LangChain4J: A great framework for AI integration in Java
LangChain4j is an excellent framework for building AI-based applications in Java. It provides a unified API over many different LLM providers, including OpenAI, Mistral, Gemini, and Claude. It does the same with a variety of embedding stores, making it easy to implement Retrieval Augmented Generation (RAG) to add your own data to the models.
This workshop discusses how to set up the framework, then teaches how to use prompt templates, conversations, function calling (tool support), automatic conversions from JSON into Java classes and records, and more.
