Elon Musk sues OpenAI and CEO Sam Altman for abandoning mission

Musk co-founded OpenAI in 2015, but stepped down from its board in 2018.

Elon Musk has sued ChatGPT-maker OpenAI and its chief executive Sam Altman, among others, saying they had abandoned the company's original mission to develop artificial intelligence for the benefit of humanity not profit.

The lawsuit filed late on Thursday said Altman and OpenAI's co-founder Greg Brockman originally approached Musk to make an open source, non-profit company.
