BYD Rolls Out 'DiDiXia' AI Super Agent to Second-Gen Denza D9 via OTA
BYD has released an over-the-air (OTA) update for the second-generation Denza D9, introducing the 'DiDiXia' super AI agent into its smart cockpit system. The update brings customizable AI companion personas, voiceprint-based memory, complex multi-destination route navigation, and direct integration with lifestyle services like ordering food and booking hotels. This update demonstrates how automakers are embedding large language models and rich third-party app ecosystems directly into vehicle cockpits to turn cars into proactive personal assistants. By integrating AI models from providers like Alibaba Cloud, BYD aims to enhance user experience and maintain a competitive edge in smart automotive technology. DiDiXia uses voiceprint registration to remember driver and passenger preferences, supports split-screen and full-screen layouts, and connects with AI models including Qwen and Doubao. It connects to third-party services such as Amap, Alipay, Taobao, and various media apps while leveraging edge-cloud collaboration and dual-mode reasoning for fast and complex tasks.
## BACKGROUND
Over-the-air (OTA) updates allow modern connected vehicles to receive software upgrades remotely, introducing new features without a trip to the dealership. Smart cockpits increasingly utilize voiceprint recognition—a biometric method identifying individuals by their unique vocal characteristics—to personalize cabin settings and automate tasks.
