World models are moving past generating scenes to look at, to generate things you can build.
@skyfallai released SKY-001, a model that designs physical products by planning parts and build steps in 3D, and it matched GPT-6 Astra’s CAD accuracy at about 150x lower cost per design.
SKY-001 outputs a design along with the ordered sequence that builds it: a part tree, the sketch for every operation, and each intermediate solid.
Two stages do the work.
- a Hierarchical Composer generates the whole object and unfolds it into assemblies and parts.
- a Construction World Model then predicts the visual steps that build each leaf, with its parent as context.
