Tesla China has begun rolling out version 2026.14.13 of its in-car software, formally integrating ByteDance’s Doubao large language model into the Model 3, Model Y, Model S and Model X. The update is being delivered in batches to newly delivered vehicles and some existing cars. Doubao is integrated as a standalone in-car app and provides voice-based interaction. The service offers four voice options and five modes centered on real-time information queries, conversation, storytelling, English practice and debate. Tesla’s release notes say the model can provide real-time information and hold more natural conversations.

Tesla’s voice-assistant setup also assigns Doubao to commands such as navigation, media playback, air-conditioning adjustments and owner-manual queries, while DeepSeek handles broader AI interactions. 21st Century Business Herald https://m.21jingji.com/article/20260731/herald/bf6f3ae1bdd36b17a1dd36236fe277b9.html , in Chinese
