OpenAI’s November 3 engineering update describes GPT-6 Astra helping design a device that connects to Codex: enclosure, circuit board and software integrations. Two team members worked on the test as a side project for less than a week; a manufacturer built prototypes in under a month.

Manufacturing still needed review

OpenAI says several review cycles were needed because Astra missed production limits, tolerances and assembly details. Its expanded Chip Ganassi Racing work and new Mazda research collaboration retain engineer review.

An unnamed internal model

On vendor-run BenchCAD 2.0, OpenAI reports 0.875 for a newer internal model versus 0.594 for GPT-6 Astra at its highest reasoning setting. The company does not name that model here. These results establish neither a public successor nor independent evidence of production readiness.
