Qwen3-0.6B

end-of-text token after a web page

A neuron in layer 6 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 strongly on the hidden "end of document" marker that appears where one web page stops and another starts. It is pushed slightly negative on the word "estrogen". Steering gave off-topic text, so the link to what the model writes is unclear.

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).
