Qwen3-0.6B

capital P starting 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 responds to a capital P that begins a word or abbreviation, such as PNAS, PLOS, Prayer or Purgatory. It tends to go quiet or turn negative on lowercase p in the middle of words like pumas or penguins. Turning it up made the model repeat words like 'record' or 'external'.

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).
