Evaluation of model performance on the GPQA Diamond dataset for Question Answering, focusing on Accuracy, response Length, and the count of reflections per answer.

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 | Question Answering |
| Dataset (including any stated split) | GPQA Diamond |
| Metric | Accuracy |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 9 of 9 |
| 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

- [Accuracy](<https://www.sota2.com/research/sota/question-answering-on-gpqa-diamond-accuracy-length-reflection-count.md?metric=Accuracy>): Higher is better; unit: PERCENT.

- [Response Length](<https://www.sota2.com/research/sota/question-answering-on-gpqa-diamond-accuracy-length-reflection-count.md?metric=Response%20Length>): Higher is better; unit: SCALAR.

- [Reflection Count per Answer](<https://www.sota2.com/research/sota/question-answering-on-gpqa-diamond-accuracy-length-reflection-count.md?metric=Reflection%20Count%20per%20Answer>): Lower is better; unit: SCALAR.
