Microsoft hires Sam Altman 3 days after OpenAI fired him as CEO

Microsoft announced Monday that it has hired Sam Altman, the co-founder of ChatGPT maker OpenAI, after he was unexpectedly pushed out of the company days earlier in a corporate shakeup that shocked the artificial intelligence world.

Microsoft CEO Satya Nadella wrote on X, formerly known as Twitter, that Microsoft was “extremely excited” that Altman and OpenAI co-founder Greg Brockman, along with other managers from the AI company, would join Microsoft to lead a “new advanced AI research team.”

Nadella also said the software maker, the largest investor in OpenAI, looked “forward to getting to know” OpenAI’s new chief executive, former Twitch leader Emmett Shear, who was named to replace Altman.
