A federal judge dismissed a lawsuit on Monday by Elon Musk's artificial intelligence company xAI that accused rival Sam Altman's OpenAI of stealing trade secrets for chatbots. U.S. District Judge Rita Lin in San Francisco said xAI failed to show that OpenAI induced former xAI senior engineer Xuechen Li to divulge confidential information related to its Grok chatbot, or that OpenAI engineers knew Li might have disclosed any. Lin dismissed the lawsuit with prejudice, saying it would be "futile" to continue. She dismissed an earlier version in February. The amended complaint focused on a presentation that Li gave while OpenAI was recruiting him, but the judge said asking job candidates to discuss their prior work was routine. Monday's decision is Musk's second legal loss against OpenAI in four weeks. On May 18, a federal jury ruled against Musk in his $150 billion lawsuit accusing OpenAI and Altman of "stealing a charity." OpenAI said on Monday: "This baseless lawsuit was never anything more than yet another front in Mr. Musk's ongoing campaign of harassment." Li is being sued separately by xAI and has denied wrongdoing.
