SKY-001 世界模型可从一张照片生成工程设计的零件树和建模步骤
Skyfall AI 出了个专做工程设计的 SKY-001，一张发动机照片就能拆出五层零件树和建模步骤，成本比通用 LLM 低 150 倍。
Skyfall AI 发布工程领域世界模型 SKY-001，输入一张发动机或汽车照片即可输出完整的装配零件树，并给出逐步的草图与建模操作序列。公司称该专用模型在 CAD 和户型图设计上的成本比最强通用 LLM 低 150 倍到 185 倍，同时精度相当。架构上由两个模型分工：Hierarchical Composer 逐层判断物体由哪些部件构成，Construction World Model 则按有序视觉状态推演每个末端零件，包括每次操作后的实体和连接两步的 2D 草图。从一张 VMS-85 发动机照片出发，模型生成了五层零件树，能还原隐藏在外壳内的轴套和轴。
World models have mostly been used to generate games, video and robot training scenes.
But SKY-001 released a world model for solving engineering design: it turns 1 photo of an engine or car into a full tree of parts, plus the step-by-step sketches that build each one.
Skyfall AI says a specialist world model beats the strongest general LLM on CAD and floor-plan design cost by 150x to 185x while matching its accuracy.
It takes an image of a product, unfolds it into a tree of assemblies and parts, then predicts the sketch-and-operation sequence that builds each part.
Two models share the work. A Hierarchical Composer decides what the object is made of, one level at a time. A Construction World Model rolls out each leaf part as ordered visual states: the solid after each operation, plus the 2D sketch that turns one state into the next.
From a single photo of a VMS-85 engine, the composer produced a five-level part tree, down to sleeves and shafts hidden inside housings.
