OpenAI will cut off Cursor's bundled model access on November 12

OpenAI announced it has notified SpaceX that it intends to wind down the contract providing OpenAI models to Cursor, with a proposed shutoff date of 2026-11-12 — the maximum notice available under the agreement. The reason given: after SpaceX's $60B acquisition of Anysphere closed, OpenAI says it cannot be confident SpaceX will use its technology within the terms of service, citing prior experience with Musk companies (Twitter's ToS breach; Musk admitting under oath that xAI violated OpenAI's ToS). The custom agreement includes a limited change-of-control cancellation window; OpenAI says it will hold the cancellation to the latest possible date while declining to provide future models to Cursor — explicitly naming accountability concerns around the upcoming model Astra. Developers can keep using OpenAI models inside Cursor via their own API key (bring-your-own-key) or the Codex IDE extension.

This is the first major change-of-control fallout of the SpaceX-Cursor acquisition (ev-20260814-06), and it lands on every team using OpenAI models inside Cursor: migrate before 11/12 — BYOK preserves access but changes billing and support posture, and future OpenAI models (Astra) will not ship to Cursor at all. The broader lesson generalizes: model access resold through an intermediary is now exposed to change-of-control clauses, so map which of your tools depend on which vendor contracts before the next acquisition does it for you.
