Framework to create applications and model adapters for AI DIAL

AI DIAL Python SDK

Overview

Framework to create applications and model adapters for AI DIAL.

Applications and model adapters implemented using this framework will be compatible with AI DIAL API that was designed based on Azure OpenAI API.

Usage

Install the library using pip:

pip install aidial-sdk

Echo application example

The echo application example replies to the user by repeating their last message:

# Save this as app.py
import uvicorn

from aidial_sdk import DIALApp
from aidial_sdk.chat_completion import ChatCompletion, Request, Response


# ChatCompletion is an abstract class for applications and model adapters
class EchoApplication(ChatCompletion):
    async def chat_completion(
        self, request: Request, response: Response
    ) -> None:
        # Get last message (the newest) from the history
        last_user_message = request.messages[-1]

        # Generate response with a single choice
        with response.create_single_choice() as choice:
            # Fill the content of the response with the last user's content
            choice.append_content(last_user_message.content or "")


# DIALApp extends FastAPI to provide an user-friendly interface for routing requests to your applications
app = DIALApp()
app.add_chat_completion("echo", EchoApplication())

# Run built app
if __name__ == "__main__":
    uvicorn.run(app, port=5000)
