Bugbot is now over 3x faster, 22% cheaper, and finds 10% more bugs

June 10, 2026

A new /review command for pre-push Bugbot and Security reviews, featuring intelligent synchronization with GitHub and GitLab pull requests to prevent duplicate reviews. Additional user control includes Bugbot configuration to focus only on new changes since the last review. Significant performance enhancements to Bugbot's core include over 3x faster review times (down to ~90 seconds), a 22% reduction in cost per run, and a 10% increase in bugs found per review. These updates offer users a more efficient, cost-effective, and targeted code review experience.

Added

You can now configure Bugbot to only review what's new since the last review, keeping feedback focused on your latest updates.

Changed

The average review time for Bugbot is now ~90 seconds, down from ~5 minutes. Bugbot also finds 10% more bugs per review on average — 0.62, up from 0.56 — and costs ~22% less per run.

These performance gains are made possible by progress we've made training Composer 2.5, which now powers Bugbot. Bugbot respects model block lists, and speed and performance can vary depending on your configuration.
You can now run Bugbot and Security Review with `/review` before pushing code. `/review` prompts you to choose which agents to run, or use `/review-bugbot` and `/review-security` directly.
`/review` also syncs with Bugbot on GitHub and GitLab. If you run `/review` and then open a PR with the same diff, Bugbot recognizes it, skips the review, and leaves a comment noting it has already reviewed that diff.
Available in Cursor 3.7+ and on cursor.com/agents, with support in CLI coming soon.
