OpenAI said on August 29, 2026 that it will wind down Cursor's access to OpenAI models, with a hard cutoff on November 12, 2026. The decision follows SpaceX's acquisition of Cursor, and it changes which models millions of developers can reach inside one of the most popular AI coding editors.

What Happened

SpaceX closed its acquisition of Cursor on August 14, 2026, and OpenAI announced the wind-down 15 days later. OpenAI said it could not be confident that SpaceX would use its technology within its terms of service, citing past contract disputes with Elon Musk's companies. OpenAI is giving the maximum notice its contract allows so developers keep access for as long as possible.

OpenAI also confirmed it will withhold its next model, Astra, from Cursor entirely. The move echoes Anthropic's earlier decision to pull Claude from Windsurf while that editor was an acquisition target, a pattern now repeating across AI coding tools.

What to Do If You Build in Cursor

You do not lose GPT overnight, and you have four practical paths. Add your own OpenAI API key inside Cursor and pay per token instead of routing through Cursor's plan. Keep the OpenAI Cursor IDE extension, which maintains a direct line to GPT models. Switch your default to Claude or Gemini in Cursor, both already built in and strong at coding. Or move to an open alternative such as Continue or Claude Code, which cover much of the same agentic workflow.

Why It Matters for Creators

Cursor is a daily driver for developers, indie builders, and anyone shipping apps and sites with AI. A model cutoff is not just corporate drama: it decides which assistant writes your code and how much you pay for it. If your team standardized on GPT inside Cursor, November 12 is a deadline to plan around, not a surprise to absorb.

Key Details

Cutoff date: November 12, 2026, per OpenAI's stated timeline.

Acquisition: SpaceX closed its Cursor deal on August 14, 2026.

Withheld: OpenAI's next-generation Astra model will not reach Cursor.

Still available: GPT through your own API key or the OpenAI IDE extension; Claude and Gemini through Cursor.

What to Do Next

If you administer a Cursor Team or Enterprise plan, change the org default model now and tell your team why, so no one discovers the shift mid-sprint. Solo builders should test Claude and Gemini on a real task this week and note where GPT still wins, then decide before the November deadline.
