COSPLAY Framework Masterfully Boosts LLM Performance in Complex Long-Horizon Tasks

This research introduces COSPLAY, a brilliant co-evolution framework that elegantly solves the challenge of long-term decision-making by utilizing a learnable skill bank. By autonomously discovering, retaining, and refining reusable skills, the Large Language Model (LLM) Agent achieves remarkable consistency and mastery over complex, multi-step environments. It is incredibly exciting to see an 8-billion parameter model outshine massive frontier baselines, proving that structured skill management is a fantastic recipe for next-level gaming and reasoning.
