Commencing on July 31, Tesla China is set to initiate a phased rollout of the 2026.14.13 vehicle software update, encompassing all models with a particular focus on newly delivered vehicles. Post-upgrade, vehicle owners will have the capability to activate the new AI voice assistant, which is built upon the Doubao end-to-end voice interaction framework, through a variety of means. This assistant facilitates a seamless 'voice-to-voice' interaction, guaranteeing minimal latency and fostering natural, fluid dialogues.

In terms of functionality, the Doubao large model is responsible for processing essential commands such as navigation, vehicle control, and accessing the owner's manual. Meanwhile, the DeepSeek model is tailored for casual conversations and information retrieval, with Doubao being restricted from accessing the fundamental vehicle control permissions. By integrating this localized large model, Tesla harnesses Doubao's localized strengths within the Chinese market, signifying a significant leap forward in the intelligence of its vehicle systems.
