Bug Hunt Bench ranks frontier coding models on 105 planted real-repo bugs
PawelHuryn · x · 2026-09-11
Pawel Huryn launched Bug Hunt Bench, a blind-graded leaderboard pitting frontier coding models against 105 real planted bugs in actual repos, with one prompt per repo and continuous updates.
- The board offers score-vs-cost and score-vs-time views: costs span roughly 200x (log axis required), while runtimes stay under 7x (linear axis).
- Features include ceiling-run filtering, best-per-lab views, superseded historical runs, and PNG export; the same model can appear multiple times across reasoning tiers and harnesses.
- The author also shared a view with all OpenAI models selected, responding to a question about the Terra xhigh tier (it exists, just hidden by default filters).
