Qwen3-0.6B

comma closing an introductory phrase

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 the comma that ends a short opening phrase, such as 'When hunger strikes,' or 'Despite the snow cover,', just before the main part of the sentence starts. When it was turned up, the model's replies did not show this 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).
