ChatGPT maker OpenAI says it has agreed a deal for Sam Altman to return as chief executive after he was ousted by its board.
The agreement “in principle” involves a new board being installed, the company said.
In a post on X, OpenAI said: “We have reached an agreement in principle for Sam Altman to return to OpenAI as CEO”.
“We are collaborating to figure out the details. Thank you so much for your patience through this.”
It followed a threatened mutiny by OpenAI staff.
The vast majority of them said they would quit and work for Microsoft if the board did not resign and if Mr Altman and his ally and company president Greg Brockman, who left in solidarity with Mr Altman, were not reinstated.
The pair had been hired to work at Microsoft, OpenAI’s biggest investor, on a new artificial intelligence (AI) research project.
The new board of directors, which operates on a not-for-profit basis, unlike conventional boards, will include the former US Treasury Secretary and economics professor, Larry Summers.
It will be chaired by the former CEO of Salesforce and co-creator of Google maps, Bret Taylor, with the CEO of question and answer site Quora, Adam D’Angelo also joining the board.
OpenAI’s board operates on a non-commercial basis, unlike the company, as it was originally founded as a not-for-profit with the goal of building safe and beneficial AI “for the benefit of humanity”.
Mr Brockman said of his return, which came on Tuesday night west coast America time, that he was “getting back to coding tonight”.
Mr Altman said, “I love OpenAI, and everything I’ve done over the past few days has been in service of keeping this team and its mission together.”
“When I decided to join Microsoft on Sunday evening, it was clear that was the best path for me and the team.
“With the new board and with Satya’s [the CEO of Microsoft’s] support, I’m looking forward to returning to OpenAI, and building on our strong partnership with Microsoft.”
The reason for Mr Altman’s sacking on Friday night remains unclear.
The board had said “was not consistently candid in his communications with the board”.
But in a letter to the board, employees said, “Despite many requests for specific facts for your allegations, you have never provided any evidence,” it read.
