What is OpenRouter?

OpenRouter is a model marketplace: a single account and API key that routes your prompts to hundreds of models from OpenAI, Anthropic, Google, Meta, Mistral and dozens of smaller providers. Developers use it to swap models without rewriting integrations, fall back when a provider is down, and chase the best price per token. A built-in chat room lets anyone test models side by side before committing code.

Pricing is transparent — you pay each model's going rate plus a small fee on credit purchases — and many models are free to try. Rankings pages show which models the community actually uses and for what, which is valuable market signal. It is a tool for builders more than casual chatters, but for anyone comparing models seriously, OpenRouter has become the default switchboard.
