A research project in two phases

What does a language model know, and where inside it does that knowledge appear?

First we compared what models choose on chess positions. Now we look inside one model, Qwen3-8B, to see how an answer forms layer by layer.

Phase 1 · Chess
Done

Outside the model

Given one chess position, what move does a statistical model expect, what does a language model prefer, and what would a human play?

Illustration. One position, three models, three suggested moves.

What we found: adding a model of human play improved discrimination of controlled move substitutions, from 0.820 to 0.873 ROC-AUC on held-out source games. This is a synthetic assistance task; the language model's held-out evaluation is still pending.

Inside the model

When a language model recalls a text it has memorized, where inside the model does the right next word appear?

1st choicefirst layerlast layer
Recorded on Qwen3-8B-Base, 316 words of the Gettysburg Address: the median rank of the correct next word goes from 62,391 at the first layer to 1 at the last. Earlier layers are read through a diagnostic projection.

What we see so far: on a memorized text, the correct next word usually becomes the model's top choice only in the last few layers.

Where to start

  1. 1The 5-minute demo →How Qwen works inside, one real measurement, and the question for the next step.
  2. 2The proposed next experiment →Why two model sizes with the same recall may still differ inside, and how to test it.
  3. 3The Recall Microscope →Follow the correct next word through every layer of the model, position by position.
