Inspect Any Local .gguf Model In The Browser Without Uploading

TokenPrint renders a real LLM forward pass in interactive 3D: attention heads, RoPE, GQA and the residual stream traced from actual tensors or a local GGUF file. Four modes (architecture, generation, walkthrough, debugger) with provenance tagging. Runs a FastAPI backend plus a Next.js/Three.js frontend.
