existThe easiest way to understand ChatGPT: introduction and usage tutorialIn this article, we explain what is ChatGPT、How to use it. ChatGPT The name of ChatGPT is a combination of two words, Chat and GPT. Chat is a word that most people are familiar with, which means chat. Since ChatGPT is a chat robot, it is understandable why there is a Chat in its name.
What about GPT? If you have never been involved in the field of AI, you may be unfamiliar with the word GPT. So you may be curious, why does ChatGPT have these three words GPT? And what do these three words GPT mean? Let's find out in this article.
Why is it called GPT?
GPT is the abbreviation of Generative Pre-trained Transformer, which means the generative pre-trained Transformer model (because Transformer is a proper noun, it is not translated into Chinese here). Let's understand what these three words mean one by one.
First, there is G, which stands for Generative in English and means generative in Chinese. This means that this AI model is used to generate new data. There are many different types of AI. In the past, the more common type of AI was recognition AI, such as face recognition unlocking of mobile phones, which is achieved through recognition AI. Generative AI is a more difficult technology than recognition, and it can be used to generate text, pictures and other data.
Next is P, which stands for Pre-trained in English. It means that the AI model is pre-trained. GPT's training is unsupervised at the beginning. In other words, there is no human intervention, no special data annotation, and a large amount of data from the Internet is fed into the model. After unsupervised training, it is fine-tuned by human intervention to make the model's output respond to human preferences.
The last T refers to Transformer. As mentioned above, it is a special term, so it is not translated into Chinese. Transformer is a deep learning model proposed by Google in 2017. This model uses attention as a mechanism to generate predictions. GPT is a model further developed based on this Transformer model.
After understanding Chat and GPT respectively, we can know that ChatGPT, a chatbot, is a generative AI, so it will generate new data; at the same time, because it is pre-trained, it can generate content that conforms to human preferences, making people feel that it is intelligent.
