About this app
AngelSlim Hy-MT is a cutting-edge mobile demonstration app developed by Tencent's AI infrastructure team. It showcases the incredible power of heavy model compression, allowing a massive 1.8 Billion parameter Translation Large Language Model (LLM) to run completely offline on a standard Android smartphone.
Core Features:
- Hyper-Compressed Translation: Experience advanced machine translation powered by a specialized model squished down to 1.25-bit / 2-bit quantization with almost zero loss in linguistic capability.
- 100% On-Device & Private: Because the engine runs directly on your phone's processor, your translated text is never sent to a cloud server, making it entirely private and operational without cellular data or Wi-Fi.
- Edge AI Demonstration: Built on top of specialized mobile inference frameworks to squeeze maximum tokens-per-second performance out of your smartphone's hardware.
⚠️ Setup Note: The initial APK download is incredibly small (~7.4MB), but upon launching the application for the first time, it will automatically download a highly optimized ~400MB model file to your local device storage. Please ensure you are on a stable connection for the first startup!
System Requirements
