A structured-prompt comparison of Opus 5.5 and Sonnet 5.5 building a 3D steampunk whale scene (Blender + three.js). Sonnet 5.5 used 1.68M output tokens ($109 API equivalent) vs Opus 5.5's 2.50M ($156). Verdict: Sonnet 5.5 overperformed but still trails Opus; official benchmarks say nothing about 3D.
