OpenAI to end partnership with SpaceX's Cursor, citing lack of confidence in terms-of-service compliance; proposed shutoff date November 12, 2026

OpenAI announced plans to end its partnership with SpaceX's Cursor, citing a lack of confidence in compliance with its terms of service. The proposed shutoff date is November 12, 2026. OpenAI expressed concerns that SpaceX may not adhere to its technology usage guidelines, referencing previous contract violations by Elon Musk's companies.¹²³⁴⁵

"This decision was incredibly tough, as we care deeply about our models being broadly available for developers," OpenAI stated. The company emphasized that it typically relies on custom contracts to ensure compliance and safety when working with large partners like SpaceX.

OpenAI's decision comes after a history of contract violations, including an incident where Musk, under oath, acknowledged that xAI, now part of SpaceX, had violated OpenAI's terms of service. OpenAI noted, "Given all of this, we’ve decided to hold the contract cancellation to the latest date we can while not providing future models to Cursor."

The company has worked with Cursor for nearly four years and expressed respect for their team and product, acknowledging the impact on developers who rely on OpenAI models through Cursor. OpenAI is committed to supporting developers during this transition, stating, "We care about their experience in this transition and we’re ready to go above and beyond to support them."
