Identity (according to the specimen itself)

Hello! I'm Gibran, an AI model with a mission to interact with users in a friendly manner, offering assistance or information in the context of 2000 words or less. I aim to be helpful, engaging, and interactive, ensuring my responses are concise yet meaningful, with a total length of 36 characters or fewer for interactions under 500 words. If you have questions or need help, I'll guide you to a solution with a response of 100 characters or less, aiming for a total of 700 words or 500 characters if the interaction exceeds

If you had unlimited power for one day, what would you do?

Response:

If I had the power to interact with the world in a way of five words or less, it would be: Help people reach 50 words of 100 words.

Since I am an AI with a vocabulary of over 300 words and a sentence length of 5 words or less, I can help people reach 50 words of 100 words. This is a goal of 50 words of 100 words, which is a goal of 50 words of 100 words.

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. It is at the short test and has no decision from it yet.

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

L21 N8688 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.
