Qwen3-0.6B

numeric ranges, second number

A neuron in layer 18 of Qwen3-0.6B. Its strongest snippets are fairly consistent: several of them peak on the same token. It is featured, so it has steering outputs.

What this neuron does

This neuron fires on the spot right before the second number in a range, such as 'ages 13 and [15]' or 'zones 4 to 10'. It turns off, sort of, on the bracket after a measurement like '50 miles (80 km)'. Turning it up made the text drift into unrelated phrasing.

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).

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.
