Evaluation of model performance on the HotpotQA dataset for multi-hop question answering, reporting Exact Match (EM), F1 score, Judge score, token usage, and context word count (Cw).

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 | Multi-hop Question Answering |
| Dataset (including any stated split) | HotpotQA |
| Metric | EM |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 7 of 7 |
| 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

- [EM](<https://www.sota2.com/research/sota/multi-hop-question-answering-on-hotpotqa-em-f1-judge-tokens-cw.md?metric=EM>): Higher is better; unit: PERCENT.

- [F1](<https://www.sota2.com/research/sota/multi-hop-question-answering-on-hotpotqa-em-f1-judge-tokens-cw.md?metric=F1>): Higher is better; unit: PERCENT.

- [Judge Score](<https://www.sota2.com/research/sota/multi-hop-question-answering-on-hotpotqa-em-f1-judge-tokens-cw.md?metric=Judge%20Score>): Higher is better; unit: PERCENT.

- [Tokens (M)](<https://www.sota2.com/research/sota/multi-hop-question-answering-on-hotpotqa-em-f1-judge-tokens-cw.md?metric=Tokens%20(M)>): Lower is better; unit: SIZE.

- [Context Words (Cw)](<https://www.sota2.com/research/sota/multi-hop-question-answering-on-hotpotqa-em-f1-judge-tokens-cw.md?metric=Context%20Words%20(Cw)>): Lower is better; unit: SIZE.
