OpenRouter is an AI model aggregator. It gives developers one API key and one OpenAI-compatible API to use more than 500 models from over 80 providers, including OpenAI, Anthropic, Google, Meta and DeepSeek. There is no subscription: you pay for what you use, and some models are free to try.
What is OpenRouter?
OpenRouter makes it easy to switch between AI models without signing up to many different providers. You add credits once, then call any supported model through the same API format.
It routes your requests to providers with the best price and uptime, offers automatic fallbacks if a provider is down, and publishes rankings of which models people use most. There is also a web chat to compare models side by side.
