About Me
I'm Sicheng Fan, a Master's student at Fudan University, working on GUI Agents/Computer-Use Agents and Reinforcement Learning. I also serve as the Technical Lead at WebAgentLab community and as an AI Research Intern at LongCat Group, Meituan.
My research focuses on building Computer-Use Agents, utilizing Vision-Language Models (VLMs) for cross-platform task automation, to achieve the next generation of Computer-Use Agents. Recent work includes WebChain (CVPR 2026, the largest web interaction trajectory dataset) and WebFactory (ICLR 2026, an automated RL training framework for GUI agents).
I actively contribute to open source and aim to advance the GUI agent field through shared research and tools. Feel free to reach out for collaboration!
