What it measures vs what it misses

✓ Measures

Completeness, visual quality, and interactivity for generated UI tasks.

✗ Misses

Full product design review. Accessibility audits beyond the benchmark rubric.

Why this countsIt tells you whether the model can generate, repair, and reason over code under evaluator pressure rather than marketing examples.Same-test ruleThis percentile only compares models inside the exact benchmark/version group shown here. It is not a universal score.What it missesIt does not fully capture repo-scale iteration, IDE ergonomics, or long debugging loops.
