OpenAI says GPT-6 Astra designed a hardware device from scratch in under a week

OpenAI's hardware team used GPT-6 Astra to design a device for the Codex coding agent in under a week, handling everything from the enclosure to the circuit board to the firmware. Several revision rounds were needed before production because the model didn't always account for manufacturing tolerances. A newer internal model scores significantly higher on OpenAI's engineering benchmark, though the company isn't sharing details.
