Enterprise LLM Gateway
Sub-millisecond LLM gateway with smart routing, AI guardrails, and real-time cost controls — for your teams and your agents.
import { nRouter } from "@nrouter_ai/sdk"
const client = new nRouter({
model: "deepseek-v4-pro",
})
console.log("Running nRouter agent...")
const stream = await client.chat.create({
model: "deepseek-v4-pro",
messages: [
{ role: "user", content: "Explain Tokio SIMD" }
],
stream: true,
})
for await (const chunk of stream) {
process.stdout.write(chunk.content)
}

Architecture
Every call clears the AI Security layer first: WAF, DDoS shielding, rate limits, and per-org budgets. Then your routing policies apply.
Your apps use one nRouter key. We manage the provider credentials.
Platform
Gateway, guardrails, routing, and budgets. One platform for production AI.

Proven at Scale
From high-concurrency live sports to sovereign banking AI, see why leading teams deploy production LLMs on nRouter.
“nRouter handles our peak playoff traffic with automated cross-cloud failover and sub-millisecond overhead. Zero dropped fan requests during game-ending buzzer beaters.”

“With real-time inline PII redaction and sovereign data boundaries, nRouter lets our engineering teams deploy LLMs at national scale while exceeding regulatory audits.”

“Swapping models and setting per-student rate limits took two lines of code. Our unit costs dropped 38% while throughput quadrupled across global learners.”

“The virtual key architecture and pre-call budget reservation completely eliminated runaway LLM spend and unexpected bill shock for our agent fleet.”

“nRouter handles our automated customer service agents with zero-downtime failover between Claude and GPT. Our enterprise SLAs are consistently met at 99.99%.”

“Smart routing across multi-modal embedding models cut our inference costs by 45% while keeping search latency under 5ms worldwide without vendor lock-in.”
