## How to define configurations?

<Tabs>
  <Tab title="Python">
    The `config` is defined as a Python dictionary with two main keys:
    - `llm`: Specifies the llm provider and its configuration
      - `provider`: The name of the llm (e.g., "openai", "groq")
      - `config`: A nested dictionary containing provider-specific settings
  </Tab>
  <Tab title="TypeScript">
    The `config` is defined as a TypeScript object with these keys:
    - `llm`: Specifies the LLM provider and its configuration (required)
      - `provider`: The name of the LLM (e.g., "openai", "groq")
      - `config`: A nested object containing provider-specific settings
    - `embedder`: Specifies the embedder provider and its configuration (optional)
    - `vectorStore`: Specifies the vector store provider and its configuration (optional)
    - `historyDbPath`: Path to the history database file (optional)
  </Tab>

### Config Values Precedence

Config values are applied in the following order of precedence (from highest to lowest):

1. Values explicitly set in the `config` object/dictionary
2. Environment variables (e.g., `OPENAI_API_KEY`, `OPENAI_BASE_URL`)
3. Default values defined in the LLM implementation

This means that values specified in the `config` will override corresponding environment variables, which in turn override default values.

## 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" # for embedder

config = {
    "llm": {
        "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';

// Minimal configuration with just the LLM settings
const config = {
  llm: {
    provider: 'your_chosen_provider',
    config: {
      // Provider-specific settings go here
    }
  }
};

const memory = new Memory(config);
await memory.add("Your text here", { userId: "user123", metadata: { category: "example" } });
```

</CodeGroup>

## Why is Config Needed?

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

## Master List of All Params in Config

Here's a comprehensive list of all parameters that can be used across different LLMs:
