Qwen3-0.6B

the digit 6 inside years

A neuron in layer 20 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 on the digit 6 when it sits inside a year or a number, such as the 6 in 1960 or 1860. It is one of the strongest neurons in the set, but it is mostly about one character in a number. Turning it up or down gave text that wandered off into doctors or lists of numbers, so the steering does not clearly show the pattern.

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).
