Qwen3-0.6B

the letter n opening a word

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 fires on the letter 'n' when it starts a word piece, often in Sundanese, Irish or other less common languages, and in words like 'navel' or 'nitrates'. Turning it up made the text shift to phrases like 'front door', and turning it down made it repeat 'living'. Neither change clearly relates to the letter.

Written by Claude from this neuron's activations and steering outputs. Confidence: medium. 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.
