-# P14 — Qwen3-1.7B LoRA (sanity)
+# P14 - Qwen3-1.7B LoRA adapters
+
+Ce dépôt contient des **adapters LoRA** (PEFT) entraînés sur Windows (RTX 4050 6GB) pour le POC de triage médical.
+
+## Contenu
+
+- dapters/sft/ : adapter après SFT (instruction-tuning)
+- dapters/dpo/ : adapter après DPO (préférences), en partant de l'adapter SFT
+
+## Données
 
-Adapter LoRA issu d'un **run de validation très court** (sanity check) pour vérifier que l'entraînement fonctionne sur Windows + GPU.
+- Dataset principal : cyrille-elie/CHSA-Triage-Medic-Full-Dataset (licence MIT, fr/en)
+- Le dataset complet est géré séparément (dépôt dataset privé dans ce projet).
 
-- Base : Qwen/Qwen3-1.7B-Base
-- Séquence courte (max_seq_length=64) et max_steps=20
+## Avertissement
 
-Ce repo sert à valider le workflow de publication. Le modèle final SFT/DPO sera publié séparément.
+POC éducatif. Ne remplace pas un avis médical.

+# Model Card for qwen3-1.7b-dpo_from_sft_lowvram
+
+This model is a fine-tuned version of [Qwen/Qwen3-1.7B-Base](https://huggingface.co/Qwen/Qwen3-1.7B-Base).
+It has been trained using [TRL](https://github.com/huggingface/trl).
+
+## Quick start
+
+```python
+from transformers import pipeline
+
+question = "If you had a time machine, but could only go to the past or the future once and never return, which would you choose and why?"
+generator = pipeline("text-generation", model="None", device="cuda")
+output = generator([{"role": "user", "content": question}], max_new_tokens=128, return_full_text=False)[0]
+print(output["generated_text"])
+```
+
+## Training procedure
+
+ 
+
+
+
+This model was trained with DPO, a method introduced in [Direct Preference Optimization: Your Language Model is Secretly a Reward Model](https://huggingface.co/papers/2305.18290).
