_get_local_provider_call should return an AsyncOpenAI client when appropriate

Description

The _get_local_provider_call function in the Mirascope library is responsible for determining the type of client to return based on the context of execution. This function is crucial in ensuring that the correct client is used, whether it's a synchronous or asynchronous client. In this article, we will delve into the importance of returning an AsyncOpenAI client when appropriate and explore the code snippet that illustrates this discussion.

The Importance of Returning an AsyncOpenAI Client

When working with asynchronous programming, it's essential to use the correct type of client to avoid potential issues. In the case of OpenAI, the AsyncOpenAI client is designed to work seamlessly with asynchronous code, ensuring that requests are made efficiently and without blocking the execution of other tasks. On the other hand, the OpenAI client is designed for synchronous use cases and may not be suitable for asynchronous programming.

The Code Snippet

The code snippet provided illustrates the current implementation of the _get_local_provider_call function. The function checks if a client is already available and returns it if so. If not, it attempts to create a client using the OpenAI or AsyncOpenAI class, depending on the context of execution.

def _get_local_provider_call(
    provider: str,
    openai_call: Callable,
    client: Optional[Client] = None,
) -> Tuple[Callable, Client]:
    """
    Returns a client and a call function based on the provider.

    Args:
        provider (str): The provider to use.
        openai_call (Callable): The call function to use.
        client (Optional[Client], optional): The client to use. Defaults to None.

    Returns:
        Tuple[Callable, Client]: A tuple containing the call function and the client.
    """
    if client:
        return openai_call, client
    from openai import AsyncOpenAI, OpenAI

    try:
        asyncio.get_running_loop()
        client = AsyncOpenAI(api_key="ollama", base_url="http://localhost:11434/v1")
    except RuntimeError:
        client = OpenAI(api_key="ollama", base_url="http://localhost:11434/v1")
    return openai_call, client

The Issue with the Current Implementation

The current implementation of the _get_local_provider_call function has a potential issue. When the function attempts to create a client using the AsyncOpenAI class, it does so without checking if an asynchronous event loop is running. This can lead to a RuntimeError being raised if no event loop is running, causing the function to fall back to using the OpenAI client instead.

A Better Solution

To address this issue, we can modify the _get_local_provider_call function to check if an asynchronous event loop is running before attempting to create a client using the AsyncOpenAI class. If an event loop is running, we can create an AsyncOpenAI client; otherwise, we can fall back to using the OpenAI client.

def _get_local_provider_call(
    provider: str,
    openai_call: Callable,
    client: Optional[Client] = None,
) -> Tuple[Callable, Client]:
    """
    Returns a client and a call function based on the provider.

    Args:
        provider (str): The provider to use.
        openai_call (Callable): The call function to use.
        client (Optional[Client], optional): The client to use. Defaults to None.

    Returns:
        Tuple[Callable, Client]: A tuple containing the call function and the client.
    """
    if client:
        return openai_call, client
    from openai import AsyncOpenAI, OpenAI

    try:
        # Check if an asynchronous event loop is running
        asyncio.get_running_loop()
        # Create an AsyncOpenAI client if an event loop is running
        client = AsyncOpenAI(api_key="ollama", base_url="http://localhost:11434/v1")
    except RuntimeError:
        # Fall back to using the OpenAI client if no event loop is running
        client = OpenAI(api_key="ollama", base_url="http://localhost:11434/v1")
    return openai_call, client

Conclusion

In conclusion, the _get_local_provider_call function should return an AsyncOpenAI client when appropriate to ensure that the correct type of client is used in asynchronous programming. The code snippet provided illustrates the current implementation of the function, which has a potential issue with checking if an asynchronous event loop is running. By modifying the function to check for an event loop, we can create a more robust and efficient implementation that returns the correct type of client based on the context of execution.
