## Model Description

MedMistral-CPT-SFT-7B is a French medical language model based on Mistral-7B-v0.1, adapted for medical domain applications through a combined approach of Continual Pre-Training (CPT) followed by Supervised Fine-Tuning (SFT). 

## Model Details

- **Model Type**: Causal Language Model
- **Base Model**: Mistral-7B-v0.1
- **Language**: French
- **Domain**: Medical/Healthcare
- **License**: Apache 2.0
- **Paper**: [Adaptation des connaissances médicales pour les grands modèles de langue : Stratégies et analyse comparative](https://aclanthology.org/2025.jeptalnrecital-taln.3/)

## Training Details

### Continual Pre-Training (CPT)
- **Dataset**: NACHOS corpus (opeN crAwled frenCh Healthcare cOrpuS)
  - **Size**: 7.4 GB of French medical texts
  - **Word Count**: Over 1 billion words (1,088,867,950 words)
  - **Sources**: 24 French medical websites
- **Training Duration**: 2.8 epochs
- **Hardware**: 32 NVIDIA H100 80GB GPUs
- **Training Time**: 12 hours
- **Optimizer**: AdamW
- **Learning Rate**: 2e-5
- **Weight Decay**: 0.01
- **Batch Size**: 16 with gradient accumulation of 2

### Supervised Fine-Tuning (SFT)
- **Dataset**: 30K French medical question-answer pairs
  - 10K native French medical questions 
  - 10K translated medical questions from English resources
  - 10K generated questions from French medical texts
- **Method**: DoRA (Weight-Decomposed Low-Rank Adaptation)
- **Training Duration**: 10 epochs
- **Hardware**: 1 NVIDIA A100 80GB GPU
- **Training Time**: 75 hours
- **Rank**: 16
- **Alpha**: 16
- **Learning Rate**: 2e-5
- **Batch Size**: 4


## Computational Impact

- **Total Training Time**: 87 hours (12h CPT + 75h SFT)
- **Carbon Emissions**: 11.78 kgCO2e (9.86 + 1.92)


## Ethical Considerations

- **Medical Accuracy**: This model is for research and educational purposes only. All outputs should be verified by qualified medical professionals
- **Bias**: Training data may contain biases present in medical literature and online medical resources

Bien que certaines recherches remettent en question le pr{\'e}-entra{\^i}nement adaptatif (DAPT) dans le contexte m{\'e}dical en anglais, nous montrons que l{'}adaptation au domaine peut {\^e}tre efficace sous certaines conditions. En prenant comme exemple l{'}adaptation au domaine m{\'e}dical en fran{\c{c}}ais, nous comparons de mani{\`e}re syst{\'e}matique le pr{\'e}-entra{\^i}nement continu (CPT), l{'}affinage supervis{\'e} (SFT) et une approche combin{\'e}e (CPT suivi de SFT). Nos r{\'e}sultats indiquent que l{'}adaptation d{'}un mod{\`e}le g{\'e}n{\'e}raliste {\`a} de nouvelles donn{\'e}es dans le domaine m{\'e}dical offre des am{\'e}liorations notables (taux de r{\'e}ussite de 87{\%}), tandis que l{'}adaptation suppl{\'e}mentaire de mod{\`e}les d{\'e}j{\`a} familiaris{\'e}s avec ce domaine procure des b{\'e}n{\'e}fices limit{\'e}s. Bien que CPT+SFT offre les meilleures performances globales, SFT-seul pr{\'e}sente des r{\'e}sultats solides et requiert moins de ressources mat{\'e}rielles."
