This workshop introduced participants to the concepts of building Large Language Model powered applications in Java using Quarkus and the LangChain4j library. Together, they developed an enterprise application that integrated generative AI. Starting from the basics, the workshop progressively added more complex features, showcasing the different aspects of working with LLMs. Key engineers from the Quarkus and LangChain4j projects delivered the workshop, providing participants with the opportunity to ask all their questions.

By the end of the day, attendees gained a good understanding of prompt engineering, model parameters, AI security aspects, and RAG.
