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.
