OpenAI plans to cut Cursor off from its models in November

OpenAI plans to stop supplying its models to Cursor, now owned by SpaceX, with a proposed shutoff on 12 November. The date is not final.

On 28 August 2026, OpenAI said it told SpaceX it intends to wind down its contract providing OpenAI models to Cursor, with a proposed shutoff on 12 November, and that it will not provide future models to Cursor. OpenAI said it cannot be confident SpaceX will follow its terms of service. We file this because a supplier ending a deal after a big purchase shows how fragile such ties can be. How we read it: OpenAI has set a proposed end date and says it will not supply later models. What would change this: a deal to keep OpenAI, or other suppliers leaving. Why it matters to you: the AI helper inside a coding tool can change when companies fall out.

What this doesn't prove

The 12 November date is proposed, not final. SpaceX and Cursor have not said they accept OpenAI's reasons.
