LexAgentHallu - LRAS - L2 Hallucination Frequency: leaderboard
LexAgentHallu evaluates hallucinations in multi-step legal agents. L1 covers substantive legal knowledge and L2 procedural reasoning. Hallucination frequency is the fraction of rollouts with at least one flagged error; density is the mean fraction of applicable error subclasses triggered. Frameworks are separate protocols; the LRAS fine-tuned models retain their own identities. This series reports LexAgentHallu - LRAS - L2 Hallucination Frequency from 2609.09754v1, S4.T2: Hallucination Frequency (%). Lower is better.
Metric: Hallucination Frequency (%). Source: arxiv.org. Saturation forecast: Rough model projection: around 2026. 3 models tracked.
