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.
Skip Unhealthy Providers
Exclude any provider that has seen a significant outage in the last 30 seconds to ensure stability.
Price-Weighted Selection
Among stable providers, select one weighted toward lower cost — by inverse square of price — to optimize spend.
Automatic Fallbacks
Keep the remaining providers as automatic fallbacks to maximize uptime.
