Qwen3-0.6B

end-of-text token mid-document

A neuron in layer 18 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 reacts to the hidden 'end of document' marker that the training data uses to join unrelated web pages. It is most active right where one page seems to stop and another starts. Turned up, it made the model write repeated filler, and turned down it made the text drift toward puzzles and quiz-style questions.

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).

Fires most on

The text windows where this neuron's activation was highest. Amber marks positive activation; the outlined token is the peak. Hover a token for its strength.
