OpenAI Cuts Off Cursor After SpaceX Deal, Citing Musk's Contract Record
OpenAI is winding down its model supply deal with Cursor, with a November 12 shutoff after SpaceX acquired the AI coding startup. The reason is blunt: Musk's companies, per OpenAI, have broken contracts before, from Twitter's post-takeover breach to xAI's admitted misuse of OpenAI data. Cursor developers get the maximum notice possible, but the precedent is the story: a model maker publicly cutting off a flagship tooling partner over a change of control.
