Show HN: Made an open-source Lego AI generator
A developer has released an open-source tool that uses AI agents to generate LDraw LEGO models based on user prompts. The project utilizes Docker and semantic search to assist LLMs in creating complex 3D CAD designs.
Why it matters
It demonstrates the potential for LLMs to handle precise, low-level spatial and mathematical tasks, expanding the utility of AI in physical design.
Give an AI agent a model idea. Guide it, let it build it, and get an LDraw LEGO© model.
What you get when the building process finishes:
Tools used by agents in order to find suitable parts and example models take advantage of jev-rerank (I'm also the author). This is a semantic search tool with re-ranking backed by TypeSafe 's Jev System One AI model.
Run ldraw-nova as a web app, with Docker. You need Git and Docker .
This web app will run dockerized, and to build the Docker image, two sibling repos are required:
1. Clone both repos side by side, at the same tag , so they work together:
git clone --branch v0.6.0 https://github.com/anteloc/ldraw-nova.git git clone --branch v0.6.0 https://github.com/anteloc/ldraw-nova-docker.git 2. Build the Docker image. The first build takes a while and needs about 5 GB of disk space:
cd ldraw-nova-docker docker compose build 3. Start the app:
