Evaluation of model performance on the test split of the MMhops Bridging dataset for multi-hop question answering.

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) | MMhops Bridging (test) |
| Metric | String Success Rate |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 13 of 13 |
| 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

- [String Success Rate](<https://www.sota2.com/research/sota/multi-hop-question-answering-on-mmhops-bridging-test.md?metric=String%20Success%20Rate>): Higher is better; unit: PERCENT.

- [Numerical Success Rate](<https://www.sota2.com/research/sota/multi-hop-question-answering-on-mmhops-bridging-test.md?metric=Numerical%20Success%20Rate>): Higher is better; unit: PERCENT.

- [Average Inference Time](<https://www.sota2.com/research/sota/multi-hop-question-answering-on-mmhops-bridging-test.md?metric=Average%20Inference%20Time>): Lower is better; unit: TIME.

- [Overall Score](<https://www.sota2.com/research/sota/multi-hop-question-answering-on-mmhops-bridging-test.md?metric=Overall%20Score>): Higher is better; unit: PERCENT.
