New RewardFlow method enhances LLM agentic reasoning with dense rewards

Researchers have developed RewardFlow, a novel method for estimating state-level rewards in agentic reinforcement learning with large language models. This approach constructs state graphs to capture trajectory topology, enabling topology-aware propagation for estimating state contributions to success. RewardFlow provides dense, annotation-free rewards that significantly improve performance across various agentic benchmarks, outperforming prior methods in success rates and accuracy while demonstrating superior robustness and training efficiency.
