OpenRouter
A unified API aggregator and interface for comparing and accessing over 300 LLMs.
What is OpenRouter?
OpenRouter (frequently searched as open router or open router ai) is a unified interface and aggregator for large language models. The openrouter ai platform allows developers and users to compare and utilize over 300+ models from more than 50 active providers. Rather than managing dozens of separate API subscriptions, developers can implement the openrouter api to seamlessly query various systems, including both commercial models and openrouter free models. Because of its open design and standard compatibility, it is often utilized to power external tools and platforms like janitor ai.
