OpenAI GPT-6 Astra Launch - BenchCAD (with tools): leaderboard
BenchCAD row of the professional table in OpenAI's GPT-6 Astra launch post (2026-09-03): models reconstruct 3D objects from multi-view renders by writing CAD code, run with tools. Geometric-overlap score in percent, higher is better. Only OpenAI's runs (GPT-6 Astra, GPT-5.6 Sol) are kept; footnote 5 marks the Claude values as Anthropic-reported under a modified protocol.
Metric: Geometric-overlap score (%). Source: openai.com. Saturation forecast: Around February 2027. 2 models tracked.
