Qwen3-0.6B

numbers after dates and figures

A neuron in layer 12 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 spot just before a number in a date or a quantity, such as "on 13 November" or "chills or fever of 100.4". The examples are mixed, so the pattern is fuzzy. Turning it up gave text that did not clearly change.

Written by Claude from this neuron's activations and steering outputs. Confidence: low. 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.
