DuerOS X is the world's first AI-native operating system launched by XiaoDu based on Baidu's Wenxin large language model. It completely overturned the traditional human-adapted system model, achieving end-to-end connection between the user's intent and tasks, greatly expanding the boundaries of the operating system. DuerOS X fully applies the Wenxin large language model and, through a model routing architecture, can flexibly dispatch different Wenxin models to solve problems of different difficulty levels, making the process more efficient, accurate, and economical. The ability to store, extract, and understand personalized long-term and short-term memory allows DuerOS X to remember historical content and user personalization preferences more clearly. In addition, the application of multi-modal perception technology gives DuerOS X richer perception capabilities. Whether through voice, text, or expressions, communication with XiaoDu can accurately understand user intent and provide appropriate responses.
