OpenAI to End Partnership with Cursor Following SpaceX Acquisition

OpenAI has decided to end its model-supply agreement with Cursor, a coding platform recently acquired by SpaceX. The termination is set to take effect on November 12, 2026, following nearly four years of collaboration.

The decision arises from OpenAI's concerns that SpaceX may not adhere to its terms of service, referencing past violations by companies associated with Elon Musk, including xAI and Twitter. OpenAI emphasized that partnerships with large organizations necessitate customized agreements to enforce compliance and ensure safe deployment of its models.

Cursor's acquisition by SpaceX, valued at $60 billion, triggered a change-of-control clause in the contract, allowing OpenAI to exit the agreement. While OpenAI has not accused Cursor of wrongdoing, it has expressed a lack of trust in SpaceX's ability to comply with its guidelines.

Michael Truell, a co-founder of Cursor, indicated that the impact of this decision would be minimal, affecting approximately 5% of user traffic. He noted that discussions with OpenAI remain open, despite the challenges posed by the termination.

As developers prepare for the upcoming changes, Cursor is already exploring alternative AI model suppliers, including SpaceXAI's Grok models and Anthropic's Claude.
