OpenAI plans to pull its models from Cursor on 12th Nov, and your own API key only keeps them in the desktop app

OpenAI told SpaceX in late August, after SpaceX bought Cursor, that it intends to end the contract that supplies OpenAI models to Cursor, and proposed 12th Nov'26 as the cut-off. OpenAI's help page, last updated in late October, says the final date is still to be agreed between the two companies and that Cursor may end access sooner. OpenAI gives three ways to keep using its models inside Cursor: your own OpenAI API key, billed separately at API prices; the Codex extension, which runs as its own agent inside the editor; or a gateway such as Amazon Bedrock or Azure. All three cover only local Chat and Agent in the desktop app. Cursor's Tab completion, Auto model routing, Cloud and Background Agents, Automations, the Cursor CLI and its API and SDK cannot use your key or gateway credentials, because Cursor supplies the models for those itself. OpenAI's stated reason is that it is not confident SpaceX will use its technology within its terms.
