Tool visualizes safetensors and quantization levels

Tools OpenSource

TL;DR: A developer released two tools for exploring safetensors file structures and verifying quantization, aiding model debugging.

Summary: A Reddit user created model_explorer.py and an unnamed second tool to visualize the block structure of safetensors files and check quantization (e.g., nvfp4). The tools parse model files into a tree view, showing layer sizes and weight tensors.

Why it matters: For AI builders working with compressed models, these tools simplify inspecting model architectures and confirming quantization precision. Try them to debug converted models or validate FP4/FP8 formats in ComfyUI workflows.
