INDEPENDENT EVALUATION · HUMAN-JUDGED BENCHMARKS

Testing AI on taste.

We benchmark frontier models on the judgments working creatives make every day: which cover, which crop, which line of copy. Every item is judged blind by a panel of professionals, and we build every benchmark in-house.

We evaluated Anthropic’s new Claude Opus 5.5 across the FrontierTaste suite. In this preview it leads the FrontierTaste Benchmark and Layout Critique.

Motion remains its weakest discipline: in most disagreements with the panel it prefers the busier animation, and its written reasons rarely mention timing.

HOW WE SCORE

Five working professionals judge every pair, blind. A model scores only when it agrees with them.
