Elon Musk sues OpenAI and CEO Sam Altman for putting profits above humanity

Elon Musk is suing OpenAI and its chief executive Sam Altman, alleging the start-up betrayed its original promise of working to benefit humanity when it forged a multibillion-dollar alliance with Microsoft. The lawsuit filed in San Francisco on Thursday said Altman and OpenAI's co-founder Greg Brockman had initially pledged to make an open-source, non-profit company, and that its pursuit of profit constituted a breach of contract. The company had kept the design of GPT-4, its most advanced AI model, "a complete secret", said Musk's lawyers. Musk co-founded OpenAI in 2015, but stepped down from its board in 2018. He also runs electric vehicle maker Tesla and rocket maker SpaceX, and bought Twitter for 44bn in October 2022.
