Building taste into creative AI

Contra Labs brings together private evaluations, public comparisons, and research outputs under one unified human evaluation framework.

Blind comparative reviews

Models are evaluated head-to-head through structured, bias-controlled comparison protocols.

Expert preference modeling

We capture and analyze high-signal human preferences from vetted creative professionals.

Creative scoring systems

Qualitative judgment is translated into structured scoring frameworks aligned with real-world standards.

Multimodal AI evals

We assess image, video, design, and interactive model outputs where traditional metrics fail to capture taste.
