## What it measures

Pairwise human preferences produce task-specific ratings and published confidence bounds. A rating belongs to its board, model identity and observation period.

Undominated publishes a scoped set of accepted results; see the linked instrument for its exact task, date and coverage.

## What the result does not establish

 - Preference is not a measurement of your application’s correctness, reliability or operating cost.
- A text rating and an image-edit rating do not share a frontier. Neither does a model automatically inherit another variant’s result.
- Overlapping intervals make a rigid ordering harder to justify. Inspect the significance view before interpreting small displayed gaps.

## Hold these conditions constant

 - Same benchmark task and published snapshot
- Exact version and reasoning configuration
- Published confidence interval and observation coverage
- Application constraints such as tools, context and input modalities

## An evaluation for your team

Run the shortlisted models on the same representative prompts with blinded review. Define acceptable answers before scoring; separately record attempts, accepted results, observed cost and latency.

Write down the task version, attempt count, accepted outcomes, observed spend and latency. Preserve failures in the denominator. A new model version or tool configuration deserves a new record.
