Tesla is set to enhance its electric vehicles in China by integrating advanced in-car voice assistant functions powered by AI technologies from DeepSeek and ByteDance's Doubao. This development, confirmed through updated terms of use for Tesla's car voice assistant, will debut in the newly launched Model Y L, featuring these AI models to improve voice command capabilities. The partnership with ByteDance’s Volcano Engine aims to enrich Tesla's smart cockpit experience, enabling drivers to control navigation apps, entertainment systems, cabin temperature, and receive news updates through voice commands. While Tesla vehicles in the US currently use Elon Musk's Grok AI, the adoption of DeepSeek and Doubao in China reflects Tesla’s strategic move to compete in the local market amid intense competition from domestic players. The integration of these AI services highlights Tesla's commitment to leveraging Chinese AI innovations to enhance user experience in its vehicles sold in China.
