Qwen3-0.6B

"the" before a topic noun

A neuron in layer 20 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 "the" in explanatory sentences about a subject, such as "the disease", "the tool" or "the practice", right where a topic noun is about to come. Turning it up made the model produce loops of "this", and turning it down made it repeat "the world".

Written by Claude from this neuron's activations and steering outputs. Confidence: medium. Think it is wrong? Flag it (opens an email to the maker with the neuron already filled in).
