OpenRouter — Technical Overview
The Unified Interface For Every Model
OpenRouter is an open-source API gateway that exposes a single, OpenAI-compatible REST endpoint for routing inference requests across 500+ models from 80+ providers — including Anthropic, OpenAI, Google, and ElevenLabs.
Architecture Highlights
- OpenAI-compatible API: Drop-in replacement for existing OpenAI SDK integrations; swap the base URL and key to gain access to the full model catalogue.
- Provider fallback & high availability: Configurable routing logic automatically retries failed requests across providers, minimising downtime.
- Fine-grained routing controls: Custom data policies, provider preferences, and model selection rules can be set per-request or at the account level.
- Edge infrastructure: Requests are served from edge nodes for reduced latency globally.
- Integrations: First-class support for Vercel AI SDK, Replit, Cline, and ElevenLabs.
