How this is ranked
AI models ranked by Design Arena Elo in the 3D category — generating three-dimensional scenes and geometry as code (Three.js, WebGL, shaders), judged head-to-head by humans. This is the most demanding category in the arena: the model has to reason about space, lighting and camera all at once.
