How this is ranked
AI models ranked by Design Arena Elo in the UI-component category — generating individual interface components (buttons, forms, modals, cards) rather than whole pages, judged head-to-head by humans. Component work is where most frontend time actually goes, and it rewards different things than page generation: consistent spacing, sane state handling and styling that matches the surrounding system.
