Enterprise AI gateways have become critical infrastructure for organizations running multiple LLM providers in production. Five leading solutions are ranked for 2026: Bifrost (Go-based, ultra-low latency, advanced governance), Cloudflare AI Gateway (edge-optimized, ecosystem-tied), Kong AI Gateway (mature RBAC, API-first), LiteLLM (broad compatibility, better for prototyping), and Azure API Management (Microsoft-native governance). Key evaluation criteria include latency overhead, hierarchical cost governance, compliance/audit readiness, agentic AI control via MCP, and integration with quality monitoring systems. The post argues that AI infrastructure—not model selection—is now the primary enterprise differentiator.
