Describe a rainy city street at night in the style of a 1940s noir detective novel. One paragraph.

Response:

The rain hammered down on the cobblestones,
A neon sign flickered in the dark,
A shadowy figure walked past the window,
A detective's mind wandered through the night.

The city hummed with a rhythm,
A streetlight glowed in the gloom,
A detective's eyes watched the scene,
A noir's soul slept in the dream.

The rain fell hard on the pavement,
A neon light shone in the dark,
A shadowy street hummed in the night,
A detective's heart beat in the gloom.

The city slept deep in the dream,
A streetlight dimmed in the dark,
A detective's mind rested in the night,
A noir's soul woke in the dream.

What does it mean when a central bank raises interest rates, and why would it do that?

Response:

When a central bank raises interest rates, it means the cost of borrowing money increases. This is because the price of loans goes up, making it more expensive to borrow funds.

Technical details

Quick scan: measure prediction shifts on fixed reference text. Short test: generate replies to a small set of prompts. Longer test: extend to a larger set. Full test: run the full prompt suite. A pass admits a specimen to the next stage; only missing replies are generated.

Funnel · what each test made of this specimen

Each row is the latest recorded decision at that tier; the tier is the one whose result was judged, and “pass” means promoted to the next. This specimen stopped after the short test: it stays on file with that test's results, and its replies above are everything it was asked to generate.

Quick scan · band	t0-promote-v3	pass	KL 1.38 · agreement 0.54	1 <= KL <= 2.5, 0.5 <= agreement <= 0.65; random within the band, round-robin across layers

Quick scan · prediction measurements

Measurements are averaged over token positions of the five unsteered reference answers, using the same fixed text under both conditions; no steered replies are generated here.

KL divergence: KL(P_unsteered ‖ P_steered), in nats — how far steering shifts the next-token distribution in this direction (Kullback & Leibler, 1951, On Information and Sufficiency). Unsteered ≈ 0.001.
Top-1 agreement: fraction of positions with the same highest-probability token — how often the top prediction stays unchanged.
ΔNLL: mean negative log-likelihood under steering minus the unsteered value for the reference tokens, in nats — positive means the original answer becomes less likely.
Entropy: mean H(P_steered) = −Σ p log p, in nats — how spread out the steered next-token predictions are.

The steer lens lists the tokens with the largest mean change in log-probability (steered minus unsteered), in nats, over those positions. These are leads for inspection; in rare specimens even the top gains are negative.

Method · how to read this specimen

L2 N4406 down 1x

A specimen is a fixed steering configuration of Qwen3.5-4B: one MLP neuron or a pair, each with a signed dose. Unsteered is the control. L identifies the layer; N, the neuron.

Additive activation steering. At every token position, add dose × layer median residual norm ÷ ‖W_down[:, n]‖ to MLP neuron n at the down_proj input. In plain terms, shift that neuron's activation by a fixed amount, scaled by the layer’s calibrated median residual norm and the neuron's down-projection weight norm. Positive doses push up; negative doses push down. Dose is normalized intervention size, not a percentage or probability.

Cyan borders mark this specimen’s words. Flags record AI-judge checks with P(yes) > 0.5.

Label notes: names and descriptions are working labels. They do not establish a trait across prompts. Consult the replies before trusting the name.
