Cursor customers will lose access to OpenAI coding models in November

OpenAI will stop AI coding platform Cursor from accessing its models from November 12, following the acquisition of Cursor parent Anysphere by Elon Musk‘s SpaceX.

“Today, we notified SpaceX that we intend to wind down our contract providing OpenAI models to Cursor, with a proposed shutoff date of November 12, 2026,” the company wrote in a blog post.

That shutoff, the company added, was based on its concerns that SpaceX will not use its technology in accordance with its terms of service, citing what it described as a history of Musk’s companies violating contracts: “After Musk acquired Twitter, now part of SpaceX, the company broke⁠ the terms of our contract (alongside many others). Under oath earlier this year, Musk admitted⁠ that xAI, now also part of SpaceX, had violated OpenAI’s terms of service (terms which are similar to xAI’s own),” the company wrote.
