GPT4 refers to the test based on artificial intelligence, developed by Google's Intelligent Robot System (GPT), which can help candidates evaluate their skills and knowledge. The purpose of GPT4 test is to help candidates evaluate their ability and knowledge level to complete tasks in a limited time.

GPT-4 is the next generation natural language processing model of OpenAI project, and it is expected to become the largest natural language processing model at present. GPT-4 is expected to further improve natural language processing. GPT is the abbreviation of "generative pre-training converter" and is a deep learning model.

GPT-4 is an artificial intelligence language model, which has not been officially released. Because of its high technical content and commercial value, its purchase method may be limited to some extent.

The full name of GPT-4 is generative pre-training transformer 4, which is a deep learning model based on transformer and uses pre-training and fine-tuning techniques.

GPT-4 refers to the fourth generation of generative pre-training Transformers 4, which is the frontier technology in the field of artificial intelligence and has not been officially released yet.

GPT4 is a multimodal model, that is, it can accept images and texts as input and output texts; GPT5 can only accept text as input and output text.
