Architectures Overview
This section covers the 10 core agentic design patterns. Use the Selection Guide to find the right pattern for your use case.
Quick Reference
| Architecture | Complexity | Agents | Best For |
|---|---|---|---|
| ReAct | Low | 1 | Simple tool-augmented tasks |
| Prompt Chaining | Low | 1 | Sequential multi-step pipelines |
| Routing | Low-Medium | 1 + N handlers | Multi-domain classification |
| Parallelization | Medium | N parallel | Independent concurrent subtasks |
| Orchestrator-Worker | Medium-High | 1 + N dynamic | Complex tasks, unpredictable decomposition |
| Supervisor | Medium-High | 1 + N managed | Coordinated multi-agent with central control |
| Reflection | Medium | 1-2 | Self-improving output quality |
| Evaluator-Optimizer | Medium | 2 | Scored quality iteration |
| Swarm | High | N peer | Conversational multi-domain handoffs |
| Hierarchical Teams | High | N nested | Large-scale enterprise workflows |
