OpenAI Engineers Build Hardware Prototype in Days Using GPT-6 and Astra

TEHRAN, Nov 4 (OPA) — OpenAI announced that a side project by two internal engineers resulted in a fully functional hardware device connected to Codex, developed in under a week. The project encompassed custom body design, printed circuit board layout, firmware development, and software integration. The company stated the experiment evaluated whether AI models could independently manage end-to-end hardware development stages.

During the process, GPT-6 defined the initial requirements and guided the design framework, while the Astra model handled the majority of engineering tasks. Astra executed the device exterior design, internal component selection, printed circuit board architecture, and electrical connection mapping. Following the digital design phase, an external manufacturer produced a limited run of physical prototypes within a month.

Despite the rapid design timeline, developers encountered production hurdles as Astra initially failed to account for physical manufacturing constraints and part tolerances. Human engineers intervened across multiple phases to refine assembly requirements. OpenAI noted that internal infrastructure teams already utilize ChatGPT and Codex for generating CAD models, preparing technical production blueprints, and configuring engineering simulations.

To further test model utility in industrial settings, OpenAI expanded partnerships with Chip Ganassi Racing and automotive manufacturer Mazda. The collaboration with Chip Ganassi Racing focuses on converting 3D scans into editable CAD models for legacy part reproduction. Meanwhile, the Mazda research partnership explores AI applications in automotive aerodynamics and crash safety engineering.
