OpenAI cuts off Cursor

OpenAI is ending model supply to Cursor after the AI coding tool’s acquisition by SpaceX, turning a developer-workflow partnership into a live example of how tightly frontier model access is being used as competitive leverage. Cursor depends on high-quality models for code completion, refactoring and agentic software tasks, so losing OpenAI access could force a rapid shift toward rival providers or in-house models. The twist is the buyer: SpaceX gives Elon Musk another strategic surface in the AI stack, linking aerospace, infrastructure and developer tools. For enterprise customers, the episode is a reminder that model availability can change abruptly when ownership, rivalry or platform risk changes.
