Welcome to the LLMChat repository! This full-stack implementation combines a robust API server built with Python FastAPI and an elegant frontend powered by Flutter to deliver a smooth user experience with advanced chat capabilities using ChatGPT and other LLM models. This blog post will guide you through the setup process, highlighting key features and troubleshooting tips.

Getting Started

Setting up LLMChat on your local machine is straightforward. Before diving into the steps, ensure that you have Docker and Docker Compose installed. If you prefer running the server without Docker, Python 3.11 is required alongside Docker for DB servers.

Step-by-Step Installation Instructions

• Clone the repository: Depending on your needs, choose one of the following commands:
• If you want to include Exllama or llama.cpp models:

  git clone --recurse-submodules https://github.com/c0sogillmchat.git

• If you only want core features (OpenAI):

  git clone https://github.com/c0sogillmchat.git

• Change to the project directory:

  cd LLMChat

• Create a .env file: Refer to the .env-sample file and enter your database and OpenAI API configurations.
• Run the server: Execute the following command to start your server.

  docker-compose -f docker-compose-local.yaml up

• Stop the server: If you need to stop it, simply run:

  docker-compose -f docker-compose-local.yaml down

• Access the server: Open your browser and go to http://localhost:8000/docs. You can access the app at http://localhost:8000/chat.

Understanding LLMChat Features Through An Analogy

Imagine LLMChat as a highly efficient restaurant that uses cutting-edge technology to serve your favorite dishes (the chat models). Here’s how each feature plays its role:

• FastAPI: The kitchen staff works rapidly to prepare your food, ensuring everything is fresh and quick.
• Flutter: This is the beautiful restaurant ambiance that makes your dining experience pleasant and attractive.
• ChatGPT Integration: This is your friendly waiter, always ready to take your orders and provide insights based on his extensive knowledge.
• Vectorstore: Think of this as a sophisticated pantry, where all ingredients are stored for quick retrieval to make dishes just right based on your previous orders.
• Auto Summarization: Just like a chef preparing bite-size portions of food, it condenses your conversations for a smoother experience.

Troubleshooting Tips

If you encounter issues, here are a few troubleshooting ideas:

• Make sure your Docker is running properly.
• Double-check your .env file for correct database and API key settings.
• Verify that you’ve cloned the repository correctly without missing any submodules.
• If you see an error related to the WebSocket connection, ensure that you are using a valid API key registered in the database.
