Qwen3-0.6B

'at' in time and occasion phrases

A neuron in layer 21 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 word 'at' when it follows a verb or adjective and comes before a time or situation, as in 'at night', 'at first', 'at any point'. Turned down, the model produced loops of 'from the', but turned up it did not show a clear theme.

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).

Push this neuron up or down while the model writes, and watch what changes. The outputs were generated ahead of time, so nothing runs in your browser.
