Transformer Explainer Runs GPT-2 in Your Browser, Visualizing Every Layer
techNmak · x · 2026-10-10
Transformer Explainer is an interactive teaching tool that runs a GPT-2 model (124M params) directly in the browser. Type a sentence and follow the full pipeline: tokenization → embeddings → Q/K/V → attention → MLP → logits → next-token probabilities.
- Inspect attention maps and intermediate values.
- Tune temperature, top-k and top-p to see how generation changes.
- Ideal if Transformers still feel like boxes connected by arrows to you.
