LLM inference in C/C++
整合 MTP (Multi-Token Prediction) + TurboQuant,推理速度起飞!提升幅度 2-5 倍。
✅ Vision 多模态已修复:MTP 模式现已完美支持图像输入,多模态 + 推测解码同时启用不再崩溃。
✅ MTP + TurboQuant 完美融合:同时享受 MTP 推测解码的加速和 TurboQuant KV Cache 压缩的显存节省。
⚠️ 模型要求:必须配合内置 MTP 头部的 GGUF 文件使用(如 Qwen3.6-27B-Q4_K_P_mtp.gguf),普通 GGUF 无法启用 MTP。
| 特性 | 说明 |
|---|---|
| MTP 推测解码 | 每步预测多个 token,推理吞吐提升 2-5 倍 |
| TurboQuant KV Cache | -ctk q8_0 -ctv turbo3 非对称压缩,相比 F16 节省 76% 显存 |

该模板专为 llama.cpp 的 minijinja 引擎深度优化,解决了官方模板 9 大缺陷,以下是其在 llama.cpp 环境下的核心优势:
| 优势 | 说明 |
|---|---|
| C++ 引擎原生兼容 | 彻底移除 Python 专属语法(|items、|safe),使用字典直接取值 + is iterable 替代,minijinja 零错误渲染 |
| 智能自动思考(Auto-Thinking) | 自动判断用户输入长度:短问题(≤30 字符)跳过思考 → 秒回;长问题(≥300 字符)强制思考 → 深度推理。阈值可通过 auto_think_short_threshold / auto_think_force_threshold 自定义 |
| 思考开关标签 | 在 system / user 消息中插入 <|think_off|> 或 <|think_on|> 即可实时切换推理模式,标签在渲染时自动移除,模型完全感知不到 |
</thinking> 幻觉恢复 |
Qwen 3.6 有时会输出 </thinking> 而非 response,模板自动检测两种闭合标签并动态分割,防止推理流中断 |
| 思考未闭合自动修复 | 模型在 thinking 块中直接调用 tool 时(未输出 response),模板自动注入闭合标签,防止 XML 标签污染工具调用 |
| Tool Call 参数完美兼容 | 支持 string / object 两种参数格式,多层嵌套 JSON 正常渲染,-ctk q4_1 -ctv q4_1 缓存下依然稳定 |
| 多轮工具调用(Agent 友好) | 正向遍历检测 multi-step tool chain,无用户查询时优雅回退而非崩溃,适配 OpenCode、Docker Agent 等框架 |
| 对话中 system 消息 | 官方模板在非首条 system 消息时直接崩溃;本模板按时间顺序渲染,兼容所有 agent 框架的中间指令注入 |
developer 角色支持 |
完整映射 OpenAI API 的 developer 角色 |
| Generation Prompt 精细控制 | 模板结尾根据 enable_thinking 状态精确输出 thinking\n(启用思考)或 thinking\n\n response\n\n(快速回答),引导模型输出格式 |
关键参数:搭配
--reasoning auto --reasoning-format deepseek使用,llama.cpp 可自动解析模板输出的 thinking 块并分离显示,实现类似 DeepSeek 的推理过程可视化。

Getting started with llama.cpp is straightforward. Here are several ways to install it on your machine:
- Install
llama.cppusing brew, nix or winget - Run with Docker - see our Docker documentation
- Download pre-built binaries from the releases page
- Build from source by cloning this repository - check out our build guide
Once installed, you'll need a model to work with. Head to the Obtaining and quantizing models section to learn more.
Example command:
# Use a local model file
llama-cli -m my_model.gguf
# Or download and run a model directly from Hugging Face
llama-cli -hf ggml-org/gemma-3-1b-it-GGUF
# Launch OpenAI-compatible API server
llama-server -hf ggml-org/gemma-3-1b-it-GGUFThe main goal of llama.cpp is to enable LLM inference with minimal setup and state-of-the-art performance on a wide
range of hardware - locally and in the cloud.
- Plain C/C++ implementation without any dependencies
- Apple silicon is a first-class citizen - optimized via ARM NEON, Accelerate and Metal frameworks
- AVX, AVX2, AVX512 and AMX support for x86 architectures
- RVV, ZVFH, ZFH, ZICBOP and ZIHINTPAUSE support for RISC-V architectures
- 1.5-bit, 2-bit, 3-bit, 4-bit, 5-bit, 6-bit, and 8-bit integer quantization for faster inference and reduced memory use
- Custom CUDA kernels for running LLMs on NVIDIA GPUs (support for AMD GPUs via HIP and Moore Threads GPUs via MUSA)
- Vulkan and SYCL backend support
- CPU+GPU hybrid inference to partially accelerate models larger than the total VRAM capacity
The llama.cpp project is the main playground for developing new features for the ggml library.

The Hugging Face platform hosts a number of LLMs compatible with llama.cpp:
You can either manually download the GGUF file or directly use any llama.cpp-compatible models from Hugging Face or other model hosting sites, by using this CLI argument: -hf <user>/<model>[:quant]. For example:
llama-cli -hf ggml-org/gemma-3-1b-it-GGUFBy default, the CLI would download from Hugging Face, you can switch to other options with the environment variable MODEL_ENDPOINT. The MODEL_ENDPOINT must point to a Hugging Face compatible API endpoint.
After downloading a model, use the CLI tools to run it locally - see below.
llama.cpp requires the model to be stored in the GGUF file format. Models in other data formats can be converted to GGUF using the convert_*.py Python scripts in this repo.
The Hugging Face platform provides a variety of online tools for converting, quantizing and hosting models with llama.cpp:
- Use the GGUF-my-repo space to convert to GGUF format and quantize model weights to smaller sizes
- Use the GGUF-my-LoRA space to convert LoRA adapters to GGUF format (more info: ggml-org/llama.cpp#10123)
- Use the GGUF-editor space to edit GGUF meta data in the browser (more info: ggml-org/llama.cpp#9268)
- Use the Inference Endpoints to directly host
llama.cppin the cloud (more info: ggml-org/llama.cpp#9669)

If your issue is with model generation quality, then please at least scan the following links and papers to understand the limitations of LLaMA models. This is especially important when choosing an appropriate model size and appreciating both the significant and subtle differences between LLaMA models and ChatGPT:
