Lianmin Zheng
MetaResearch Scientist
Zheng co-developed SGLang, which speeds up language models by reusing work across requests that share the same opening text.[1] He helped build Chatbot Arena, where people compare anonymous chatbot answers side by side,[2] and worked on Vicuna and FastChat, which made open chat models easier to run and test.
