Andrew Tulloch, a star AI researcher, confirmed his departure in a message to employees on Friday, according to people familiar with the matter.

“Andre has decided to pursue a different path for personal reasons,” a spokeswoman for Thinking Machines Lab said in a statement.

Tulloch is a leading researcher in the field of artificial intelligence and previously worked at Meta for 11 years. He left in 2023 to join Open AI for a stint before co-founding Thinking Machines Lab alongside Murati at the start of this year.

The hire is the latest recruiting coup for Meta, which has wound down its hiring spree from its headiest days, as it shifts focus to organizing its new talent-dense AI teams and pursuing the invention of what it calls superintelligence.
