OpenAI Ends Access to Cursor AI Models by November 2026

OpenAI will terminate developer access to its AI models through Cursor, which is now owned by SpaceX, with the final access date set for November 12, 2026. OpenAI cited concerns about SpaceX's compliance with terms of service based on past experiences. Cursor co-founder Michael Truell noted that OpenAI models represent approximately 5% of the platform's user traffic. This decision could impact Cursor’s operations and its negotiations with OpenAI, raising questions about future AI model access for developers and potential market implications.
