Skyfall AI's SKY-001 world model turns sketches into CAD builds in 3.9s, vs 199s for GPT-6 Astra

Skyfall AI unveiled SKY-001, billed as the first Engineering World Model, moving world models beyond robotics and video into engineering software: a text prompt or 2D sketch becomes a full CAD build sequence that opens directly in Autodesk Fusion.
Key points:
- Speed: 3.9 seconds per case vs 199 seconds for GPT-6 Astra.
- Approach: plans visually instead of repeated LLM calls — first splitting an object into sub-assemblies and individual parts, then a construction world model predicts the ordered sketches and 3D solid states for each part, structure LLM-generated shapes typically lack.
- The team argues complex real-world engineering design is orders of magnitude harder than next-token prediction, hence the deliberately different research path; a researcher walkthrough video is available.
