Query, Key, Value — the weighted pour
Ask a model how it makes sense of a word and the honest answer is: it goes shopping. Every word holds up a label advertising what it offers, with its content behind. When a word wants to know who did the sitting, it reads all the labels at once and pours itself a drink — a big glug from the best-fitting bottle, a thin trickle from the rest. What it walks away with is that blend. Attention is not a single choice but a mixture measured by fit.
A big pour from the best bottle, a splash from the rest.
