OpenSCAD LLM Benchmark: Building the Pantheon
Summary
ModelRift's OpenSCAD LLM benchmark, Pantheon, pits six AI coding tools against a parametric CAD task to build the Pantheon in OpenSCAD. The study highlights how OpenSCAD's text-based scripting favors structured, parametric geometry for AI generation, with autonomous results ranging in quality and speed. Antigravity 2.0 / Gemini 3.5 Flash High leads in autonomous quality, while others show a mix of strengths and export issues; human-in-the-loop annotation remains crucial for spatial accuracy.
