StackLLaMA: A hands-on guide to train LLaMA with RLHF
LLaMA just got a playbook. Hugging Face drops StackLLaMA—the first open guide to RLHF training that lets anyone build what OpenAI built.

Why it matters
StackLLaMA democratizes reinforcement learning from human feedback (RLHF)—the training technique behind ChatGPT's alignment. By open-sourcing the full pipeline, Hugging Face lowers the barrier for builders to fine-tune and compete with closed models, reshaping who can control model behavior.
