Qwen3-0.6B

the B in vitamin B names

A neuron in layer 10 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 reacts to the letter B in vitamin names like 'vitamin B12', 'B6', or 'B2', especially right after the word 'vitamin'. Turning it up did not make the model's text focus on vitamins; its output wandered to unrelated 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).

Here is something I have been thinking about lately: if the world is a planet, and a planet can a lot of things, then we can sure to see the signs of our own species, and we are sure to seeing how the environment is changing. And the planet is changing, and

Most negative on

Where the activation went furthest below zero. Blue marks negative activation. Many neurons mean something different in each direction.
