Microsoft hires former OpenAI CEO Sam Altman

Microsoft is hiring former OpenAI CEO Sam Altman and co-founder Greg Brockman. Altman was fired from OpenAI on Friday, after the board said it “no longer has confidence in his ability to continue leading OpenAI.” After a weekend of negotiations to potentially bring Altman back to OpenAI, Microsoft CEO Satya Nadella announced both Sam Altman and Greg Brockman will be joining Microsoft’s new advanced AI research team.

“We’re extremely excited to share the news that Sam Altman and Greg Brockman, together with colleagues, will be joining Microsoft to lead a new advanced AI research team,” says Nadella. “We look forward to moving quickly to provide them with the resources needed for their success.”

Altman’s Microsoft hiring comes just hours after negotiations with OpenAI’s board failed to bring him back as OpenAI CEO. Instead, former Twitch CEO and co-founder Emmett Shear has been named as interim CEO, according to a source speaking to The Verge. He will take over from Mira Murati, who was named interim OpenAI CEO following Altman’s shock firing on Friday. OpenAI hasn’t confirmed Shear’s appointment, but given Microsoft’s hiring of Altman it can’t be far away from announcing a new leadership structure.

Altman had been negotiating to return as OpenAI CEO, but OpenAI’s four-person board refused to step down and let him return, according to multiple sources speaking to The Verge.

Former OpenAI CEO Sam Altman had reportedly been pitching custom, Nvidia-rivaling AI Tensor Processing Unit (TPU) chips to investors recently — according to The New York Times. The TPU project was codenamed “Tigris,” attracting a number of prominent venture firms and even interest from Microsoft, according to Bloomberg.

Microsoft has now formed a new advanced AI research team that will include Altman and Brockman. It comes just a week after Microsoft announced it has built its own custom AI chip that can be used to train large language models and potentially avoid a costly reliance on Nvidia. Microsoft has also built its own Arm-based CPU for cloud workloads. Both custom silicon chips are designed to power its Azure data centers.

At the time, Altman said OpenAI had been working with Microsoft to refine and test the Maia AI chip with its own models. Microsoft was quick to play down its AI chip’s impact on a close Nvidia partnership, but the Maia GPU is part of a series and the company is already working on a second generation.

Microsoft still has a “multibillion dollar investment” in OpenAI, rumored to be worth around $10 billion. Microsoft is the exclusive cloud partner for OpenAI, and Microsoft’s cloud services power all OpenAI workloads across products, API services, and research.
