AI GATEWAY

Every Major LLM, Through One Endpoint

Connect to leading AI models from OpenAI, Anthropic, Google, and more through a single endpoint. Drop-in compatible with the OpenAI SDK, with automatic failover and price-based routing for reliable, cost-efficient inference.

A Gateway that Unifies LLMs from Many Providers into One API

OpenGate acts as a single-endpoint AI gateway, giving you automatic failover and price-based routing across models from OpenAI, Anthropic, Google, and more. Fully compatible with the OpenAI SDK, so you can adopt it without code changes.

One API, Every Model

Call any leading model from a single endpoint. Works with your existing OpenAI SDK without code changes.

Higher Availability

If one provider degrades or goes down, requests automatically fail over to a healthy alternative, increasing uptime.

Price & Performance

Price-based routing and edge processing optimize inference cost without sacrificing speed.

How It Works

A single endpoint receives your request and, based on real-time provider health and price, routes it through a smart routing layer to the best provider — failing over automatically if one is unavailable.

Routed to the Best Available Provider

OpenGate tracks response times, error rates, and availability across every provider in real time, and by default load-balances requests across the top available providers, prioritizing price. You can also favor throughput or pin specific providers per request.

01
ROUTING

Skip Unhealthy Providers

Exclude any provider that has seen a significant outage in the last 30 seconds to ensure stability.

02
PRICE

Price-Weighted Selection

Among stable providers, select one weighted toward lower cost — by inverse square of price — to optimize spend.

03
FALLBACK

Automatic Fallbacks

Keep the remaining providers as automatic fallbacks to maximize uptime.
