Qwen3-0.6B

the word 'simple' and 'Santa' in Santa Barbara

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

What this neuron does

This neuron mostly lights up on the word 'Santa' in 'University of California, Santa Barbara' and on pieces of words meaning 'simple' or 'simplify'. When it was turned up, the model started repeating the word 'simple' again and again.

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.
