Visual / Spatial Reasoning

Interactive Cozy Living Room

A short prompt asks the model to make a cozy 3D living room with a sofa, TV, fireplace, lights, and simple controls. Generating a 3D scene is not just about listing objects: the model has to reason about how the room is actually structured, from furniture direction to where the fireplace and TV belong.

Prompt

Create an interactive 3D cozy living room scene using Three.js (ES modules, v0.160) with a TV playing animated Tom & Jerry SVG content.

Fortytwo Prime

Fortytwo

PASS4 / 4

Fortytwo renders a usable 3D room, keeps the furniture relationships coherent, uses warm fireplace and lamp lighting, and shows animated TV content.

vs
Claude Opus 4.8Anthropic
MIXED3 / 4

Claude Opus 4.8 renders a usable warm living room with cozy lighting and visible Tom & Jerry-style TV content. However, the sofa faces the opposite direction from the TV, so the main room layout fails the spatial-coherence check.
