Qwen3-0.6B

'up' in 'up to' limits

A neuron in layer 23 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 'up' in the phrase 'up to', as in 'for up to eight hours' or 'up to three astronauts'. Turning it up made the model produce 'up to zero' and 'to zero' loops.

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

Steering

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.
