How this list is built
Generated from the dataset on every refresh. Nobody picks the order by hand.
Models by their Design Arena: UI components result, as the board publishes it, best first. Design Arena shows people two designs made by two models from the same prompt (a UI component) and asks which is better. The number is the Elo rating built from those votes, as Design Arena publishes it.
