Overview
- OpenAI disclosed Friday that it plans to end model access for Cursor and proposed November 12, 2026 as the latest shutdown date.
- The company said it will not supply future models to Cursor and specifically named its upcoming Astra model as excluded.
- Cursor joined SpaceX in mid‑August in an all‑stock deal reported at about $60 billion, a purchase that gives the team access to SpaceXAI’s Colossus compute capacity.
- Cursor and SpaceX said they are talking with OpenAI while preparing to move customers to alternatives such as Anthropic, Cursor’s Composer model, or SpaceX compute, a transition that could disrupt developer workflows built around OpenAI models.
- OpenAI cited change‑of‑control contract rights and past breaches by Musk‑owned firms as its rationale, a move that amplifies the personal and legal rivalry between Elon Musk and OpenAI leadership and may reshape who can access frontier models.
