Qwen3-0.6B

'only' in 'not only ... but also'

A neuron in layer 15 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

Fires on the word 'only' in the phrase 'not only ... but also'. Its strongest negative reactions come on the word after a number and unit, such as 'years old' or 'grams of'. Turning it up gave text that drifted into repetitive or unrelated sentences.

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).
