Today is the day OpenAI picked to pull GPT out of Cursor: what actually breaks, and 3 ways to keep using it
After SpaceX bought Cursor's parent company in August, OpenAI said it would wind down its contract supplying models to Cursor and proposed November 12, 2026 as the shutoff date, and that it would not give Cursor future models. OpenAI's help article says the final termination date still has to be confirmed by both companies and that Cursor may end access sooner. Cursor CEO Michael Truell said in August that OpenAI models served about 5% of Cursor traffic. Claude, Gemini and Grok models aren't affected.
Why it matters
If you pick GPT models in Cursor, or rely on Auto mode, the model doing your work may change without much warning, and prompts or rules tuned for GPT can behave differently on another model.
Who it's for
Cursor users and teams who choose GPT models in the model picker or run Cursor on Auto.
What it means for you
- Open Cursor's model picker and note which of your chats, rules or team defaults use a GPT model.
- If you want to keep GPT locally, add your own OpenAI API key in Cursor's model settings, or install the Codex IDE extension.
- Re-run a couple of your usual tasks on the model you'll switch to (Claude, Gemini or Grok) and adjust any rules that assumed GPT's behavior.
Applies to: Applies to OpenAI models supplied through Cursor. OpenAI lists three ways to keep using its models inside Cursor: your own OpenAI API key (local Chat and Agent only, billed at API prices), the Codex IDE extension (with a ChatGPT plan or API key), or an OpenAI-compatible gateway such as Amazon Bedrock or Azure. Bring-your-own-key doesn't cover Cursor Tab, Auto, Cloud or Background Agents, Automations, the CLI, or the API and SDK. Checked against OpenAI's help article and announcement on November 12, 2026; the confirmed end date wasn't public yet.
