BlueDoAI is a unified API service platform that provides access to multiple Chinese artificial intelligence models through a single API key. The platform integrates text generation, reasoning, coding, image generation, and speech synthesis capabilities from models including DeepSeek, Kimi, Doubao, Zhipu AI, and Tongyi Qianwen (Qwen). It is designed to streamline workflows for office productivity, software development, and content creation by consolidating model selection, API calling, tool usage, billing, and account management into one consistent path. The platform offers a Model Plaza that presents real time information on available models, pricing, and usage status. As of the snapshot date, the Model Plaza includes 7 groups and 22 models covering text conversation, reasoning and coding, image generation, and speech synthesis. Users can review model specifications, pricing, and purchase options directly from the Model Plaza. Account management tasks such as API key generation, top up, balance checks, and usage monitoring are handled through a separate Console interface. BlueDoAI supports an OpenAI compatible API format, allowing developers to integrate the service into existing scripts, applications, and business systems with minimal adaptation. The platform eliminates the need to register and switch between multiple model providers by offering a single entry point for model discovery and a single console for account administration. Users can select appropriate models for specific tasks such as writing, reasoning, coding, image creation, or speech output. Long context windows, caching, and continuous task capabilities are displayed according to each model's public specifications and the platform's real time configuration, which users can verify in the Model Plaza before use.
