    Progress Advantage: A New Method for Evaluating LLM Agents

    Researchers have introduced 'progress advantage,' a novel method for evaluating LLM agents that leverages reinforcement learning post-training. This approach eliminates the need for costly, dedicated reward model training by deriving step-level scoring directly from the RL process. The method has demonstrated effectiveness across various applications, outperforming existing confidence-based baselines and even trained reward models.
