OpenAI has notified SpaceX that it intends to wind down the contract providing its models to Cursor after the coding platform’s acquisition by SpaceX. In a post on X, OpenAI proposed ending Cursor’s direct access to its models on November 12, 2026.
OpenAI claims the date provides “the maximum notice allowed” under the contract, allowing developers to retain access through Cursor for as long as possible. The company also acknowledges that developers who rely on its models in Cursor will be most affected and states that it is prepared to provide additional support during the transition.
The company attributes the decision to uncertainty over whether SpaceX will use its technology within OpenAI’s terms of service. OpenAI cites what it describes as previous contract violations involving Elon Musk’s companies, though the post does not provide further details. Reposted material associated with the discussion also referenced an AI Overview claiming that Musk admitted under oath that xAI partly used OpenAI technology to train models including Grok.
The announcement prompted criticism from several users, including claims that OpenAI was contradicting its previous position on allowing models to be used through different development tools. Other responses treated the change as relatively minor, with one Cursor user claiming to have used OpenAI models only occasionally and relying instead on other models.
Replit CEO Amjad Masad offered businesses access to OpenAI models through Replit and invited companies seeking a “multi-model alternative to Cursor” to discuss transition support. The offer adds a commercial response to a decision that could push affected developers and organizations toward other coding platforms.
OpenAI’s proposal concerns Cursor’s direct access to its models; the post does not state that Cursor itself will shut down or that access to other model providers will end.
