AI gateways emerge as key control layer, with eight core capabilities to govern production AI stacks

AI gateways are becoming one of the most important control layers in production AI stacks: once multiple models, users, agents, and applications share the same infrastructure, direct model access becomes hard to govern.
The author outlines eight core capabilities a strong AI gateway should provide:
Authentication — verify callers and enforce access before any model or tool is reached;
Model routing — send each request to the right model based on cost, latency, quality, or task complexity;
Rate limiting — control request volume and token usage to protect capacity and prevent runaway spend;
Prompt security — inspect prompts for injection, jailbreaks, unsafe instructions, and policy violations;
PII protection — detect, mask, or redact sensitive data before it crosses security boundaries;
Token tracking — measure usage (post is truncated here; the remaining capabilities are not shown).
