OpenAI staff had GPT-6 Astra design a physical hardware prototype in under a week
APPSO · wechat · 2026-11-08
APPSO breaks down OpenAI's Nov 3 progress report on AI-assisted physical engineering. Two OpenAI employees handed shell structure, PCB, UI and firmware design entirely to GPT-6 Astra, producing a Tamagotchi-like voice Codex device prototype in under a week, with a contract manufacturer delivering sample units within a month.
Key points:
- Astra handled mechanical, electrical and firmware design, but failed to consistently account for manufacturing constraints, tolerances and assembly details, requiring several review rounds before production;
- Codex token usage in OpenAI's internal hardware team grew 23x since Feb 2026; the new BenchCAD 2.0 benchmark scores 0.875 for the internal model vs 0.594 for GPT-6 Astra;
- Industry side: Chip Ganassi Racing converts 3D scans to CAD drawings with AI, Mazda uses Astra for aerodynamic variant simulation, Siemens launched Fuse EDA AI Agent, IBM and Dallara cut aero simulation from hours to under 10 seconds;
- The piece coins "Agentic Hardware Engineering": future hardware moats may lie in the manufacturing and test data AI can access.
