'is' after a topic noun phrase

What this neuron does

This neuron lights up on the word 'is' (or 'are') right after a phrase that names a topic, like 'One of the most common uses of this calculation is' or 'The exception to this is'. It is waiting for the sentence's main point to come next. Turning it up made the model's writing wander into generic, repetitive phrases about 'the most important thing'.

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.

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.
