Today, we notified Space X that we intend to wind down our contract providing Open AI models to Cursor, with a proposed shutoff date of November 12, 2026. To maximize the time that developers can retain access to our models through Cursor, we are giving the maximum notice provided by our contract. This decision was incredibly tough, as we care deeply about our models being broadly available for developers.

We are making this choice because we cannot be confident that Space X will use our technology within our terms of service, based on our experience with Elon Musk's companies violating contracts. After Musk acquired Twitter, now part of Space X, the company broke the terms of our contract. Under oath earlier this year, Musk admitted that x AI, now also part of Space X, had violated Open AI's terms of service.

Our custom agreement with Cursor gives us a limited time window to cancel it after a change of control. As AI capabilities advance, we also have a new level of accountability to ensure our upcoming model, Astra, is being used in accordance with our terms. We've worked with Cursor for nearly four years and have enormous respect for their team. We know that the people most affected by this decision are the developers who rely on Open AI models in Cursor, and we're ready to go above and beyond to support them.
