Elon Musk’s xAI Accuses Ex-Engineer of Stealing Grok Secrets for OpenAI

Elon Musk’s artificial intelligence venture, xAI, recently filed a lawsuit against former engineer Xuechen Li. They accuse him of stealing proprietary trade secrets related to its advanced Grok chatbot. The lawsuit, filed in a California federal court on Thursday, claims Li took highly sensitive information about “cutting-edge AI technologies with features superior to ChatGPT.” xAI alleges he then brought these secrets to OpenAI, a direct competitor, earlier in August. OpenAI is not named as a defendant in this case.
