P3D-Bench - Text-to-3D Parametric Judge: leaderboard

Metric: MLLM-judge bucket score (0-100) (Gemini 3.1 Pro rates rendered views for semantic, geometric and aesthetic similarity and answers specification-derived QA) on 400 Text-to-3D cases from parametric specifications (minimal JSON and OpenSCAD outputs), the model writes a parametric CAD program that is compiled, meshed and aligned to the ground truth; invalid outputs take the worst value; each general model runs with its maximum thinking budget; averaged over the output formats; higher is better. Source: arxiv.org. Saturation forecast: Around December 2026. 9 models tracked.
