Core Architecture

CrewAI uses a hierarchical, role-based multi-agent layout. It structures agent cooperation via 'Crews' which consist of 'Agents' (with defined backstories, roles, goals, and LLM providers) executing sequential or consensual 'Tasks'. Communication is managed by a central manager agent or standard consensus loops, allowing agents to hand off task artifacts asynchronously.

How to Use & Configuration

code_example.pypython
from crewai import Agent, Task, Crew, Process

researcher = Agent(
    role="Tech Researcher",
    goal="Discover current AI models",
    backstory="Curious analyst with deep ML knowledge",
    verbose=True
)

research_task = Task(
    description="Analyze 10 AI frameworks in 2026",
    expected_output="Detailed Markdown Report",
    agent=researcher
)

crew = Crew(
    agents=[researcher],
    tasks=[research_task],
    process=Process.sequential
)
result = crew.kickoff()
