Microsoft Three-Layer LLM Routing Architecture for AI Agents on AKS

Microsoft has launched a reference architecture designed to optimize routing for AI agents on Azure Kubernetes Service (AKS). This architecture addresses three critical decisions: selecting the appropriate model, managing call traffic, and determining which GPU replica will process requests. By integrating the Kubernetes Gateway API Inference Extension for load balancing, agentgateway as an AI proxy, and RouteLLM for semantic routing, Microsoft aims to enhance efficiency in agentic workloads, which can involve numerous LLM calls in a single task. Notably, RouteLLM can achieve approximately 95% of GPT-4's quality while only routing 26% of calls to it, significantly reducing costs and processing delays.
