Evaluation of Distortion-Free Watermark performance on text generated by the LLaMA 3.1 8B model using the ELI5 64-bit bitstrings dataset. Key metrics include Message Accuracy, BA@1%FPR, and BA.

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 | Distortion-Free Watermark Evaluation |
| Dataset (including any stated split) | ELI5 64-bit bitstrings LLAMA3.1-8B |
| Metric | Message Accuracy |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 6 of 6 |
| 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

- [Message Accuracy](<https://www.sota2.com/research/sota/distortion-free-watermark-evaluation-on-eli5-64-bit-bitstrings-llama3-1-8b.md?metric=Message%20Accuracy>): Higher is better; unit: PERCENT.

- [BA @ 1% FPR](<https://www.sota2.com/research/sota/distortion-free-watermark-evaluation-on-eli5-64-bit-bitstrings-llama3-1-8b.md?metric=BA%20%40%201%25%20FPR>): Higher is better; unit: PERCENT.

- [BA](<https://www.sota2.com/research/sota/distortion-free-watermark-evaluation-on-eli5-64-bit-bitstrings-llama3-1-8b.md?metric=BA>): Higher is better; unit: PERCENT.
