Bug Hunt Bench Adds Per-Model Bug Coverage View; Hunyuan Sits on the Price-Performance Frontier

Pawel Hyrun added a Coverage view to Bug Hunt Bench—a blind-graded board testing frontier coding models against 105 real planted bugs—showing which bugs each model fixes, with filters and PNG export.

He earlier assessed Tencent Hunyuan as "not a breakthrough, but yet another solid partner for everyday coding": putting aside its high Luna scores, it sits on the price-performance Pareto frontier with open weights. The board also offers score-vs-cost and score-vs-time views, with roughly a 200x cost spread across runs.
