Route AI Agents Across Models with NVIDIA NeMo Switchyard | NVIDIA Technical Blog

What this post added

This post introduces NVIDIA NeMo Switchyard, an orchestration layer for agentic AI that enables dynamic routing of workloads across specialized and frontier models. It details how NeMo Switchyard addresses the challenge of selecting the optimal model for each task by considering model capabilities, cost profiles, and infrastructure signals. The post describes the provider-agnostic SDK (libsy), the separation of routing logic from specific model providers, and the architecture that supports stateless or stateful routing. It also outlines different routing algorithms, including tuning-free approaches like LLM classifiers, stage routers, and escalation routers, and discusses the importance of infrastructure for seamless handoffs and observability.
