Qwen3-0.6B

'and' between stacked superlatives

A neuron in layer 8 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 word 'and' when it joins two describing words, like 'the oldest and most organized' or 'the newest and best'. It is quiet on 'as well as', which is the opposite pattern. Turning it up did not clearly change the model's writing.

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).
