PersTurnBench (Diverse Memory): leaderboard
Metric: User-macro satisfaction (1-5): calibrated predicted satisfaction averaged within each user and then across users, PersTurnBench replay of 300 turns from 90 users (180 user-task blocks): the candidate fills only the current assistant turn and the frozen Qwen3-8B memory evaluator predicts the user's turn satisfaction, reference-CDF calibrated per user, the candidate generator also given a diverse sample of user history; higher is better. Source: arxiv.org. Saturation forecast: Estimated already saturated. 3 models tracked.
