First Official LangChain Meetup in Poland: AI Agents Workshop in Krakow

We're bringing LangChain to Poland

We're thrilled to announce that Lubu Labs is hosting the first official LangChain meetup in Poland. If you're building with AI agents, working on production GenAI systems, or curious about what it takes to ship reliable AI applications, this is the event for you.

Event Details:

• Location: Hevre, Krakow, Poland
• Date: February 19, 2026
• Format: AI Agents workshop + networking

What to expect

This isn't another "intro to LLMs" talk. We're going deep on production-ready patterns that teams actually use to ship AI systems.

Hands-on LangGraph workshops

Get practical experience building AI agents with LangGraph. You'll work through real patterns for:

• State machine design for multi-step agent workflows
• Human-in-the-loop patterns for critical decision points
• Error handling and recovery in agentic systems
• Checkpointing and persistence for long-running conversations

Production best practices

We'll cover the hard-won lessons from shipping AI to production:

• RAG reliability: What actually works when retrieval quality matters
• Evals and observability: How to measure and monitor AI system quality
• Debugging production issues: Using traces to understand what went wrong

LangSmith in production

See how teams use LangSmith for real production workloads:

• Tracing: End-to-end visibility into every LLM call
• Datasets: Building evaluation sets from production traffic
• Evals: Automated quality checks before and after deployment
• Feedback loops: Turning user feedback into system improvements
• Debugging: Finding and fixing issues fast

What you'll leave with

This is a practical event. By the end of the evening, you'll have:

• Production-ready patterns you can apply to your own projects immediately
• Hands-on workshop experience building with LangGraph
• New connections with builders and decision makers who are actively shipping GenAI

Whether you're a developer building AI features, a tech lead evaluating agentic architectures, or a founder exploring AI opportunities, you'll find value here.
