What is Ziyue Translation 2.0
Ziyue Translation 2.0 is the latest translation large model launched by NetEase Youdao. The model has undergone systematic upgrades in three key dimensions: data, algorithms, and evaluation, achieving a qualitative leap in translation quality, efficiency, and robustness. At the data level, Youdao collected and cleaned tens of millions of high-quality translation data, covering multiple fields such as academia, news, and healthcare, with fine-grained annotations by professionals, providing rich and accurate data resources for model training. In terms of algorithms, based on the Ziyue Education Large Model, secondary pre-training was conducted, combined with large model distillation, fusion technology, and Online DPO technology, significantly improving translation accuracy and fluency while avoiding the "catastrophic forgetting" problem common in large models.
