CrewAI

Overview

CrewAI is an open-source Python framework for orchestrating several LLM agents as a team. You define agents with a role, a goal and a set of tools, group them into a crew, and describe the tasks to be completed; the framework handles delegation and passing results between them. The role-based metaphor is the appeal — it maps cleanly onto how people already think about dividing work, and it gets a prototype running quickly compared with wiring an agent loop by hand. CrewAI also added Flows for cases where you want deterministic control rather than agents improvising, which is a tacit admission that pure autonomy is unreliable, and a hosted enterprise platform for deployment and monitoring. Be clear-eyed about the limits. Multi-agent systems multiply token spend and failure modes, and a crew that chats among itself can burn a lot of money reaching a mediocre answer. The abstractions are pleasant until you need to do something they didn't anticipate, at which point you fight them. For many tasks a single well-prompted agent is cheaper and more predictable.
