While designing complex physical objects via CAD, frontier LLMs try to brute-force engineering through text tokens and inevitably buckle under compounding error pile-up. SKY-001 operates as a true spatial World Model. It plans directly in the 3D space, recursively breaking complex designs down to the smallest part, then re-assembling everything while keeping every step globally consistent. That’s how it leaves GPT-6 Astra, Gemini 4 Argon, and Claude Fable 5.1 behind on complex CAD workflows. Here’s a side-by-side look at a Jaguar E-type sports car and a Ducati Cafe Racer:
