OpenAI Terminates Model Access for Cursor Following SpaceX Acquisition

OpenAI has announced it will cut off access to its models from Cursor on November 12, following SpaceX's $60 billion acquisition of Anysphere, the parent company of Cursor. OpenAI cited concerns over potential misuse by Elon Musk’s companies based on past contract violations involving X and xAI. Despite this move, only about 5% of Cursor's user traffic relies on OpenAI models, limiting immediate disruption to most users. Cursor CEO Michael Truell stated that the two firms are discussing the decision, while Musk criticized OpenAI as 'utterly untrustworthy' in a public post. Anthropic has pledged increased support for its Claude models within Cursor, offering an alternative partnership amid reduced access from OpenAI. The transition period of nearly three months aims to minimize disruption. The move could push Cursor toward deeper partnerships with other model providers and leverage SpaceX’s AI infrastructure. However, the decision may also create reputational risks for SpaceX due to concerns over contract adherence.
