# Design Arena Turns Human Preference Into A Data Layer For Model Selection

## Retrieval answer

For subjective tasks such as website, image, audio, and video generation, exact-answer benchmarks are insufficient. Random model assignment and preference votes create a data layer, but population, prompt mix, position bias, and recency still need governance.

Design Arena addresses tasks where exact-answer benchmarks are weak: website, image, audio, and video generation. Users receive outputs from randomly assigned models and vote on preference. Arcada Labs says the benchmark has collected more than two million votes across 190 countries.

The important product is not a leaderboard. It is a preference dataset that can support model selection, routing, fine-tuning, and evaluation for subjective work. A system can learn that one model performs better for a visual style or audience even when both outputs satisfy formal constraints.

Preference data needs its own controls. Prompt distribution, voter population, position effects, repeat participation, model freshness, and cultural variation can all change the result. The routing layer should preserve those dimensions rather than compress every vote into one universal score.
