'a' right after 'played' or 'play'

What this neuron does

This neuron fires on the word 'a' in phrases like 'played a key role' or 'plays a crucial part', right before the word that describes the role. Turning it down made the writing repeat 'a' and 'other' in a loop, but turning it up gave text that did not clearly stay on the topic of roles. Only the trigger is clear here.

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.

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.

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.
