Does this stop you from using Cursor

No - Cursor works, but with this issue

Hey, thanks for the report and for the attached CSV with usage.

First off, the key point is that on-demand is turned off on your account, so nothing beyond your subscription was charged. All requests were counted as included usage.

What you’re seeing is how the two included pools work together. Your subscription includes two pools of included usage (Cursor Models and Other Models). When one pool is fully used, Cursor doesn’t stop. It keeps serving requests, and the usage can be counted against the other included pool. That’s why the Other Models bar reached 100% even though you barely used Sonnet or Opus. It’s not real third-party model calls, it’s continued included usage. Everything is within the subscription, and there are no extra charges.

The exact breakdown by models and pools can vary depending on your plan and current setup. You can always see the up to date breakdown in Dashboard > Usage. Pricing details: Models & Pricing | Cursor Docs

There isn’t a setting right now to stop at the limit of one pool and not switch to the other. I’ll pass this along as feedback.

Usage resets at the start of your next cycle, on 20 September at 16:28 UTC (21:58 Colombo time). Until then, Auto will keep working.
