BYD Launches Didi Xia AI Super Agent, Debuting in Denza N8L EV
BYD has launched Didi Xia, which it calls the auto industry's first AI super agent. The system debuts in the Denza N8L EV, with OTA updates planned for several other Denza models.
Yang Dongsheng, senior vice president of BYD Group and president of its Automotive New Technology Research Institute, attended the launch and gave a technical explanation of Didi Xia.
BYD said Didi Xia is built on its Xuanji Architecture 2.0, which integrates cockpit, driving and electric systems. The system upgrades the smart cockpit into an AI OS and supports device-cloud collaboration. On-device vehicle controls respond immediately for small tasks, while the cloud handles deeper reasoning for more complex requests, according to the company. It also has a multimodal perception system that can hear, see and feel, as well as an on-demand tool system, a reusable skills system and a memory system intended to understand the user better over time. BYD said the system is paired with an open ecosystem.
BYD positions Didi Xia as different from traditional in-car assistants, saying it can handle multiple scenarios, hold natural and deep conversations, and serve as a more capable in-car agent. The company describes its capabilities in three broad areas: ecosystem integration, task execution and conversation.
On ecosystem integration, BYD said it has built an open platform for ecosystem intelligent agents that supports A2A and MCP standard protocols. Global third-party AI agents and developers can connect to BYD's agent ecosystem to build an in-car agent alliance, according to the company.
At launch, BYD said Didi Xia had connected with more than ten ecosystem partner agents, the largest number in the industry, and described it as an alliance leader in the automotive ecosystem. Among the first industry-specific agents were Fliggy for hotels, Amap for navigation, COLMO for car-home connectivity, Taobao Flash Purchase for food delivery, Ximalaya for audiobooks, QQ Music, Kugou Music, Kuwo Music and NetEase Cloud Music for music, Yuan Shen Xiao Ju for short dramas, Alipay Abao for life services, and iQIYI, Youku and Bilibili for film and television. BYD also said it worked with Doubao and Qwen large models to create chat agents. The partners cover travel, entertainment, life services and AI large models, the company said.
On task execution, BYD said Didi Xia can control in-car settings and functions with a single voice command. When users issue multiple requests at once, it can break them down and execute them step by step to provide what the company describes as an optimal plan.
On conversation, BYD said Didi Xia is not a passive tool but a partner that can understand the user. It comes with personas that can be switched, including a considerate default mode and a sarcastic mode. A voiceprint registration triggered by the phrase 'Hello Denza, let's get to know each other' starts a dedicated memory, according to the company.
The Denza N8L pure electric model is the first to carry Didi Xia. BYD said the second-generation Denza D9, Denza N8L fast-charging version, all-new Denza Z9GT and Denza N9 fast-charging version will also begin OTA rollouts in succession. The company said the move is intended to bring the smart technology experience to users without waiting.
BYD said traditional luxury is defined by a logo, while new luxury is defined by technology, and that Didi Xia is intended to bring a warmer and better AI-powered mobility experience to elite families.
