Anthropic: Claude Fable 5.2 designs working electronic hardware end to end
EricBuess · x · 2026-11-10
Anthropic reports Claude Fable 5.2 can now design and prototype electronic hardware end to end. A year ago, models trained with Diode Computers couldn't reliably lay out PCBs; now, with minimal prompting, Fable 5.2 designed a speakerphone, a voice-assistant hub, and a handheld virtual pet — doing geometric reasoning for board layout, anticipating manufacturing constraints, revising its own work, CAD modeling, and directing engineers to build prototypes whose circuitry needed no fixes.
