DesignArena is a web platform for comparing AI-generated creative work and exploring model leaderboards. Its methodology describes randomly selecting models, giving them the same prompt, and presenting their outputs anonymously for community voting. Pairwise comparisons feed rankings calculated with a Bradley–Terry model. The site covers multiple task areas, including websites and web apps, images, games, slides, mobile apps, 3D assets, video, and text-to-speech. It also offers AI creation workflows alongside its benchmark leaderboards.
