title: Configurations
icon: "gear"
iconType: "solid"

## How to define configurations?
The `config` is defined as an object with two main keys:
- `vector_store`: Specifies the vector database provider and its configuration
- `provider`: The name of the vector database (e.g., "chroma", "pgvector", "qdrant", "milvus", "upstash_vector", "azure_ai_search", "vertex_ai_vector_search", "valkey")
- `config`: A nested dictionary containing provider-specific settings
## How to Use Config
Here's a general example of how to use the config with mem0:
<CodeGroup>
```python Python
import os
from mem0 import Memory
os.environ["OPENAI_API_KEY"] = "sk-xx"
config = {
"vector_store": {
"provider": "your_chosen_provider",
"config": {
# Provider-specific settings go here
}
}
}
m = Memory.from_config(config)
m.add("Your text here", user_id="user", metadata={"category": "example"})
```
```typescript TypeScript
// Example for in-memory vector database (Only supported in TypeScript)
import { Memory } from 'mem0ai/oss';
const configMemory = {
vector_store: {
provider: 'memory',
config: {
collectionName: 'memories',
dimension: 1536,
},
},
};
const memory = new Memory(configMemory);
await memory.add("Your text here", { userId: "user", metadata: { category: "example" } });
```
</CodeGroup>
<Note>
The in-memory vector database is only supported in the TypeScript implementation.
</Note>
## Why is Config Needed?
Config is essential for:
1. Specifying which vector database to use.
2. Providing necessary connection details (e.g., host, port, credentials).
3. Customizing database-specific settings (e.g., collection name, path).
4. Ensuring proper initialization and connection to your chosen vector store.
## Master List of All Params in Config
Here's a comprehensive list of all parameters that can be used across different vector databases:

## Customizing Config
Each vector database has its own specific configuration requirements. To customize the config for your chosen vector store:
1. Identify the vector database you want to use from [supported vector databases](./dbs).
2. Refer to the `Config` section in the respective vector database's documentation.
3. Include only the relevant parameters for your chosen database in the `config` dictionary.
## Supported Vector Databases
For detailed information on configuring specific vector databases, please visit the [Supported Vector Databases](./dbs) section. There you'll find individual pages for each supported vector store with provider-specific usage examples and configuration details.

title: Azure AI Search
---
[Azure AI Search](https://learn.microsoft.com/azure/search/search-what-is-azure-search/) (formerly known as "Azure Cognitive Search") provides secure information retrieval at scale over user-owned content in traditional and generative AI search applications.
## Usage
```python
import os
from mem0 import Memory
os.environ["OPENAI_API_KEY"] = "sk-xx" # This key is used for embedding purpose
config = {
"vector_store": {
"provider": "azure_ai_search",
"config": {
"service_name": "<your-azure-ai-search-service-name>",
"api_key": "<your-api-key>",
"collection_name": "mem0",
"embedding_model_dims": 1536
}
}
}
m = Memory.from_config(config)
messages = [
{"role": "user", "content": "I'm planning to watch a movie tonight. Any recommendations?"},
{"role": "assistant", "content": "How about a thriller movies? They can be quite engaging."},
{"role": "user", "content": "I'm not a big fan of thriller movies but I love sci-fi movies."},
{"role": "assistant", "content": "Got it! I'll avoid thriller recommendations and suggest sci-fi movies in the future."}
]
m.add(messages, user_id="alice", metadata={"category": "movies"})
```
## Using binary compression for large vector collections
```python
config = {
"vector_store": {
"provider": "azure_ai_search",
"config": {
"service_name": "<your-azure-ai-search-service-name>",
"api_key": "<your-api-key>",
"collection_name": "mem0",
"embedding_model_dims": 1536,
"compression_type": "binary",
"use_float16": True # Use half precision for storage efficiency
}
}
}
```
## Using hybrid search
```python
config = {
"vector_store": {
"provider": "azure_ai_search",
"config": {
"service_name": "<your-azure-ai-search-service-name>",
"api_key": "<your-api-key>",
"collection_name": "mem0",
"embedding_model_dims": 1536,
"hybrid_search": True,
"vector_filter_mode": "postFilter"
}
}
}
```
## Using Azure Identity for Authentication
As an alternative to using an API key, the Azure Identity credential chain can be used to authenticate with Azure OpenAI. The list below shows the order of precedence for credential application:
1. **Environment Credential:**
Azure client ID, secret, tenant ID, or certificate in environment variables for service principal authentication.
2. **Workload Identity Credential:**
Utilizes Azure Workload Identity (relevant for Kubernetes and Azure workloads).
3. **Managed Identity Credential:**
Authenticates as a Managed Identity (for apps/services hosted in Azure with Managed Identity enabled), this is the most secure production credential.
4. **Shared Token Cache Credential / Visual Studio Credential (Windows only):**
Uses cached credentials from Visual Studio sign-ins (and sometimes VS Code if SSO is enabled).
5. **Azure CLI Credential:**
Uses the currently logged-in user from the Azure CLI (`az login`), this is the most common development credential.
6. **Azure PowerShell Credential:**
Uses the identity from Azure PowerShell (`Connect-AzAccount`).
7. **Azure Developer CLI Credential:**
Uses the session from Azure Developer CLI (`azd auth login`).
<Note> If an API is provided, it will be used for authentication over an Azure Identity </Note>
To enable Role-Based Access Control (RBAC) for Azure AI Search, follow these steps:
1. In the Azure Portal, navigate to your **Azure AI Search** service.
2. In the left menu, select **Settings** > **Keys**.
3. Change the authentication setting to **Role-based access control**, or **Both** if you need API key compatibility. The default is “Key-based authentication”—you must switch it to use Azure roles.
4. **Go to Access Control (IAM):**
- In the Azure Portal, select your Search service.
- Click **Access Control (IAM)** on the left.
5. **Add a Role Assignment:**
- Click **Add** > **Add role assignment**.
6. **Choose Role:**
- Mem0 requires the **Search Index Data Contributor** and **Search Service Contributor** role.
7. **Choose Member**
- To assign to a User, Group, Service Principle or Managed Identity:
- For production it is recommended to use a service principal or managed identity.
- For a service principal: select **User, group, or service principal** and search for the service principal.
- For a managed identity: select **Managed identity** and choose the managed identity.
- For development, you can assign the role to a user account.
- For development: select ***User, group, or service principal** and pick a Azure Entra ID account (the same used with `az login`).
8. **Complete the Assignment:**
- Click **Review + Assign**.
If you are using Azure Identity, do not set the `api_key` in the configuration.
```python
config = {
"vector_store": {
"provider": "azure_ai_search",
"config": {
"service_name": "<your-azure-ai-search-service-name>",
"collection_name": "mem0",
"embedding_model_dims": 1536,
"compression_type": "binary",
"use_float16": True # Use half precision for storage efficiency
}
}
}
```
### Environment Variables to set to use Azure Identity Credential:
* For an Environment Credential, you will need to setup a Service Principal and set the following environment variables:
- `AZURE_TENANT_ID`: Your Azure Active Directory tenant ID.
- `AZURE_CLIENT_ID`: The client ID of your service principal or managed identity.
- `AZURE_CLIENT_SECRET`: The client secret of your service principal.
* For a User-Assigned Managed Identity, you will need to set the following environment variable:
- `AZURE_CLIENT_ID`: The client ID of the user-assigned managed identity.
* For a System-Assigned Managed Identity, no additional environment variables are needed.
### Developer logins to use for a Azure Identity Credential:
* For an Azure CLI Credential, you need to have the Azure CLI installed and logged in with `az login`.
* For an Azure PowerShell Credential, you need to have the Azure PowerShell module installed and logged in with `Connect-AzAccount`.
* For an Azure Developer CLI Credential, you need to have the Azure Developer CLI installed and logged in with `azd auth login`.
Troubleshooting tips for [Azure Identity](https://github.com/Azure/azure-sdk-for-python/blob/main/sdk/identity/azure-identity/TROUBLESHOOTING.md#troubleshoot-environmentcredential-authentication-issues).
## Configuration Parameters
| Parameter | Description | Default Value | Options |
| --- | --- | --- | --- |
| `service_name` | Azure AI Search service name | Required | - |
| `api_key` | API key of the Azure AI Search service | Optional | If not present, the [Azure Identity](#using-azure-identity-for-authentication) credential chain will be used |
| `collection_name` | The name of the collection/index to store vectors | `mem0` | Any valid index name |
| `embedding_model_dims` | Dimensions of the embedding model | `1536` | Any integer value |
| `compression_type` | Type of vector compression to use | `none` | `none`, `scalar`, `binary` |
| `use_float16` | Store vectors in half precision (Edm.Half) | `False` | `True`, `False` |
| `vector_filter_mode` | Vector filter mode to use | `preFilter` | `postFilter`, `preFilter` |
| `hybrid_search` | Use hybrid search | `False` | `True`, `False` |
## Notes on Configuration Options
- **compression_type**:
- `none`: No compression, uses full vector precision
- `scalar`: Scalar quantization with reasonable balance of speed and accuracy
- `binary`: Binary quantization for maximum compression with some accuracy trade-off
- **vector_filter_mode**:
- `preFilter`: Applies filters before vector search (faster)
- `postFilter`: Applies filters after vector search (may provide better relevance)
- **use_float16**: Using half precision (float16) reduces storage requirements but may slightly impact accuracy. Useful for very large vector collections.
- **Filterable Fields**: The implementation automatically extracts `user_id`, `run_id`, and `agent_id` fields from payloads for filtering.

### Authentication
Databricks Vector Search supports two authentication methods:
#### Service Principal (Recommended for Production)
```python
config = {
"vector_store": {
"provider": "databricks",
"config": {
"workspace_url": "https://your-workspace.databricks.com",
"service_principal_client_id": "your-service-principal-id",
"service_principal_client_secret": "your-service-principal-secret",
"endpoint_name": "your-endpoint",
"index_name": "catalog.schema.index_name",
"source_table_name": "catalog.schema.source_table"
}
}
}
```
#### Personal Access Token (for Development)
```python
config = {
"vector_store": {
"provider": "databricks",
"config": {
"workspace_url": "https://your-workspace.databricks.com",
"access_token": "your-personal-access-token",
"endpoint_name": "your-endpoint",
"index_name": "catalog.schema.index_name",
"source_table_name": "catalog.schema.source_table"
}
}
}
```
### Embedding Options
#### Self-Managed Embeddings (Default)
Use your own embedding model and provide vectors directly:
```python
config = {
"vector_store": {
"provider": "databricks",
"config": {
# ... authentication config ...
"embedding_dimension": 768, # Match your embedding model
"embedding_vector_column": "embedding"
}
}
}
```
#### Databricks-Computed Embeddings
Let Databricks compute embeddings from text using a serving endpoint:
```python
config = {
"vector_store": {
"provider": "databricks",
"config": {
# ... authentication config ...
"embedding_source_column": "text",
"embedding_model_endpoint_name": "e5-small-v2"
}
}
}
```
### Important Notes
- **Delta Sync Index**: This implementation uses Delta Sync Index, which automatically syncs with your source Delta table. Direct vector insertion/deletion/update operations will log warnings as they're not supported with Delta Sync.
- **Unity Catalog**: Both the source table and index must be in Unity Catalog format (`catalog.schema.table_name`).
- **Endpoint Auto-Creation**: If the specified endpoint doesn't exist, it will be created automatically.
- **Index Auto-Creation**: If the specified index doesn't exist, it will be created automatically with the provided configuration.
- **Filter Support**: Supports filtering by metadata fields, with different syntax for STANDARD vs STORAGE_OPTIMIZED endpoints.

| `password` | Password for basic authentication | `None` |
| `verify_certs` | Whether to verify SSL certificates | `True` |
| `auto_create_index` | Whether to automatically create the index | `True` |
| `custom_search_query` | Function returning a custom search query | `None` |
| `headers` | Custom headers to include in requests | `None` |
### Features
- Efficient vector search using Elasticsearch's native k-NN search
- Support for both local and cloud deployments (Elastic Cloud)
- Multiple authentication methods (Basic Auth, API Key)
- Automatic index creation with optimized mappings for vector search
- Memory isolation through payload filtering
- Custom search query function to customize the search query
### Custom Search Query
The `custom_search_query` parameter allows you to customize the search query when `Memory.search` is called.
__Example__
```python
import os
from typing import List, Optional, Dict
from mem0 import Memory
def custom_search_query(query: List[float], limit: int, filters: Optional[Dict]) -> Dict:
return {
"knn": {
"field": "vector",
"query_vector": query,
"k": limit,
"num_candidates": limit * 2
}
}
os.environ["OPENAI_API_KEY"] = "sk-xx"
config = {
"vector_store": {
"provider": "elasticsearch",
"config": {
"collection_name": "mem0",
"host": "localhost",
"port": 9200,
"embedding_model_dims": 1536,
"custom_search_query": custom_search_query
}
}
}
```
It should be a function that takes the following parameters:
- `query`: a query vector used in `Memory.search`
- `limit`: a number of results used in `Memory.search`
- `filters`: a dictionary of key-value pairs used in `Memory.search`. You can add custom pairs for the custom search query.
The function should return a query body for the Elasticsearch search API.

[FAISS](https://github.com/facebookresearch/faiss) is a library for efficient similarity search and clustering of dense vectors. It is designed to work with large-scale datasets and provides a high-performance search engine for vector data. FAISS is optimized for memory usage and search speed, making it an excellent choice for production environments.
### Usage
```python
import os
from mem0 import Memory
os.environ["OPENAI_API_KEY"] = "sk-xx"
config = {
"vector_store": {
"provider": "faiss",
"config": {
"collection_name": "test",
"path": "/tmp/faiss_memories",
"distance_strategy": "euclidean"
}
}
}
m = Memory.from_config(config)
messages = [
{"role": "user", "content": "I'm planning to watch a movie tonight. Any recommendations?"},
{"role": "assistant", "content": "How about a thriller movies? They can be quite engaging."},
{"role": "user", "content": "I'm not a big fan of thriller movies but I love sci-fi movies."},
{"role": "assistant", "content": "Got it! I'll avoid thriller recommendations and suggest sci-fi movies in the future."}
]
m.add(messages, user_id="alice", metadata={"category": "movies"})
```
### Installation
To use FAISS in your mem0 project, you need to install the appropriate FAISS package for your environment:
```bash
# For CPU version
pip install faiss-cpu
# For GPU version (requires CUDA)
pip install faiss-gpu
```
### Config
Here are the parameters available for configuring FAISS:
| Parameter | Description | Default Value |
| --- | --- | --- |
| `collection_name` | The name of the collection | `mem0` |
| `path` | Path to store FAISS index and metadata | `/tmp/faiss/<collection_name>` |
| `distance_strategy` | Distance metric strategy to use (options: 'euclidean', 'inner_product', 'cosine') | `euclidean` |
| `normalize_L2` | Whether to normalize L2 vectors (only applicable for euclidean distance) | `False` |
### Performance Considerations
FAISS offers several advantages for vector search:
1. **Efficiency**: FAISS is optimized for memory usage and speed, making it suitable for large-scale applications.
2. **Offline Support**: FAISS works entirely locally, with no need for external servers or API calls.
3. **Storage Options**: Vectors can be stored in-memory for maximum speed or persisted to disk.
4. **Multiple Index Types**: FAISS supports different index types optimized for various use cases (though mem0 currently uses the basic flat index).
### Distance Strategies
FAISS in mem0 supports three distance strategies:
- **euclidean**: L2 distance, suitable for most embedding models
- **inner_product**: Dot product similarity, useful for some specialized embeddings
- **cosine**: Cosine similarity, best for comparing semantic similarity regardless of vector magnitude
When using `cosine` or `inner_product` with normalized vectors, you may want to set `normalize_L2=True` for better results.

title: LangChain
---
Mem0 supports LangChain as a provider for vector store integration. LangChain provides a unified interface to various vector databases, making it easy to integrate different vector store providers through a consistent API.
<Note>
When using LangChain as your vector store provider, you must set the collection name to "mem0". This is a required configuration for proper integration with Mem0.
</Note>
## Usage
<CodeGroup>
```python Python
import os
from mem0 import Memory
from langchain_community.vectorstores import Chroma
from langchain_openai import OpenAIEmbeddings
# Initialize a LangChain vector store
embeddings = OpenAIEmbeddings()
vector_store = Chroma(
persist_directory="./chroma_db",
embedding_function=embeddings,
collection_name="mem0" # Required collection name
)
# Pass the initialized vector store to the config

## Supported LangChain Vector Stores
LangChain supports a wide range of vector store providers, including:
- Chroma
- FAISS
- Pinecone
- Weaviate
- Milvus
- Qdrant
- And many more
You can use any of these vector store instances directly in your configuration. For a complete and up-to-date list of available providers, refer to the [LangChain Vector Stores documentation](https://python.langchain.com/docs/integrations/vectorstores).
## Limitations
When using LangChain as a vector store provider, there are some limitations to be aware of:
1. **Bulk Operations**: The `get_all` and `delete_all` operations are not supported when using LangChain as the vector store provider. This is because LangChain's vector store interface doesn't provide standardized methods for these bulk operations across all providers.
2. **Provider-Specific Features**: Some advanced features may not be available depending on the specific vector store implementation you're using through LangChain.
## Provider-Specific Configuration
When using LangChain as a vector store provider, you'll need to:
1. Set the appropriate environment variables for your chosen vector store provider
2. Import and initialize the specific vector store class you want to use
3. Pass the initialized vector store instance to the config
<Note>
Make sure to install the necessary LangChain packages and any provider-specific dependencies.
</Note>
## Config
All available parameters for the `langchain` vector store config are present in [Master List of All Params in Config](../config).

| ---------------------- | -------------------------------------------------------------------- | ------------- |
| `vector_bucket_name` | The name of the S3 Vector bucket to use. It will be created if it doesn't exist. | Required |
| `index_name` | The name of the vector index within the bucket. | `mem0` |
| `embedding_model_dims` | Dimensions of the embedding model. Must match your embedder. | `1536` |
| `distance_metric` | Distance metric for similarity search. Options: `cosine`, `euclidean`. | `cosine` |
| `region_name` | The AWS region where the bucket and index reside. | `None` (uses default from AWS config) |
### IAM Permissions
Your AWS identity (user or role) needs permissions to perform actions on S3 Vectors. A minimal policy would look like this:
```json
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": "s3vectors:*",
"Resource": "*"
}
]
}
```
For production, it is recommended to scope down the resource ARN to your specific buckets and indexes.

### SQL Migrations for TypeScript Implementation
The following SQL migrations are required to enable the vector extension and create the memories table:
```sql
-- Enable the vector extension
create extension if not exists vector;
-- Create the memories table
create table if not exists memories (
id text primary key,
embedding vector(1536),
metadata jsonb,
created_at timestamp with time zone default timezone('utc', now()),
updated_at timestamp with time zone default timezone('utc', now())
);
-- Create the vector similarity search function
create or replace function match_vectors(
query_embedding vector(1536),
match_count int,
filter jsonb default '{}'::jsonb
)
returns table (
id text,
similarity float,
metadata jsonb
)
language plpgsql
as $$
begin
return query
select
t.id::text,
1 - (t.embedding <=> query_embedding) as similarity,
t.metadata
from memories t
where case
when filter::text = '{}'::text then true
else t.metadata @> filter
end
order by t.embedding <=> query_embedding
limit match_count;
end;
$$;
```
Goto [Supabase](https://supabase.com/dashboard/projects) and run the above SQL migrations inside the SQL Editor.

| `collection_name` | Name for the vector collection | `mem0` |
| `embedding_model_dims` | Dimensions of the embedding model | `1536` |
| `index_method` | Vector index method to use | `auto` |
| `index_measure` | Distance measure for similarity search | `cosine_distance` |
</Tab>
<Tab title="TypeScript">
| Parameter | Description | Default Value |
| --- | --- | --- |
| `collectionName` | Name for the vector collection | `mem0` |
| `embeddingModelDims` | Dimensions of the embedding model | `1536` |
| `supabaseUrl` | Supabase URL | None |
| `supabaseKey` | Supabase key | None |
| `tableName` | Name for the vector table | `memories` |
</Tab>
</Tabs>
### Index Methods
The following index methods are supported:
- `auto`: Automatically selects the best available index method
- `hnsw`: Hierarchical Navigable Small World graph index (faster search, more memory usage)
- `ivfflat`: Inverted File Flat index (good balance of speed and memory)
### Distance Measures
Available distance measures for similarity search:
- `cosine_distance`: Cosine similarity (recommended for most embedding models)
- `l2_distance`: Euclidean distance
- `l1_distance`: Manhattan distance
- `max_inner_product`: Maximum inner product similarity
### Best Practices
1. **Index Method Selection**:
- Use `hnsw` for fastest search performance when memory is not a constraint
- Use `ivfflat` for a good balance of search speed and memory usage
- Use `auto` if unsure, it will select the best method based on your data
2. **Distance Measure Selection**:
- Use `cosine_distance` for most embedding models (OpenAI, Hugging Face, etc.)
- Use `max_inner_product` if your vectors are normalized
- Use `l2_distance` or `l1_distance` if working with raw feature vectors
3. **Connection String**:
- Always use environment variables for sensitive information in the connection string
- Format: `postgresql://user:password@host:port/database`

[Upstash Vector](https://upstash.com/docs/vector) is a serverless vector database with built-in embedding models.
### Usage with Upstash embeddings
You can enable the built-in embedding models by setting `enable_embeddings` to `True`. This allows you to use Upstash's embedding models for vectorization.
```python
import os
from mem0 import Memory
os.environ["UPSTASH_VECTOR_REST_URL"] = "..."
os.environ["UPSTASH_VECTOR_REST_TOKEN"] = "..."
config = {
"vector_store": {
"provider": "upstash_vector",
"enable_embeddings": True,
}
}
m = Memory.from_config(config)
m.add("Likes to play cricket on weekends", user_id="alice", metadata={"category": "hobbies"})
```
<Note>
Setting `enable_embeddings` to `True` will bypass any external embedding provider you have configured.
</Note>
### Usage with external embedding providers
```python
import os
from mem0 import Memory
os.environ["OPENAI_API_KEY"] = "..."

## Usage
To utilize a vector database, you must provide a configuration to customize its usage. If no configuration is supplied, a default configuration will be applied, and `Qdrant` will be used as the vector database.
For a comprehensive list of available parameters for vector database configuration, please refer to [Config](./config).
## Common issues
### Using model with different dimensions
If you are using customized model, which is having different dimensions other than 1536
for example 768, you may encounter below error:
`ValueError: shapes (0,1536) and (768,) not aligned: 1536 (dim 1) != 768 (dim 0)`
you could add `"embedding_model_dims": 768,` to the config of the vector_store to overcome this issue.
