Multi Agent Design Patterns | A Cost-Value Breakdown | Rakesh Gohel

Added: 2026-05-27

Multi-agent system design patterns vary significantly in cost and value: Sequential patterns have the lowest overhead, Parallel patterns compress time but multiply costs, Hierarchical patterns offer best long-term ROI when sub-agents are reusable, Generator-Critic patterns improve output quality through iterative review, Human-in-the-Loop patterns are essential for compliance and high-stakes decisions, and Composite patterns are most expensive and should only be used for end-to-end workflows where the full pattern stack genuinely earns its cost.
