Qwen3-0.6B

end of a document boundary

A neuron in layer 13 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 switches on at the invisible marker that ends one web page or document and starts an unrelated one. Its strongest moments are the places where one text stops and a different one begins. Turning it up made the model's writing drift into rambling, unrelated sentences rather than any clear theme.

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).

Activation histogram

How often this neuron fires at each strength. Almost always it does close to nothing (the tall bars in the middle); the snippets above are the rare moments it fired hard, amber for positive and blue for negative.
