  • Native agentic search reasoning model using ReAct framework towards autonomous information seeking agency and Deep Research-like model.
  • We introduce a four-stage training paradigm comprising browsing data construction, trajectory sampling, supervised fine-tuning for effective cold start, and reinforcement learning for improved generalization, enabling the agent to autonomously acquire autonomous search and reasoning skills.
  • Our data-centric approach integrates trajectory-level supervision fine-tuning and reinforcement learning (DAPO) to develop a scalable pipeline for training agentic systems via SFT or RL.
  • WebDancer achieves a Pass@3 score of 61.1% on GAIA and 54.6% on WebWalkerQA.
