LangChain4j

If you build enterprise Java and keep hearing that AI means rewriting everything in Python, one number is worth sitting with: Azul's 2026 State of @java survey says 62% of organizations now use Java to code AI functionality, up from 50% a year ago. 1/5

As #AI applications grow, prompts become workflows—and workflows become systems. Read @LoMagnette's guide to mastering #LangChain4j Agentic Workflows, from simple agents to supervisor patterns, error handling & production-ready orchestration: javapro.io/2026/07/08/lan… @langchain4j

I had Fable 5 add this feature by looking at both the @langchain4j code base and the @DevoxxGenie project... awesome feature, make sure to install v1.8.12 of the plugin!🥳

Excited to share that @Hazelcast can now be used with @LangChain4j as a Chat Memory and Embedding Store, and for #LangGraph4j as a Workflow checkpoints’ store. - docs for LangChain4j - docs.langchain4j.dev/integrations/e… - docs for LangGraph4j - github.com/langgraph4j/la…

@maxandersen Congratulations!

Well that happened! Busiest week in years ends on a high note :) Thanks all!

#LangChain4j 1.17.0 is out! 🎉 github.com/langchain4j/la…

@hazelcast🤝 @langchain4j Great work by @AndriiRodionov! 🤩

New talk recording from @jPrimeConf! Run GPU-accelerated, local LLM inference in Java - from a @QuarkusIO @langchain4j app. No Python. No CUDA. Just Java. All inside the JVM - powered by #TornadoVM + GPULlama3. 🔗 youtu.be/9YCRUwr7pO8?si… #Java #GPU #LLM #AI #opensource

Today at Devoxx Poland: "Building secure AI agents with Quarkus LangChain4j" with Willem Jan Glerum & Radek Kargul on Friday from 11:30 - 14:30 in Lab 2 buff.ly/3G3T2Ky #quarkusworldtour

🚀 Breaking changes ahead: test-drive Quarkus MCP Server 2.0.0.Beta1 and shape the release! The latest draft of MCP (2026-07-28-RC) introduces significant breaking changes. Quarkus MCP Server 2.0.0.Beta1 aligns with these updates, bringing initial implementation of key features.

#LangChain4j 1.16.0 is out! github.com/langchain4j/la…

@langchain4j 1.15.0 shipped an integration with #Docling, @IBM Research's document parser. If you build #RAG in @Java, it lands on the messiest stage of the pipeline: getting clean text and tables out of real PDFs and DOCX. 1/5

The first release of the @Quarkusio @Langfuse extension is now available! This makes integration between #Quarkus, @LangChain4j, and #Langfuse super simple! It even includes a convenient dev service! See docs.quarkiverse.io/quarkus-langfu… for more information!

LangSmith does not need to stay in the Python corner. I wrote a Quarkus walkthrough that sends LangChain4j traces to LangSmith over OTLP, including plain chat, tool calls, and controlled failures. It also covers the two easy footguns: /otel vs /otel/v1/traces, and region-specific endpoints. the-main-thread.com/p/quarkus-lang… #langsmith #quarkus #java

Parallel voting and adaptive model selection: smarter agentic AI on a budget quarkus.io/blog/introduci… Check out how @langchain4j and @QuarkusIO can help you to save time and money allowing to dynamically select the AI model that best fit the current state of your agentic system.

@JamesWard @mydevlprplanet Sorry for the late reply. Currently, no, only release notes.

@langchain4j @mydevlprplanet Awesome! Anything better to link to from ai4jvm.com than the release notes?
