OpenRouter is a unified API that provides access to 200+ LLMs from OpenAI, Anthropic, Google, Meta, Mistral, and others through a single OpenAI-compatible endpoint. Developers can switch between models with a single parameter change, compare costs across providers, and fall back automatically when a model is unavailable. OpenRouter is the most flexible way to access and experiment with multiple frontier models.

Best for: Developers building applications that need flexibility to switch between multiple LLMs or compare performance and cost across providers
