Research Paper
Core Innovation
This paper presents WebSailor, which uniquely combines synthetic high-uncertainty task generation with a novel RL algorithm, DUPO, to train open-source agents that reduce uncertainty systematically. This approach bridges the performance gap between open-source and proprietary agentic systems on complex benchmarks. It integrates structured sampling, information obfuscation, and efficient reinforcement learning to achieve superior reasoning capabilities.
