On Wednesday, OpenAI announced that Sam Altman has officially returned to the ChatGPT-maker as CEO—accompanied by Mira Murati as CTO and Greg Brockman as president—resuming their roles from before the shocking firing of Altman that threw the company into turmoil two weeks ago. Altman says the company did not lose a single employee or customer throughout the crisis.

"I have never been more excited about the future. I am extremely grateful for everyone’s hard work in an unclear and unprecedented situation, and I believe our resilience and spirit set us apart in the industry," wrote Altman in an official OpenAI news release. "I feel so, so good about our probability of success for achieving our mission."

In the statement, Altman formalized plans that have been underway since last week: ex-Salesforce co-CEO Bret Taylor and economist Larry Summers have officially begun their tenure on the "new initial" OpenAI board of directors. Quora CEO Adam D’Angelo is keeping his previous seat on the board. Also on Wednesday, previous board members Tasha McCauley and Helen Toner officially resigned. In addition, a representative from Microsoft (a key OpenAI investor) will have a non-voting observer role on the board of directors.
