What is CrewAI?

From Single Agents to Agent Teams

Traditional AI applications use a single LLM to handle everything. Multi-agent systems take a different approach: specialized agents working together.

Single Agent vs Multi-Agent

Single Agent	Multi-Agent (CrewAI)
One LLM does everything	Specialized agents for each role
Limited expertise	Deep expertise per agent
Prompt engineering heavy	Role-based organization
Hard to maintain	Modular and scalable

Why Multi-Agent Systems?

Consider writing a research report. A single agent must:

• Search for information
• Analyze data
• Write content
• Edit and refine

With CrewAI, you create a crew:
