Tencent Hy4 AI Model Takes On Kimi K3 And GLM-5.3: What You Need To Know (AI-generated) A new name has been added to China's AI models. Tencent has now entered the competition with a preview of Hy4, a new open-source AI model that can handle practical tasks such as coding, financial analysis, office work and scientific research. Tencent says Hy4 has been designed to do more than simply perform well on AI benchmarks. The company wants the model to be useful for everyday professional tasks, including software development, data analysis and creating documents. Tencent has compared Hy4 with models from two other major Chinese AI companies, Z.ai and Moonshot AI. In an internal blind test involving 163 experts and 203 engineering tasks, Hy4 received an average score of 2.99 out of 4. Z.ai’s GLM-5.3 scored 2.92, while Moonshot AI’s Kimi K3 recorded 2.94. However, these results should be viewed carefully. The comparison was conducted by Tencent itself and is not an independent benchmark, meaning the results do not necessarily prove that Hy4 is better overall. Hy4 comes with 770 billion total parameters, although around 49 billion parameters are active for an individual request. It can also process more than 1 million tokens of context. This large context window allows the model to work with huge amounts of information during a single interaction. That could be useful when dealing with long documents, large software projects or complex research material. Hy4 is also considerably smaller on paper than Moonshot AI’s Kimi K3, which has been described as a 2.8-trillion-parameter open-weight model. Tencent says Hy4 has been developed with practical use in mind. For programmers, the model can assist with understanding code, planning projects, finding bugs and checking whether software works correctly. The model can also handle financial and data analysis, prepare documents and presentations, and create playable game prototypes from simple instructions. One of the more interesting claims is that Hy4 was involved in its own development. According to Tencent, the model was used to test different training techniques, data strategies and evaluation methods. The results were then used to improve later versions of the training process. Tencent has made Hy4 available as an open-source model. Users can access it through Tencent’s CodeBuddy, WorkBuddy, Yuanbao and ima products, as well as through APIs.
