A production AI gateway for every model

An AI gateway sits between your app and the models — one stable API, automatic routing and failover across 470+ models from every major lab.

G0I is the gateway layer for AI infrastructure. Instead of wiring your application directly to each provider, you call G0I once and it handles routing, failover and access to every model.

Why route through a gateway

Resilience — automatic failover keeps requests flowing if an upstream is slow or down.
One stable contract — your code targets one OpenAI-compatible API; models change behind it without code changes.
Scale-ready — built for production workloads, streaming and concurrent traffic.
Full surface — chat, tool calling, vision, image generation and video generation.

Integrate in three steps

1 · Create an accountSign up at g0i.ai and grab an API key in seconds — no card required to start.

2 · Change one linePoint your existing OpenAI SDK at https://g0i.ai/v1. Same request shape, same response shape.

3 · Call any modelSwap the model field to use GPT, Claude, Gemini, Llama, DeepSeek and 470+ others — one key, one bill.

One call, routed for you

curl https://g0i.ai/v1/chat/completions \
  -H "Authorization: Bearer $G0I_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"gpt-5.4","messages":[{"role":"user","content":"Hello"}]}'

Frequently asked questions

What is an AI gateway?
An AI gateway is infrastructure that sits between your application and AI model providers, giving you one stable API plus routing, failover and unified billing.

Does G0I handle failover?
Yes. If an upstream model host is slow or unavailable, G0I automatically fails over so your requests still complete.

Is G0I suitable for production?
Yes — it is built for production workloads with streaming, concurrent traffic and resilient routing.
