Musk accuses OpenAI of abandoning its original non-profit mission to make its AI research results available to everyone. Musk's amended lawsuit names Microsoft, Hoffman and Templeton as defendants, as well as two new plaintiffs: Siobhan Zilis, Neuralink chief executive and former OpenAI board member, and xAI.

In previous complaints, Musk claimed to have donated $44 million to OpenAI because of the company's commitment to making artificial intelligence accessible. But the transition to a commercial structure cancels these promises.

"No objective observer can look at OpenAI today and say it has anything in common with what the company promised to be," Musk's lawyers wrote in the motion. — The plaintiffs respectfully ask the court to maintain the status quo and suspend the deterioration of the defendants' behavior until the final resolution of the case.

OpenAI was founded in 2015 as a non-profit organization and in 2019 converted to a "limited profit" organization, in which the non-profit organization became the governing body for a for-profit subsidiary. OpenAI is currently in the process of becoming a fully commercial corporation.
