The record

What it does: Graphiti is an open-source framework for building and querying temporal context graphs for AI agents.
Changing facts: It tracks when facts become valid and when they are superseded, preserving historical information for point-in-time queries.
Provenance: Graphiti links derived entities and relationships to the source episodes from which they came.
Retrieval: Its hybrid retrieval combines semantic search, keyword search, and graph traversal.
Data and ontology: It incrementally integrates structured and unstructured data and supports developer-defined entity and edge types using Pydantic models.
Graph databases: The repository lists Neo4j, FalkorDB, and Amazon Neptune as supported graph backends, and marks Kuzu as deprecated.
LLM integrations: The repository says Graphiti defaults to OpenAI and also supports Anthropic, Google Gemini, and Groq, with OpenAI-compatible providers usable through compatible endpoints.
MCP: The repository includes an MCP server for episode and entity management, relationship handling, semantic and hybrid search, group management, and graph maintenance.
API: The repository describes a REST API service built with FastAPI.
Requirements: The repository lists Python 3.10 or higher and an LLM API key among the requirements, and says structured-output-capable LLM services work best.
Security and support: The maker’s comparison says Graphiti is self-managed and self-hosted, while enterprise SLAs, support, and security guarantees are features of Zep.
License: The repository identifies Graphiti as open source and displays an Apache-2.0 license.
