Michael Guo(@Michaelzsguo):This almost suggests OpenAI’s next frontier model, Astra, will arrive before November 12. If Astra is one of the reasons OpenAI is breaking with Cursor, and November 12 is the latest date OpenAI is contractually required to keep providing models to Cursor, then the logic is pretty clear: OpenAI wants to keep honoring the existing contract for as long as possible, but not long enough for Cursor to get access to Astra.

We’re ending our partnership with Cursor following its acquisition by SpaceX. Under our proposal, Cursor’s direct access to our models would end on November 12. We know that the people most affected by this decision are the developers who rely on OpenAI models in Cursor. We care about their experience in this transition and we’re ready to go above and beyond to support them.
