Low-latency smart routing across multi-cloud models with zero-downtime provider fallback and deterministic A/B splits.
- Fallback chains
- Model aliases
Enterprise LLM Gateway
Text, code, voice, images, and video — with sub-millisecond routing and enterprise guardrails.
import { nRouter } from "@nrouter_ai/sdk"
const client = new nRouter({
model: "gpt-5",
})
const stream = await client.chat.completions.create({
model: "gpt-5",
messages: [
{ role: "system", content: "You are nRouter's support agent." },
{ role: "user", content: "Where is my order #4182?" }
],
stream: true,
})
for await (const chunk of stream) {
process.stdout.write(chunk.choices[0]?.delta?.content || "")
}

Architecture
Every call clears the AI Security layer first: WAF, DDoS shielding, rate limits, and model ACLs. 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.
