Tencent Tests DeepSeek-Powered AI Assistant "Dayuan" on WeCom, Shares Surge
Tencent’s shares jumped more than 5 % on June 24 after Bloomberg reported that the company is piloting a new AI assistant for its enterprise messaging platform, WeCom. The rally lifted the Hang Seng Index by almost 200 points.
The assistant, called Dayuan, is powered by DeepSeek’s latest V4 large‑language model. A social‑media post from Tencent’s head of public relations, Zhang Jun, confirmed that Dayuan has begun rolling out to a limited group of WeCom users. The tool supports natural‑language interaction and is aimed at boosting workplace productivity.
Dayuan can scan internal group chats, emails and calendar entries to help businesses interpret customer feedback and improve engagement. Screenshots shared by Zhang show the assistant can also automate routine tasks such as compiling daily industry briefings and drafting weekly reports.
Tencent’s strategy is to leverage the extensive data already embedded within WeCom, which is tightly integrated with WeChat’s vast consumer network. By using that data, Tencent seeks to differentiate its offering from rival AI productivity tools.
WeCom competes directly with Alibaba’s DingTalk and ByteDance’s Lark in China’s workplace collaboration market. All three platforms act as gateways to their parent companies’ cloud businesses, which are benefiting from surging demand for AI computing resources. Tencent’s advantage lies in WeCom’s deep integration with WeChat, which has more than a billion monthly active users.
WeChat itself is exploring broader integration with AI‑native assistants. The company is working to close the gap with rivals Alibaba and ByteDance in large‑language‑model development and AI adoption, as the sector becomes an increasingly critical battleground for China’s leading technology firms.
DeepSeek, a Hangzhou‑based AI company founded in July 2023, has released a series of open‑weight large‑language models. Its V4 model, which powers Dayuan, is reported to provide performance comparable to other contemporary models while being trained at a fraction of the cost.
Tencent’s move comes amid a broader trend of Chinese technology giants deploying AI assistants in enterprise and consumer products. Earlier this year, Tencent announced a native AI assistant for WeChat, Xiaowei, and has been testing AI agents in other products.
The introduction of Dayuan is expected to strengthen Tencent’s position in the enterprise AI assistant market, where competition is intensifying. Microsoft, Baidu, and other firms are also developing AI agents for business workflows.
At present, Dayuan is in a limited internal test phase. No official launch date has been announced, and the company has not disclosed the size of the user cohort or the scope of the data that will be accessed.
Tencent’s stock performance reflects investor optimism about the potential of AI to drive growth in its messaging and cloud businesses. The company’s market capitalization remains among the largest in China, and its enterprise messaging platform is a key component of its ecosystem.
In the coming weeks, market participants will watch for further details on Dayuan’s capabilities, the scale of its rollout, and any regulatory commentary on data usage within the platform. The outcome of these developments will shape the competitive dynamics of China’s AI‑enabled enterprise services.
Until then, Tencent’s shares continue to trade above the 2025‑level average, and the Hang Seng Index remains buoyed by the company’s perceived AI momentum.
