EverMemBench (Full Context) - Memory Awareness (Proactivity): leaderboard
EverMemBench (Hu et al., 2026) tests long-horizon memory over simulated multi-party workplace chat: five year-long projects, about 845,000 tokens of group dialogue each, and 2,400 questions, here with the whole dialogue history in the model's context. Recalling explicit rules and flagging a new instruction that would break them, even under persuasive framing; multiple choice, accuracy in percent, higher is better.
Metric: Accuracy (%; whole multi-party dialogue history in context, multiple choice). Source: arxiv.org. Saturation forecast: Estimated already saturated. 3 models tracked.
