In November 2023, the board of directors at generative AI company OpenAI suddenly, and with no warning, fired its CEO and co-founder Sam Altman, and removed him from his position on the board.

For the next few days, there was chaos at OpenAI as most employees stood by Altman and efforts were made to bring him back. That finally happened five days later, as Altman returned as CEO, while the board members who voted to fire him agreed to depart.

OpenAI said it would conduct an investigation into what happened during those five days, and late on Friday, it announced that the third-party group that ran its investigation had completed its work. As a result, the decision was made to bring back Altman to the company's board. Also, the board "expressed its full confidence" in continuing to keep Altman as OpenAI's CEO and Greg Brockman as its President.

The blog post also announced that three new board members have been added. They are Dr. Sue Desmond-Hellmann, the former CEO of the Bill and Melinda Gates Foundation, Nicole Seligman, the former EVP and General Counsel at Sony, and Fidji Simo, the current CEO of Instacart.

OpenAI said it will add some improvements to how the company is run. That will include adding new corporate governance guidelines, an anonymous whistleblower hotline, and more.
