# Cursor Bugbot: configurable effort levels for PR reviews

> Teams admins and Individual plan users on usage-based billing can now choose between Default, High, and Custom effort levels for Bugbot PR reviews. High effort spends more time reasoning and finds more bugs (0.95 vs 0.7 per run) but costs more. Custom mode lets you describe in natural language when each level should apply.
