But a team from Carnegie Mellon University has created a smart AI model called LegoGPT. It can produce Lego designs from text alone. The team trained LegoGPT with a data set(数据集)called StableText2Lego. To create it, the team first let the AI read a text prompt(提示符) and then turned it into a ShapeNetCore mesh(网状物). Then this appeared in a voxel grid(体素网格) to set up the basic form. The form was changed, and only stable designs were kept. Finally, those left were on show from 24 different angles and ChatGPT's GPT-40 briefly described the final output. The data set has over 47,000 Lego structures. All kinds of 3D objects, such as tables, cars and guitars, have gone through the process. With the data set, LegoGPT can help people create new designs. It first turns the text into a Lego design. That design is then broken down into text tokens. Instructions are created to pair the structured Lego bricks with notes explaining the design, so that the AI will understand the relationship between the text prompt and the bricks. From there, LegoGPT predicts the next brick needed to build the design. It also checks if the structure works. If there's a problem, the AI will go back to a safe point and start again. This goes on until the design is over. LegoGPT is now free for everyone online.It can also be paired with other tools like image processing(图像处理)AI.For example,you can take a photo of your Lego bricks and let the AI suggest what you can build with them.
