What is OpenRouter?
OpenRouter is a unified API for AI models that lets you call 600+ models from 80+ providers with one key and the OpenAI API format. More than 250,000 apps use it to generate text, images, video and audio without integrating each provider separately.
What is OpenRouter used for?
It lets developers and companies test, compare and switch models without rewriting code. You create an account, add credits and generate a key; the same balance works with any model. Because it is OpenAI-compatible, moving from the OpenAI or Anthropic SDKs usually means changing only the base URL and model name.
What technical benefits does OpenRouter offer?
- Automatic fallback to another provider when one goes down.
- Auto-routing and preferred provider selection.
- Edge execution for lower latency.
- Data policies so prompts only reach trusted providers.
- Function calling and tool support.
- Public rankings showing real usage of each model.
What does OpenRouter offer teams and enterprises?
You can create team organizations, share credits and bring your own provider keys (BYOK). The enterprise tier adds dedicated support, workload identity federation and signed agreements. There is also an Agent SDK and a Responses API.
Who is OpenRouter for?
Indie developers, AI-native startups and teams that want to compare models or avoid depending on a single provider's uptime. It also suits anyone using tools such as coding assistants that accept any OpenAI-compatible endpoint.

- Pro: hundreds of models through one integration
- Pro: cross-provider fallback for higher uptime
