New SCOPE framework enhances LLM agent performance in reinforcement learning

Researchers have developed SCOPE, a novel framework for Selective Critical-Step On-Policy Self-Distillation designed to improve the performance of LLM agents in reinforcement learning tasks. This method refines the learning process by analyzing agent trajectories, generating step-specific skills, and applying distillation only at selected error steps. Experiments on ALFWorld and WebShop benchmarks show significant improvements, with models like Qwen2.5-3B achieving high success rates and outperforming existing methods such as SEED and GRPO, particularly on unseen tasks.
