This project demonstrates working with both OpenAI and Anthropic models in a command-line interface application. + +## Overview + +This application serves as a practical example of building a chat interface that can seamlessly switch between different AI providers.

OpenAI +2. Anthropic +Enter your choice (1 or 2): +``` + +After selecting a model, you can start chatting with the AI.

This project demonstrates how to convert natural language responses from Large Language Models (LLMs) into strongly-typed Java objects without writing complex parsing logic. - -## Why Structured Output Matters - -Working with AI models typically means dealing with unstructured text responses. Converting these responses into usable data structures traditionally requires: - -- Writing custom parsing logic -- Handling edge cases and malformed responses -- Maintaining complex regex patterns or string manipulation code -- Implementing error handling for parsing failures - -Spring AI eliminates these challenges by providing built-in conversion capabilities that transform AI responses directly into Java objects. This project showcases this functionality through a practical example: converting information about technical authors into structured data. - -## Project Overview - -This application demonstrates structured output conversion by: -1. Taking user input for a technical author's name -2. Querying an AI model for information about the author -3. Automatically converting the response into a strongly-typed `AuthorInfo` object -4. Displaying the structured information to the user - -## Requirements - -- Java 17 or higher -- OpenAI API key -- Spring Boot 3.2 or higher -- Spring AI dependencies - -## Project Structure - -``` -src/ -├── main/ -│ ├── java/ -│ │ └── io/spring/examples/ -│ │ ├── Application.java # Main application class -│ │ └── AuthorInfo.java # Data structure for author information -│ └── resources/ -│ └── application.properties # Configuration properties -``` - -## Key Features - -### Structured Data Model - -The `AuthorInfo` record defines our structured output format: - -```java -public record AuthorInfo( - String name, - String primaryGenre, - List notableBooks, - int yearsActive, - String specialization -) {} -``` - -### Automatic Conversion - -Spring AI handles the conversion from AI response to Java object automatically: - -```java -var authorInfo = chat.prompt() - .user(u -> { - u.text("Please give me information about ${author}"); - u.param("author", authorName); - }) - .call() - .entity(AuthorInfo.class); // Automatic conversion to AuthorInfo -``` - -## Getting Started - -1. Set your OpenAI API key: - ```bash - export OPENAI_API_KEY=your-api-key-here - ``` - -2. Run the application: - ```bash - ./mvnw spring-boot:run - ``` - -3. Enter author names when prompted: - ``` - Who is your favorite technical author?

This project demonstrates how to convert natural language responses from Large Language Models (LLMs) into strongly-typed Java objects without writing complex parsing logic. + +## Why Structured Output Matters + +Working with AI models typically means dealing with unstructured text responses. Converting these responses into usable data structures traditionally requires: + +- Writing custom parsing logic +- Handling edge cases and malformed responses +- Maintaining complex regex patterns or string manipulation code +- Implementing error handling for parsing failures + +Spring AI eliminates these challenges by providing built-in conversion capabilities that transform AI responses directly into Java objects. This project showcases this functionality through a practical example: converting information about technical authors into structured data. + +## Project Overview + +This application demonstrates structured output conversion by: +1.
