Evaluation of model performance on the test split of SQuAD version 1.1 for Open-Domain Question Answering, reporting Acc@20 and Acc@100 scores.

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) | SQuAD v1.1 (test) |
| Metric | Acc@20 |
| 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

- [Acc@20](<https://www.sota2.com/research/sota/open-domain-question-answering-on-squad-v1-1-test.md?metric=Acc%4020>): Higher is better; unit: PERCENT.

- [Acc@100](<https://www.sota2.com/research/sota/open-domain-question-answering-on-squad-v1-1-test.md?metric=Acc%40100>): Higher is better; unit: PERCENT.
