The rapid advancements in Generative AI (Gen AI) are reshaping how modern applications are designed, built, and deployed. As AI-driven systems become a cornerstone of contemporary software, it is increasingly important for developers to learn how to effectively integrate Gen AI capabilities into production-ready solutions.

This book is a hands-on guide to developing intelligent, conversational applications powered by Python 3.12. You’ll learn how to build a full-stack chatbot system using Flask, LangChain, and the OpenAI API, supported by a robust Flask REST API and a MySQL 8 database for persistent storage.

Through clear examples and practical walkthroughs, you'll create a Gen AI-powered chatbot application that includes:

· A Web-Based Chat Interface with Flask – An interactive user interface that allows users to engage with the chatbot through natural language.

· A LangChain-Powered Conversational Engine – Harnessing LangChain’s capabilities to manage conversation history, memory, and agent tools.

· Integration with the OpenAI API – Connecting your app with OpenAI’s powerful models to generate intelligent and contextual responses.

· A Flask REST API Backend – A modular RESTful architecture to handle order-related operations including creation, updates, cancellations, and status tracking.

· A MySQL 8 Database – A reliable relational database backend for storing user data, order information, and conversation logs.

Whether you're a seasoned developer or just beginning your AI journey, this book equips you with the skills to build scalable, AI-driven chatbot applications from the ground up using modern Python tools and frameworks.
