MEME (In-Context) - Exact Recall: leaderboard

Long-term conversational memory with the whole episode in context: about 35K tokens of multi-session dialogue about fictitious personal or software-project facts, then questions; MEME (Jung et al., 2026). Exact recall asks for a stated value verbatim; accuracy in percent from a GPT-4o judge, higher is better.

Metric: Accuracy (fraction x 100; the whole ~35K-token episode transcript, 32K tokens of filler around the evidence sessions, fed to the answering model with no memory system; GPT-4o judge; exact recall: reproduce a stated value verbatim). Source: arxiv.org. Saturation forecast: Estimated already saturated. 2 models tracked.
