OpenAI cuts off Cursor's AI models, deepening feud with Musk

OpenAI will terminate its partnership with Cursor on November 12, removing access to its AI coding models. The decision follows the acquisition of Cursor by Elon Musk's SpaceX in a deal valued at $60 billion. OpenAI claims the move is due to contract violations by Musk's companies. While Cursor's CEO states the loss represents only 5% of its traffic, the move escalates the ongoing conflict between OpenAI and Musk into the AI infrastructure sector.

    OpenAI will terminate its partnership with Cursor on November 12, removing access to its AI coding models. The decision follows the acquisition of Cursor by Elon Musk's SpaceX in a deal valued at $60 billion. OpenAI claims the move is due to contract violations by Musk's companies. While Cursor's CEO states the loss represents only 5% of its traffic, the move escalates the ongoing conflict between OpenAI and Musk into the AI infrastructure sector.

    Why it matters

    Elon Musk and OpenAI CEO Sam Altman have a long-standing public feud. The acquisition of Cursor by SpaceX creates a direct conflict of interest as Musk develops his own AI, Grok. This move forces Cursor users to either switch coding platforms or adopt different AI models.

    • OpenAI will end its partnership and model access for Cursor on November 12.
    • SpaceX acquired Cursor in a $60 billion deal.
    • OpenAI cited contract violations by Elon Musk's companies as the reason for ending the deal.

    Still unconfirmed
