Tencent has begun beta testing a new search function in Weixin, China's largest messaging app, powered by DeepSeek. Users can select an "AI Search" option in the search bar, utilizing both DeepSeek and Tencent's Hunyuan foundational model. This feature is exclusive to Weixin and not available on WeChat. The DeepSeek-R1 model, launched on January 20, offers advanced reasoning capabilities at lower training costs compared to AI models from OpenAI, Anthropic, and Google. Approximately 1.3 billion active Weixin users will benefit from this integration for various functions. Users can observe the reasoning process during queries, and DeepSeek-R1 has also been integrated into Tencent's AI chatbot application, Yuanbao. Chinese telecom operators have started using DeepSeek's models, and smartphone manufacturers like Huawei, Oppo, Honor, and Vivo are adopting the DeepSeek-R1 model in their devices.
