How Elon Musk left OpenAI, according to Greg Brockman

Greg Brockman testified that Elon Musk quit OpenAI in 2017 after failing to secure full control of a planned for-profit arm.

According to Brockman, Musk became angry when other co-founders rejected his demand for control.

Musk then stopped regular donations and left the board within months.

The old dispute has resurfaced in Musk’s current lawsuit over OpenAI’s future and governance.
