Anthropic tok say im Claude Fable 5.2 model don reach level where e fit design and prototype electronic hardware from start to finish, after the company work with Diode Computers to test am. The company say the model design three devices—a speakerphone, a voice-assistant hub, and a handheld virtual pet—and human engineers build prototypes wey work without any fix to their circuitry.
For the speakerphone, Anthropic give Claude Fable 5.2 one simple prompt: make a puck wey go plug into computer over USB-C, get microphones and speaker, and support Bluetooth with antenna on printed circuit board. The model write the device specifications, draw clean schematic, choose where components go on printed circuit board, route copper connections between them, design 3D-printable enclosure, write firmware, and prepare parts list. Diode Computers assemble the boards and run the firmware under the model direction. The speakerphone prototype still dey work after weeks of use.
Claude Fable 5.2 go through similar process for the voice-assistant hub and the handheld virtual pet, and Anthropic say both still dey work well. The company note say the devices na early prototypes, so e never know how dem go hold up with continued use or whether dem go pass commercial certifications.
Anthropic say the biggest difference between Claude Fable 5.2 and the models from earlier test na how well e take reason through complex geometric problems. The earlier models no fit reliably lay out circuit board or design components wey fit together, according to the company.
Anthropic also claim say Claude Fable 5.2 create one functional prototype operating system within eight days, with more than 1,000 dedicated AI agents collaborating to craft and evaluate the code.
