Quick start with CrewAI
from crewai import Agent, Task, Crew
researcher = Agent(role="Researcher", goal="Find info")
writer = Agent(role="Writer", goal="Write report")
crew = Crew(agents=[researcher, writer], tasks=[research_task, report_task])
result = crew.kickoff()
How to choose
Start with CrewAI. Move to LangChain when you need more control.
