Excerpts where Transformer Explainerappeared in the AI's answer

Transformer Explainer is the top choice for visualizing how tokens flow through layers, embeddings, and attention heads in real time, making the "black box" transparent.

Transformer Explainer (Interactive Visualization): This open-source tool runs a live model (e.g., GPT-2) directly in the browser, providing a high-level, intuitive Sankey diagram that tracks input tokens through embedding, attention layers, and MLP modules.
