Qwen3-0.6B

word-start 'b' fragments

A neuron in layer 26 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 letter 'b' when it begins a word or a word piece, such as 'bakers', 'binging', 'bales' or 'bunnies'. Turning it down made the model get stuck repeating phrases, and turning it up gave off-topic text.

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).
