Un guide complet pour construire un assistant de recherche IA avec AutoGPT

Diving into the World of AI Agents

Artificial Intelligence (AI) agents are systems that perceive their environment and take actions to achieve specific goals. These agents can range from simple devices, such as a thermostat adjusting the temperature based on its surroundings, to complex systems like a self-driving car navigating through traffic. AI agents form the core of many modern technologies, including recommendation systems and voice assistants. In this tutorial, we will equip an AI agent with additional tools and a specific model to fulfill its role as an AI research assistant.

What is AutoGPT?

AutoGPT is an experimental open-source application that leverages the capabilities of the GPT-4 language model. It's designed to autonomously achieve any goal set for it by chaining together GPT-4's "thoughts". This makes it one of the first examples of GPT-4 running fully autonomously, pushing the boundaries of what is possible with AI.

AutoGPT comes with a variety of features, including internet access for searches and information gathering, long-term and short-term memory management, text generation using GPT-4, access to popular websites and platforms, and file storage and summarization with GPT-3.5. It also offers extensibility with plugins.

Despite its capabilities, AutoGPT is not a polished application or product, but rather an experiment. It may not perform well in complex, real-world business scenarios, and it can be quite expensive to run due to the costs associated with using the GPT-4 language model. Therefore, it's important to set and monitor your API key limits with OpenAI.

Technologies Used in This Tutorial

An Overview of the LangChain

LangChain is a Python library designed to assist in the development of applications that leverage the capabilities of large language models (LLMs). These models are transformative technologies that enable developers to build applications that were previously not possible. However, using these LLMs in isolation is often insufficient for creating truly powerful apps - the real power comes when you can combine them with other sources of computation or knowledge.

LangChain provides a standard interface for LLMs and includes features for prompt management, prompt optimization, and common utilities for working with LLMs. It also supports sequences of calls, whether to an LLM or a different utility, through its Chains feature. Furthermore, LangChain offers functionalities for Data Augmented Generation, which involves specific types of chains that first interact with an external data source to fetch data for use in the generation step.

Introduction to Flask

Flask is a lightweight web framework for Python. It's designed to be simple and easy to use, but it's also powerful enough to build complex web applications. With Flask, you can create routes to handle HTTP requests, render templates to display HTML, and use extensions to add functionality like user authentication and database integration.

Exploring the Basics of the ReactJS

ReactJS, often simply called React, is a popular JavaScript library for building user interfaces. Developed by Facebook, React allows developers to create reusable UI components and manage the state of their applications efficiently. React is known for its virtual DOM, which optimizes rendering and improves performance in web applications.

Prerequisites

• Basic knowledge of Python, preferably with web frameworks such as Flask.
• Basic knowledge of LangChain and/or AI Agents such as AutoGPT.
• Intermediate knowledge of TypeScript and ReactJS for frontend development is a plus, but not necessary.

Outline

1. Initializing the Environment
2. Developing the Backend
3. Developing the Frontend
4. Testing the AI Research Assistant App

Initializing the Environment

Before we start building our application, we need to set up our development environment. This involves creating a new project for both the backend and frontend, and installing the necessary dependencies.

Backend Setup

Our backend will be built using Flask, a lightweight web framework for Python. To start, create a new directory for your project and navigate into it:

mkdir ai-research-assistant
cd ai-research-assistant

Next, create a new virtual environment. This keeps the dependencies required by different projects separate by creating isolated Python environments:

python -m venv venv

Activate the virtual environment:

source venv/bin/activate  # On Windows use `venv\Scripts\activate`

Now, install Flask and other necessary libraries:

pip install Flask langchain python-dotenv google-search-results openai tiktoken faiss-cpu

In this segment, we will go over the libraries necessary for our project:

• Flask: This is a lightweight and flexible Python web framework that provides the basic functionality needed to build web applications, such as routing, request and response handling, and template rendering.
• LangChain: LangChain is an AI-oriented tool that helps us build applications using the OpenAI GPT-3 model. It provides features like chat history management, tool management, and message formatting.
• python-dotenv: This library helps us manage application configuration in a .env file, which is then loaded into the environment when the application starts.
• google-search-results: This Python client for the SerpApi lets us programmatically perform Google searches and retrieve the results.
• OpenAI: This is the official Python client for the OpenAI API, which provides a convenient interface for us to interact with OpenAI's models.
• tiktoken: Developed by OpenAI, this library allows us to count tokens in text strings without making an API call.
• faiss-cpu: FAISS is a library developed for efficient similarity search and clustering of high-dimensional vectors.

Ces bibliothèques fonctionneront ensemble pour créer notre assistant de recherche en IA.

Frontend Setup

Notre frontend sera construit en utilisant ReactJS avec TypeScript. Pour commencer, assurez-vous d'avoir Node.js et npm installés sur votre machine. Vous pouvez télécharger Node.js ici et npm est inclus dans l'installation.

Ensuite, installez Create React App, un outil qui configure une application web moderne en exécutant une commande :

npx create-react-app ai-research-client --template typescript

Naviguez dans votre nouveau répertoire de projet :

cd ai-research-client

Maintenant, installez les bibliothèques nécessaires :

npm install axios tailwindcss

Developing the Backend

Plongeons dans le code ! Commencez par créer un fichier app.py, puis saisissez le code nécessaire pour construire votre application Flask...

Testing the AI Research App

Ça y est, c'est le moment de vérité ! Avant d'exécuter notre frontend, assurez-vous que notre backend est déjà en cours d'exécution...

Conclusion

Tout au long de ce tutoriel, nous avons exploré le pouvoir d'AutoGPT...

Les résultats ont été assez satisfaisants ! L'agent IA a efficacement fourni des résultats dans un délai constant sans rencontrer de boucles.
