Antigravity 2.0 Leads the OpenSCAD Architectural 3D LLM Benchmark

The OpenSCAD Architectural 3D LLM Benchmark tests model ability to produce correct, compilable OpenSCAD — a code-first CAD language used for parametric 3D modeling. It is a narrower, harder signal than general coding benchmarks because outputs must satisfy geometric constraints, not just pass a unit test.

Antigravity 2.0 leads the benchmark rankings according to the team at ModelRift. The result matters because OpenSCAD generation is a practical proxy for spatial reasoning and structured code synthesis under domain-specific constraints. A model that handles OpenSCAD well is one that understands geometric relationships, coordinate systems, and declarative construction patterns — capabilities that are directly relevant to tooling for CAD automation, generative design pipelines, and hardware-adjacent software.

For engineers working at the intersection of LLMs and physical-world tooling, benchmark differentiation at this layer is more actionable than general MMLU or HumanEval scores. CAD code generation has failure modes that differ from web or systems code: a syntactically valid script can still produce non-manifold geometry or degenerate shapes. Any benchmark that captures that class of error provides a tighter signal.

Antigravity 2.0 is the model to evaluate first if your use case involves parametric design generation, automated part modeling, or any pipeline where structured spatial output is the artifact. The benchmark methodology and full leaderboard are published by the ModelRift team, and engineers building in this space should treat those results as a starting reference rather than a final word — domain-specific fine-tuning on target geometry types will likely shift rankings for production workloads.

The practical takeaway: spatial code generation is now testable at a benchmark level, and Antigravity 2.0 currently sets the baseline to beat.
