After five days of chaos triggered by OpenAI's firing of CEO Sam Altman, the executive is set to return to the company, while the board of directors that fired him is to be almost entirely remade. OpenAI said last night that it "reached an agreement in principle for Sam Altman to return to OpenAI as CEO."

Altman had accepted a job on Sunday from Microsoft, a major investor in OpenAI. Microsoft also offered to hire OpenAI's employees, who threatened to resign en masse if Altman wasn't brought back. According to Altman, Microsoft CEO Satya Nadella supported his return to OpenAI.
