The Atropos release by @NousResearch is a major milestone in reinforcement learning for AI.
RL is very different from fine tuning. Fine tuning teaches an LLM to mimic fixed input/output examples. Reinforcement learning has the model interact and explore via trial-and-error feedback, adjusting its behavior to optimize long term, multi-step goals rather than just static accuracy.
You’ve seen us mention RL recently a lo
