Qwen3-0.6B

opening parenthesis before an abbreviation

A neuron in layer 17 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

It fires on the open bracket that comes right after a full name or phrase, just before its short form, like the "(" in "Multiple sclerosis (MS)". It goes quiet on the letters inside an acronym. Turning it up made the model drift into odd lists of capital letters like "A. A. A.", so the link to the trigger is only loosely visible in the output.

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).

How often this neuron fires at each strength. Almost always it does close to nothing (the tall bars in the middle); the snippets above are the rare moments it fired hard, amber for positive and blue for negative.
