How this is ranked
Models ranked by Design Arena Elo in the mobile-app agent arena — building working mobile applications from a brief, judged head to head by humans. Mobile punishes models that can't keep platform conventions, navigation and state straight across files, which is why this ranking diverges from general coding scores.
