One API, every model

GreatRouter gives you access to 200+ AI models across 15+ providers through a single endpoint. No model picker, no key management.

What developers use it for

Six integration patterns that ship with GreatRouter out of the box.

From sign-up to first request in three steps

A working integration in under fifteen minutes.

01

Get an API key

Sign up for a free GreatRouter account and generate your first API key from the dashboard.

02

Point your code

Swap the base URL to the GreatRouter endpoint. The OpenAI-compatible schema works with existing SDKs and frameworks.

03

Ship with confidence

Send traffic, watch routing decisions, and tune optimization. Observability and per-request cost baked in.

Built for production

The primitives teams need to run AI workloads at scale.

OpenAI-compatible, drop-in

Existing SDKs work without changes. GreatRouter is a transparent layer over 200+ models โ€” no new abstractions to learn.

Edge routing, global latency

Routing decisions happen at the edge close to the user. Provider selection considers region, latency, and current load.

Built for production

Streaming, function calling, batch, file inputs, structured outputs, and per-request observability โ€” production-grade from day one.
