NiuTrans is a machine translation system. It has a platform, an API, and two open-source translation systems. It is developed by the Natural Language Processing Group at Northeastern University (China).
Translation systems NiuTrans.SMT is an open-source statistical machine translation system jointly developed by the Natural Language Processing Laboratory of Northeastern University and Shenyang Yayi Network Technology Co., Ltd. NiuTrans.NMT is a lightweight and efficient Transformer-based neural machine translation system. It is implemented with pure C++ and it is heavily optimized for fast decoding. The system can run with various systems and devices.
Supported languages As of August 2026, translation is available in 450 languages:
