Evaluation of LLM fingerprinting techniques on the Qwen 7B 2.5 dataset, measured using AUC and KS Statistic.

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 | LLM fingerprinting |
| Dataset (including any stated split) | Qwen 7B 2.5 |
| Metric | AUC |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 10 of 10 |
| 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

- [AUC](<https://www.sota2.com/research/sota/llm-fingerprinting-on-qwen-7b-2-5.md?metric=AUC>): Higher is better; unit: PERCENT.

- [KS Statistic](<https://www.sota2.com/research/sota/llm-fingerprinting-on-qwen-7b-2-5.md?metric=KS%20Statistic>): Higher is better; unit: PERCENT.
