Bugbot gets 3x faster and about 22% cheaper per run, now on Composer 2.5

What changed

An average Bugbot review now takes about 90 seconds instead of about five minutes, each run costs roughly 22% less, and Cursor says bugs found per review rose from 0.56 to 0.62. Composer 2.5 is now the model behind Bugbot, and Bugbot respects model block lists. New /review, /review-bugbot and /review-security commands run Bugbot and Security Review locally before you push; if you then open a PR with the same diff, Bugbot skips the repeat review. /review needs Cursor 3.7 or later.

Who it affects

Teams using Bugbot for PR review, and developers who want pre-push checks.

What to do

Update to Cursor 3.7 or later and run /review before pushing so you don’t pay for a second review on the same diff.
