BrickGPT

Why we included this project

BrickGPT turns a text prompt into a toy brick model you can actually snap together, rather than a render that merely looks plausible. The generation pipeline bakes in stability and connectivity constraints, and the output comes as LDraw files plus brick-by-brick text layouts that any LDraw-compatible tool can open. For people working on 3D assembly or procedural modeling, it's a solid reference for how to fine-tune an LLM to emit constrained structural sequences instead of free-form geometry. The repo bundles inference, a Gradio demo, per-brick texturing, and a mesh-to-brick converter, so the whole path from prompt to a design ready to print or build is covered. One caveat: the recommended physics-based stability check runs on Gurobi, which requires a license, though a lighter fallback mode exists.
