Qwen3-0.6B

"D" in vitamin D

A neuron in layer 6 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 letter D when it follows the word "vitamin", as in "vitamin D" for health articles. Turning it up did not produce a clear theme, and the negative cases are mostly about database and code 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).
