Qwen3-0.6B

middle pieces of split words

A neuron in layer 0 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 a piece of a longer word that has been chopped into parts, such as the 'y' in 'privy' or 'electromyography'. It goes quiet or negative on endings like '-al' in 'non-governmental'. Turning it up did not produce a clear theme in the text.

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