Specify the preference
A preference pair contains the same prompt, two candidate responses and a reason one is preferred. The reason matters: correctness, completeness, format and tone are different dimensions. If one answer is accurate but terse and another is polished but false, an overall preference without a rubric can teach the wrong trade-off.
Keep comparisons fair
Give reviewers the same evidence the model was allowed to use. Hide irrelevant identifiers that could bias the choice. Permit a tie or an ungradable result where the task genuinely does not support a confident decision. Record those outcomes instead of forcing arbitrary winners. Check whether response length is inadvertently determining the labels.
What to request from a provider
Ask for the prompt, both responses, the selected preference, rubric version and reviewer rationale in an agreed format. Separate a preference-data delivery from a promise of model improvement: the latter requires an experiment on unseen tasks. Zeton lists preference pairs among its training-data services; a buyer still needs to specify domain expertise, sampling and the treatment of disagreement.
