A trial that may shape the future of OpenAI enters its final stages on Thursday, as lawyers for Elon Musk try to convince a jury to hold the ChatGPT maker's leaders responsible for transforming the nonprofit into a vehicle to enrich themselves. Closing arguments are scheduled in the Oakland, California, federal court in Musk's lawsuit against OpenAI and its CEO, Sam Altman. Musk is suing OpenAI and Altman for breach of charitable trust and unjust enrichment, accusing them of "stealing a charity" by straying from OpenAI's founding mission to build safe AI that would benefit humanity.
