Tencent has released an open-source AI model called Hy4 preview. The company posted the announcement on Hugging Face. The model is built for software engineering, research, and financial analysis. It uses a mixture-of-experts design with 770 billion parameters. Only about 49 billion parameters activate for any single text request. Tencent says this keeps resource use lower while still handling complex work. The company plans to integrate the model into products such as CodeBuddy and WorkBuddy. An early-release version may take longer to answer hard questions and sometimes over-checks its own replies. The launch continues Tencent’s push into AI after earlier models including Hunyuan 3.0.
