中国媒体APPENDIX 1SummaryIn 2017,AlphaGo defeated Jie Ke,the world champion,in a weiqi chess contest;and in 2022,OpenAl launched ChatGPT.Webelieve that its human-like analytical ability demonstrates a milestone of technological revolution that makes people re-understand Al in terms of "creation"rather than "computation".ChatGPT is a smart Al chatbot built based on the GPT network,which stands for Generative Pre-Trained Transformer.G stands for Generative,the content generation function.Unlike search engines,it generates new text by "single-character-based sequence build-up"rather than merely matching existing content in databases.P refers to Pre-Trained,which means that the model has been trained with certain materials,mainly trained and optimizedthrough two datasets and three models.T stands for Transformer,the underlying deep learning model,which is similar to a smart language bot that receives textinput by users and then automatically understands users'intentions and generates answers based on its learnt knowledge andexperience.ChatGPT adopts a large language model and continuously learn to interact with human through lots of minor training anditeration.GPT-4 was launched in March 2023,and its number of parameters is estimated to reach a trillion.Generative Al cansimulate human's creativity and imagination to some extent based on worldwide large knowledge bases.ChatGPT marked the keysingularity of Al,which enabled it to acquire more than 100mn monthly active users only two months after its launch in November2022.OpenAl,the developer of ChatGPT,was founded in 2015,and has become an industry pioneer;and in China,Baidu launchedits large language model product"ERNIE Bot"as well in March 2023.Risks:Slower-than-expected progress of domestic large-scale model development.5Apr20232
