title: Configurations
---


Config in mem0 is a dictionary that specifies the settings for your embedding models. It allows you to customize the behavior and connection details of your chosen embedder.

## How to define configurations?

The config is defined as an object (or dictionary) with two main keys:
- `embedder`: Specifies the embedder provider and its configuration
  - `provider`: The name of the embedder (e.g., "openai", "ollama")
  - `config`: A nested object or dictionary containing provider-specific settings


## How to use configurations?

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 = {
    "embedder": {
        "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
import { Memory } from 'mem0ai/oss';

const config = {
  embedder: {
    provider: 'openai',
    config: {
      apiKey: process.env.OPENAI_API_KEY || '',
      model: 'text-embedding-3-small',
      // Provider-specific settings go here
    },
  },
};

const memory = new Memory(config);
await memory.add("Your text here", { userId: "user", metadata: { category: "example" } });
```
</CodeGroup>

## Why is Config Needed?

Config is essential for:
1. Specifying which embedding model to use.
2. Providing necessary connection details (e.g., model, api_key, embedding_dims).
3. Ensuring proper initialization and connection to your chosen embedder.

## Master List of All Params in Config
