## BaseLLM Objects

```python theme={null}
class BaseLLM(BaseModel)
```

Base class for LLMs typically used by dynamic routes.

This class provides a base implementation for LLMs. It defines the common
configuration and methods for all LLM classes.

#### \_\_init\_\_

```python theme={null}
def __init__(name: str, **kwargs)
```

Initialize the BaseLLM.

**Arguments**:

* `name` (`str`): The name of the LLM.
* `**kwargs` (`dict`): Additional keyword arguments for the LLM.

#### \_\_call\_\_

```python theme={null}
def __call__(messages: List[Message]) -> Optional[str]
```

Call the LLM.

Must be implemented by subclasses.

**Arguments**:

* `messages` (`List[Message]`): The messages to pass to the LLM.

**Returns**:

`Optional[str]`: The response from the LLM.

#### extract\_function\_inputs

```python theme={null}
def extract_function_inputs(
        query: str, function_schemas: List[Dict[str,
                                                Any]]) -> List[Dict[str, Any]]
```

Extract the function inputs from the query.

**Arguments**:

* `query` (`str`): The query to extract the function inputs from.
* `function_schemas` (`List[Dict[str, Any]]`): The function schemas to extract the function inputs from.

**Returns**:

`List[Dict[str, Any]]`: The function inputs.
