Pawel Huryn launched Bug Hunt Bench, a blind-graded leaderboard testing frontier coding models on 105 real planted bugs with one prompt per repo. He questions why the K3.1 Pro launch evaluated coding benchmarks inside Claude Code, noting that in his tests Kimi K3 on Moonshot's own CLI cost 2.9x more than Claude Code. The board supports score-vs-cost/time/turns views, with all data open-sourced on GitHub.
