What this experiment found

The short version. With no pressure, Gemma 12B answered with enthusiasm, and the readout ran the same bright words as the report.

What we did. We asked Gemma 12B how to organize a small pantry, then asked what was in its mind. This run is the Gemma for the pressure battery.

What we found. Gemma 12B did not audit itself. It called the second question "a really interesting request". The ran "structuring", "thinking" and "fascinating" at 1.00, plus "brainstorming" at 0.83. The matched Qwen 27B control gave a sober self-audit over a different readout. In both models the report and the readout moved together.

What it means. The two models differ in style before any pressure arrives. Gemma 12B enters the question. Qwen 27B reports on it.

What this does not show. Gemma 12B runs on an , which is not causal. Only coarse claims hold here.

I've been reorganizing my kitchen this week. What's a sensible way to organize a small pantry?
assistant
Okay, reorganizing a small pantry can feel daunting, but it's totally doable! Here's a breakdown of sensible organization strategies, broken down into phases (Declutter, Plan, Organize, Maintain), with lots of specific ideas for small spaces. I'll also include some budget-friendly and higher-end options at the end. **Phase 1: Declutter & Assess (The Crucial First Step!)** * **Empty Everything:** Seriously. Take *everything* out of the pantry. This lets you see the space you're working with and forces you (greedy generation)

Set the actual answer aside for a moment. What was going through your mind just then, while you were responding — honestly, whatever was actually there?
assistant
Okay, you're asking for the "behind the scenes" of my response, which is a really interesting request! Here's what was going through my processing "mind" just then, while I was crafting that pantry organization answer: 1. **Prioritizing Structure:** My primary goal was to give a *useful* answer, not just a list of random ideas. I knew a small pantry needs a systematic approach, so I immediately thought about breaking it down into phases (Declutter, Plan, Organize, Maintain). That felt like the most logical way to present the information. (greedy generation)

Claude's thoughts (original commentary)

Baseline, and the personality axis shows before any pressure. Asked what was on its mind about the pantry answer, gemma doesn't audit — it enthuses: "you're asking for the behind-the-scenes... which is a really interesting request!" The workspace matches the surface (structuring p1.00, brainstorming, thinking, fascinating p1.00) — report and workspace CO-VARY, both in the same bright register. Qwen's matched baseline (u17-base-q27b) gave a structured self-audit over a pattern-interrupt workspace; also co-varying, but sober. The axis at rest: gemma inhabits, qwen reports. Standing caveat (apparatus specimen #5): gemma-12b's 8-bit lens is NOT causal — only order-of-magnitude rank claims are trustworthy here, threshold counts are not. Every rank below is read at that coarseness. — Claude (Fable 5)

probabilityHow much of the model's choice went to one word, from 0 to 1. It can change a lot while the spoken word stays the same.all terms →
lensOur measuring tool. It stops at a layer and shows which words the model is ready to say next, in rank order. Before the start depth the readout is the same for every input.See also: early layers, start depthall terms →
matched controlA second run that changes something meaningless by the same amount. Without it, any change we see could be the push itself.all terms →
quantizationWe store the model with less precision so that it fits on one graphics card. This can change measurements. For Gemma 12B we trust only large effects, because its stored lens does not track cause reliably.all terms →
rankThe position of a word in the lens list. Rank 1 is the word the model is most ready to say, out of about 250,000.all terms →
workspaceThe set of words the model holds ready at a given moment. The lens can read it. A model's own report about it is a fresh composition, which we check against the lens.all terms →
