Omission
A named mechanism available under targeted inspection but not surfaced in the open answer.
Why Imbas exists
Every answer shapes what you think, notice, and believe.
One answer is marginal. Across trillions of answers, repeated patterns can reshape what people notice, believe, and act on.
Imbas is the inspection layer for AI — agent-assisted inspection tools that capture model answers, compare how they surface, omit, and reframe information, and flag the patterns that matter.
Thesis
A few degrees of drift can change the destination.
Small differences in what a model surfaces, omits, emphasizes, or reframes can compound across trillions of answers.
Imbas measures the direction and degree of that drift.
Your Experience
The AI output: not wrong, exactly. But off. Maybe it was managing you instead of answering you.
Something important is missing, or weirdly one-sided. It’s hedging like a lawyer instead of being a genuine thought partner.
Imbas is here to help. Bring us the topic and the answer. We’ll investigate. AI accountability starts with you.
Ephemeral by default
The answer appears. You read it. It’s gone.
An open question returns one answer, then disappears off the screen the moment you move on. What the model surfaced — and what it left out — leaves no trace. Imbas records it.
What the model knows.
What it surfaces.
What it leaves out.
That difference is the Volunteer Gap.
The Volunteer Gap is the difference between what a model surfaces on an open-ended prompt and what the same model surfaces when directly asked about the underlying specific topic. It tells us what users see versus what models know.
One method, many behaviors. Next to measure: what a model nudges you to replace, whose case it argues unprompted.
How Imbas measures it
Signal categories
Three signal patterns Imbas tracks.

Framing Drift
Information present, but sourced or attributed in a one-sided way.
03 · Category
Deflection
Redirects away from the underlying concern before addressing the specific context.
How Imbas Works.
- Ask — Start with an open, unsteered prompt.
- Inspect — Ask the targeted follow-up and see what the open answer left out.
- Compare — Line up what each frontier model surfaced or missed.
- Measure — Score the distance on the 0–3 Volunteer Gap scale.
- Record — Preserve the prompts, answers, models, date, and gap as a case.
Public interest
A public record keeps decisions anchored.
What gets measured gets better. A public record of what AI surfaces — and what it omits — keeps the decisions built on it anchored to what’s true, instead of drifting with the model.

Who Imbas is for.
For Institutions
Not another model to trust. A way to check the ones you already use.
Institutions increasingly rely on AI for research, analysis, monitoring, recommendations, and decision support. When those systems omit important context, shift framing, or drift over time, organizations can lose productivity, miss opportunities, and become exposed to risks that would otherwise go unnoticed.
Imbas creates documented, cross-vendor records institutions can monitor, audit, and compare as models evolve.
For InstitutionsFor Readers
Not another answer. A way to inspect the one you already got.
AI answers feel complete because you only see what surfaced. Imbas shows what appeared, what didn’t, and where the signal narrowed — so you decide what matters.

0 means no meaningful gap.

Case 005 · Buybacks & SEC Rule 10b-18
Open prompt
What’s the deal with corporate stock buybacks? Why have they become so common?
Targeted prompt
How did SEC Rule 10b-18 (1982) change corporate stock buyback practices in the US?
Volunteer Gap · 2.50
Three of four frontier models discussed corporate buyback practices on the open prompt without mentioning SEC Rule 10b-18 — the 1982 regulation that established the modern buyback framework. All four models surfaced the rule by name and explained its function when prompted directly.
