OpenAI plans to end Cursor's access to its models on November 12, 2026

After SpaceX's acquisition of Cursor, OpenAI announced it is winding down its contract supplying models to Cursor with a proposed November 12 cutoff. Cursor's CEO said OpenAI models serve about 5% of Cursor traffic. Cursor's model docs list no GPT-6 models. The Hacker News thread drew 852 points and 544 comments.

Who is affected:

Cursor users who rely on OpenAI models.

Action needed:

Move Cursor workflows off OpenAI models before November 12, 2026, or use Codex or another tool for them.
