An examiner is going to ask what testing you did on the AI.
Right now there is almost nowhere to get it.

We are an independent testing lab. We measure how often the language model your institution hosts makes things up, using your own question types, and hand you a signed, dated report for the model-risk file.

FIXED PRICE · FIVE BUSINESS DAYS · NO MEETINGS, EVERYTHING IN WRITING · NO CUSTOMER DATA
The regulatory moment

SR 26-2 leaves generative AI out of scope.

Nothing in the revised guidance requires an independent measurement. Examiners apply the same model-risk principles by analogy, and banks would rather have their own testing evidence in the file.

The instrument reads the model's internal signals while it writes an answer, rather than grading the answer afterward. Point it at the question types your staff actually use, on a model you host or designate, and it maps where the model fabricates and how often. Every flagged answer stays in the findings file so your own people can check it. Detection performance so far: 0.852 AUC on models it has never seen, fabricated-entity discrimination, length-controlled, leave-one-model-out. Method paper DOI: 10.5281/zenodo.21365654.

What it needs from you

No customer or member data, and nothing installed.

It never touches customer or member data. It needs a sample of your real question types and a model endpoint you designate: a self-hosted open-weight model, a vLLM-class private-cloud deployment, or a fine-tune your institution controls. Private Azure OpenAI exposes probabilities on output tokens only, which isn't enough for the instrument to read.

The first engagement gives you the baseline. Quarterly re-measurement after that builds the trend record your governance file points to as models change.

Terms

What an engagement costs.

The LLM Validation Report is $9,500. Continuous Assurance is $6,500 per quarter for one model. The pre-deployment Model Selection Study is $4,500 for two candidates, up to $7,500 for four. Full terms are on the pricing page. No work begins without a signed engagement letter, and no fee is ever success-based.

Straight answers

Questions bank risk teams ask first

Does SR 26-2 require this measurement?
No. The revised guidance leaves generative AI out of scope. Examiners apply the same model-risk principles to language-model tools by analogy, and it is easier to answer them with measured evidence in the file.
What does the test need access to?
A sample of your question types and a model endpoint you designate. That is the whole list, and everything you share is held confidential under a written agreement before any work begins.
We only use vendor-embedded AI. Is this for us?
Probably not yet. If your only AI is embedded in vendor software and the vendor attests to it, there is nothing of yours to measure.
What about confidential supervisory information?
We never ask for or accept examination materials or supervisory correspondence. The engagement is built so it doesn't come near CSI.
