An interactive 3D visualization and walkthrough of a GPT-style LLM running inference, showing the network down to individual add and multiply operations. It renders the transformer topology used in GPT-2/GPT-3 and includes a working tiny example model from Karpathy's minGPT.

Use cases

• visualize how a GPT transformer works step by step
• learn LLM inference internals interactively
• understand attention and transformer architecture in 3D
• teach students how ChatGPT's underlying algorithm works
• explore a working GPT model down to individual operations

When to choose

• you want an intuitive, visual explanation of transformer inference
• you're teaching or learning how GPT-style networks compute
• you prefer interactive 3D walkthroughs over papers or blog posts

When to avoid

• you need a production LLM training or inference tool
• you want to visualize your own model's weights at scale (large weight downloads unsupported)
• you need a general-purpose neural network debugger
