Transformer Explainer: Interactive Visual Walkthrough of GPT-2 Internals
jackedAJ · x · 2026-09-24
Transformer Explainer from Georgia Tech's Polo Club is an in-browser interactive visualization that runs a real 124M-parameter GPT-2 (small) model, letting users tinker with embeddings, self-attention, and temperature/top-k/top-p sampling step by step — a hands-on way to actually learn how transformers work.
