Tencent Launches "Tencent Hy Translation" App Powered by Open-Source Hy-MT2 Model
Tencent Hunyuan has officially released the "Tencent Hy Translation" app across 12 countries and regions, alongside mini-program, browser plugin, and PC web versions. Powered by Tencent's Hy-MT2 translation model, the app supports translation across 33 languages and 5 Chinese regional dialects, featuring voice, photo, and offline mode support. The launch transforms Tencent's open-source translation model into an accessible consumer application capable of on-device offline processing. By enabling lightweight local model deployment on smartphones, it provides reliable translation in environments with poor or no internet connectivity. Users can download translation models directly to their mobile devices to use all key translation features without active internet signals. The underlying Hy-MT2 model architecture offers improved instruction following, domain-specific accuracy, and practical scenario handling compared to the previous Hy-MT1.5 model.
