Testing Claude on real-world electronics design
Summary
- Anthropic and Diode Computers tested Claude Fable 5.2 on end-to-end hardware design, successfully building a speakerphone, a voice-assistant hub, and a handheld virtual pet.
- Fable 5.2 demonstrated advanced geometric reasoning for circuit board layouts, scoring 69% on Diode's PCB Gym benchmark and 83.5% on BenchCAD 2.1.
- The model autonomously self-corrected design errors, wrote custom routing algorithms, checked component datasheets, and managed mechanical CAD models and firmware.
- Diode manufactured the resulting circuit boards directly from Claude's design files without requiring intermediate engineering fixes.
Why it matters
Demonstrating end-to-end electronic hardware design, PCB routing, and firmware generation highlights a major capability leap in frontier AI models for complex real-world engineering tasks.
