Claude Fable 5.2 designs three working electronic prototypes from short briefs
Anthropic and Diode Computers tested Claude Fable 5.2 on end-to-end hardware design. From short briefs, it produced circuit boards, enclosures, firmware and parts lists for a speakerphone, voice-assistant hub and handheld virtual pet. All three prototypes worked without electrical modifications, though commercial durability and certification remain untested.
