What is the supervisor and worker pattern in Gemma 4?

It's a multi-agent setup where specialized worker agents handle narrow tasks (like log analysis or code gen), and a central supervisor — powered by Gemma 4's thinking mode — coordinates, validates, and routes flows via a state graph.

How do you build multi-agent systems with Gemma 4?

Use LangGraph for the state machine backbone. Define workers as tool-calling functions, supervisor as a reasoning router. Add validation nodes. Gemma 4 excels in the supervisor role thanks to structured thinking.

Does Gemma 4 make AI agents reliable for production?

Yes, via separation of reasoning and action, but only if you enforce output checks, bounded retries, and reversible action guards. Skip those, and it's hype.
