OpenAI announced on Tuesday that it has reached an agreement with Sam Altman to reinstate him as CEO, just a few days after his dismissal, putting an end to the intense debate surrounding the future of this core AI startup. In addition to Altman's return, OpenAI has also agreed in principle to partially restructure its board of directors. Former Salesforce co-CEO Bret Taylor and former US Treasury Secretary Larry Summers will join Quora CEO and current board member Adam D'Angelo. When the board dismissed Altman on Friday, they did not provide many details, only stating that he lacked transparency and that the board needed to uphold OpenAI's mission of developing AI that benefits humanity. It is worth noting that this reinstatement comes as a sudden reversal within 24 hours. Sam Altman had already finalized his plans to join Microsoft at the invitation of CEO Satya Nadella. With Altman confirming his return to OpenAI, Microsoft's plans will once again undergo changes. The agreement to reinstate Altman opens up a potential new era for this startup company.
