Single Cursor Prompt Burns Entire Usage Quota
tetsuoai · x · 2026-07-13
A user reported abnormal behavior with Cursor's Fable model from a single prompt:
- It generated only 145 lines of code, yet exhausted their entire quota for about 5 hours
- Consumed 38% of the monthly limit
- Triggered 157.1 million cache reads
- Still failed to complete the task
The author exclaims they cannot understand how this is possible, pointing to billing/caching/invocation anomalies in coding assistants during actual use.
