About

Graphiti overview

Graphiti is an open-source temporal knowledge graph system from Zep for building agent memory that tracks entities, relationships, and changing facts over time.

Temporal knowledge graph model

Graphiti represents memory as entities and relationships with time-aware context.

This helps agents reason about changing facts instead of flattening everything into chunks.

Agent memory orientation

The project is built for agent and assistant memory workflows.

It focuses on recall structures that matter to agents, not just generic graph storage.

Open-source implementation

The repository and docs provide a concrete path for evaluation.

Graph memory is easier to trust when the implementation is inspectable.
Use cases

When to use Graphiti

Customer or user memory

Track evolving relationships, preferences, and events across time.

Research knowledge graphs

Represent entities and links discovered during research workflows.

Agent context retrieval

Retrieve facts by relationship and recency rather than only semantic similarity.

Compare

How it compares

Graphiti is stronger for relational memory vs vector-only memory

Vector search is useful for fuzzy recall; Graphiti is more appropriate when relationships and time matter.

FAQ

Questions

What should I check before using Graphiti?

Test Graphiti with repeated sessions. Add facts, update them, ask for recall, inspect retrieval behavior, and verify deletion or scoping controls before storing sensitive user or project memory.

Is Graphiti open source?

Graphiti is listed with Apache-2.0 based on the official source links in this profile. Re-check the repository, model card, or docs before production use.

Who should evaluate Graphiti?

Graphiti is most worth evaluating for builders who need graph memory instead of simple chat history.
