AIGC is called AI-GeneratedContent, which uses artificial intelligence technology to automatically produce content. Specifically, it can be based on artificial intelligence technologies such as generating countermeasure network GAN, generating diffusion model and large-scale pre-training model, find the law through existing data, and generate relevant content through appropriate generalization ability. Using artificial intelligence technology to generate content is considered as a new content creation method after PGC and UGC. In 2022, AIGC developed rapidly, in which the continuous improvement of deep learning model, the promotion of open source model and the exploration of large-scale model for commercialization became the "acceleration" of AIGC development.
