Le fine-tuning resout ce probleme. Un cabinet d avocats peut fine-tuner sur sa jurisprudence. Un e-commerce peut fine-tuner sur ses fiches produits. Un medecin peut fine-tuner sur ses notes cliniques.<\/p>\n<h2>Les techniques de fine-tuning<\/h2>\n<p><strong>LoRA<\/strong> (Low-Rank Adaptation) est la technique la plus populaire. Elle ne modifie que 1 a 5% des poids du modele, ce qui reduit drastiquement les besoins en VRAM et en temps de calcul. Un fine-tuning LoRA d un modele 7B prend 2 a 4 heures sur une seule <a href='\/es\/recommends\/rtx-4090\/'>RTX 4090<\/a>.<\/p>\n<p><strong>QLoRA<\/strong> va encore plus loin en quantifiant le modele en 4 bits pendant l entrainement. Resultat : vous pouvez fine-tuner un modele 13B sur une <a href='\/es\/recommends\/rtx-4070\/'>RTX 4070 avec 16 Go de VRAM<\/a>.<\/p>\n<h2>Les outils<\/h2>\n<p>Hugging Face Transformers + PEFT est la stack standard. Axolotl simplifie le processus avec des fichiers YAML. Unsloth promet un entrainement 2x plus rapide avec 60% moins de VRAM.<\/p>\n<h2>Materiel minimum<\/h2>\n<p>Pour LoRA sur un modele 7B : <a href='\/es\/recommends\/rtx-4070\/'>RTX 4070 Ti 16 Go<\/a> + <a href='\/es\/recommends\/ram-ddr5\/'>32 Go RAM DDR5<\/a>. Pour QLoRA sur un modele 70B : <a href='\/es\/recommends\/rtx-5090\/'>RTX 5090 32 Go<\/a>.
