Evaluation of model performance on the HotpotQA dataset for multi-hop question answering, focusing specifically on query latency and inference speed.

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 | Query Latency (s/q) |
| Unit | TIME |
| Direction | Lower is better |
| Results loaded | 8 of 8 |
| 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

- [Query Latency (s/q)](<https://www.sota2.com/research/sota/multi-hop-question-answering-on-hotpotqa-latency.md?metric=Query%20Latency%20(s%2Fq)>): Lower is better; unit: TIME.
