Neo4j + GraphRAG in Action: Live Refactor with Jennifer Reif In this live coding session I am joined by @jmhreif from @neo4j to refactor an AI powered file search application from PostgreSQL to Neo4j. The goal is to mo...

Going live today, 20:00 CEST 🚀

Jennifer Reif (@neo4j.com) and I are adding graph traversal on top of vector search and seeing what breaks (and what gets better). Expect a bit of chaos.

🚀 LangChain4j CDI 1.1.0 released! New: CDI-aware guardrails for AI service input/output validation, ManagedExecutorService support, and LangChain4j 1.12.2 upgrade. Thanks to Buhake Sindi and Hervé Boutémy! #Java #AI #JakartaEE #LangChain4J

You don’t need a greenfield project to add AI.

In this episode, Alex Soto takes an existing Quarkus app and uses IBM Bob to integrate LangChain4j — incrementally, safely, and without architectural chaos.
