Qwen3-0.6B

word fragments inside split words

A neuron in layer 7 of Qwen3-0.6B. Its strongest snippets are mixed: they peak on different tokens. It is featured, so it has steering outputs.

What this neuron does

This neuron fires on the middle or end piece of a word that the model splits into several pieces, such as 'incision', 'peregrine', 'chemist' or 'breadboard'. Turning it up made the output loop on numbers and odd phrases, which does not clearly connect to that 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).

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.

  1. #1 peak

    uses a laparoscope, a viewing instrument with a light, to see your uterus and pelvis. The laparoscopy is inserted through a small incision in your belly. This procedure is generally performed under general anesthesia in a hospital.⏎

  2. #2 peak

    amarins are about 6-12 inches long, with tail being almost 16 inches! Their fur is dark brown and they have white tuft of hair on the top of their heads. Cotton Top Tamarins live for

  3. #3 peak

    face covering should cover the nose and mouth and should fit with no gaps.⏎4. Secure the face covering to the face with straps, tie in the back or loop over ears. Avoid touching the front of the face covering.⏎5. Try not

  4. #4 peak

    Arfwedson, a Swedish chemist.⏎It’s silvery white, soft and can store more energy than traditional metals

  5. #5 peak

    falcon nest.⏎The birds are on Forest Service land accessed through Iron Horse Trail State Park and near Olallie State Park. The peregrine is designated a sensitive species and requires the Forest Service to protect its breeding habitat.⏎

  6. #6 peak

    signed "Gutzon Borglum 1929 (illegible) AKUNST FDY NYC". The back of the base is inscribed: "NORTH CAROLINA".⏎A 1913 North Carolina

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: the main problem is at the center of the main length of the segment, so If is it otherwise, a check would be too big. If is the data rectangle of the element, height of 22, width height of 1

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

    much insulin or diabetes medication. A lot of physical activity can also cause low blood sugar, even hours later. In severe cases, low blood sugar can lead to seizures or passing out.⏎Everyone’s symptoms are different. Your child may feel dizzy,

  3. #3 peak

    just may be that rheumatoid arthritis sufferers will benefit from early prediction in the future. The 2018 annual conference of the European League Against Rheumatism (EULAR) approached this topic with two different studies that looked into molecular

Activation histogram

How often this neuron fires at each strength. Almost always it does close to nothing (the tall bars in the middle); the snippets above are the rare moments it fired hard, amber for positive and blue for negative.
