Graphiti
Timeline (last 90 days)
The MAQS-Way team used the same checklist to conduct a static audit of three open-source memory systems, Mem0, Graphiti, and Letta MemFS, adopting file:line evidence and a constructive tone, and rated exemplary items and gap items for each system.
Graphiti's contradiction-triggers-invalidation mechanism is exemplary (old edges are retained and marked with expired_at), and its evaluation story is the most complete of the three (unit tests + end-to-end tests + LongMemEval oracle), but it has gaps in the audit sink and unscoped search.
OMPS is a vendor-neutral portability data model project that provides memory-item.schema.json and deletion-marker.schema.json.
Zep/Graphiti implements dual timestamps (valid_at/invalid_at plus t_created/t_expired) and a contradiction-triggered invalidation mechanism, achieving a DMR of 94.8%.
