OpenAI Cuts Off AI Model Access to Cursor Amid Escalating Musk-Altman Feud
8/31/2026, 2:08:13 AM
Core Event
OpenAI announced that it will cease providing its AI models to Cursor, the coding-tool platform now owned by Elon Musk’s SpaceX. The decision was presented as a response to concerns that SpaceX might use the technology in ways that violate OpenAI’s terms of service.
Background & Context
The move follows a long-standing rivalry between OpenAI CEO Sam Altman and Musk. Earlier this year, Musk filed a $150 billion lawsuit alleging that Altman and OpenAI had “stolen an open-source nonprofit” by abandoning the company’s original nonprofit mission. A federal jury later ruled the suit was filed too late, rejecting Musk’s claim. The legal battle intensified the public feud, with both sides exchanging accusations of contract breaches and untrustworthiness.
Official Statements & Responses
OpenAI explained in a blog post that its choice reflects a lack of confidence in SpaceX’s compliance with its service terms, citing prior experiences of contract violations by Musk’s companies. Musk responded on X (formerly Twitter) with a terse “I couldn’t care less,” labeling Altman and OpenAI President Greg Brockman as “untrustworthy” and reiterating his claim that they “stole an open source nonprofit.” Michael Truell, a co-founder of Cursor and now a SpaceX executive, said on X that the two firms were in talks to resolve the dispute. Anthropic, a rival AI firm with an existing partnership with SpaceX, announced plans to increase compute capacity for its Claude models within Cursor, signaling a shift in support.
