skyfallai 发布 SKY-001：用 3D 分层规划生成可制造的物理产品设计
skyfallai 的 SKY-001 能直接产出零件树和构建步骤的 3D 设计，CAD 精度追平 GPT-6 Astra，成本只有 1/150，做硬件设计的朋友可以看看。
@skyfallai 发布 SKY-001，面向物理产品设计，以 3D 方式规划零件与构建步骤。该模型在 CAD 精度上追平 GPT-6 Astra，单次设计成本约为其 1/150。输出包含完整零件树、每个操作的草图以及各中间实体。架构分两阶段：Hierarchical Composer 生成整体对象并展开为装配体与零件，Construction World Model 预测每个叶子零件的可视化构建步骤。
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.
