CrewAI
Framework for orchestrating role-playing autonomous AI agents. Enables teams of AI agents to collaborate on complex tasks.
What is CrewAI?
What is CrewAI?
CrewAI is a Python framework for orchestrating teams of role-playing autonomous AI agents. Rather than relying on a single monolithic agent, CrewAI enables developers to define crews of specialized agents — each with a specific role, goal, and set of tools — that collaborate to accomplish complex tasks.
The Crew Mental Model
CrewAI is inspired by how human teams work. You define agents like "Researcher," "Writer," and "Analyst," each with its own LLM, tools, and behavioral instructions. A crew then processes tasks sequentially or in parallel, with agents passing work to each other like a real team.
- Role-based agent definitions with custom backstories
- Sequential and hierarchical task execution modes
- Tool integration via LangChain and custom tools
- Memory and context sharing between agents
Key Features
Define teams of specialized agents with distinct roles, goals, and tools.
Run tasks sequentially, in parallel, or hierarchically based on your workflow.
Agents share context and memory across tasks within a crew execution.
Equip agents with web search, code execution, file I/O, and custom tools.
Works with OpenAI, Anthropic, local models via Ollama, and more.
Who Uses CrewAI?
Deploy a researcher agent to gather data and a writer agent to produce a report.
Orchestrate planner, coder, and reviewer agents to build software collaboratively.
Coordinate agents that scrape, analyze, and summarize competitive intelligence.
Automate multi-step business processes with specialized agents at each step.
