Graphiti

Builds a temporally-aware knowledge graph for agent memory.

Graphiti is an open-source framework from Zep for building real-time, temporally-aware knowledge graphs for AI agents. It incrementally ingests structured and unstructured data into a graph where facts carry validity windows, tracking when information became true and when it was superseded, and retrieves context via combined semantic, keyword, and graph-traversal search. It is notable for adding temporal reasoning and provenance to agent memory rather than relying solely on vector RAG.
