Bugbot Effort Levels

Teams admins and Individual plan users can now customize the effort level Bugbot uses for its PR reviews, with three different configurations:

  • **Default:** Bugbot continues to use the same effort level as it does today. Optimized for efficiency and speed.
  • **High:** Bugbot spends more time reasoning. Reviews are more expensive and take longer, but Bugbot may find more bugs.
  • **Custom:** Describe in natural language when Bugbot should use default or high effort. Cursor will dynamically set effort levels based on your instructions.

Customers must be on usage-based billing for Bugbot to customize effort levels. Learn more in our docs and go to your Bugbot dashboard to get started.

Bugbot improvements

  • With default effort, Bugbot finds 0.7 bugs per run, on average. Over 79% of these bugs are resolved by users at merge time.
  • With high effort, Bugbot finds 0.95 bugs per run, on average.
