What is CrewAI?

1 min read Updated

CrewAI is an open-source framework for orchestrating autonomous AI agents as collaborative teams ('crews'), where each agent has a defined role, goal, and set of tools, and they work together to complete complex tasks.

WHY IT MATTERS

CrewAI models agent collaboration the way human teams work. You define agents with roles ('Financial Analyst,' 'Trader,' 'Risk Manager'), assign them tools and goals, and let them collaborate on tasks through a structured process.

The framework supports sequential (one agent after another), hierarchical (a manager delegates to workers), and consensual (agents discuss and agree) process types. This makes it natural to model real-world workflows like investment research → analysis → execution.

For financial applications, CrewAI's role-based structure maps well to organizational hierarchies. A research agent identifies opportunities, an analyst evaluates risk, and a trader executes — each with appropriate tool access and authority levels.

HOW POLICYLAYER USES THIS

CrewAI teams handling financial tasks can use PolicyLayer to enforce per-agent spending limits. The analyst agent might have read-only market access, while the trader agent has controlled execution authority — matching organizational roles to financial permissions.

FREQUENTLY ASKED QUESTIONS

How is CrewAI different from LangGraph?
CrewAI is higher-level and focused on multi-agent collaboration with roles and tasks. LangGraph is lower-level and focused on stateful graph-based workflows. CrewAI is easier to start with; LangGraph offers more control.
Can CrewAI agents use any LLM?
Yes. CrewAI supports OpenAI, Anthropic, Google, and local models through LiteLLM. Different agents in the same crew can use different models.
Is CrewAI production-ready?
CrewAI is increasingly used in production, with enterprise features like CrewAI+ for monitoring and management. However, multi-agent systems inherently add complexity — start with thorough testing.
