OpenAI co-founder John Schulman, who left AI startup Anthropic last week after a mere five months, is reportedly joining former OpenAI CTO Mira Murati’s secretive new startup, per Fortune.
It’s not clear what Schulman’s role there will be. Fortune wasn’t able to learn that information, and Murati has been tight-lipped about the venture since she left OpenAI in September. But one source did reveal to Fortune that Murati has recruited additional ex-OpenAI staff, including Christian Gibson, who had been serving on OpenAI’s supercomputing team.

Murati was reportedly in talks to raise over $100 million for her company in October.
Credited as one of the leading architects of ChatGPT, Schulman left OpenAI last August for Anthropic. He posted about the decision on X, saying it stemmed from a desire to deepen his focus on AI alignment — the science of ensuring AI behaves as intended — and engage in more hands-on technical work.
