Tencent Previews Hy4 and Hy4 Flash as WorkBuddy Expands for Global Enterprises

Tencent Cloud used its 2026 Global Digital Ecosystem Summit in Shenzhen on October 30, 2026, to set out its next step in enterprise artificial intelligence: a preview of its upcoming Hy4 model and a smaller, cheaper Hy4 Flash, alongside an international push for its AI office productivity agent, WorkBuddy. The announcement frames AI less as a laboratory breakthrough and more as everyday business software, with models, agents and cloud infrastructure sold together.

The headline numbers in the announcement are about adoption rather than benchmarks. Tencent Cloud said its active overseas customer base has doubled over the past year, while international demand for its AI products and services has grown by triple digits. It now serves customers in more than 150 countries and regions, and said nine out of ten Chinese internet companies expanding globally use Tencent Cloud.

What Hy4 and Hy4 Flash are meant to do

Hy4 is positioned for harder, longer work rather than short answers. Tencent said the general release is coming soon, with enhanced performance on long-horizon and real-world productivity tasks, raising reasoning efficiency and introducing visual understanding for the first time. That combination matters for office work because many business tasks are not single questions: they run across documents, messages and systems, and they need a model to keep track of context over time.

Hy4 Flash is the companion model for cost-sensitive use. Tencent described it as a cost-effective model that carries over Hy4’s visual understanding and agentic capabilities, meaning it is aimed at businesses that want agent-style features without paying for the full model on every task. No price was given in the announcement, so the value of that trade-off will depend on the pricing that accompanies the general release.

Enterprises will be able to access Hy models alongside leading third-party models through Tencent Cloud TokenHub, a unified platform with a single API. Companies can choose models based on performance and cost, and manage access, usage, governance and billing in one place. That approach mirrors a wider industry shift toward model choice: instead of betting on one system, businesses route each task to the model that fits it best, much as Google’s Gemini 4 Carbon targets specialist security and coding work while general models handle broader tasks.

WorkBuddy moves from tasks to everyday workflows

WorkBuddy is the product that turns the models into something employees actually use. Since launching in March, it has handled over nine billion task requests, with adoption spanning more than 50 industries and 50 percent of China’s top 500 enterprises, according to Tencent. Its ecosystem now includes more than 50,000 developers and partners and more than 200,000 skills, bringing AI capabilities into everyday business workflows at scale.

For international enterprises, Tencent is expanding WorkBuddy so it connects with widely used messaging applications and enterprise systems, letting teams complete tasks within the tools they already use. Customers can choose the AI model that best fits each task, and built-in security controls are meant to support enterprise use. Dowson Tong, Senior Executive Vice President of Tencent and CEO of the Cloud and Smart Industries Group, said: “AI is creating new opportunities for businesses, but its real value comes when it can be applied to everyday operations and adopted at scale.”

AI is creating new opportunities for businesses, but its real value comes when it can be applied to everyday operations and adopted at scale.

That everyday-work pitch is also visible in Tencent’s wider international product launches, which include CodeBuddy, WorkBuddy, Miora, the Agent Development Platform, MAGIC AI and Agent Runtime, enabling Chinese and international teams to collaborate on the same AI workbench. In China, Tencent also introduced Buddy One, a cross-application collaboration system that lets WorkBuddy coordinate tasks across Tencent’s office applications and specialized business agents. The pattern is familiar from other workplace AI tools, including AI tools that help small businesses plan content: the technology only saves time when it fits the routine people already follow.

Why Tencent is pushing abroad now

The international expansion is built on local partnerships rather than a single global launch. In Southeast Asia, Tencent Cloud helped Indonesian telecoms operator XLSMART migrate more than 1,000 microservices and is exploring broader cloud and AI collaboration with Telkomsel and Indosat. In Thailand, CP AXTRA is working with Tencent Cloud to modernise operations across supply chain management, finance and other functions. In Hong Kong and Macau, where customers include Hung Fook Tong and Fusion Bank, Tencent Cloud’s business has grown steadily for seven consecutive years.

The same partnership pattern appears elsewhere. In Japan and South Korea, Tencent Cloud works with companies including Kakao, Com2uS, Gokko and Pokekara. In Europe, payments provider iyzico and Eastern European e-commerce platform eMAG have migrated workloads to Tencent Cloud, with ongoing collaboration in big data and AI. In Brazil, Extreme Digital Solutions and Positivo work with Tencent Cloud to deliver PalmAI and other cloud-based solutions to local businesses.

At the summit, Tencent Cloud announced new partnerships with Alsaif Gallery, Hoolive, OmniOps and TruKKer in the Middle East, and with Infosys Solusi Terpadu and Central Retail Digital in other markets. With Central Retail Digital, it is exploring how AI agents can strengthen competitiveness and drive innovation in retail.

The infrastructure behind the pitch

None of that works without capacity, and Tencent pointed to infrastructure growth in 2026 across locations including Frankfurt, Osaka, Riyadh, Malaysia, Mexico and Thailand. Its global infrastructure now spans 25 cloud regions and 70 availability zones, and over the next year it will expand its footprint further across Asia, the Middle East, Europe and the Americas.

Tencent Cloud supports public, dedicated, private and hybrid environments to meet different deployment needs. With Tencent Cloud Enterprise, enterprises can bring the full-stack capabilities of public cloud into environments they control, modernising for cloud and AI-native operations while retaining control over sensitive data and critical workloads. The summit also welcomed the founding cohort of the Tencent Cloud Fellow Program, which brings together technology and industry leaders to exchange expertise and share practical experience in AI adoption.

• Hy4 adds visual understanding for the first time and targets long-horizon, real-world productivity tasks.
• Hy4 Flash carries over Hy4’s visual understanding and agentic capabilities at a lower cost tier.
• WorkBuddy has passed nine billion task requests since its March launch, across more than 50 industries.
• Tencent Cloud’s infrastructure now spans 25 regions and 70 availability zones, with further expansion planned over the next year.
• New partnerships span the Middle East, Southeast Asia and retail, including Alsaif Gallery, TruKKer and Central Retail Digital.

What to Watch Next

What to watch next is only what this announcement already sets up: when the general release of Hy4 actually arrives, since Tencent said only that it is coming soon; what pricing accompanies Hy4 Flash and whether its cost advantage holds up in real enterprise use; whether the doubled overseas customer base keeps growing as the new partnerships in the Middle East, Southeast Asia and retail turn into deployed projects; and whether the planned infrastructure expansion across Asia, the Middle East, Europe and the Americas over the next year keeps pace with the triple-digit growth in international AI demand that Tencent reported. Until the general release lands, Hy4 remains a preview, not a product businesses can yet buy and test for themselves.
