Codepocalypse Now: LangChain4j vs. Spring AI

Which Java framework handles AI better: LangChain4j or Spring AI? In this live coding showdown, we’ll build a semantic code search application from scratch, putting both frameworks to the test. We’ll cover project setup, using language models, setting up a retrieval-augmented generation workflow, and creating a REST API.You’ll see how these frameworks handle embedding generation, vector database integration, and real-world development challenges. By the end, the audience decides who wins—based on which framework gets the job done faster, better, and with less hassle (and whether the demo actually works).This isn’t just a comparison; it’s a live experiment under pressure. Come and see which one comes out on top!

Baruch Sadogursky (@jbaruch) did Java before it had generics, DevOps before there was Docker, and DevRel before it had a name. He started DevRel at JFrog when it was ten people and took it all the way to a successful $6B IPO by helping engineers solve problems. Now Baruch keeps helping engineers solve problems but also helps companies help engineers solve problems. He is a co-author of the "Liquid Software" and "DevOps Tools for Java Developers" books, Java Champion and CNCF Ambassador alumni, serves on multiple conference program committees, and regularly speaks at numerous most prestigious industry conferences, including Kubecon, JavaOne (RIP), Devoxx, QCon, DevRelCon, DevOpsDays (all over), DevOops (not a typo) and others.
