Qwen3-0.6B

opening parenthesis after a name

A neuron in layer 24 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 an opening bracket that comes right after a name or term and introduces another name, a translation, or a brand, such as 'cetirizine (Zyrtec)'. Turning it up made the model's output break into run-together words with no spaces, so the steering tells us little about the pattern itself.

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).
