Overview
- OpenAI told SpaceX on Friday that it intends to wind down the contract supplying OpenAI models to Cursor and proposed November 12, 2026 as the latest permissible cutoff under a change‑of‑control clause.
- OpenAI said the decision rests on past contract breaches by companies controlled by Elon Musk, including claims about X and sworn testimony about xAI, and it invoked the agreement’s limited cancellation window to protect its terms of service.
- OpenAI will stop providing future models to Cursor, explicitly including its forthcoming Astra model, which forces Cursor users who rely on OpenAI models to migrate or use personal API keys before the shutdown.
- Cursor and SpaceX say they are in talks with OpenAI and point out OpenAI models account for roughly 5% of Cursor traffic, while competitors such as Anthropic have pledged increased Claude support to reduce disruption.
- The move deepens the public and legal feud between Elon Musk and OpenAI and highlights how change‑of‑control clauses and supplier trust can reshape access to AI models and developer tooling.
