Billionaire entrepreneur Elon Musk on Tuesday moved to dismiss his lawsuit in California state court accusing ChatGPT maker OpenAI and its CEO Sam Altman of abandoning the startup’s original mission of developing artificial intelligence for the benefit of humanity and not for profit.

Attorneys for Musk asked the court to dismiss the lawsuit, originally filed in February, without giving a reason for the move, according to a filing in San Francisco Superior Court.

OpenAI and an attorney for Musk did not immediately respond to requests for comment about the dismissal of the lawsuit.

Musk dismissed his case without prejudice, which means he could refile it at another time.

Attorneys for OpenAI had said Musk’s claims in the lawsuit “rest on convoluted – often incoherent – factual premises.”
