OpenAI Chief Executive Officer Sam Altman was cleared of any wrongdoing that would have mandated being fired from the company late last year, according to a report based on a monthslong investigation into the events leading up to his brief ouster. WilmerHale, the law firm that conducted the inquiry, found that the board's decision to fire Altman was a "consequence of a breakdown in the relationship and loss of trust between the prior Board and Mr. Altman," the artificial intelligence startup said Friday. It did not arise from concerns about product safety, the pace of development, or OpenAI's finances, it said. Altman is rejoining the company's board following the findings, the artificial intelligence startup said. OpenAI's board is also adding Sue Desmond-Hellmann, who previously was head of the Bill and Melinda Gates Foundation; Nicole Seligman, an ex-Sony Entertainment executive; and Instacart CEO Fidji Simo.

Following Sam Altman's rollercoaster of a return as OpenAI's CEO, the company announced that it will now include Microsoft as a non-voting observer on its board. The question remains as to why the firm's largest investor wasn't on its board in the first place, but this seems to be somewhat addressed for now, at least. Altman is joined by co-founder Greg Brockman who resumes his role as President, whereas Mira Murati, who very briefly served as interim CEO throughout the drama, will return to her role as CTO. The announcement also confirms a new board consisting of former Salesforce CEO Bret Taylor (chair), former Clinton Treasury Secretary Larry Summers, and original member Adam D'Angelo, who is also Quora's co-founder and CEO. It was earlier rumored that Altman's exit was partly influenced by D'Angelo's seeming conflict of interest, as OpenAI was developing a potential competitor to Quora's Poe service -- the latter offers OpenAI's ChatGPT and GPT-4, along with several other text-generating AI models.

Over five chaotic days that transfixed Silicon Valley and beyond, the world's leading artificial intelligence company, OpenAI, appeared to be on the verge of imploding in a power struggle. The maker of ChatGPT, the sensational chatbot, had a mission to safely develop smarter-than-human AI. But that mission looked in jeopardy on Friday when OpenAI's non-profit board of directors fired Altman, suggesting he had been dishonest in his communications with them. To many spectators, the future of not just AI but also humanity hung in the balance. Finally late on Tuesday night, after three CEO changes and a full-court press by Microsoft, the board gave Altman his old job back.
