Private

Cursor sends every request from its own servers, which can't reach a proxy on your machine, so private inference doesn't work in Cursor.

Your key works for Chat and Agent; Tab always uses Cursor's own models. With the override on, requests for Cursor's built-in OpenAI models go to Pollio too.
