From Agentic Loops to Orchestration: Building Reliable Multi-Agent Systems

Building multi-agent systems with traditional LLM-driven loops creates unpredictable latency and behavior that's difficult to trust in production environments. The Orchestrator pattern solves this by separating decision-making from execution: one LLM call to route, deterministic code to execute agents, and another LLM call to synthesize results. This fixed execution model is essential for production systems with side effects like order placement, where reliability and observability are critical.
