KARACHI – OpenAI plans to end Cursor’s direct access to its AI models on November 12, 2026, giving developers more than two months to prepare for the change.
The decision comes shortly after SpaceX completed its acquisition of the AI coding startup in an all-stock deal valued at $60 billion.
SpaceX completed the acquisition on August 14. The companies had begun working together earlier this year to train an AI model, after which SpaceX exercised an option to acquire Cursor.
OpenAI cites trust concerns
OpenAI said the decision was linked to concerns about whether SpaceX would use its technology in accordance with the company’s terms of service.
The company also referred to previous contract violations involving businesses associated with Elon Musk. However, OpenAI did not provide specific details about how it believed SpaceX could misuse its models through Cursor.
The company framed the decision as a consequence of Cursor’s change in ownership rather than an issue with the coding platform itself.
OpenAI said developers who currently use its models through Cursor would be among those most affected. It also said it would support them during the transition.

Cursor relied on several AI models
Before the acquisition, Cursor used models from several major AI companies, including OpenAI, Anthropic and Google.
The platform allows developers to select different models through its chat and agent interfaces. OpenAI’s departure will therefore remove one major supplier but will not prevent users from accessing other AI models through Cursor.
Cursor has increasingly positioned itself as a multi-model coding platform rather than relying on a single AI provider.
The company reached a valuation of $29.3 billion in late 2025 and was generating more than $1 billion in annualised revenue before SpaceX agreed to acquire it for $60bn.
Fortune reported in March that Cursor was being used by 67 per cent of Fortune 500 companies and was generating about 150 million lines of enterprise code each day.
Cursor chief executive Michael Truell has previously said the company aims to give developers access to the strongest AI models available rather than depend on one provider.

Acquisition puts strategy to the test
OpenAI’s planned departure will test Cursor’s multi-model strategy as the platform adjusts to losing one of its biggest model providers.
Cursor can continue using models from Anthropic, Google and other providers. However, developers who prefer OpenAI models will need to consider other options after November 12.
The situation also reflects a broader shift in the AI industry, where model providers are becoming more cautious about how third-party products access and distribute their technology.
AI companies tighten third-party access
Anthropic has previously taken action against unauthorised access to Claude through third-party coding tools. Some services subsequently moved towards approved API access instead of indirectly using consumer subscriptions.
OpenAI has taken a different approach in some cases. The company has worked with coding platform OpenCode to let users access its models through ChatGPT or Codex subscriptions.
The differing approaches underline the growing importance of control over AI model access as coding platforms increasingly integrate models from multiple providers.
For Cursor users, the immediate issue is what will happen after November 12.
OpenAI has not provided detailed information about the support it plans to offer affected developers. It remains unclear whether the company will provide migration assistance, temporary exceptions or other transition measures.
For now, November 12, 2026, remains the proposed deadline for OpenAI’s direct model access through Cursor.
