BYD has released an OTA update for its second-generation Denza D9 model. The update introduces a new AI-powered intelligent agent called Didi Xia, which offers users five distinct functional upgrades.

The Didi Xia agent supports both split-screen and full-screen modes. It integrates various services, allowing users to play music, watch videos, order food, and book hotels directly through the interface.

The AI Space feature provides voice-activated interactive chat, while the memory function records user preferences, habits, and important tasks after voiceprint registration. Additionally, a navigation agent assists with complex route planning.

The system connects to numerous ecosystem partners, including Qwen and Doubao large language models, Amap, Taobao, Alipay, and various entertainment platforms like iQIYI, Youku, Bilibili, and multiple music streaming services.
