SKY-001

SKY-001 is the first Engineering World Model from Skyfall AI, a world-model based system that breaks a complex physical object into manageable parts and keeps them consistent across hundreds or thousands of construction steps. It does not do next-token prediction like an LLM: a hierarchical composer decides what the design is made of, separates it hierarchically and generates the whole design part by part.

It works in four stages. Stage 1 converts a 2D image or text prompt into several rough 3D assets at once, so the user can explore visual directions and pick a foundation. Stage 2 breaks the selected design into smaller individual parts, from large structural pieces down to tiny screws and fasteners. Stage 3 recreates how a real designer works step by step, drawing precise 2D sketches stroke by stroke, then stretching, cutting or shaping them into finished 3D objects. Stage 4 assembles all the parts layer by layer in hierarchical order into a complete 3D assembly viewable in a standard 3D asset viewer.

Access is by waitlist: the site says to join the waitlist to be the first to hear when it goes public. The vendor positions it for complex real-world objects with hundreds of thousands of parts, and claims frontier-level accuracy at 100 times the speed and 1/150th the cost of LLMs. The page's numeric comparison table renders inconsistently (it shows 0x faster and a 0.7 percent accuracy figure against an LLMs best IoU of 79.1 percent), so those table figures are not repeated here.
