TL;DR
Antigravity 2.0 achieved the highest score in a recent OpenSCAD benchmark for architectural modeling, outperforming other AI systems. The test involved generating a parametric model of the Pantheon using reference images. This marks a significant step in AI’s ability to handle complex geometric tasks.
Antigravity 2.0 has been confirmed as the top performer in a recent OpenSCAD architectural benchmark, outperforming other AI coding tools in generating a parametric model of the Pantheon from reference images. This achievement underscores advances in AI’s spatial reasoning and geometric modeling capabilities, with implications for CAD automation and architectural design.
The benchmark involved multiple AI models tasked with creating an OpenSCAD script that accurately represented the Pantheon, including its rotunda, dome, portico, columns, and pediment, based on two reference images. Among six models tested, Antigravity 2.0 delivered the highest score, with a detailed and dimensionally accurate model that incorporated real-world measurements and architectural features.
The test used the OpenSCAD CLI to render previews and evaluate the models. Antigravity 2.0’s output was distinguished by its precise use of dimensions, inclusion of detailed features like the inscription and interior coffered ceiling, and overall structural coherence. It took approximately 12 minutes to generate the model, which was rated 4.5 out of 5 for quality.
Why It Matters
This development is significant because it demonstrates that advanced LLMs like Antigravity 2.0 are capable of handling complex spatial and architectural reasoning tasks, moving beyond simple syntax to produce detailed, parametric 3D models. Such capabilities could accelerate CAD workflows, improve automation in architectural design, and enhance AI’s role in engineering and 3D printing.

Background
The benchmark was designed to evaluate how well AI models can translate architectural reference material into parametric CAD code using OpenSCAD, a text-based modeling language. Previous models could handle basic shapes but struggled with complex compositions like the Pantheon. The test reflects ongoing efforts to improve AI’s understanding of spatial relationships and constructive geometry in CAD environments.
Antigravity 2.0’s success builds on recent advancements in large language models and their ability to reason about geometry, with prior benchmarks focusing on simpler shapes. This marks a notable step forward in AI-driven architectural modeling and parametric design automation.
