Sam Altman will return as CEO of OpenAI, overcoming an attempted boardroom coup that sent the company into chaos over the past several days. The company just tweeted that it has an “agreement in principle” for Altman to return alongside a new board composed of Bret Taylor, Larry Summers, and Adam D’Angelo. D’Angelo is a holdover from the previous board.

Altman’s return is even more shocking than his sudden exit on Friday. OpenAI’s nonprofit board seemed resolute in its initial decision to remove Altman, shuffling through two CEOs in three days to avoid reinstating him. Meanwhile, the employees of OpenAI revolted, threatening to defect to Microsoft with Altman and co-founder Greg Brockman if the board didn’t resign.

During the whole saga, the board members who opposed Altman withheld an actual explanation for why they fired him, even under the threat of lawsuits from investors. On Sunday, a key member of the board, Ilya Sutskever, flipped back to Altman’s camp, leaving the remaining three board members more vulnerable.
