Evaluation of general Natural Language Understanding capabilities using a 5-shot prompting strategy across the CSQA, HellaSwag, PIQA, SIQA, and ARC Easy benchmarks, reporting the Core Average score.

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 | Natural Language Understanding |
| Dataset (including any stated split) | NLU Benchmarks (CSQA, HellaSwag, PIQA, SIQA, ARC Easy) 5-shot |
| Metric | CSQA 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.
