Feedback: It should be mentioned explicitly on Settings | Cursor - The AI-first Code Editor and/or the Docs or Pricing page that the 2000 completions on Hobby plan, unlike the model inference requests, does not renew monthly and does not work with external service API keys.
I think it’s a point of confusion to many users, as I found several posts that ask about the same thing.
