Summary

A multi-agent support ticket triage system has been developed using LangGraph, designed to automate the classification, routing, and response drafting for incoming support requests. This system addresses the common challenge of manually sifting through support inboxes by employing specialized agents: one for ticket classification, a router for determining the next step, and another for drafting replies. Crucially, urgent cases are automatically escalated to a human. The architecture supports seamless deployment, running locally with Ollama or via a cloud API, utilizing the exact same graph structure. This approach moves beyond single-agent limitations to handle complex, real-world workflows efficiently.

Key takeaway

For AI Engineers building automation solutions for customer support or similar operational workflows, consider adopting a multi-agent architecture with tools like LangGraph. This approach allows you to break down complex tasks into specialized agent roles, ensuring efficient processing, automated response drafting, and critical human oversight for urgent cases. You can deploy these systems flexibly, either locally with Ollama or via cloud APIs, optimizing for your specific infrastructure needs.
