Qwen3-0.6B

'the' after 'between' in age ranges

A neuron in layer 27 of Qwen3-0.6B. Its strongest snippets are very consistent: they mostly peak on the same token. It is featured, so it has steering outputs.

What this neuron does

This neuron lights up on the word 'the' when it comes right after 'between', as in 'between the ages of 15 and 24'. When it was turned up, the text started repeating the word 'age' over and over, and when turned down it produced ordinary unrelated text.

Written by Claude from this neuron's activations and steering outputs. Confidence: high. Think it is wrong? Flag it (opens a prefilled issue on GitHub).

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.
