YiAI Router is a unified model access service for AI Coding workflows. Compatible with OpenAI and Anthropic SDKs, supporting 400+ models through a single entry point. No workflow migration needed.
Developers switch between Claude Code, Cursor, and other AI Coding tools daily. Each tool has different API format and model requirements. We realized the real need is not another new SDK to learn, but a unified entry point to call all major models while keeping existing tools and workflows unchanged.
We are compatible with OpenAI and Anthropic SDK protocols, allowing developers to call 400+ models using existing SDKs, existing code, and existing tools. Whether Claude Sonnet, GPT-4.1, Gemini 2.5 Pro or DeepSeek R1, all available under a single API Key.
We do not lock you in. Your workflow is yours. YiAI Router simply lets every developer choose the best model for the task at hand. We provide a stable API layer and continuously updated model support, so teams can focus on product and development velocity.
