Mem0 now supports **Graph Memory**.
With Graph Memory, users can now create and utilize complex relationships between pieces of information, allowing for more nuanced and context-aware responses.
This integration enables users to leverage the strengths of both vector-based and graph-based approaches, resulting in more accurate and comprehensive information retrieval and generation.

## Initialize Graph Memory
To initialize Graph Memory you'll need to set up your configuration with graph
store providers. Currently, we support [Neo4j](#initialize-neo4j), [Memgraph](#initialize-memgraph), [Neptune Analytics](#initialize-neptune-analytics), [Neptune DB Cluster](#initialize-neptune-db),and [Kuzu](#initialize-kuzu) as graph store providers.

You can setup [Neo4j](https://neo4j.com/) locally or use the hosted [Neo4j AuraDB](https://neo4j.com/product/auradb/).
<Note>If you are using Neo4j locally, then you need to install [APOC plugins](https://neo4j.com/labs/apoc/4.1/installation/).</Note>

Note: You can use Neptune Analytics as part of an Amazon tech stack [Setup AWS Bedrock, AOSS, and Neptune](https://docs.mem0.ai/examples/aws_example#aws-bedrock-and-aoss)
Create an instance of Amazon Neptune Analytics in your AWS account following the [AWS documentation](https://docs.aws.amazon.com/neptune-analytics/latest/userguide/get-started.html).
- Public connectivity is not enabled by default, and if accessing from outside a VPC, it needs to be enabled.
- Once the Amazon Neptune Analytics instance is available, you will need the graph-identifier to connect.
- The Neptune Analytics instance must be created using the same vector dimensions as the embedding model creates. See: [Vector indexing in Neptune Analytics](https://docs.aws.amazon.com/neptune-analytics/latest/userguide/vector-index.html).

## Using Multiple Agents with Graph Memory
When working with multiple agents and sessions, you can use the `agent_id` and `run_id` parameters to organize memories by user, agent, and run context. This allows you to:
