AI DATA & EVALUATION Human and model evaluation graded compared calibrated on record

Model outputs, graded against your rubric.

YPAI evaluates model outputs against your rubric, target population, languages, operational conditions and acceptance thresholds. Credentialed reviewers grade in the language the output was written in, a judge model is calibrated against them, and every verdict ships in the record your file needs.

Scope an evaluation brief

The claim points at the frame.

Every claim in a response is checked against the source the model was given. A claim the frame does not show fails on source use, whatever else the response gets right.

The set is built before the model sees it.

Items are written after the model's training cutoff, stratified by scenario, language, population and difficulty, then versioned and frozen. The same set runs again before every release.

A held-out item is graded on the page the day it is written and stays out of every training corpus. Its hash is in the manifest.

The judge is graded before it grades.

A judge model scores the same items the reviewers scored. Its agreement with the adjudicated human verdict is reported as Cohen's Kappa against the floor, and its position bias is measured by grading each pair in both orders. It grades alone only when both hold.

FAQ

Procurement FAQ

When does a judge model grade on its own?

After calibration. The judge scores a held-out slice the reviewers already adjudicated, and its Cohen's Kappa against the human verdict is reported against the floor agreed for the task. Each pair is graded in both orders, and a verdict that flips is counted as position bias. Above the floor and consistent under the swap, the judge grades alone, with a human slice re-graded every run.

How many reviewers grade each item?

Two, with an adjudicator on disagreement, as the default. Subjective tasks such as tone or preference use three to five. Credentialed domain reviewers grade where the domain requires them, in 150+ languages.

What does the evaluation record contain?

Per item: the output, the verdict per criterion, the reviewer, the rubric version and the run id. Per run: the frozen set id, the agreement statistics, the judge calibration, the thresholds and the pass or fail per criterion. The trace of an agent run is delivered in the Inspect format.

How are agents evaluated?

On the trajectory and the end state. Every message, tool call and result is logged; the scorer checks the state of the sandboxed environment after the run; a reviewer reads the trajectories the scorer flags, at a share agreed per task.

Which safety taxonomy do you use?

The MLCommons AILuminate hazard taxonomy: twelve categories in three groups, physical, non-physical and contextual. Attack success rate and over-refusal rate are reported side by side, so a model that refuses everything is visible as such.

Do you certify the system?

YPAI evaluates. The provider runs the conformity assessment under Article 43, and a notified body where the Act requires one. The evaluation report enters the provider's Annex IV file as supplier evidence, named as such.

How does the set stay clean between releases?

Items are written after the model's training cutoff, held privately, and hashed into the manifest. The set is versioned and frozen, so the same items run before every release and a regression is a like-for-like reading.

Where is the work processed?

YPAI is a Norwegian limited company (AS). For EEA-pinned engagements the directly controlled processing chain stays inside the EEA. Sub-processor jurisdictions are itemised in the DPA.
