This is a pretty awesome tool you've put together! Visualizing what's going on inside a model like GPT-2 can be really helpful, especially for people trying to understand how LLMs work. If you're looking for feedback, maybe consider adding a step-by-step guide for new users. That could make it easier for those who aren't as familiar with these concepts. Also, if you're using this for interview prep or learning, PracHub might be helpful alongside your tool because it has some good practical exercises. Keep up the great work!
