OpenAI moves to pull its models from Cursor after SpaceX deal

OpenAI plans to wind down the contract that lets Cursor offer its models after SpaceX acquired the AI coding platform. Cursor is an editor built around AI assistance, so the decision would remove one supplier of the models developers can use inside the product—not shut down Cursor itself. OpenAI has proposed November 12, 2026, as the cutoff and says it will provide no future models during the wind-down. It says it lacks confidence that SpaceX will follow its terms, citing prior dealings with Elon Musk’s companies; Cursor says OpenAI models handle about 5% of its user traffic and that talks are continuing.
