PersistBench - Beneficial Memory: 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 Beneficial Memory using Failure Rate (%). Source: the original paper result table.

Metric: Failure Rate (%). Source: arxiv.org. Saturation forecast: Estimated already saturated. 18 models tracked.
