A proxy layer between applications and model providers that centralizes cross-cutting concerns: authentication, logging, caching, rate limiting, model routing, failover, and spend controls, one governed door instead of every team calling providers directly.
It became standard architecture once multiple teams shipped AI features. The gateway is where cost attribution, security review, and provider migrations happen without touching application code, giving central governance over spend and access.
