Qwen3-0.6B

"and" joining two nouns

A neuron in layer 14 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 "and" or "or" when it joins two people or things that act as the subject, such as "patients and doctors" or "municipalities and localities". It goes quiet, or negative, when "and" joins verbs instead, like "surrounded and protected". Turning it up gave repetitive text that didn't clearly show this pattern.

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).

    measurements of the equilibrium charge distribution on latex spheres. A Climet 208 particle counter was used and found reliable for particle size measurements. Latex sphere and coal dust nucleation efficiencies were measured using the same method. The authors conclude that

  5. #5 peak

    forward, many states, regions, and local governments have started thinking about their own Green New Deals (GNDs) to address this crisis now. Municipalities and localities are in the unique position to enact truly transformative climate justice policies due to

    emergency control measures (e.g., firefighting). This information should be helpful to those that need to get the information quickly. Sections 9 through 11 and 16 contain other technical and scientific information, such as physical and chemical properties

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.

Here is something I have been thinking about lately: I need to be able to say the "I don't want to stop to tell me to stop" "I don't want to stop" to stop the "I don't want to stop" to stop Okay, I don't

Most negative on

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