@mydeveloperplanet.comIn this blog, you will learn how to implement Retrieval Augmented Generation (RAG) using PGVector, LangChain4j and Ollama. This implementation allows you to ask questions about your documents using natural language.
#java #langchain4j
@langchain4j.dev#LangChain4j 1.22.0 is out!
Highlights:
- OpenAI Decisions API support
- AWS Bedrock batch inference
- Automatic prompt caching for Anthropic
Thanks to all contributors!

@kevindubois.comNew achievement unlocked: finish up a post while waiting for our @devoxx.com talk to start & post it live during the session. This time it's a refactor w/ the #LangChain4j DecisionModel and DecisionRouterPlanner (& adding "Kev" model because how could I not 😁)
@sciam.frHier matin @yblazart.bsky.social et @antoine.sabot-durand.net ont aidé à animer le lab de @ehsavoie.bsky.social sur #LangChain4J-CDI #Devoxx
@antoine.sabot-durand.netFirst @devoxx.com session. Our lab on #Langchain4j-CDI is packed. With @ehsavoie.bsky.social and @yblazart.bsky.social
@ehsavoie.bsky.socialIf you want to know how to inject LLM into your application as easily as an EntityManager in ALL the mp or Jakartaee runtimes ,come tomorrow morning lnkd.in/ezb7XCQJ

@mydeveloperplanet.comIn this blog, you will take a closer look at embedding documents to be used for a semantic search. By means of examples, you will learn how embedding influences the search results.

Meet Decision Models: instant yes/no, choice and scale answers with probabilities.
Decision Services turn any Java interface into a classifier.
Plus model routing, re-ranking, tool selection, guardrails and agentic routing!
@mydeveloperplanet.comIn this blog, you will take a closer look at how you can chat with your documents using LangChain4j and LocalAI. Besides that, you will learn some basics about prompt engineering. Enjoy!

@kevindubois.comI wrote a follow up on my #Jev + #LangChain4j blog post since I was able to sign up and get an actual API key this time 😄. (and added a few more features to the project)
@mydeveloperplanet.comThis post discusses integrating LLM capabilities into Java applications using LangChain4j. It covers using LocalAI, provides examples, and explores chatting with documents.

@glaforge.devPlanning your #Devoxx Belgium schedule? With 200+ talks across 8 parallel tracks, picking sessions takes time.
I built a personalized agenda generator using #Micronaut, #LangChain4j, and #Gemini 3.5 Flash-Lite on #Java 25 virtual threads!
Here is how it works 🧵👇
@kevindubois.comWith all this hype around #Jev and open source derivatives like #Laya I wanted to see how these kinds of decision models would work in Agentic Workflows with #LangChain4j. (tl;dr it's pretty intuitive!)
@kevindubois.comWho will give our #Quarkus #LangChain4j Workshop its 100th star? 🌟 🤩
