Antigravity 2.0 Tops the OpenSCAD Architectural 3D LLM Benchmark

Antigravity 2.0 has achieved the highest score in the latest OpenSCAD architectural benchmark, demonstrating superior capability in translating architectural reference images into parametric CAD code. This marks a significant advancement in AI’s ability to handle complex spatial geometry, with implications for CAD automation and architectural design tools.

The benchmark involved multiple AI models tasked with creating a detailed OpenSCAD model of the Pantheon based on reference images, using the OpenSCAD CLI for rendering and iteration. Antigravity 2.0, developed by a leading AI research team, scored the highest among six tested models, with a score of 5.5 out of 6, reflecting both accuracy and detail density.

Other models, such as Claude Code, Google Antigravity 2.0, and ModelRift, scored lower but showed varying strengths in structure, detail, and speed. Notably, Antigravity 2.0 was the only model to incorporate real dimensions, inscriptions, and the interior coffered ceiling pattern, indicating a high level of spatial reasoning and parametric control.

Why It Matters

This development underscores a major step forward in AI-driven architectural modeling, especially in parametric design and constructive geometry. It suggests that future AI tools could automate complex CAD tasks, reducing manual effort and increasing precision in architectural workflows. For industries reliant on detailed 3D modeling, this progress could accelerate design cycles and enhance customization capabilities.

Background

The benchmark was designed to evaluate AI models’ ability to generate architectural models in OpenSCAD, a text-based CAD language optimized for constructive, parametric shapes. Previous models could handle simple geometries but struggled with complex structures like the Pantheon, which features radial symmetry, domes, and detailed facades. The competition included models like Claude Code, Google Antigravity, and ModelRift, with scores indicating varying levels of success. The emergence of Antigravity 2.0 as the top performer marks a notable milestone in this ongoing development.
