RecupBuild combines three Meta model families through the Meta Model API.

Muse Spark (muse-spark-1.3) reads the photo, names each material, estimates thickness, invents parametric projects, writes the assembly steps and breaks down finished objects in Rebuild. Every call uses structured output with a JSON schema, so the server receives data it can validate.

SAM 3.1 traces the wood, the metal and the A4 sheet with text prompts. We decode each mask, compute the tightest rotated rectangle, and match it to the piece Muse Spark identified. The piece keeps its kind and thickness and takes SAM's real edges. If SAM fails, the scan falls back on Muse Spark's corners.

Muse Image (muse-image-1.0) uses the user's photo as a reference to show the finished object in their real material. It is labelled as an illustration; the sizes remain those of the engine.
