Qwen3-0.6B

the digit zero inside numbers and times

A neuron in layer 11 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

Fires on the digit 0 inside a number, especially in clock times like "12:00" or "8:00 am" and in codes like "6.00". Turning it up made the model ramble about temperatures and repeat itself, which does not match the trigger.

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.
