Qwen3-0.6B

'an' in definitions and descriptions

A neuron in layer 16 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 'an' in definition-style sentences, such as 'is an intolerance', 'is an annual publication' or 'the meaning of an acronym'. The other side of the scale is weak and not very meaningful. Steering produced unrelated writing, so the test does not confirm the pattern.

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).
