Qwen3-0.6B

the letter f starting fume or fountain

A neuron in layer 27 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 responds to the letter f at the start of a word piece, most often in fume, fountain, fumes and farsighted. Negative values appear on capital F in Frontera. Turning it up made the model repeat phrases like 'meeting meeting', so the steering shows no clear link to the f pattern.

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).
