# CPM

|
|
## Overview
|
|
|
|
The CPM model was proposed in [CPM: A Large-scale Generative Chinese Pre-trained Language Model](https://huggingface.co/papers/2012.00413) by Zhengyan Zhang, Xu Han, Hao Zhou, Pei Ke, Yuxian Gu, Deming Ye, Yujia Qin,

The abstract from the paper is the following:
|
|
|
|
*Pre-trained Language Models (PLMs) have proven to be beneficial for various downstream NLP tasks. Recently, GPT-3,
|
|
with 175 billion parameters and 570GB training data, drew a lot of attention due to the capacity of few-shot (even
|
|
zero-shot) learning. However, applying GPT-3 to address Chinese NLP tasks is still challenging, as the training corpus
|
|
of GPT-3 is primarily English, and the parameters are not publicly available. In this technical report, we release the
|
|
Chinese Pre-trained Language Model (CPM) with generative pre-training on large-scale Chinese training data. To the best
|
|
of our knowledge, CPM, with 2.6 billion parameters and 100GB Chinese training data, is the largest Chinese pre-trained
|
|
language model, which could facilitate several downstream Chinese NLP tasks, such as conversation, essay generation,
|
|
cloze test, and language understanding. Extensive experiments demonstrate that CPM achieves strong performance on many
|
|
NLP tasks in the settings of few-shot (even zero-shot) learning.*

<Tip>
|
|
|
|
CPM's architecture is the same as GPT-2, except for tokenization method. Refer to [GPT-2 documentation](gpt2) for
|
|
API reference information.
