Evaluation of language modeling performance using the 1.5% corrupted test split of the WikiText-103 dataset, typically measured by Perplexity (PPL).

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 | Language Modeling |
| Dataset (including any stated split) | WikiText-103 1.5% corruption (test) |
| Metric | Perplexity (PPL) |
| Unit | SCALAR |
| 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

- [Perplexity (PPL)](<https://www.sota2.com/research/sota/language-modeling-on-wikitext-103-1-5-percent-corruption-test.md?metric=Perplexity%20(PPL)>): Lower is better; unit: SCALAR.
