About OpenRouter

OpenRouter is a hosted gateway for AI models. Instead of integrating with each provider separately, developers use one API key and one endpoint to reach models from many vendors, covering text, images, video and audio.

The service routes requests with an eye on price and performance, falls back to other providers when one goes down, and lets organizations set fine-grained data policies so prompts only go to models and providers they trust. The API is compatible with the OpenAI format, and the site offers model browsing, rankings, benchmarks and a chat interface. Credits bought once can be spent on any model or provider.

OpenRouter is a proprietary commercial service with no subscription, working on prepaid credits, and its pricing page lists the details. It is used by individual developers, coding agents and applications that want to compare, switch or combine models easily.
