Former OpenAI CEO Sam Altman and ex-President Greg Brockman visited the company's San Francisco HQ on Sunday, following an invitation from interim CEO Mira Murati. While Altman is considering a comeback at OpenAI, he's also contemplating starting a new AI project, according to reports. His recent dismissal sent ripples through the tech world, where he was a prominent figure in generative AI. OpenAI has not publicly addressed these events.
