Shows Hugging Face model architecture as a graph: layers, repeated blocks, branches and the overall data flow. It is useful when a learner has read a model card and wants to understand the internal structure.
How to use it
Open the resource, paste a Hugging Face URL or repo id such as `gpt2`, and inspect the graph from overview to detail. For quick comparison, start with the popular models on the home page.
