Chinese technology company Tencent has begun the international rollout of its Hy3 foundation model as it seeks to help enterprises deploy artificial intelligence applications across multiple platforms and markets.
Hy3 is an open-source large language model designed for reasoning, coding, instruction-following and AI-agent applications. It uses a Mixture-of-Experts architecture, with 295 billion total parameters and 21 billion active parameters, and supports a context window of up to 256,000 tokens.
The model combines fast and more deliberate reasoning processes, which Tencent said could improve performance while controlling the computing costs associated with deploying large AI systems.
Hy3 is available under the commercially friendly Apache 2.0 licence, allowing developers and organisations to download, use and modify it. The model has also been made available through open-source communities including Hugging Face and ModelScope. Tencent officially launched Hy3 on July 6.
Enterprise AI deployment
Hy3 has been integrated into several Tencent products and services, including WorkBuddy and CodeBuddy, as well as the company’s Yuanbao, Marvis and ima platforms.
WorkBuddy allows users to perform workplace tasks using natural-language instructions and switch between AI models depending on the requirements of different workflows.
The Hy3 application programming interface is available through Tencent Cloud TokenHub, a model-as-a-service platform that enables organisations to access and manage multiple large language models through a single interface.
Tencent said the platform’s model-routing and governance capabilities were intended to support multi-model strategies and reduce companies’ dependence on a single AI provider.
The company plans to make Hy3 progressively available through international developer platforms including OpenRouter, Hermes, Kilo, Cline, OpenClaw, OpenCode and Cherry Studio.
Tencent Cloud operates a global network spanning 66 availability zones, which the company said would support the secure deployment and scaling of enterprise AI applications.
Focus shifts to business value
The launch comes as governments and companies across the Gulf invest in data centres, cloud computing and sovereign AI infrastructure.
Enterprises are increasingly turning their attention from experimentation towards practical deployment, where challenges can include data quality, governance, operating costs and dependence on individual technology providers.
Tencent is positioning Hy3 as a model that can be integrated into enterprise systems while giving organisations greater control over deployment and model selection.
The international rollout also builds on Tencent Cloud’s Agent Development Platform, which is designed to help companies develop, deploy and govern AI agents at scale.
Tencent has deployed AI across its own businesses, including the Weixin ecosystem, advertising, gaming and customer-service applications. The company said Hy3 had improved the ability of customer-service assistants to interpret incomplete questions and use earlier conversation context to provide more relevant responses.
In gaming, the model has been integrated into an AI assistant for Path of Exile: Advent on Tencent’s WeGame platform, where it is being used to improve responses to player requests and reduce inaccurate answers.
