Evaluation of model performance on the MedMCQA dataset focusing on medical information extraction and understanding, measured by Perplexity (PPL) and Accuracy (Acc).

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 | Medical information extraction and understanding |
| Dataset (including any stated split) | MedMCQA |
| Metric | Perplexity (PPL) |
| Unit | SCALAR |
| Direction | Lower 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

- [Perplexity (PPL)](<https://www.sota2.com/research/sota/medical-information-extraction-and-understanding-on-medmcqa.md?metric=Perplexity%20(PPL)>): Lower is better; unit: SCALAR.

- [Accuracy (%)](<https://www.sota2.com/research/sota/medical-information-extraction-and-understanding-on-medmcqa.md?metric=Accuracy%20(%25)>): Higher is better; unit: PERCENT.
