Tencent Yuanbao Integrates Hunyuan Hy4preview: Launches Simultaneously at Home and Abroad, Two-Week Free Trial Begins

On August 28, Tencent Yuanbao (WorkBuddy) officially announced the integration of the latest open-source flagship model of the Hunyuan large model - Hy4preview. This update not only launched simultaneously in domestic and overseas versions, but also brought a wave of sincere limited-time benefits: Hy4preview offers a two-week free trial, and the free usage period for the previous generation Hy3 has been extended by one month until September 30.

For friends who follow AI trends, the name Hy4preview may not be unfamiliar. It is the open-source flagship model launched by Tencent Hunyuan, with a total of 770B parameters, 49B active parameters, and a context length of an astonishing 1M. What does this mean? Simply put, it can handle longer texts and understand more complex tasks, especially suitable for productivity scenarios such as programming, office work, and science that require deep thinking. Currently, Hy4preview has been open-sourced on platforms such as HuggingFace, and is also available on Tencent Cloud TokenHub and OpenRouter.

The simultaneous launch of the domestic and international versions of Yuanbao allows developers to directly call this model in programming and intelligent office workflows. From model release to product deployment, there is almost a seamless connection. This speed indeed makes people feel Tencent's execution in AI applications.

So, why is Tencent so eager to launch a free trial? The logic behind it is not complicated. On the one hand, the free strategy can attract more developers to test the model's capabilities, collect real feedback, and accumulate data for subsequent optimization; on the other hand, extending the free period of Hy3 is also to retain existing users and avoid losing them during the model iteration gap. This approach of "use it first, talk later" is quite pragmatic.

From a broader perspective, this move also continues Tencent Hunyuan's consistent strategy - promoting the popularization of large models through the synergy of open source and product ecosystem. In the past, everyone competed on parameter scale, with hundreds of billions or trillions of parameters, but now the focus of competition is quietly shifting. Productization capabilities and ecosystem service capabilities are the key to determining whether a model can truly land.

For ordinary users, they may be more concerned about: What can this model actually do for me? In fact, the positioning of Hy4preview is very clear - it is a productivity tool. Whether it is writing code, processing documents, or assisting scientific research, it tries to become your right-hand assistant. The integration of Yuanbao makes these capabilities accessible.

Of course, the free trial is only the first step. How Tencent will price it later and how to further optimize the model are worth continuous attention. But at least now, if you are interested in AI programming or intelligent office work, you might as well try Hy4preview and see if it can bring you surprises.
