Evaluation of language models on the short context subset (\<32K tokens) of LongBench v2, focusing on Long-Context Inference tasks, measured by 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 | Long-Context Inference |
| Dataset (including any stated split) | LongBench \<32K tokens v2 (short) |
| Metric | Accuracy |
| Unit | PERCENT |
| Direction | Higher 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

- [Accuracy](<https://www.sota2.com/research/sota/long-context-inference-on-longbench-32k-tokens-v2-short.md?metric=Accuracy>): Higher is better; unit: PERCENT.
