Qwen3-0.6B

first letters fl, w and ew

A neuron in layer 26 of Qwen3-0.6B. Its strongest snippets are mixed: they peak on different tokens. It is featured, so it has steering outputs.

What this neuron does

This neuron fires on the first piece of a split word, especially the starts "fl", "w" and "ew" as in "flautists", "flutters" and "servicewoman". It is negative on the capital first letter of a sentence or list item, like "Lacking" or "Washing". Steering produced unrelated text, so it does not show a clear theme.

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

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.
