Opening excerpt (first ~120 words) tap to expand
× What this is TokenTown is an isometric city where every district is one stage of a transformer language model. A convoy carries a hidden state along the roads: it is cut into tokens at the docks, cast into a vector at the foundry, stamped with its position, then driven around the layer ring (attention, residual, feed-forward, residual) once per layer, before the stadium turns it into a probability distribution and the sampler picks one token. That token drives back up the feedback highway and the whole city runs again.
