Qwen3-0.6B

full stop ending an encyclopedia-style opening sentence

A neuron in layer 16 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 full stop at the end of a introductory sentence that defines a topic, such as 'a bond is one of the most prevalent securities.' The activations here are small compared with the others. Turning it up gave unrelated, wandering text.

Written by Claude from this neuron's activations and steering outputs. Confidence: low. Think it is wrong? Flag it (opens a prefilled issue on GitHub).
