Elon Musk filed a lawsuit against OpenAI and its CEO Sam Altman on Monday, claiming that the company prioritized money and commercial interests over the public good.

Musk's latest lawsuit is an attempt to challenge the firm he co-founded in 2015. He claims that once OpenAI's technology began to change generative artificial intelligence, Altman "flipped the narrative and proceeded to cash in."

OpenAI and Musk did not immediately reply to Reuters' requests for comment.

The lawsuit seeks a court ruling that OpenAI's license to Microsoft to utilize its AI models is null and invalid. Musk also claims that OpenAI's language models fall beyond the limits of the company's cooperation with Microsoft.

OpenAI has a license agreement with Microsoft, under which the tech behemoth spends billions of dollars in the firm in exchange for the use of its huge language models in computing services.

Musk dismissed a previous lawsuit against OpenAI and Altman in June, alleging that they had abandoned the startup's initial objective of developing artificial intelligence for the sake of mankind rather than profit.

Musk's attorneys had urged a California state court to dismiss the claim, which had been filed in February, without offering a rationale. In the February lawsuit, Musk stated that OpenAI's three founders initially committed to work on AI in a way that would "benefit humanity."
