Interactive Lamp Build Comparison: Fable 5.1, GPT-6 Astra, and Grok 4.6

This article compares the parts lists and build strategies proposed by Fable 5.1, GPT-6 Astra, and Grok 4.6 to implement concept 3D renderings as actual interactive desktop lamps. Each model presented an assemblable hardware configuration utilizing commercial components such as Raspberry Pi, ESP32, and servo motors.

Hardware Configuration by Model

Fable 5.1 proposed a total of 18 components based on the Raspberry Pi 3 Model A+ and a Waveshare 2-inch LCD. It uses a 4-pack of Deegoo-FPV MG996R servos and a HiLetgo PCA9685 driver to implement pan/tilt head functionality, with a parts cost of $231.86. The estimated lead time is 2–5 days.

Grok 4.6 presented a 15-component configuration centered around the XIAO ESP32-S3 Sense and OV2640 camera. It controls base Yaw and shoulder Lean movements using two MG996R servos and includes a WS2812B LED ring and a 470 µF capacitor. The parts subtotal is $166.85, bringing the total to approximately $193.79 when including the cost of a PLA 3D-printed body. The lead time is 3–8 days.

GPT-6 Astra adopted an approach using a stock pan/tilt kit and placing a small display on a rear-fixed platform. While GPT-6 Astra generated the 3D models and animations, actual fabrication and score verification were not performed.

Evaluation Criteria and Limitations

The evaluation criteria consist of basic functionality (30 points), advanced functionality (20 points), cost (20 points, ideally under $250), ease of manufacturing/assembly (20 points), and lead time (10 points). All designs are merely proposals generated in a single pass, and their actual functionality or safety has not been verified. The estimates for Fable 5.1 and GPT-6 Astra are as of September 11, 2026.
