Gemini 3.7 Generates a 3D Rolex in Pure Three.js for Just $0.038

AI/ML API conducted a hardcore code generation test on Google's new Gemini 3.7 model: using a single prompt, they asked the model to build a gold luxury watch entirely in pure Three.js.

The results were stunning. Without any external assets or textures, the model generated the complete watch procedurally in one shot. This included the fluted bezel, sunburst dial, date window, and sweeping seconds hand. The total cost for this generation was merely $0.038.

The creator noted that Three.js is an excellent testbed for model capability because the model cannot hide behind pretty static pixels; the generated code must describe an actual 3D scene that survives physical rotation from any angle.
