Integrating Multiple LLMs into a Chatbot Application

In today's video, we will demonstrate how to integrate multiple industry-leading Language Model Models (LLMs), such as those from Open AI and Google, into a single chatbot application. We will present a framework that allows for easy addition of new models to your system, enabling you to enrich and empower your custom chatbot with models like Anthropic’s Claude. Our approach leverages the abstractions provided by LangChain, making the platform portable across different LLM API providers.

Introduction

In the field of conversational AI, chatbots have become increasingly popular. These chatbots utilize LLMs to generate human-like responses to user inputs. By integrating multiple LLMs into a single chatbot application, we can benefit from the strengths and capabilities of different models. In this article, we will explore the process of integrating multiple LLMs into a chatbot application using Python and Flask.

Integrating Multiple LLMs into a Chatbot Application

To build a chatbot that utilizes multiple LLMs, we need to have a framework in place that allows us to easily add and manage these models. One such framework is LangChain, which provides abstractions for interacting with different LLM API providers. With LangChain, we can keep our code simple and portable across different providers.

Building a Custom Chatbot with Python and Flask

To build our custom chatbot, we will be using Python code and the Flask framework. Flask is a lightweight web framework that allows us to Create web applications with minimal boilerplate code. If You are not familiar with Flask, don't worry - we will only be using a few dozen lines of code, and the concepts can be applied to other web frameworks as well.

Showcasing Responses from AI Models

Once we have our chatbot set up with multiple LLMs, we can showcase the responses from each model for a given user prompt. This can be useful for easily comparing and contrasting responses across different LLM providers in a unified web frontend. However, there are other use cases as well, such as synthesizing multiple responses across different models or incorporating filtering, scoring, or selection mechanisms to choose the best answers. The approach we highlight today can be tuned to a wide variety of use cases.

Managing Chat Sessions with LangChain

In order to have consistent and evolving engagement with the chatbot, we need to manage chat sessions across different models. LangChain helps us with this task, but we still need to handle session management to ensure a seamless conversation. We use a session ID cookie stored in the user's browser to maintain Context from previous messages. Additionally, we use a Chat Sessions variable to store all the sessions in memory. It's important to note that if the dev server is rebooted or the application's Docker container is restarted, previous chat history and context may be lost. For more production-grade session caching, external files or databases can be used.

Development Server Setup

To run our custom chatbot application, we need to set up a development server. We'll need the required dependencies and configurations to ensure everything runs smoothly. Our Flask code will handle routing and API requests, presenting the front-end code in an index.html file and using the Google and Open AI models to get responses for chatbot requests.

Frontend Setup for the Web Application

The frontend of our web application will consist of a chat box for messaging and an input interface for capturing user Prompts. We'll use HTML, CSS, and JavaScript to create a user-friendly interface. JavaScript functions will handle various frontend functionalities like appending messages to the chat box and sending messages as API requests to our Python Flask API.

Testing and Deployment of the Chatbot Application

Once our chatbot application is ready, it's time to test and deploy it. We can run a web preview server to test the application locally. We'll also discuss the process of authentication and environment setup for using the LLM models. Finally, we'll provide a Dockerfile for easy deployment of the application on various platforms like Amazon's EC2 or Google Cloud Run.
