Qwen3-0.6B

the letter C in vitamin C

A neuron in layer 4 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 strongly on the letter C when it comes right after the word vitamin, as in vitamin C. Turning it up made the text ramble about repeated phrases and numbers rather than about vitamins.

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).
