OpenAI follows SpaceX’s acquisition of Cursor developer Anysphere Cursor model will end its access on November 12, 2026. The company decided to terminate the agreement, which has been ongoing for approximately four years. On August 28, 2026 He reported it to SpaceX. In contrast, Cursor management ensures that OpenAI models only account for total usage on the platform. 5 percent announced that he created it. Therefore, the change does not concern the entire Cursor service, but directly the workflows that use OpenAI models.
OpenAI does not attribute its decision to Cursor’s performance, product quality, or the work of the Anysphere team. Instead, the company says it lacks sufficient confidence that SpaceX will use OpenAI technology in accordance with its current contract terms. Also with OpenAI Elon Musk Long-standing disagreements between the two are in the background of the decision. Musk was among the founders of OpenAI, but later left the company and made various criticisms of the management over the years.
However, the exclusive agreement OpenAI signed with Cursor allows the agreement to be terminated if company control changes. OpenAI states that it exercises its right to terminate the contract within the limited period granted to it in this article. The company also restricts access to existing models by choosing the longest notice period allowed by the contract. until November 12 keeps it open. In contrast, OpenAI will release future He said he would not supply the Astra model to Cursor. also states it clearly.
SpaceX developed Cursor Acquired Anysphere on August 14, 2026 and the companies thus furthered the cooperation that had begun earlier. In its official statement, Cursor described this acquisition as the continuation of the partnership that started with SpaceXAI in April. The company stated that SpaceX’s large GPU resources will help it develop more powerful and lower-cost models. Reuters reported that the parties paid approximately approx. 60 billion dollars He said he had reached an agreement.
Cursor users will have access to OpenAI models until November 12
Cursor co-founder Michael Truellannounced that OpenAI models account for approximately 5 percent of total Cursor traffic. Despite this, the company continues its negotiations with OpenAI and November 12, 2026 Maintains current access until. On the other hand, Cursor does not only work with OpenAI models, the platform also supports Anthropic, Google and SpaceXAI models. Cursor’s official documentation lists the GPT family as well as Claude, Gemini, Grok and the company’s own models among its model options.
Cursor’s current documentation describes its product as a coding agent and offers tasks such as understanding the code base, debugging, and code review. In addition, different subscription options on the platform manage third-party models and Cursor’s own models through separate usage pools. Therefore, the end of access to OpenAI does not mean that Cursor’s code completion or AI-powered development features will be completely shut down. On the other hand, developers who prefer direct OpenAI models will have to choose another model after November 12.
Meanwhile Anthropicannounced that it will increase the computational capacity allocated for Claude models in Cursor, following OpenAI’s decision. Cursor thus continues to use Claude, Gemini, Grok and its own models, while continuing to negotiate access on the OpenAI side. Additionally, Cursor has recently Grok 4.6 It started to offer SpaceXAI models such as within its own model options. The official Cursor documentation today lists SpaceXAI models among the supported options, along with other providers.
Elon Musk after OpenAI’s statement Sam Altman and President of OpenAI Greg Brockman He continued his criticism of him. In response, Michael Truell made a more conciliatory statement, stating that negotiations between the parties were continuing. OpenAI for now Access ends November 12, 2026 and excludes the future Astra model. There are no other changes to the schedule at this stage, as neither party has announced a new agreement on the current plan.
The most immediate change for Cursor users will be the end of current access to OpenAI models in November. However, on the platform Claude, Gemini, Grok and Cursor models will continue to be used, while existing OpenAI models will remain accessible until the announced date. While OpenAI uses the terms “model”, “API Platform” and “developers” for its developer products on its Turkish site, Cursor defines its product as a coding agent in its official documents. Negotiations between Cursor and OpenAI also November 12, 2026 will continue before the date.
