About

DyadMem annotates user-side memory and User-conditioned Relational Agent Memory (URAM) across 3,065 multi-session trajectories. It features session-level Capture/Update gold annotations and query-level Recall support.

Scoring uses Gold-Memory and Full-Pipeline QA settings to localize failures. Results show a significant performance drop in Full-Pipeline QA, revealing issues like low Capture recall and unsafe deletions in frontier LLMs.
