Qwen3-0.6B

the word 'age' in age groups

A neuron in layer 23 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 word 'age' when it means a group of people, as in 'this age group' or 'older age'. Turning it up made the model repeat the word 'group' over and over, which matches what the neuron pushes toward.

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