ModelRouter

ModelRouter is an independent third-party OpenAI-compatible AI API gateway for developers and teams testing multiple AI model routes through one familiar API pattern. Start with a first-call smoke test, connect one representative workflow, then compare route behavior, failures, retries, latency, and spend before scaling usage. It is not an official service from OpenAI, Anthropic, Google, DeepSeek, or any model provider.

modelrouter provides unified access to multiple AI models via a single API key, simplifying the process for individuals and businesses. Users can call upon various leading AI models like GPT, Claude, and others without the need to manage multiple accounts or APIs, making it economical and efficient for frequent usage. Users sign up for an account on modelrouter, add balance for usage, and generate an API key. They then replace the Base URL in their client or code to point to modelrouter. The service routes requests to various AI models seamlessly while tracking usage and expenses in real-time. modelrouter is designed for individual developers looking for quick access to AI models, as well as teams that require centralized management of members, quotas, and costs. Its unified approach allows for flexible usage across projects and business applications.
