ollama+ fastapi + litellm proxy + chainlit 进行chatapp 快速开发

Nginx and FastAPI are two software tools that are commonly used in web development. Nginx is a web server that can be used as a reverse proxy, load balancer, and HTTP cache. It is known for its high performance and scalability, and is often used to serve static content or to proxy requests to backend servers. Nginx can also be used to improve security by serving as a firewall or by performing SSL termination. FastAPI, on the other hand, is a modern, fast, web framework for building APIs with Python 3.7+ based on standard Python type hints. It is designed to be easy to use and to provide high performance, making it ideal for building microservices and APIs. FastAPI is also known for its automatic data validation and documentation generation.
