[Tencent Claims Hy4 Preview Slightly Outperforms GLM-5.3 and Kimi K3 in Internal Blind Tests] According to Bloomberg, Tencent's newly released foundational model, Hy4 Preview, boasts a total parameter count of 770 billion and supports a 1 million token context window. Tencent stated that in internal blind tests conducted by its experts, Hy4 Preview achieved a slight edge over Zhipu's GLM-5.3 and Dark Side of the Moon's Kimi K3. However, in third-party benchmark tests, its performance differed compared to domestic models such as Alibaba's Qwen 3.8 Max. Tencent has made the Hy4 Preview model weights available, allowing developers to access it via the Tencent Cloud platform and integrate it into products like WorkBuddy and chatbots. Officially demonstrated application scenarios include game creation, 3D web design, and accounting compliance workflows. Future versions will further enhance capabilities through additional pre-training and fine-tuning.
