Short answer
The decision in plain language.
Start with the decision the evaluation supports. Define the unit of work, rubric, false-pass and false-fail consequences, reviewer capability, sample set, calibration method, disagreement route, data boundary, volume and acceptance threshold before asking for headcount or price.
Compare the operating models
Choose by who owns the work.
02
Staffed review team
Best when
You own the method and need validated reviewer capacity.
Tradeoff
Your team retains calibration and production management.
03
Managed evaluation operation
Best when
Recurring volume needs calibration, QA and adjudication ownership.
Tradeoff
Method, security and release boundaries must be explicit.

Buying questions
Questions to settle before you buy.
What can people evaluate?
Model outputs, conversations, documents, images, workflows, policy adherence, domain accuracy, language quality and other reviewable work defined in the scope.
How is reviewer quality established?
Through capability screening, shared examples, calibration rounds, disagreement analysis, sampling and a named adjudication route.
Who decides whether a model ships?
The buyer retains product, methodology, safety and release decisions unless a written scope assigns a bounded responsibility elsewhere.
