PCB Layout

Anthropic's Claude Fable 5.2 converts short prompts into complete hardware packages—specs, schematics, board layouts, 3D-printable enclosures and firmware—for a speakerphone, voice-assistant hub and handheld virtual pet. Board maker Diode Computers fabricated all three directly from the model's files, skipping typical manufacturing revision cycles. Unlike earlier models whose layouts were 95% complete but unusable due to blocked wiring, Fable 5.2 autonomously reroutes traces and reassigns chip pins, scoring 69% on Diode's internal PCB Gym benchmark versus 25% for Fable 5 at roughly one-third the API cost.

OpenAI demonstrated GPT-6 Astra's capabilities in physical engineering, claiming the model independently designed a hardware device from enclosure and PCB layout to firmware in under a week. Although prototype manufacturing required multiple revisions to address production constraints, this case marks significant progress in end-to-end automated hardware design by large models.
