Evaluation of model performance and efficiency (cost and token usage) on the 2WikiMultiHopQA l2 subset 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) | 2WikiMultiHopQA l2 |
| Metric | Cost per Pass |
| Unit | SCALAR |
| Direction | Lower 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

- [Cost per Pass](<https://www.sota2.com/research/sota/multi-hop-question-answering-on-2wikimultihopqa-l2.md?metric=Cost%20per%20Pass>): Lower is better; unit: SCALAR.

- [Accuracy](<https://www.sota2.com/research/sota/multi-hop-question-answering-on-2wikimultihopqa-l2.md?metric=Accuracy>): Higher is better; unit: PERCENT.

- [Cost (¢)](<https://www.sota2.com/research/sota/multi-hop-question-answering-on-2wikimultihopqa-l2.md?metric=Cost%20(%C2%A2)>): Lower is better; unit: SCALAR.

- [Token Count](<https://www.sota2.com/research/sota/multi-hop-question-answering-on-2wikimultihopqa-l2.md?metric=Token%20Count>): Lower is better; unit: SCALAR.
