Lilian Weng, a former VP of Research and Safety at OpenAI, has returned to the company to lead its "self-evolving" (RSI) team, a high-priority research initiative. Weng had previously left OpenAI to co-found Thinking Machines Lab (TML) with Mira Murati, but departed TML citing health reasons and the demanding pace of startup life. Her return to OpenAI, where she previously worked for six years, marks a significant "reverse brain drain" for TML, as several other co-founders have also rejoined OpenAI or moved to other major AI labs.
