Qwen3-0.6B

the spot just before a historical number

A neuron in layer 27 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 lights up on the spot right before a number, especially a year, a century, or a count like '13th' or '250 aircraft', so the model is ready for a figure to come next. It is strongest in history-style text. When it was turned up, the writing drifted into unrelated topics rather than more dates, and when turned down the text filled with zeros. Its negative side fires on digits in the middle of a number.

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).
