OpenAI to cut off AI models for SpaceX-owned Cursor, escalating feud with Musk
OpenAI said the move follows trust concerns and will not provide future models to the coding startup, including its coming Astra model.
- OpenAI said it plans to end its supply of AI models to Cursor, the coding platform recently acquired by Elon Musk’s SpaceX, further intensifying the long-running dispute between Musk and OpenAI CEO Sam Altman.
- OpenAI cited concerns that SpaceX and other Musk-owned companies may not comply with its terms of service, pointing to alleged past contractual violations involving X and xAI.
- The termination is scheduled to take effect on November 12, 2026, with OpenAI saying it is giving Cursor the maximum notice allowed under their agreement.
- Cursor co-founder Michael Truell said discussions with OpenAI were continuing, while the company has indicated that OpenAI models account for only a small portion of its overall platform traffic.
- The move comes weeks after SpaceX completed its roughly $60 billion acquisition of Cursor’s parent company Anysphere and follows years of legal and business tensions between Musk and Altman.
