A new research paper introduces a novel evaluation metric for grounded generation that addresses the limitations of existing faithfulness metrics. The paper highlights that current metrics primarily measure precision, rewarding models for abstaining from making claims, thus neglecting recall or coverage of relevant facts. By utilizing Formula 1 telemetry and NOAA weather forecasts as complete oracle domains, the researchers demonstrate that frontier models cover less than half of the relevant facts. The study also shows that fine-tuning smaller models on these complete oracles can significantly close the precision-recall gap, outperforming larger zero-shot systems. AI
