The article presents a benchmark comparing the performance of various AI coding tools, including Google Antigravity 2.0, ModelRift, Codex 5.5 High, Claude Sonnet, Cursor Composer, and Claude Opus, in generating a 3D model of the Pantheon using OpenSCAD. The benchmark evaluates the tools' ability to turn architectural reference material into parametric CAD code. Google Antigravity 2.0 topped the benchmark, but its rollout has been criticized for disrupting users' workflows. The article highlights the importance of OpenSCAD as a target language for LLM-generated geometry.
