- [May 13, 2024] 🔥LLaVA-Med v1.5 is out! It is not only significantly better (see the evaluation results.) but also much easier to use: no more delta weights! Now you can directly load our model from the 🤗 Hub. The original LLaVA-Med (i.e., v1.0.0) codebase has been moved to Archive.
- [Nov 8, 2023] LLaVA-Med is open-sourced under the MSR release policy. Huge thanks to commitment of the team, and patience of the community.
- [Sept, 2023] LLaVA-Med is accepted in NeurIPS 2023 Datasets and Benchmarks Track, as a spotlight presentation.
- [June 1, 2023] 🔥 We released LLaVA-Med: Large Language and Vision Assistant for Biomedicine, a step towards building biomedical domain large language and vision models with GPT-4 level capabilities. Checkout the paper
LLaVA-Med was initialized with the general-domain LLaVA and then continuously trained in a curriculum learning fashion (first biomedical concept alignment then full-blown instruction-tuning). We evaluated LLaVA-Med on standard visual conversation and question answering tasks.

'default': {
'endpoint': "INSERT YOUR AZURE OPENAI ENDPOINT HERE",

}- GPT-4 inference was only tested using Azure OpenAI API. If you are using OpenAI API, you need to replace llava/eval/llm.py (line 55) AsyncAzureOpenAI with AsyncOpenAI.
In llava/eval/eval_multimodal_chat_gpt_score.py (line 55), replace with your GPT-4 model deployment id if necessary:

sh download_data.shLarge Language and Vision Assistant for bioMedicine (i.e., “LLaVA-Med”) is a large language and vision model trained using a curriculum learning method for adapting LLaVA to the biomedical domain. It is an open-source release intended for research use only to facilitate reproducibility of the corresponding paper which claims improved performance for open-ended biomedical questions answering tasks, including common visual question answering (VQA) benchmark datasets such as PathVQA and VQA-RAD.
The data, code, and model checkpoints are intended to be used solely for (I) future research on visual-language processing and (II) reproducibility of the experimental results reported in the reference paper. The data, code, and model checkpoints are not intended to be used in clinical care or for any clinical decision making purposes.
The primary intended use is to support AI researchers reproducing and building on top of this work. LLaVA-Med and its associated models should be helpful for exploring various biomedical vision-language processing (VLP ) and vision question answering (VQA) research questions.
Any deployed use case of the model --- commercial or otherwise --- is out of scope. Although we evaluated the models using a broad set of publicly-available research benchmarks, the models and evaluations are intended for research use only and not intended for deployed use cases. Please refer to the associated paper for more details.
This model builds upon PMC-15M dataset, which is a large-scale parallel image-text dataset for biomedical vision-language processing. It contains 15 million figure-caption pairs extracted from biomedical research articles in PubMed Central. It covers a diverse range of biomedical image types, such as microscopy, radiography, histology, and more.
This model was developed using English corpora, and thus may be considered English-only. This model is evaluated on a narrow set of biomedical benchmark tasks, described in LLaVA-Med paper. As such, it is not suitable for use in any clinical setting. Under some conditions, the model may make inaccurate predictions and display limitations, which may require additional mitigation strategies. In particular, this model is likely to carry many of the limitations of the model from which it is derived, LLaVA.
Further, this model was developed in part using the PMC-15M dataset. The figure-caption pairs that make up this dataset may contain biases reflecting the current practice of academic publication. For example, the corresponding papers may be enriched for positive findings, contain examples of extreme cases, and otherwise reflect distributions that are not representative of other sources of biomedical data.
