LegoGPT creates Lego designs using AI and text inputs — tool now available for free to the public

A research team from Carnegie Mellon University built an AI model called LegoGPT that outputs valid LEGO designs from text inputs. According to the team’s research paper that’s posted on GitHub, they trained “an autoregressive large language model to predict the next brick to add via next-token prediction,” but the key takeway is that the AI LLM creates LEGO designs from scratch.

The AI was trained on a dataset with more than 47,000 LEGO structures that build over 28,000 unique 3D…
