Qwen3-0.6B

the 'S' in 'U.S.'

A neuron in layer 0 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 weakly on the 'S' in the abbreviation 'U.S.', as in 'U.S. Food and Drug Administration'. The effect is small, and turning it up gave off-topic text, so the steering does not show much.

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).
