What does the auto mode of Cursor mean?

I’ve used both Auto mode and Composer 2.5, but both seem to consume my plan quota.

Auto chooses the “best model for the task”, optimizing for speed and intelligence (but mostly for price, if we’re being honest).
As such, this is usually a worse model than the ones you can use via API…
Anyways, Cursor now has 2 quotas, API usage and auto usage. Composer models are included in auto.

Hey, thanks for the request. This is expected behavior, not a bug.

Auto mode is where Cursor picks the best model for the task, balancing speed and quality. On individual plans, there are two separate included usage pools:

  • Auto + Composer: both Auto and Composer 2.5 use this pool, so they share the same quota.
  • API: a separate pool for third-party models like Claude, GPT, Gemini, etc.

So what you’re seeing is by design. Auto and Composer 2.5 both draw from the same Auto + Composer pool. You can check the usage breakdown anytime at cursor.com/dashboard under Usage.

Let me know if you’ve got any other questions.

Hi Dean!

  1. If my enterprise only allows Models A,B,C out of A,B,C,D, can D get used via Auto mode?

  2. If on the client side I only allow A,B out of A,B,C can C be used via Auto Mode?

  3. Is there any documentation on this?

Thanks!

@Mark4, here are the answers point by point:

  1. No. Team model access controls are enforced server-side on every Auto routing path, so Auto only chooses from models your team is allowed to use. If the router would pick a blocked model, it switches to an allowed one instead.

  2. Yes. The checkboxes in Cursor Settings > Models are a personal preference that only controls which models show up in your model picker. They’re stored locally, Auto routing doesn’t use them, so Auto can still pick C. Only admin-level controls limit what Auto can choose.

  3. Yes:

Also, these same questions are already covered in a separate thread: How does auto mode work?. Let’s keep the discussion there to avoid duplicates. Ping me if you’ve got more questions.
