Graphiti Project Overview

Purpose

Graphiti is a Python framework for building and querying temporally-aware knowledge graphs, specifically designed for AI agents operating in dynamic environments. It continuously integrates user interactions, structured/unstructured data, and external information into a coherent, queryable graph with incremental updates and efficient retrieval.

Key Features

  • Bi-temporal data model: Explicit tracking of event occurrence times
  • Hybrid retrieval: Combining semantic embeddings, keyword search (BM25), and graph traversal
  • Custom entity definitions: Support via Pydantic models
  • Real-time incremental updates: No batch recomputation required
  • Multiple graph backends: Neo4j and FalkorDB support
  • Optional OpenTelemetry tracing: For distributed systems

Use Cases

  • Integrate and maintain dynamic user interactions and business data
  • Facilitate state-based reasoning and task automation for agents
  • Query complex, evolving data with semantic, keyword, and graph-based search methods

Relationship to Zep

Graphiti powers the core of Zep, a turn-key context engineering platform for AI Agents. This is the open-source version that provides flexibility for custom implementations.
