OpenAI Ends Cursor Partnership Amidst Musk’s Criticism
By Business Desk
OpenAI ends its 4-year partnership with Elon Musk’s Cursor due to compliance concerns. Musk criticizes the move, escalating tensions with Sam Altman.
OpenAI has officially terminated its nearly four-year partnership with Cursor, a coding tool recently acquired by Elon Musk’s SpaceX. This decision further intensifies the ongoing dispute between Musk and OpenAI CEO Sam Altman.
Musk reacted sharply on X, stating he “couldn’t care less” about the move. He publicly accused Altman and OpenAI President Greg Brockman of being “untrustworthy assholes who stole an open source nonprofit,” referencing his separate lawsuit against the company and Altman for allegedly deviating from its original mission.
OpenAI Cites Compliance Concerns
OpenAI cited concerns about ensuring compliance with its terms and the safe deployment of its models as the primary reason for ending the collaboration. The company specifically referenced Musk’s acquisition of Twitter, now part of SpaceX, and his prior admission that xAI had breached comparable terms.
- OpenAI notified SpaceX of its intent to wind down the contract by November 12, 2026, providing maximum notice.
- The company stated it could not be confident in SpaceX’s future adherence to its terms, citing past issues with Musk’s companies.
- A custom agreement with Cursor allowed for a limited cancellation window following a change of control, emphasizing the need for increased accountability ahead of the upcoming Astra model launch.
Cursor’s Historical Tie and Usage
Michael Truell, Cursor’s co-founder and a SpaceX executive, responded on X, confirming that SpaceX is actively engaging in discussions with OpenAI to find a resolution. Truell highlighted Cursor’s long-standing relationship as one of OpenAI’s earliest users.
- OpenAI’s models currently constitute approximately 5% of Cursor’s user traffic.
- Cursor had previously relied on OpenAI as neutral infrastructure for its operations.
OpenAI, while expressing respect for Cursor’s team and product, reiterated its primary concern for developers utilizing its models through Cursor. The company committed to supporting these developers during the transition period.
