#### config\_list\_from\_dotenv

```python theme={null}
config_list_from_dotenv(
    dotenv_file_path: str | None = None,
    model_api_key_map: dict[str, Any] | None = None,
    filter_dict: dict[str, list[str | None] | set[str | None]] | None = None
) -> list[dict[str, str | set[str]]]
```

Load API configurations from a specified .env file or environment variables and construct a list of configurations.<br />This function will: <br />- Load API keys from a provided .env file or from existing environment variables.<br />- Create a configuration dictionary for each model using the API keys and additional configurations.<br />- Filter and return the configurations based on provided filters.<br />model\_api\_key\_map will default to `\{"gpt-4": "OPENAI_API_KEY", "gpt-3.5-turbo": "OPENAI_API_KEY"}` if none
