## Summary

Anthropic and Diode Computers tested Claude Fable 5.2 on designing three electronic devices: a speakerphone, a voice-assistant hub, and a handheld virtual pet. Claude laid out the circuit boards, wrote firmware, and prepared parts lists, and Diode built working prototypes without circuit fixes. On the PCB Gym benchmark, Fable 5.2 scored 69% versus 25% for Fable 5. Anthropic says the prototypes have not been tested for certification or mass production.

## Why it matters

The source shows how Claude handled placement, routing, and manufacturing checks on real circuit boards, with benchmark scores comparing it to earlier models.
