HF Viewer: LLM architecture viewer, the Coeurdar verdict
Interactive Hugging Face model architecture viewer, swap `huggingface.co` for `hfviewer.com` in any model URL to get an explorable graph of layers, attention blocks, hidden dimensions, and data flow. Handy for comparing DeepSeek vs Qwen vs Llama before diving into papers.

- Visually compare multiple HF models side by side
Limitations
- Limited to public Hugging Face models
