OpenAI said Friday it plans to stop providing its artificial intelligence models to Cursor, the coding-tool company recently acquired by Elon Musk’s SpaceX, escalating a long-running feud between Musk and OpenAI CEO Sam Altman.
The ChatGPT maker said it proposed ending Cursor’s access to its models on Nov. 12, citing concerns about whether SpaceX would comply with its terms of service following the change in ownership.
“We are making this choice because we cannot be confident that SpaceX will use our technology within our terms of service,” OpenAI said.
The company said its agreement with Cursor allowed it a limited period to terminate the contract after a “change of control.” OpenAI said large partnerships typically require customised agreements to ensure compliance and safety at scale.
Cursor, developed by Anysphere, is an artificial intelligence-powered coding tool that uses models from several companies. SpaceX completed its acquisition of Anysphere earlier this month, according to Reuters.
The move marks the latest escalation in the bitter dispute between Musk, an OpenAI co-founder, and Altman. Musk has repeatedly criticised OpenAI’s direction and sued the company over its transformation from a nonprofit organisation into a for-profit business.
Cursor said discussions with OpenAI were continuing, while rival AI company Anthropic said it planned to expand support for its Claude models on the platform.
