We unfortunately have decided that we cannot continue providing access to our models through Cursor and are ending our partnership. It boils down to trust and we’ve asked that this takes effect on November 12 to give you some time to plan. Many have used the GPT models through Cursor and here are options we know should work in the future: - We will continue to allow using your own OpenAI API key and similarly will continue to provide access through our IDE extensions for Cursor. - We will keep working with the broadest range of tools and harnesses, some of which are OSS, but also many many closed-source ones. We are as committed as ever to continue supporting developers and the flourishing ecosystem of tools, harnesses and products. We will also continue to invest in our own open-source initiatives and believe in broad optionality for developers. You can read more about our decision in the blog: https://t.co/Oj76Bkc2KX
Context
OpenAI announced in late August 2026 that it was ending its partnership with Cursor following Cursor's acquisition by SpaceX. Under its proposal, Cursor's direct access to OpenAI's models would end on November 12. That was a planned wind-down date, not an already completed cutoff.
The accompanying developer update said users would still be allowed to connect with their own OpenAI API key or use the company's IDE extensions for Cursor. The change therefore concerned the direct partnership, while those alternative access methods remained part of the stated plan.
