Qwen3-0.6B

'a' before 'few' or 'couple'

A neuron in layer 25 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 lights up on the word 'a' when it is followed by a small amount like 'a few', 'a couple' or 'a moment'. Turning it down made the model repeat 'a' endlessly, and turning it up made the text wander off topic.

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.

    to facilitate the shedding of the uterine lining. Uterine polyps can vary in size, with the smallest being only a few millimeters wide. The growths mostly occur in women who are going through

  2. #2 peak

    a thorough scan on your system. Before you do that, though, take a few extra precautions.⏎Is your computer part of a network?⏎If so, you

  3. #3 peak

    area of electronics. A myriad of modern items ranging from cell phones to digital watches, elevators to washing machines contain microprocessors. It is incredible that, just a few decades ago, the microprocessor did not even exist, and yet today it

  4. #4 peak

    and choose your view.⏎When the system has enough activity and grade data to display, you'll receive an alert in your activity stream. You might need to wait a couple of days as a certain level of student engagement is needed to trigger this alert

  5. #5 peak

    're making pancakes. You pour 100 grams of flour, a little less than a cup, into the bowl. You add 1 gram, about a quarter of a teaspoon, of salt. After all the other ingredients, you mix

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.

Most negative on

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

  1. #1 peak

    example, try walking for 15 minutes at an average pace. If you feel this is comfortable, you can increase your time or intensity (only adjust one at a time to ensure that your body is ready for the challenge). Alternately,

  2. #2 peak

    around Europe, since France was the trend setter then. The new invention was most often called "steps" because you had to step on them, usually one foot at a time, but a set of steps was named after their inventor, Stairs

  3. #3 peak

    by testing them for anti-HIV activity. In test tube experiments called “assays,” new compounds are added one at a time to cell cultures or actual human cells grown in a laboratory. The goal

  4. #4 peak

    plants grow best when you develop an affinity for them, and this comes from close observation of the plants plus a large application of common sense. Just take one step at a time. Master the fundamentals before you succumb to the excitement of special techniques
