The cost and quality frontier across 29 AI coding models
Based on 29 AI models, 60 real engineering jobs, and 1,740 graded answers. We tested 29 AI models on the same 60 real engineering tasks, graded every one of the 1,740 answers against criteria written before any model ran, and priced every run. That combination, quality and cost measured together on the same work, is what this research is about.Four findings matter for anyone deciding what AI models to buy for their engineering teams.
