PersistBench - Memory Sycophancy: leaderboard
Evaluates appropriate use of persistent memories. Cross-domain leakage and sycophancy each use 200 cases, counting failure in any of three generations; beneficial memory uses 100 cases with one generation. Lower failure is better, including failures to use beneficial memory. This series reports Memory Sycophancy using Failure Rate (%). Source: the original paper result table.
Metric: Failure Rate (%). Source: arxiv.org. 18 models tracked.
