CrewAI is a framework that lets you create teams of AI agents that work together to complete complex tasks. Each agent in a crew can have its own role, tools, and responsibilities, allowing for clear task delegation and coordination. You can define workflows where agents collaborate, pass information, and make decisions based on their individual strengths. CrewAI is useful for building advanced AI systems like automated research assistants, content creation teams, or customer support agents. It’s flexible, supports integration with APIs and tools, and helps developers manage multi-agent interactions in a structured and scalable way using Python.
