OpenAI Ends Model Supply Agreement After SpaceX Acquires Cursor

OpenAI announced that it will terminate its supply agreement for its models to Cursor following SpaceX's acquisition of Cursor. The final service discontinuation date is November 12, 2026, applying the maximum notice period permitted under the contract to provide developers with ample advance notice.

Background and Reasons for Termination

OpenAI made this decision due to a lack of confidence that SpaceX would comply with its terms of service, citing precedents of past contract violations by Elon Musk's companies.

• Twitter Acquisition Case: After Musk acquired Twitter (now part of SpaceX), he violated OpenAI's contract terms.
• xAI Testimony: Earlier this year, Musk admitted under oath that xAI (now part of SpaceX) had violated OpenAI's terms of service.

Future Plans and Developer Support

As OpenAI faces increased responsibility to ensure that next-generation models such as Astra are used in accordance with its terms, it determined that maintaining existing contracts under the changed control environment was difficult. OpenAI expressed respect for its four-year partnership with Cursor and the developer community, stating that it would not spare support for developers affected by this transition.
