Musk, who runs electric vehicle maker Tesla (NASDAQ:TSLA), rocket maker SpaceX and social media platform X, decided to try to seize control of OpenAI from Altman and the other founders in late 2017, aiming to convert it into a commercial entity in partnership with Tesla, utilizing the automaker's supercomputers, said one source with knowledge of the situation.
Altman and others resisted, and Musk resigned, saying he wanted to focus on Tesla's AI projects. He announced his exit to OpenAI staff in February 2018 during a meeting at which Musk called for OpenAI to increase its development speed, which one researcher called reckless, the source said.
