Evaluation of Cross-size lineage similarity detection capabilities using the Qwen-2.5 series dataset, measured by SeedPrint, REEF, and HUREF metrics.

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 | Cross-size lineage similarity detection |
| Dataset (including any stated split) | Qwen-2.5 series |
| Metric | SeedPrint |
| Unit | SCALAR |
| 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

- [SeedPrint](<https://www.sota2.com/research/sota/cross-size-lineage-similarity-detection-on-qwen-2-5-series.md?metric=SeedPrint>): Higher is better; unit: SCALAR.

- [REEF](<https://www.sota2.com/research/sota/cross-size-lineage-similarity-detection-on-qwen-2-5-series.md?metric=REEF>): Lower is better; unit: SCALAR.

- [HUREF](<https://www.sota2.com/research/sota/cross-size-lineage-similarity-detection-on-qwen-2-5-series.md?metric=HUREF>): Lower is better; unit: SCALAR.
