OpenAI's GPT-6 Astra designed a working gadget: what it did and where it fell short
Quick answer
OpenAI says it used GPT-6 Astra to design a small device for talking to Codex, covering the look, the enclosure, the circuit board and the firmware, with no direct human edits (OpenAI, Nov 3). Two staffers did it as a side project in under a week, and a contract manufacturer built prototypes in under a month. It still needed several rounds of fixes before it was ready to manufacture.
What Astra did
- Requirements and look: wrote the functional spec and styled the device.
- Mechanical: designed the enclosure and the internal parts that hold components.
- Electrical: picked components and laid out the printed circuit board to fit the case.
- Software: built the interface and the firmware that connects it to Codex.
Where it fell short
- OpenAI says Astra “did not consistently account for” the manufacturer’s production limits, tolerances or assembly details. Humans had to review and iterate.
The bigger signal
- Usage: token use across OpenAI’s hardware teams is up 23x since February.
- Benchmark: on BenchCAD 2.0 (rebuilding 3D parts and reading circuit boards), a newer internal model scored 0.875 versus 0.594 for GPT-6 Astra.
- Partners: Chip Ganassi Racing is turning 3D scans into CAD drawings with it, and Mazda is testing it on aerodynamics and crash-safety design.
FAQ
- Can I buy the device? No. OpenAI calls it a test device.
- Does this replace hardware engineers? Not per OpenAI’s own account. Engineers still reviewed the output and fixed what Astra missed.
- Who gets these engineering tools? OpenAI is testing them with a small group of industry partners and has a sign-up form for engineers and firms.
