Welcome to the Spring AI Tutorial — your complete step-by-step guide to building your first AI-powered app with Java Spring Boot! 🚀

In this video, you’ll learn how to integrate ChatGPT-style LLMs into your Spring Boot projects using the Spring AI module. We’ll start from scratch, set up the project dependencies, create our first AI-enabled REST API, and go behind the scenes to understand how Spring AI auto-configures the OpenAI Chat Model for you.

💡 What You’ll Learn

Setting up the spring-ai-openai-spring-boot-starter dependency

Connecting your app to OpenAI with an API key

Using ChatClient to build prompts and stream AI responses

Reactive vs blocking calls — RestClient vs WebClient explained

Testing AI endpoints with Postman

Understanding User, System, and Assistant roles in message context

How DefaultChatClient and ChatModel work internally in Spring AI

Building a simple AI chat app with Spring Boot + Java

By the end, you’ll understand not only how to build an AI app but also why Spring AI simplifies AI integration by handling model configuration, message streaming, and API communication for you.
