Helsinki-NLP/opus-mt-en-zh and Facebook/nllb-200-distilled-600M are two completely different models, and their structures are also completely different.
Helsinki-NLP/opus-mt-en-zh is a machine translation model, mainly composed of an encoder and a decoder. The encoder encodes the input English sentence into a set of vectors, and the decoder takes the vector as input and generates the corresponding Chinese translation result. The model is mainly implemented using deep learning architecture based on recurrent neural network (RNN) and convolutional neural network (CNN).
Facebook/nllb-200-distilled-600M is a pre-trained model for natural language understanding. Its structure is based on the Transformer architecture. It is a multi-layered deep neural network, mainly composed of multiple self-attention layers and feed-forward neural network layers. The goal of this model is to provide pre-trained language understanding capabilities for use as a base model for downstream NLP tasks.
Therefore, the two models are very different in structure and designed for different application scenarios and tasks.
On the same device and in the same language, Helsinki-NLP/opus-mt-en-zh runs faster, more accurately, and takes up less memory.
On T1000, Helsinki-NLP/opus-mt-en-zh processes 153 data. The fastest CPU can complete it is 55s, and the GPU can complete it in about 15s, while the facebook/nllb-200-distilled-600Mcpu runs in about 456s, and the gpu can translate in about 131s. Finish.
