OpenAI Pulls Cursor Models After SpaceX Deal, Citing Musk Contract Fears

OpenAI Pulls Cursor Models After SpaceX Deal, Citing Musk Contract Fears
OpenAI casts the split as a necessary safety and compliance measure after Cursor joined SpaceX, while Musk’s public response points toward a future in which Cursor leans more heavily on rival Anthropic’s models.

The rupture began after SpaceX acquired Cursor, the AI coding startup that had worked with OpenAI for nearly four years. OpenAI said it notified SpaceX that it intended to wind down the agreement supplying its models to Cursor, proposing a shutoff date of November 12, 2026 — the latest date allowed under the contract’s change-of-control provision.

OpenAI said the decision was “incredibly tough” because it wants developers to have broad model access. But it said it could not be confident SpaceX would use the technology within its terms, pointing to what it described as prior contract breaches by Musk companies. The company cited Twitter’s conduct after Musk bought it, and said Musk had acknowledged under oath that xAI violated OpenAI’s terms of service.

The company also tied the move to heightened responsibility around its forthcoming Astra model. It said large partners such as SpaceX normally require bespoke contracts covering compliance and safety at scale, and pledged to help developers navigate the transition.

Other coverage distilled the dispute more bluntly: OpenAI is ending the Cursor arrangement because it says Musk’s companies violate contracts. That is OpenAI’s allegation, not an independently established finding in the material provided.

Musk did not directly answer those claims. Instead, he posted two rocket emojis while amplifying a message that said Cursor had been a trusted Anthropic partner since Sonnet 3.5 and that Anthropic would increase compute to support Claude models in Cursor. The response suggests an alternative path for the newly acquired startup as OpenAI’s access is phased out.
