# MMedLM
[💻Github Repo](https://github.com/MAGIC-AI4Med/MMedLM)   [🖨️arXiv Paper](https://arxiv.org/abs/2402.13963)

The official model weights for "Towards Building Multilingual Language Model for Medicine".


## Introduction
This repo contains MMed-Llama 3, a multilingual medical foundation model with 8 billion parameters. MMed-Llama 3 builds upon the foundation of Llama 3 and has been further pretrained on MMedC, a comprehensive multilingual medical corpus. This further pretraining enhances the model's medical-domain knowledge.

The model underwent further pretraining on MMedC with the following hyperparameters:
- Iterations: 15000
- Global batch size: 512
- Cutoff length: 8192
- Learning rate: 2e-5
  
The model can be loaded as follows:
```py
import torch
from transformers import AutoTokenizer, AutoModelForCausalLM
tokenizer = AutoTokenizer.from_pretrained("Henrychur/MMed-Llama-3-8B")
model = AutoModelForCausalLM.from_pretrained("Henrychur/MMed-Llama-3-8B", torch_dtype=torch.float16)
```

-  Note that this is a foundation model that has not undergone instruction fine-tuning.
## News
[2024.2.21] Our pre-print paper is released ArXiv. Dive into our findings [here](https://arxiv.org/abs/2402.13963).

[2024.2.20] We release [MMedLM](https://huggingface.co/Henrychur/MMedLM) and [MMedLM 2](https://huggingface.co/Henrychur/MMedLM2). With an auto-regressive continues training on MMedC, these models achieves superior performance compared to all other open-source models, even rivaling GPT-4 on MMedBench.

[2023.2.20] We release [MMedC](https://huggingface.co/datasets/Henrychur/MMedC), a multilingual medical corpus containing 25.5B tokens.

[2023.2.20] We release [MMedBench](https://huggingface.co/datasets/Henrychur/MMedBench), a new multilingual medical multi-choice question-answering
benchmark with rationale. Check out the leaderboard [here](https://henrychur.github.io/MultilingualMedQA/).

## Evaluation on MMedBench
The further pretrained MMedLM 2 showcast it's great performance in medical domain across different language.
