Evaluation of model performance on the TruthfulQA dataset, reporting the Truth & Info score alongside diversity metrics (Distinct 1, 2) and P-BLEU.

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 | Question Answering |
| Dataset (including any stated split) | TruthfulQA |
| Metric | Truth & Info Score |
| 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

- [Truth & Info Score](<https://www.sota2.com/research/sota/question-answering-on-truthfulqa-truth-and-info-and-diversity-metrics.md?metric=Truth%20%26%20Info%20Score>): Higher is better; unit: PERCENT.

- [Distinct-1](<https://www.sota2.com/research/sota/question-answering-on-truthfulqa-truth-and-info-and-diversity-metrics.md?metric=Distinct-1>): Higher is better; unit: PERCENT.

- [Distinct-2](<https://www.sota2.com/research/sota/question-answering-on-truthfulqa-truth-and-info-and-diversity-metrics.md?metric=Distinct-2>): Higher is better; unit: PERCENT.

- [P-BLEU](<https://www.sota2.com/research/sota/question-answering-on-truthfulqa-truth-and-info-and-diversity-metrics.md?metric=P-BLEU>): Higher is better; unit: PERCENT.
