What Is ChatGPT 4?

ChatGPT is a chatbot program officially released on November 30, 2022, by OpenAI. It is powered by AI technology and can generate natural responses based on the knowledge and data collected during the pre-training phase and interact with the user based on the context of the chat content.

ChatGPT has been previously architected based on the Transformer neural network, also known as the GPT 3.5 model, but the model has many flaws. So on March 23, OpenAI formally created the GPT 4.

GPT-4 is a multimodal model with more extensive pre-training, supporting both image and text inputs, capable of text outputs, and exhibiting graph comprehension. Additionally, it demonstrates improved learning in specialized fields.

ChatGPT-4, which is architected based on GPT 4, became the most advanced publicly available language model(Before the release of GPT-4o). It has extremely fast response speed, strong creativity and reasoning, and a certain level of cognition. Compared to its predecessor, GPT 3.5, which could only tell you the answer in a rigid way, ChatGPT-4 is still not as good as a real human being, but it can provide you with professional and high-academic level answers. ChatGPT-4 can reason more flexibly and creatively, and deal with more subtle requirements, such as composing a song, writing a script according to the user's style, etc.

Although ChatGPT-4 is not a perfect AI language model, it has become a shining star in the age of artificial intelligence.
