Qwen3-0.6B

the word 'form' in 'formative'

A neuron in layer 3 of Qwen3-0.6B. Its strongest snippets are fairly consistent: several of them peak on the same token. It is featured, so it has steering outputs.

What this neuron does

This neuron lights up on the 'ative' part of the word 'formative', mostly in education contexts about assessment and learning. Turning it up made the writing wander without a clear topic, so the link to the word is the main clue.

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).
