Qwen3-0.6B

dash inside a number range

A neuron in layer 13 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 dash or hyphen that sits between two numbers, such as a time range (4pm-9pm), a pair of years (1338-1573) or a span of dates. When it was turned up, the model's replies drifted into unrelated, rambling text, so the steering does not show a clear effect.

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).
