'B' in vitamin names

What this neuron does

This neuron fires on the letter 'B' when it follows the word 'vitamin', as in 'vitamin B12' or 'vitamin B1'. The strongest hits come from nutrition text. Its negative side appears on place-name fragments like 'Otago' and 'Copeland', which don't share the vitamin theme. Turning it up did not make the model talk about vitamins.

Steering

Push this neuron up or down while the model writes, and watch what changes. The outputs were generated ahead of time, so nothing runs in your browser.

Most negative on

Where the activation went furthest below zero. Blue marks negative activation. Many neurons mean something different in each direction.

Which neurons in earlier layers feed this one, and which later ones it feeds. Amber links excite, blue links suppress; longer bars are stronger.

Activation histogram

How often this neuron fires at each strength. Almost always it does close to nothing (the tall bars in the middle); the snippets above are the rare moments it fired hard, amber for positive and blue for negative.

Logit lens

The words this neuron nudges the model toward (amber) or away from (blue) when it fires. A hint, not a label: many neurons work through later layers instead.
