Recently, WeChat’s innovative measures in search functions have attracted widespread attention. According to the latest news, WeChat Souyisou has started grayscale testing to access the DeepSeek R1 model, providing users with a more intelligent AI search experience. This move not only demonstrates WeChat's continuous efforts in technological innovation, but also brings users more convenient and efficient search services.
Relevant Tencent people confirmed that WeChat Souyisou has officially introduced the DeepSeek R1 model for testing on the basis of using the Hunyuan big model to enhance AI search capabilities. Users participating in the grayscale test will be able to use the DeepSeek-R1 full-blood version model for free and enjoy more diversified search services. This testing phase will help the WeChat team collect user feedback and further optimize the search experience.
In the WeChat search page, users who are qualified for grayscale testing will see a "Deep Thinking" option provided by DeepSeek-R1. The addition of this option marks another important breakthrough for WeChat in search technology. Through this function, users can explore and obtain the required information more deeply, improving the accuracy and practicality of searches.

The self-introduction of WeChat AI search shows that this function is based on the in-depth thinking model development of DeepSeek, aiming to connect Tencent ecological content such as WeChat public accounts and authoritative Internet information to help users quickly obtain the knowledge and services they need. In its open source statement, WeChat also expressed its gratitude to the DeepSeek open source company and the DeepSeek open source community for their contributions to large model open source and related research.
It is worth noting that in addition to WeChat Search, many of Tencent’s products are also exploring access to the DeepSeek model. For example, applications such as Tencent Cloud AI Code Assistant and Tencent Yuanbao are considering integrating the functions of DeepSeek. Among them, Tencent Yuanbao can provide users with more stable, real-time, comprehensive and accurate answers by supporting online searches and integrating Tencent ecological information sources such as WeChat public accounts and video accounts.
Tencent emphasized that when integrating information, the AI search function only involves public accounts and other public information on the Internet, and will not use user's personal information and privacy data. This statement aims to ensure that users can fully protect their personal privacy while enjoying intelligent search services. Tencent's move also reflects its sense of responsibility in data security and user privacy protection.
