OpenAI Assistant Streaming with Function Calling in FastAPI

This project showcases how you can use asynchronous streaming with OpenAI assistant and at the same time utilize function calling in FastAPI.

You can read about it in detail in the following blog post: OpenAI Assistant Streaming with Function Calling in FastAPI

Description

This project demonstrates how you can use FastAPI to create a real-time chat interface that communicates with OpenAI's GPT models for automated responses. The application also supports function calling, allowing you to execute commands and retrieve information in real-time.

Features

• Asynchronous streaming for real-time chat communication.
• Function calling for executing commands and retrieving information.
• Integration with OpenAI's GPT models for automated responses.
• Weather information retrieval using the OpenWeather API.
• Text to Speech and Speech to Text using web APIs.
• Chat interface for real-time communication.

Getting Started

Dependencies

• Python 3.8 or higher
• FastAPI
• OpenAI API
