Qwen3-0.6B

opening bracket before an acronym

A neuron in layer 19 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 full organisation or term name, just before its short form, such as 'Centers for Disease Control and Prevention (CDC)'. It goes strongly negative on letters inside an acronym, and steering did not show a clear link to this.

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).
