Open-source software called LDraw Nova allows AI models to design LEGO builds containing over 2,000 real pieces. Developers can use this tool with general models like GPT-6 Astra and Claude Opus 5.5 to create detailed CAD files from simple prompts. For example, a prompt asking for "the most beautiful model that comes to your mind" resulted in the 2,175-piece Sakura Garden design. The system uses Python tools to write programs that generate the build data without placing every single brick physically. Developer Carlos Antelo noted that none of these designs have been built with actual bricks yet, as he "didn’t even try."<\/p>\n

<\/p>\n

The technology works by having an AI agent write a plan in JSON format and then generate a Python program to output LDraw source files. This approach avoids complex geometry math because agents are better at generating code. The project runs as a Docker web app compatible with various AI providers. While the tool can inspect and adjust designs until they are complete, Antelo admitted that "physics modeling is something Nova is currently lacking," meaning stability is not yet guaranteed. He estimated it would cost around $5 in token fees to build one Technic mechanism using Astra.<\/p>\n

Antelo aims to create tools usable by low-end agents for iterative building, though he recommends higher-end models for accuracy. The project differs from Carnegie Mellon University’s BrickGPT, which checks designs for physical stability during generation. Future goals include designing minifigures and Technic machines, potentially bridging the gap between digital code and physical objects through 3D printing or robot assistance. Currently, users can try designing their own LEGO sets that exist only in computer files.<\/p>\n
