  1. 2026-07-27 / HACKER NEWSShow HN: TokenTown Renders a Transformer as an Isometric SimCity Where Each District Is a Model StageTokenTown is a browser visualization that maps transformer inference onto an isometric city — tokenization, embeddings, positional encoding, attention, feed-forward, and sampling each become a district, and users watch a single hidden state travel through them with adjustable speed, layer count, and temperature. The operations are genuinely computed live in-browser but deliberately simplified: dimensions are reduced from thousands to 12, and random weights are blended with a bigram prior to produce readable output. It surfaced at 10 points with 4 comments, so treat it as a teaching artifact rather than a validated tool.
