Elon Musk has initiated a lawsuit against OpenAI, seeking $134 billion in damages over the company's transition to a for-profit model. The trial commenced on April 27 at the federal court in Oakland, California, with jury selection underway and opening statements anticipated on Tuesday. Musk claims OpenAI breached its original nonprofit commitment and demands the reversal of its for-profit conversion and the removal of certain executives. The lawsuit has sparked a public exchange on social media platform X, where OpenAI dismissed the claims as baseless, while Musk criticized OpenAI's CEO Sam Altman, referring to him as "Scam Altman." The trial's liability phase is expected to continue until mid-May, as both parties present their arguments in court.
