Understand this story
On October 20, 2026, Perplexity published the guide "What Is an AI Gateway?", explaining how an AI gateway uniformly handles routing, cost control, security, and usage monitoring between applications and LLMs. The guide states that its request flow includes authentication, policy enforcement (token limits, budgets, PII redaction), routing by cost, latency, and availability, and failover, and records token counts and latency. The guide also cites a Broadcom VMware benchmark from June 2026 stating that a tuned Envoy AI Gateway adds about 2 milliseconds per request at 224 concurrent users, but that guardrails and semantic caching may add tens to hundreds of milliseconds. The guide is currently reported by Unite.AI, with no further developments yet.

Perplexity Releases AI Gateway Guide: Explaining Routing, Cost Control, and Governance for LLM and Agent Traffic
On October 20, Perplexity released the guide "What Is an AI Gateway?", explaining how an AI gateway uniformly handles routing, cost control, security, and usage monitoring between applications and LLMs. The guide states that its request flow includes authentication, policy enforcement (token limits, budgets, PII redaction), routing and failover based on cost/latency/availability, and logging token counts and latency. The guide cites a Broadcom VMware benchmark from June 2026 stating that a tuned Envoy AI Gateway adds about 2 milliseconds per request at 224 concurrent users, but guardrails and semantic caching may add tens to hundreds of milliseconds.
