Evaluation of model preference alignment capabilities on the UltraFeedback dataset, reporting Win Rates derived from both a Reward Model and GPT-4o-mini evaluations.

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.

| Scope | Recorded value |
| --- | --- |
| Task | Preference Alignment |
| Dataset (including any stated split) | UltraFeedback |
| Metric | Win Rate (RM Evaluator) |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 3 of 3 |
| Coverage | All results currently returned for this benchmark |

Evaluation settings may differ between results. The original papers and recorded configurations are needed to establish comparability. A shared metric name alone does not establish an identical protocol.

## Metrics

- [Win Rate (RM Evaluator)](<https://www.sota2.com/research/sota/preference-alignment-on-ultrafeedback-rm-and-gpt-4o-mini-evaluators.md?metric=Win%20Rate%20(RM%20Evaluator)>): Higher is better; unit: PERCENT.

- [Win Rate (GPT-4o-mini Evaluator)](<https://www.sota2.com/research/sota/preference-alignment-on-ultrafeedback-rm-and-gpt-4o-mini-evaluators.md?metric=Win%20Rate%20(GPT-4o-mini%20Evaluator)>): Higher is better; unit: PERCENT.

- [Average Win Rate](<https://www.sota2.com/research/sota/preference-alignment-on-ultrafeedback-rm-and-gpt-4o-mini-evaluators.md?metric=Average%20Win%20Rate>): Higher is better; unit: PERCENT.
