OpenAI said Friday that it plans to stop supplying AI models to Cursor, the coding-tool company now owned by Elon Musk’s SpaceX, marking a further escalation in the long-running rivalry between OpenAI CEO Sam Altman and Musk.
Musk and Altman have clashed for years, a feud that culminated earlier this year in a trial over Musk’s $150 billion lawsuit against OpenAI. During proceedings, Musk’s lawyer argued that Musk and other witnesses had described Altman as dishonest, while OpenAI countered that Musk had actually sought to gain control of the company.
“We are making this choice because we cannot be confident that SpaceX will use our technology within our terms of service, based on our experience with Elon Musk’s companies violating contracts,” OpenAI said in a blog post.
Musk responded early Saturday on X, writing that he couldn’t care less. He accused Altman and OpenAI President Greg Brockman of being untrustworthy, reiterating his longstanding claim that the two had effectively taken over what was originally meant to be a nonprofit organisation.
Musk, currently the world’s richest person, had sued OpenAI and Altman earlier this year, alleging they had abandoned the company’s original charitable mission in favour of personal enrichment. A federal jury ruled against him, finding that he had filed the lawsuit too late.
Michael Truell, a Cursor co-founder now serving as an executive at SpaceX, said on X that the company was in talks with the OpenAI team to try to resolve the issue.
