Knowledge graph
Memory stored as entities and relationships rather than flat text. Enables multi-hop reasoning ("who works at the company that supplies X").
Entity types (person, project, tool, decision) plus typed edges (works_at, supplies, depends_on). Bi-temporal model tracks valid_from/valid_to per fact. Confidence scores per observation. Difference vs vector search: vector search finds similar text, graph traversal follows real relationships. Knowledge graph is the gating feature that separates premium memory plans from free ones at most vendors — Mem0 charges $249/mo for it, StudioMeyer Memory includes it from free tier.
