Guild42

Abstract
AI systems are moving beyond prompts to agents that plan, act and interact. And this time, Java is not catching up, it’s leading. Frameworks like LangChain4j and Embabel bring agentic capabilities with the strengths Java is built on: type safety, structure, reliability and testability.
Agents aren’t a passing hype. They are a necessary design pattern for robust AI systems, enforcing separation of concerns, controlled execution flows and human-in-the-loop checkpoints. They make complex AI interactions predictable, auditable and production ready.
This talk shows how the Java ecosystem is turning agentic design into a disciplined engineering approach, and how you can start replacing suitable parts of your processes using agents in a practical, production-ready way.

The talk will be held in English!
