visual prompting architecture on this data improves performance on the real test split, as shown by the * values in Table 1. Multimodal large language models (MLLMs), though not working very well with Baseline Prompt (see Appendix Section D), when prompted properly, also perform well, especially on real videos, which are more in-distribution for them – while on synthetic splits, their performance drops significantly. This is likely due to the fact that the models tend to leverage semantic cues rather than visual motion.\\n\\n5.2 RESULTS FOR ABSOLUTE VALUE PREDICTION\\n\\nTable 1 (right) shows results for absolute value prediction across physical properties and methods.

In the first row, we illustrate an example from the elasticity absolute value prediction task. The video generative model, self-supervised model, and MLLMs predict values of 0.83, 0.96, and 1.0, respec- tively—all reasonably close to the ground-truth value of 0.89. In the second row, we present a friction relative value comparison task. The input consists of two videos, where the first exhibits a higher dynamic friction coefficient than the second. Both the video generative model and the MLLM correctly assign high likelihoods to this relationship (0.82 and 1.0, respectively), aligning with the ground truth. In contrast, the self-supervised model incorrectly predicts the reverse and does so with high confidence. Figure 4 (right) shows examples of the scatter plots for the absolute value predic- tion. More specifically, we show the scatter plots of video self-supervised model on the three test splits. It can be observed that the performance degrades from test-1 to test-3, as test-1 is of the same distribution as the synthetic training split, while test-2 is out-of-distribution synthetic test and test-3 is for real evaluation. We provide more scatter plots in Appendix Section F.\\n\\n6 CONCLUSION\\n\\nWe investigate the task of inferring dynamic physical properties—elasticity, viscosity, and fric- tion—from videos. To support this, we introduce a benchmark dataset with ground-truth annota- tions and evaluate a range of video foundation models under both absolute prediction and relative comparison settings. We adopt a simple architecture to extract physical cues from off-the-shelf gen- erative and self-supervised video models, and explore prompting strategies to elicit predictions from MLLMs. Experiments show that generative and self-supervised models have similar performance. MLLMs perform worse overall but improve with more informative prompting, especially on real- world data. However, all models fall short of the oracle, particularly in absolute value prediction. These results highlight the need to enhance physical reasoning in video models—a key direction for future research.\\n\\nTable 1: Results for relative value comparison and absolute value prediction.

To maintain context, models like those in the GPT series must re-process the entire conversation history with every single turn. This \"brute-force\" approach is not only inefficient but also makes interactions prohibitively expensive and slow as dialogues grow longer. The computational cost scales quadratically (O(L2)) with the length of the conversation, a bottleneck that larger context windows don\\'t solve but merely postpone.\\n\\nToday, we\\'re introducing the Reactive Transformer (RxT), a novel architecture detailed in our paper, \"Reactive Transformer (RxT) - Stateful Real-Time Processing for Event-Driven Reactive Language Models\". RxT shifts the paradigm from data-driven, stateless processing to event-driven, stateful computation. It is designed from the ground up to enable real-time, coherent, and economically viable long-form conversations.\\n\\nThe Core Problem: Why Stateless LLMs Struggle with Dialogue\\n\\nImagine having to reread an entire book from the beginning every time you wanted to start a new page. This is essentially how today\\'s LLMs handle conversations. Because they have no inherent memory, context is managed by concatenating the entire dialogue history and feeding it back into the model with each new user query.\\n\\nThis leads to two critical issues:\\n\\nExploding Computational Costs: The total number of tokens processed over a conversation with N turns scales quadratically (O(N2⋅T)). This makes long-running dialogues incredibly expensive, a problem familiar to anyone using LLM APIs for conversational agents.\\n\\nIncreasing Latency: The time it takes to process the initial prompt grows with every turn. This means the model gets slower and less responsive the longer you talk to it, hindering the user experience in real-time applications.\\n\\nWhile architectures like State Space Models (Mamba) or Retrieval-Augmented Generation (RAG) have addressed parts of this problem, they don\\'t solve the core issue for dialogue. SSMs still typically process the full history, and RAG treats memory as an external tool, not an integrated part of the model\\'s reasoning process.\\n\\nA Paradigm Shift: Event-Driven and Asynchronous\\n\\nThe Reactive Transformer (RxT) redefines the entire process by treating each conversational turn as a discrete event. Instead of processing a monolithic history, RxT operates in a continuous, cyclical workflow with a fixed-size internal Short-Term Memory (STM).\\n\\nThe key innovation is its asynchronous operational cycle, which separates response generation from memory consolidation:\\n\\n⚡️ Real-Time Response Generation (Synchronous Phase): When a user sends a query, the Generator-Decoder immediately produces a response. It does this by referencing the user\\'s query and the previous memory state (STMt−1\\u200b). This entire process is lightweight and fast, ensuring minimal user-perceived latency.\\n\\n🧠 Memory Update (Asynchronous Phase): After the response has been sent to the user, the Memory Encoder and Memory Attention network work in the background. They process the complete interaction (both the user\\'s query and the model\\'s answer) and update the memory state to STMt\\u200b.\\n\\nThis decoupling is crucial. The computationally intensive task of consolidating new information into memory happens after the user has already received their response, meaning it adds zero latency to the interaction.\\n\\nThis design provides two transformative benefits:\\n\\nLinear Cost Scaling: The total user-facing cost of a conversation scales linearly (O(N⋅T)) with the number of turns, making long dialogues computationally feasible.\\n\\nConstant, Low Latency: Since response generation depends only on the current query and a fixed-size memory, the inference time remains constant, no matter how long the conversation has been going on.\\n\\nUnder the Hood: The RxT Architecture\\n\\nRxT is an encoder-decoder model, but its components serve unique, specialized roles within its event-driven cycle.\\n\\nGenerator-Decoder: This is the user-facing component responsible for autoregressive text generation. Crucially, each layer includes a Memory Cross-Attention sub-layer, allowing it to query the STM for relevant context from past interactions. To maintain efficiency, it uses Mixture-of-Experts (MoE) layers.\\n\\nMemory Encoder: Its sole purpose is to create a condensed, rich semantic representation of the just-completed interaction (query + answer). This \"Encoded Data\" is then passed to the memory system.\\n\\nAttention-Based Memory System (ABMS): This is the core of RxT\\'s statefulness. The STM is not a log of past tokens but a collection of fixed-size, learnable vectors (memory slots). The Memory Attention network updates these slots by using them as queries to \"seek out\" relevant information from the Encoded Data of the latest interaction. We\\'ve developed several variants, including Interlayer and Gated Self-Attention, to allow for more sophisticated memory consolidation .\\n\\nResidual Gates: To control how much old information is retained and how much new information is written, we use gated residual connections. This helps prevent \"catastrophic forgetting\" and ensures stable learning over many interactions.\\n\\nExperimental Results: Performance and Efficiency\\n\\nWe conducted a series of experiments to validate RxT\\'s architecture, training several models of increasing scale and comparing them against a baseline stateless decoder-only LLM of a comparable size. All models were trained on datasets derived from TinyStories.\\n\\nSuperior Conversational Performance\\n\\nOur results show that architectural specialization pays off. Even our smallest model, RxT-Alpha Nano (12M parameters), significantly outperformed a larger 22M parameter stateless LLM baseline on multi-turn dialogue tasks.\\n\\nPerplexity: The 12M RxT model achieved a perplexity of 2.74, far better than the 22M LLM\\'s 4.37. Our largest model, RxT-Alpha Synthetic (160M), reached a PPL of 2.18.\\n\\nAccuracy: The RxT models consistently achieved ~80-82% next-token prediction accuracy, compared to just 55% for the stateless baseline.\\n\\nCoherence: Using a custom MRL Reward Score to measure conversational quality, all RxT models demonstrated a superior ability to maintain context and coherence over long dialogues compared to the baseline.\\n\\nThese results confirm that a specialized, memory-augmented architecture is far more effective and parameter-efficient for conversational tasks than a generic, monolithic one.\\n\\nConstant Low Latency\\n\\nThe latency benchmark highlights RxT\\'s primary advantage for real-time applications. We measured the prompt processing time over an 8-step dialogue.\\n\\nThe stateless LLM\\'s latency grew steadily with each turn, from 0.09s to over 0.22s, as its context window filled up.\\n\\nRxT\\'s latency remained nearly constant at ~0.06s across all steps, completely independent of the dialogue\\'s history.\\n\\nThis demonstrates RxT\\'s ability to deliver a snappy, responsive user experience that doesn\\'t degrade over time.\\n\\nConclusion and Future Work\\n\\nThe Reactive Transformer offers a new path forward for building truly interactive and scalable conversational AI.
