OpenRouter

// about OpenRouter

OpenRouter provides a single OpenAI-compatible API endpoint that routes requests to over 300 models from OpenAI, Anthropic, Google, Meta, Mistral, and dozens of smaller labs. Developers can switch between models with a one-line change, implement automatic fallbacks when a provider has an outage, and compare cost per token across every provider in real time. It's become the standard way to build model-agnostic applications and to access models that aren't otherwise available via direct API.
