SynthAgent is a framework for adapting web agents to any new environments using synthetic supervision. It efficiently synthesizes diverse user tasks by categorized exploration. Then, it refines these tasks during trajectory collection to mitigate hallucinations. After collection, it refines the trajectories to enhance the data quality. Finally, it utilizes refined data to fine-tune the agent, improving the performance in the target new environment.
