Compare model candidates on the same question

Use a common Dataset and test basis to examine candidate differences.

Read the guide

A useful candidate comparison starts with the same question and a fair basis. Keep each candidate’s source, settings, results, and costs of interpretation identifiable.

Best for

  • Teams choosing a model for a defined use
  • Practitioners evaluating a replacement candidate

What you’ll need

  • Candidate Models or verified API profiles
  • A common Dataset and Test plan

What you’ll keep

  • Separate identifiable Runs for the candidates
  • A comparison tied to the recorded measurements and limits

Help me plan a fair comparison of these model candidates for the stated use. Identify which Dataset version, tests, metrics, and settings must stay common, and which source settings differ. Prepare separate Runs for review and explain limitations before drawing a conclusion.

Define the decision question

State the task, intended use, and criterion. Make the choice depend on the needed behavior rather than selecting a convenient aggregate metric after seeing results.

Hold the test basis common

Use the same reviewed Dataset version, Test plan, and relevant conditions. Preserve the configuration needed for each Model or API profile. Prepare a separate Run for each candidate.

Examine the results together

Review each Run’s measurements, examples, coverage, and report. Explain differences in the source settings or omitted tests when interpreting the comparison.

Record the selected use

If the comparison informs an Assessment, link the selected evidence and record the human conclusion and decision there. Keep the other candidate’s result available for review.
