OpenAI will end its model supply agreement with Cursor by November 12, following SpaceX's $60 billion acquisition of the AI coding platform. The decision cites

OpenAI announced on August 28 that it will terminate its agreement to provide AI models to Cursor, the AI coding platform recently acquired by Elon Musk's SpaceX, with access scheduled to end on November 12 [1, 2]. The decision follows SpaceX's acquisition of Cursor's parent company, Anysphere, in a transaction valued at $60 billion, and stems from OpenAI's stated concerns about SpaceX's compliance with its terms of service [1, 2].

## Contract Termination and Compliance Concerns
OpenAI cited a change in Cursor's ownership and previous contract violations by Musk's companies as reasons for its decision [1, 2]. The company stated it could not be confident that SpaceX would use its technology within OpenAI's terms of service [1]. OpenAI noted that after Musk acquired Twitter, which is now part of SpaceX, the company breached its contract with OpenAI [2]. Additionally, OpenAI stated that Musk acknowledged under oath earlier this year that xAI, also now part of SpaceX, had violated OpenAI's terms of service [1, 2].

The agreement between OpenAI and Cursor includes a limited cancellation window following a change in control [1, 2]. OpenAI said it is providing the maximum notice permitted under the contract, allowing developers to retain access to its models through Cursor until the November 12 cutoff [1, 2]. The termination means OpenAI will not provide upcoming models, including its planned Astra model, to Cursor [1, 2]. OpenAI has worked with Cursor for nearly four years and acknowledged that developers using its models through the platform would be most directly affected, stating it is prepared to support users during the transition [1, 2].

## SpaceX Acquisition and Cursor's Future
SpaceX completed its acquisition of Anysphere, Cursor's parent company, on August 14 [1, 2]. The transaction was structured as an all-stock merger, with Anysphere shareholders receiving 389.29 million shares of SpaceX Class A common stock [1]. Based on the agreed share consideration, the acquisition assigned Cursor an implied equity value of $60 billion [1, 2]. Cursor confirmed the acquisition on August 14, stating it had officially become a wholly owned subsidiary of SpaceX [1, 2].

Cursor announced that the integration with SpaceX would provide access to SpaceX's computing capacity, including what it described as the largest fleet of GPUs in the world [1, 2]. This access is intended to allow Cursor to develop and operate more capable AI models at lower operating costs [1, 2]. Cursor cited Grok 4.6 as an early product of this relationship, which it said was released the same week as the acquisition [1, 2]. The company's objective remains to provide developers with more capable AI tools at lower operating costs [1].

OpenAI's upcoming Astra model, which will not be supplied to Cursor, has been internally evaluated for significant advancements in agentic coding and cybersecurity [2]. OpenAI's August 7 disclosure indicated that preliminary evaluations of Astra suggested it could not rule out "Critical" cyber capabilities under its Preparedness Framework, a higher threshold than previous models like GPT-5.6-Sol [2].

## What to watch
*   **Developer Transition:** Monitor how developers currently using OpenAI models through Cursor adapt to the November 12 cutoff and whether they migrate to other platforms or to Cursor's new, SpaceX-backed AI models [1].
*   **Cursor's Model Development:** Observe the development and release of new AI models from Cursor, particularly how they leverage SpaceX's computing resources and compare to OpenAI's offerings [1, 2].
*   **Competitive Landscape:** Watch for any further shifts in partnerships or acquisitions within the AI coding platform sector, especially as major players like OpenAI and SpaceX-backed Cursor redefine their strategies [1].

The termination of this long-standing agreement highlights the increasing commercial and strategic tensions between major AI developers and their partners, particularly in the context of ownership changes and intellectual property concerns.
