Shunyu Yao
Also known as 姚顺雨
Shunyu Yao is a language-agent researcher whose work connects model reasoning with tools and actions. He studied at Tsinghua's Yao Class and Princeton, and coauthored WebShop, ReAct and Tree of Thoughts, which let language models act in shopping sites, use external information, and explore multiple reasoning paths. He joined OpenAI in 2024 to work on AI agents; his selected work includes the Computer-Using Agent and Deep Research, and he coauthored τ-bench to test agents against domain rules. Since December 2025, he is Tencent's chief AI scientist; by June 2026, he heads the AI Infra and LLM departments and works on Hy3.
