The development of AI-powered automation often presents a key architectural decision:

• Should you build one large AI agent that integrates multiple tools?
• Or should you design multiple smaller agents, each specialized with a specific tool?

This choice impacts scalability, performance, maintainability, and cost-effectiveness. While a monolithic AI agent can centralize control and decision-making, micro agents promote modularity and flexibility.

This article explores the trade-offs between these two approaches, providing insights into when to choose each model.

1. Understanding the Two Approaches

1.1 Monolithic AI Agents Using Multiple Tools

A monolithic AI agent is a single, centralized AI system that handles all tasks by leveraging multiple tools within its framework.
