5 architecture patterns for multi-agent systems: sequential, parallel, supervisor, hierarchical, debate

Shalini Goyal outlined 5 architecture patterns for building multi-agent systems, noting the choice determines how agents communicate, share information, and divide work:
- Sequential: each agent completes a step before passing on (researcher→analyst→writer→reviewer) — simple, predictable, easy to debug.
- Parallel: multiple agents work on different parts simultaneously, outputs combined — lower latency, good for large information-gathering.
- Supervisor: a central agent coordinates specialized agents, deciding dispatch, tasks, and termination — fits dynamic workflows.
- Hierarchical: manager→team leads→specialists, an AI org chart for large projects.
- Debate/peer review: agents independently analyze and critique each other, targeting better reasoning rather than consensus — for high-stakes decisions.
