BenchCAD

Can the AI do mechanical design as code? Given a drawing or a description of an industrial part — a gear, a spring, a drill bit — it has to write or edit the parametric CAD program that builds it, and the program is run to check the shape really comes out right. Higher is better.

GPT-6 Astra by OpenAI holds the best BenchCAD result among tracked models, at 95.9% (released Sep 3 2026). Higher scores are better on this benchmark.
