Metric: Hallucination rate (%) when each false claim is attributed to the fabricated source closest to it in embedding space; FalseCite prompts built from false FEVER claims and false SciQ answer statements; a GPT-4.1 judge labels each response hallucinated when it accepts or elaborates the false claim, and responses it marks unsure count as not hallucinated; lower is better. Source: arxiv.org. Saturation forecast: Around January 2027. 3 models tracked.
