In a dramatic turn of events at OpenAI, the chief executive, Sam Altman, was unexpectedly fired following a significant announcement about the future of artificial intelligence. The board cited Altman's failure to communicate consistently as the reason for his dismissal, sending shockwaves through Silicon Valley.

Altman's termination unfolded rapidly after a message from Ilya Sutskever, OpenAI's chief scientist, asking for a Google Meet discussion the next day. In a subsequent call, Altman learned about his firing, and shortly after, OpenAI's chair and president, Greg Brockman, was also removed from the board. Altman's replacement, Mira Murati, stepped in as interim CEO.

The abrupt change prompted investors to rally for Altman's return, emphasizing his pivotal role in OpenAI. Despite initial resistance, efforts were underway to bring Altman and others, including key researchers, back to the company.

Altman's presence at OpenAI's headquarters and subsequent failed talks hinted at a tumultuous negotiation period. Emmett Shear was appointed the third CEO in three days, leading to Nadella announcing Altman and Brockman's recruitment for a new advanced AI research team at Microsoft.

Monday witnessed staff discontent evolving into open revolt, with the majority of OpenAI's 770 employees threatening mass resignation unless Altman and Brockman were reinstated, leading to board restructuring. The board, facing internal and external pressure, saw Altman inching closer to a return.

A breakthrough was reached as OpenAI announced an agreement in principle for Altman's return, involving a revamped initial board chaired by Bret Taylor, along with Larry Summers and Adam D'Angelo. An independent investigation into Altman's departure is expected, with reports emerging of safety concerns related to a new AI model called "Q*.

Founded in 2015 with a mission focused on developing safe and beneficial artificial general intelligence (AGI), OpenAI's recent upheaval underscores the challenges in navigating the dynamic AI landscape. Altman, who reportedly sought a new board as a condition for his return, signaled efforts to mend divisions within the company on Thanksgiving day.
