AI · First reported 3 Nov, 20:15 · Updated 20:40

OpenAI says GPT-6 Astra helped design a device for interacting with Codex in under a week. The reports describe broad model involvement in design and software, while noting that manufacturing required further engineering revisions.
- OpenAI says the side project produced a device that connects users with the Codex coding agent; GPT-6 and Astra were involved in its design.
- Astra’s reported work included the enclosure, circuit board, component selection, firmware, and user interface. A contract manufacturer made a small prototype batch in under a month.
- OpenAI reported BenchCAD 2.0 scores of 0.875 for a newer internal model and 0.594 for GPT-6 Astra at its highest reasoning setting; it did not identify the internal model.
