On Nov. 17 the artificial intelligence startup OpenAI made the shock announcement that it fired CEO Sam Altman — and reaffirmed that decision on Nov. 19 with the hiring of Twitch co-founder Emmett Shear as the new CEO.

In days between, the tech world reeled, Altman’s colleagues rallied to his side, then-OpenAI president and co-founder Greg Brockman also quit and OpenAI's board of directors held talks to possibly reinstate Altman while facing enormous public backlash from shareholders and employees.

Here’s what’s happened so far.

Ilya Sustekever schedules call with Altman

According to an X (formerly Twitter) post from Brockman, OpenAI chief scientist Ilya Sutskever sent Altman a message on Thursday evening to schedule a meeting for Friday afternoon.

Additionally, he claimed that OpenAI CTO Mira Murati was made aware that Altman would be fired that evening.

So, here's what happened at OpenAI tonight. Mira planned to hire Sam and Greg back. She turned Team Sam over past couple of days. Idea was to force board to fire everyone, which they figured the board would not do. Board went into total silence. Found their own CEO Emmett Shear
