Talk: Agentic Patterns - Lets build a Game!
Abstract:
Graduate from single agents to full multi-agent systems. We’ll explore eight patterns that power production AI: chain agents that work like an assembly line, fan-out for parallel expert opinions, loops that run until a critic approves, and routing requests to the right specialist. Then we’ll unlock Supervisor agents that delegate like project managers, and Human-in-the-Loop gates for cases where humans need the final say. Finally, we’ll explore goal-oriented planners that find optimal paths and peer-to-peer meshes where agents collaborate as equals without a central boss.
Then well see how Agents Brown, Jones, and Smith can fight Neo in pixel-art combat rounds — powered by GPT-5-nano on Azure AI Services, deployed to Azure Container Apps, using three LangChain4j agentic patterns (Sequential, Parallel, Loop). Toggle "Neo is The One" to flip the odds and watch Neo dominate.Social media links:
