On August 28, 2026, OpenAI published a post titled Our decision on Cursor following its acquisition by SpaceX. In it, OpenAI said it had notified SpaceX that it intended to wind down its contract providing OpenAI models to Cursor, with a proposed shutoff date of November 12, 2026.
What OpenAI said
- OpenAI said the proposed date reflected the maximum notice its contract allowed.
- OpenAI said it would hold the cancellation to the latest date it could while not providing future models to Cursor, and named its model Astra.
- OpenAI said it could not be confident that SpaceX would use its technology within its terms of service, based on its experience with Elon Musk's companies violating contracts.
- OpenAI said Twitter, by then part of SpaceX, broke its contract, and that Musk admitted under oath that xAI, also by then part of SpaceX, violated the terms.
- OpenAI said it had worked with Cursor for nearly four years.
What it means for people building with AI
Cursor users could lose OpenAI models in the editor after the proposed November 12, 2026 shutoff date, and future OpenAI models, including Astra, were not to be provided to Cursor. The move also showed that model access can depend on who owns a tool.
