About me
I am a third-year PhD student at Peking University, advised by incredible Prof. Di He. Currently, I am an intern at ByteDance Seed working on coding agents. I have also previously interned at Microsoft Research Asia and DP Technology. I earned my bachelor’s degree at UESTC.
Recent Focus
My recent work focuses on enhancing the coding agent capabilities of LLMs. Selected projects include:
2025.9~Now: I am the core contributor to the 01 web generation capabilities of the Seed 2.0 Code model series. Collaborating with several great colleagues, we built a complete and mature optimization pipeline from scratch for 01 web generation, enabling continuous iteration to enhance model performance through SFT data synthesis, RL optimization, reward modeling, and novel in-house innovations to prevent reward hacking.
2025.2~2025.8: Led the development of SWE-Swiss, a 32B open-weight model that achieves top-tier performance on SWE-bench Verified. [Notion] [code]
