Sam Altman and Greg Brockman join Microsoft, Emmett Shear appointed CEO of OpenAI


  • Added statement from Sam Altman and Greg Brockman
  • Added information about the leadership team of Microsoft’s Advanced AI Research Team, which includes GPT-4 Lead Jakub Pachocki.

The OpenAI drama takes another unexpected turn: Sam Altman will not return as CEO, but will join Microsoft instead. His successor is former Twitch CEO Emmett Shear.

Microsoft CEO Satya Nadella personally announced his latest hiring move: Former OpenAI CEO Sam Altman and former OpenAI VP and co-founder Greg Brockman, both of whom were just fired from OpenAI on Friday, are forming a new “Advanced AI Research” team for Microsoft.

“We look forward to moving quickly to provide them with the resources needed for their success,” Nadella wrote. The Microsoft CEO is said to have played a pivotal role in the negotiations over the weekend.

Nadella holds out the prospect of great freedom for Altman. He is to become CEO of Microsoft’s new AI group and “setting a new pace of innovation.”



“We’ve learned a lot over the years about how to give founders and innovators space to build independent identities and cultures within Microsoft,” Nadella writes.

GPT-4 lead joins Microsoft

Altman and Brockman comment on the Microsoft move on Twitter: “The mission continues.” Brockman says he wants to build something new and “incredible.” In addition to Brockman and Altman, the leadership team of Microsoft’s new AI venture includes GPT-4 chief Jakub Pachocki, long-time OpenAI researcher Szymon Sidor, and OpenAI’s head of AI preparedness Aleksander Madry.

The new interim CEO of OpenAI will be former Twitch CEO Emmett Shear, as first reported by The Information. He replaces CTO Mira Murati, who was only named interim CEO on Friday and sided with Altman and Brockman over the weekend. Her future is still unknown (Update: Murati posted on that “OpenAI is nothing without its people,” implying that she will not stay with OpenAI and may follow Altman and Brockman).

Microsoft remains committed to its partnership with OpenAI and looks forward to working with the new OpenAI leadership team, Nadella said. However, he is “extremely excited” that Altman and Brockman are joining Microsoft. Reading between the lines, those words seem carefully chosen.

Altman’s return fails due to Sutskever’s AI safety concerns

Altman was surprisingly fired by the OpenAI board on Friday, presumably due to disagreements between the board and the CEO over AI safety.


Shear wrote on over the summer.

Over the weekend, it appeared that Altman, with the support of the OpenAI team and investors, would win the power struggle and return as CEO, while the board would leave.

But then came the next surprise move by the OpenAI board: they pulled Emmett Shear out of the hat. As a result, dozens of OpenAI employees are said to have submitted their resignations on Sunday evening.

Microsoft is likely to see a large influx of new AI researchers in the near future. Some OpenAI employees are already posting on Twitter that “OpenAI is nothing without its people,” implying that they’ll be leaving and possibly following Altman and Brockman to Microsoft. These people include CTO Mira Murati and COO Brad Lightcap.

Considering that OpenAI recently put tens of millions of dollars on the table to poach AI experts from Google, this could even be a deal for Nadella. Google and Meta are also likely to benefit from OpenAI’s voluntary downsizing. History will show whether Sutskever’s safety concerns are justified.
