OpenAI says GPT-6 Astra designed a working test device in under a week
OpenAI says two team members, working on it as a side project, used GPT-6 Astra to design a device for talking to Codex in under a week, with the model designing the enclosure and circuit board, choosing components and writing the firmware; a contract manufacturer built a small batch of prototypes in under a month. OpenAI says getting it ready for manufacturing still took several rounds of review, because Astra did not consistently account for the manufacturer's production limits, tolerances or assembly details. Its hardware teams use Codex and ChatGPT for CAD models, manufacturing drawings and simulations, and it is testing workflows with Chip Ganassi Racing and Mazda. These are OpenAI's own accounts, not independent tests.

Why it matters: If your team does mechanical or electronics design, try these models on routine steps such as turning 3D designs into 2D drawings or setting up simulations. Keep an engineer checking manufacturability, since that is where OpenAI says the model fell short.
