Evaluation of model performance on the test split (v1.0) of the Natural Questions (NQ) dataset for Open-Domain Question Answering, measured using Top-K Accuracy (Acc@20, Acc@100).

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 | Open-Domain Question Answering |
| Dataset (including any stated split) | NaturalQuestions (NQ) v1.0 (test) |
| Metric | Acc@20 |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 11 of 11 |
| 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

- [Acc@20](<https://www.sota2.com/research/sota/open-domain-question-answering-on-naturalquestions-nq-v1-0-test.md?metric=Acc%4020>): Higher is better; unit: PERCENT.

- [Acc@100](<https://www.sota2.com/research/sota/open-domain-question-answering-on-naturalquestions-nq-v1-0-test.md?metric=Acc%40100>): Higher is better; unit: PERCENT.
