๐ MMedLM
The official model weights for "Towards Building Multilingual Language Model for Medicine".
๐ปGithub Repo ๐จ๏ธarXiv Paper
๐ Quick Start
The model can be loaded as follows:
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)
โ ๏ธ Important Note
This is a foundation model that has not undergone instruction fine-tuning.
โจ Features
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
๐ Documentation
News
- [2024.2.21] Our pre-print paper is released on ArXiv. Dive into our findings here.
- [2024.2.20] We release MMedLM and MMedLM 2. 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, a multilingual medical corpus containing 25.5B tokens.
- [2023.2.20] We release MMedBench, a new multilingual medical multi-choice question-answering benchmark with rationale. Check out the leaderboard here.
Evaluation on MMedBench
The further pretrained MMedLM 2 showcases its great performance in the medical domain across different languages.
