AI Agents in Practice — CrewAI v2 and Production Multi-Agent Systems

CrewAI v1 was for prototypes. CrewAI v2 with the Flows API is production-ready. Structured outputs, conditional branching, state management.

What’s New¶

• Flows API: Event-driven orchestration with conditional routing
• Structured outputs: Pydantic models for guaranteed format
• Training: Fine-tune crews based on feedback
• Enterprise: Observability, cost tracking

Production Architecture¶

FastAPI → CrewAI Flow → Redis state → Langfuse tracing → async execution. Scales horizontally.

Case Study¶

Compliance reporting: 4 agents (Collector, Analyzer, Writer, Reviewer). 80% automation of quarterly reports.

Multi-Agent Systems Are Production-Ready¶

With CrewAI v2, you have the tooling for production. Key: clear roles, structured outputs, tracing.
