OpenAI says it cannot be confident SpaceX will comply with its terms of service, citing past disputes involving Musk-owned companies like Twitter/X and xAI. OpenAI will withhold future model releases, including its upcoming Astra model, from Cursor during the transition. Cursor CEO Michael Truell said OpenAI models account for only about 5% of platform traffic, and Cursor still offers Claude, Gemini, and Grok models. Anthropic's Tom Brown said it will increase compute to support Claude in Cursor. This echoes a similar 2025 incident where Anthropic limited Windsurf's access to Claude models after OpenAI's planned (later collapsed) acquisition of Windsurf. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### When will Cursor lose direct access to OpenAI models? OpenAI plans to end Cursor's direct access to its models on November 12, 2026. OpenAI notified SpaceX of this decision on August 28, 2026, following SpaceX's acquisition of Cursor's parent company Anysphere. OpenAI will not provide Cursor with future model releases, including its upcoming Astra model, during the transition period leading up to the shutoff. _developers relying on OpenAI models in Cursor can track how this transition unfolds on daily.dev._ ### Why did OpenAI cut off Cursor's access to its AI models? OpenAI says it cannot be confident that SpaceX, which acquired Cursor's parent company Anysphere, will use its technology within OpenAI's terms of service. OpenAI cited past disputes, including Twitter (now part of SpaceX) breaking its OpenAI contract terms and Elon Musk admitting under oath that xAI, also part of SpaceX, violated OpenAI's terms of service. _anyone weighing AI vendor risk in their coding stack can follow this Cursor-OpenAI dispute on daily.dev._ ### How dependent is Cursor on OpenAI's models compared to other providers? OpenAI models account for only about 5% of Cursor's user traffic, according to Cursor CEO Michael Truell. Cursor also offers Claude Opus and Sonnet, Gemini 3.1 Pro and 3.7 Flash, and SpaceXAI's Grok models, and Anthropic has said it will increase compute to support Claude in Cursor, suggesting the OpenAI cutoff is disruptive but not existential for the platform. _developers choosing between model providers in their coding tools can weigh options like this on daily.dev._ --- Tags: [#openai](https://daily.dev/tags/openai), [#ai-coding](https://daily.dev/tags/ai-coding), [#spacex](https://daily.dev/tags/spacex) [View this post on daily.dev](https://daily.dev/posts/openai-cuts-off-cursor-s-model-access-after-spacex-acquisition-ojiknzvtc) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"OpenAI Cuts Off Cursor’s Model Access After SpaceX Acquisition","url":"https://daily.dev/posts/openai-cuts-off-cursor-s-model-access-after-spacex-acquisition-ojiknzvtc","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/openai-cuts-off-cursor-s-model-access-after-spacex-acquisition-ojiknzvtc"},"datePublished":"2026-08-31T19:20:21.993Z","dateModified":"2026-09-01T14:35:34.298Z","description":"OpenAI has notified SpaceX that it will end Cursor's direct access to its AI models on Nov. 12, 2026, following SpaceX's acquisition of Cursor's parent company...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/9e300493047a02064abc17c6b085128a?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/9e300493047a02064abc17c6b085128a?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"DevOps.com","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"DevOps.com","logo":"https://media.daily.dev/image/upload/t_logo,f_auto/v1/logos/db8f2265cff0416c878c6e7e92bb8715","url":"https://daily.dev/sources/devops"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/openai-cuts-off-cursor-s-model-access-after-spacex-acquisition-ojiknzvtc","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"openai,ai-coding,spacex","timeRequired":"PT6M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"DevOps.com","item":"https://daily.dev/sources/devops"},{"@type":"ListItem","position":3,"name":"OpenAI Cuts Off Cursor’s Model Access After SpaceX Acquisition"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/openai-cuts-off-cursor-s-model-access-after-spacex-acquisition-ojiknzvtc#faq","mainEntity":[{"@type":"Question","name":"When will Cursor lose direct access to OpenAI models?","acceptedAnswer":{"@type":"Answer","text":"OpenAI plans to end Cursor's direct access to its models on November 12, 2026.
