Qwen3-0.6B

digits inside years like 19xx

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

This neuron lights up on the digits inside years, especially the 9 in dates like 1997 or 1909. It goes strongly negative on large round numbers and ancient dates such as 15000 BC or 10,000 years ago. Turning it up made the model's text drift into unrelated rambling about the weather, the news and everyday topics.

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).
