AI Model Routing and AI Gateways for Production Agents in September 2026 Production agents rarely need the same model for every step. A classification call, a tool-selection decision, a long-context investigation, and a user-facing final answer have different requirements for accuracy, latency, and cost. Sending all of them to one frontier model is simple, but it is usually expensive, less resilient, and harder to govern. AI model routing solves this by placing a gateway or control plane between your application and model providers such as OpenAI, Anthropic, Google, and open-weight inference services.

This separation is increasingly important for ag...
