Multi-Agent System (MAS)

An architecture in which multiple specialized agents collaborate, often coordinated by an orchestrator.

Definition

Multi-agent designs split work among agents with distinct roles, tools or contexts, enabling parallelism and separation of concerns. They add coordination overhead, token cost and failure modes, so a single agent is preferred when sufficient.

Exam tip

Start with the simplest architecture; add agents only when it clearly improves results.
