Skyfall AI 推出了 SKY-001 工程世界模型，能够通过 3D 规划零件和构建步骤来设计物理产品。该模型分为两阶段，通过 Hierarchical Composer 生成整个对象并将其展开为装配体和零件，再由 Construction World Model 预测构建每个叶子节点的视觉步骤。其 CAD 精度与 GPT-6 Astra 相当，但每个设计的成本降低了约 150 倍。
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.
