TL;DR
Antigravity 2.0 outperforms competing AI models in a benchmark testing their ability to generate OpenSCAD code for architectural structures. The result highlights advancements in AI’s spatial geometry handling. Details on the full scope of the performance gap and implications are still emerging.
Antigravity 2.0 has topped the OpenSCAD Architectural 3D LLM Benchmark, outperforming other AI models in generating detailed parametric CAD code for the Pantheon. This achievement underscores significant progress in AI’s ability to handle complex spatial geometry tasks relevant to architecture and 3D modeling.
The benchmark involved multiple AI coding tools tasked with creating an OpenSCAD model of the Pantheon based on reference images, with the goal of accurately capturing architectural features such as the rotunda, dome, portico, and columns. Among the six tested models, Antigravity 2.0 achieved the highest overall score, demonstrating the strongest autonomous performance with detailed and dimensionally accurate outputs.
Specifically, Antigravity 2.0 generated a model that incorporated real Pantheon dimensions, including the inscription and coffered ceiling pattern, with a high level of detail and architectural fidelity. The model completed the task in approximately 12 minutes, with a score of 4.5 out of 5 for quality, marking a notable improvement over previous models like Claude Code, Cursor, and others.
Why It Matters
This development is significant because it indicates that AI models are increasingly capable of understanding and generating complex, parametric architectural geometry. Such advances could impact design workflows, automated modeling, and CAD applications, making AI a more practical tool for architects and engineers working with hard-surface, constructive models. The ability to produce detailed, reproducible code directly from natural language prompts could streamline design iterations and reduce manual effort.

Background
The benchmark was designed to test AI models’ ability to translate architectural reference images into OpenSCAD code, focusing on structures with regular, constructive features suitable for parametric modeling. Previous models could handle simple shapes but struggled with complex, multi-component buildings like the Pantheon. OpenSCAD’s text-based approach makes it an ideal target for AI-driven geometry generation, as it emphasizes logical, nested commands over graphical UI interactions.
Earlier efforts in this space have shown incremental progress, but Antigravity 2.0’s performance marks a notable leap, especially in autonomous generation quality and accuracy. The benchmark results are relative and serve as a snapshot of current capabilities, with ongoing developments expected to further improve AI spatial reasoning and code generation fidelity.
