Lilian Weng is returning to OpenAI after a brief period at Thinking Machines Lab, according to a report by The Information. An OpenAI spokesperson confirmed the move.
Weng was described as a researcher who cofounded Thinking Machines Lab alongside former OpenAI chief technology officer Mira Murati. Her return to OpenAI comes shortly after she announced that she was leaving the startup earlier this week.
The development marks another notable personnel shift in the fast-moving artificial intelligence sector, where senior researchers and founders continue to move between major labs and newer ventures. In this case, the change brings Weng back to OpenAI after helping launch Thinking Machines Lab.
While further details about her role were not included in the report, the update underscores OpenAI’s continued connection to key figures who have also played important roles in newer AI companies.
