OpenRouter
The unified interface for every model
OpenRouter presents itself as a single interface to AI models from many providers. Users sign up, buy credits, create an API key and make requests that are compatible with the OpenAI API. The service routes requests across providers, can fall back to another provider when one is unavailable, and offers controls over which models and providers receive prompts. The company states it started in early 2023 as an LLM marketplace and now operates as an AI gateway.
