Evaluation of Question Answering performance on the 500-question subset of the LongMemEval dataset, measured by QA accuracy.

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 | Question Answering |
| Dataset (including any stated split) | LongMemEval 500 questions |
| Metric | QA Accuracy |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 12 of 12 |
| 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

- [QA Accuracy](<https://www.sota2.com/research/sota/question-answering-on-longmemeval-500-questions.md?metric=QA%20Accuracy>): Higher is better; unit: PERCENT.
