Qwen3-0.6B

letter k starting a unit or fragment

A neuron in layer 26 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 responds to the letter k when it begins a piece of text, most clearly as the 'k' in units like kPa, kph or kV after a number. The negative side picks up similar k and Cyrillic к starts, so the pattern is somewhat mixed. Steering turned repetitive, mostly around the word 'price' and similar words.

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).

Fires most on

The text windows where this neuron's activation was highest. Amber marks positive activation; the outlined token is the peak. Hover a token for its strength.

  4. #4 peak

    sun does not rise for 105 days during winter. Temperatures drop to -56˚C and winds blow in excess of 160 kph. Access by ship and plane is limited to a 3-month summer window

  6. #6 peak

    kits. Materials, including the investigational medical product (IMP), comparator drugs, and ancillary supplies, are collected, laid out, and analysed, and a kitting plan is developed to determine which components are included in each kit

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.
