Tencent released Hy-MT2, a family of multilingual translation models in three sizes (1.8B, 7B, 30B-A3B MoE) supporting 33 languages, with paper, GitHub repo, and HuggingFace weights all published May 21. The 7B and 30B models outperform DeepSeek-V4-Pro and Kimi K2.6 in fast-thinking translation mode. The 1.8B model compresses to just 440MB via AngelSlim 1.25-bit extreme quantization with 1.5x inference speedup, making it a strong on-device translation option.
