Can we skip humans if the judge is good?

You can reduce them. You should not eliminate them on dimensions that would create legal, safety, or reputational harm. The hybrid split is the design.

Do you provide the annotators?

Sometimes, through a senior contractor network and domain SMEs. Often we design the programme and your people — or a labelling partner you already have — run it. Capability is meant to stay with you.

What if raters disagree?

Then the rubric or the item is unclear. Disagreement is information. We adjudicate, tighten the guide, or split the dimension. We do not hide it in an average.

Solutions

Human and hybrid evaluation programs

Where automation cannot see the failure, a human must — trained, calibrated, and measured. Unstructured “eyeballing” is not a programme. Agreement is the score of the scoring.

For high-stakes or subjective dimensions: tone in a regulated reply, clinical or legal nuance, preference between two fluent answers, or the slice an LLM-judge keeps missing.

Guidelines before raters

A rater without a guideline is improvising. We write the guide from the rubric, train on it, and keep a calibration set that is scored again as people drift. New raters do not join a live queue until they match the standard.

Guidelines are short enough to use under time pressure and specific enough to survive a disagreement. If two trained people cannot apply a sentence the same way, the sentence is wrong — not the people.

Agreement is part of the ledger

Inter-annotator agreement is tracked. Disagreements are adjudicated, not averaged away. Preference ranking and pairwise comparison are used when the question is “which is better,” not “is this true.” The method follows the decision.

Adjudication is logged. A later reader should see why the gold label is the gold label. Hidden consensus is how human eval becomes theatre.

Hybrid by default

Humans are expensive. The design is usually hybrid: automatic scores on the bulk, human review on a sample, on disagreements, and on the critical slice. Cost is an evaluation parameter, not an embarrassment.

The sample is not random courtesy. It is stratified by slice and by the auto-score’s uncertainty. That is how a small panel still sees the cases that would fail a gate.

What the programme holds

These artifacts are what make a human score repeatable.

Rater guidelines

The same definition of the dimension, in writing

Calibration set

Whether people still agree with last month

Agreement report

IAA, adjudication log, rater notes

Sampling rule

What the humans see, and what the auto-score covers

Engagement

Typical shape: Framework + Pilot, or a workstream inside Full Build / retainer, typically designed in weeks; operated on a cadence you keep. Duration is typical, not contractual. Formats and deliverables are written on the evaluation ledger.
