Cursor Co-founder Responds to 'OpenAI Breakup': Working to Resolve, OpenAI Model Accounts for About 5% of Cursor User Traffic

Insightful Beating AI News, Cursor's Co-Founder and CEO Michael Truell wrote that OpenAI has issued a notice planning to block Cursor users' access to the OpenAI model in 3 months. Truell stated that currently the OpenAI model accounts for about 5% of Cursor's user traffic, and Cursor is in communication with the OpenAI team to address this issue.

Truell noted that Cursor was one of the earliest users of OpenAI, and the two have been collaborating for many years. Cursor has always trusted OpenAI to provide its platform as a "neutral infrastructure" service. At this juncture of changing the partnership, Cursor is facing intensified competition in the AI programming tool market and the dual pressure of model suppliers building their own applications.

Previously, two weeks after SpaceX completed its $60 billion acquisition of Cursor, OpenAI announced the end of the nearly four-year collaboration. Future new models will no longer be integrated into Cursor, and the direct supply of existing models is scheduled to stop on November 12, 2026. The contract between the two parties allows OpenAI to terminate the agreement with Cursor after the acquisition. OpenAI almost directly targeted Musk this time. It stated that Musk, after acquiring Twitter, violated the agreement with OpenAI. This year, Musk also admitted in court that xAI had improperly used the OpenAI model.
