FrontierThe story, in brief
Putting RL back in RLHF
Hugging Face just revived the 'RL' in RLHF. Here's why that matters for model training.

Why it matters
A new training methodology (RLOO) addresses inefficiencies in reinforcement learning from human feedback, a core technique for aligning modern LLMs. This could reduce training costs and improve model quality for anyone building frontier models.
