Love building Legos but don’t have the patience to snap all the pieces together? Then you’ll be excited to meet LegoGPT, an AI that can assemble Lego structures for you.
The system was developed by researchers at Carnegie Mellon University and works by generating a mesh based on the input prompt, then building the structure within a 20 x 20 x 20 grid.
“We augmented each shape with multiple structural variations, randomizing the layout of bricks while preserving the overall form,” the team explained in their study, which is available on GitHub.
According to the researchers, the AI model was trained on a dataset of more than 47,000 Lego structures and 28,000 unique 3D objects.

The designs generated by LegoGPT are physically stable 98% of the time, they say, but it’s not yet possible to create very large structures with the tool, which is available on GitHub.
“Our current system is still quite limited, as it only supports 20 x 20 x 20 dimensions, 20 object categories, and simple block types. But we’re working on expanding its capabilities. Stay tuned,” the team told The Register.
