A single AI agent can summarize, analyze, or plan, but it struggles to scale across domains, maintain context, or specialize deeply enough for complex enterprise use cases. Multi-agent systems address these gaps by distributing responsibility across many specialized agents. Instead of asking one model to do everything, individual agents receive a defined role and scope. Each agent executes its part before results are stitched together. This avoids overload, reduces errors, and produces better outcomes than a single agent working alone.

Case in point: The CrewAI multi-agent platform structures multi-agent systems much like real-world teams. This design keeps workflows clear, predictable, and scalable while exposing the practical challenge of managing identity and access.…
