Two Thinking Machines Lab Cofounders Are Leaving to Rejoin OpenAI

The news is a blow for Thinking Machines Lab. Two narratives are already emerging about what happened. Thinking Machines cofounders Barret Zoph and Luke Metz are leaving the fledgling AI lab and rejoining OpenAI, the ChatGPT-maker announced on Thursday. OpenAI's CEO of applications, Fidji Simo, shared the news in a memo to staff Thursday afternoon. The news was first reported on X by technology reporter Kylie Robison, who wrote that Zoph was fired for "unethical conduct."
