On Thursday evening local time, Tesla CEO Elon Musk filed a lawsuit in San Francisco Superior Court against OpenAI and its CEO Sam Altman for breach of contract. Musk said in the lawsuit that Altman and OpenAI violated an agreement when the artificial intelligence research company was founded to develop technology to benefit humanity rather than profit. Musk claimed that OpenAI's recent relationship with Microsoft undermined the company's original commitment to public, open source general artificial intelligence.
