San Francisco-based OpenAI has announced that its ousted leader, Sam Altman, will be returning to the company as CEO. The decision comes after a days-long power struggle that has shocked the tech industry and highlighted the conflicts surrounding the safe development of artificial intelligence. Altman was fired by OpenAI's board last week, but following negotiations, an agreement has been reached for his return. The new board of directors will be led by Bret Taylor, former co-CEO of Salesforce, with Larry Summers, former US Treasury Secretary, and Adam D'Angelo, CEO of Quora, also joining. This new board replaces the previous one that fired Altman, which included D'Angelo. The exact reasons for Altman's dismissal have not been made public, leading to internal conflict and pressure for the board's resignation from both employees and investors. Microsoft, which has a significant investment in OpenAI and rights to its technology, moved quickly to hire Altman and another co-founder, Greg Brockman, who had resigned in protest. This move by Microsoft further exacerbated the tensions within OpenAI, with nearly all of its employees threatening to leave if Altman was not reinstated. One of the board members who participated in Altman's firing, Ilya Sutskever, later expressed regret and joined the call for the board's resignation. Microsoft CEO Satya Nadella expressed openness to Altman returning to OpenAI as long as governance issues were resolved. Altman expressed his excitement about returning to OpenAI and building on the partnership with Microsoft. OpenAI, originally founded as a nonprofit with the goal of safely developing artificial general intelligence, later became a for-profit business. It remains to be seen if the board's structure will change with the appointment of new members. Microsoft's support for Altman and Brockman's return has been crucial in the resolution of the power struggle at OpenAI. The company's employees, who have been closely following the developments, expressed relief and celebrated the return to normalcy. OpenAI is now valued at over $80 billion and has secured new funding led by Thrive Capital. Microsoft has pledged to continue partnering with OpenAI in the future.
