Stop building slow AI: Optimizing multi-agent systems for production

Build a Multi-Agent Marathon Planner with ADK and A2A → https://goo.gle/4nyWbRE [Demo] Race Condition → https://goo.gle/3Pbv16Z Join Casey West and Ivan Ardini as they break down the multi-agent architecture behind their Dev Keynote demo, revealing the secrets to optimizing complex AI systems for production constraints. Discover how to leverage the Agent Development Kit (ADK) to build specialized "planner," "simulator," and "evaluator" agents, and learn advanced techniques for real time evaluation using Gemini 3.1 Pro. Explore how to optimize Agent2Agent Protocol (A2A) communication using Pub/Sub, WebSockets, and protocol buffers, and master Agent-to-User Interface (A2UI) generation to build responsive, scalable frontends for cloud applications.
