> Visualize any Hugging Face model architecture as an interactive graph by pasting a model URL or repo name — no installation or configuration required.

hfviewer is a free web tool that lets you instantly visualize the architecture of any Hugging Face model as an interactive graph. Paste a Hugging Face model URL or repo name and get a clear, zoomable graph of the model's structure in your browser — no local setup, no config files, no notebook required. It is built by Embedl AB as a contribution to the Hugging Face community, and supports a wide range of transformer architectures including LLMs, vision models, multimodal models, and speech models.

- **Instant model visualization**: *Paste a Hugging Face URL or repo ID (e.g., `Qwen/Qwen3.5-4B`) and the graph opens directly in the browser.*
- **URL magic**: *Replace `huggingface.co` with `hfviewer.com` in any model URL to jump straight to the visualization.*
- **Granularity levels**: *Switch between high-level architecture overview and detailed substructure views to inspect specific blocks and paths.*
- **Family compare pages**: *Compare multiple related models (e.g., the Gemma 4 family) side by side with synchronized pan, zoom, and granularity controls.*
- **Embed in model cards**: *Press the Embed button to get embeddable code for use in Hugging Face model cards.*
- **Interactive blog format**: *Family pages link graph nodes to editorial explanations, enabling a graph-to-text and text-to-graph reading loop.*
- **Broad model support**: *Works with decoder-only LLMs, encoder-decoder models, vision transformers, CLIP dual encoders, pose detection models, speech recognition models, and MoE architectures.*
- **No installation needed**: *Fully browser-based; the first request may take a few minutes while the server analyzes the model and generates the graph.*
