This study examines the technological evolution of large models in three domains: text-based models represented by ChatGPT, video models exemplified by Sora, and open-source models represented by DeepSeek. It identifies four essential dimensions of AIGC—cognitive intelligence, technological pathways, general artificial intelligence, and data-generated knowledge paradigms. Based on the autonomous knowledge system of publishing studies, the paper reviews recent progress in how AIGC empowers publishing across five dimensions (VEOMTs): value, element, operation, management, and time-space. Furthermore, it analyzes key challenges in data, algorithms, and computing power, along with the emerging issues of copyright, ethics, and cultural security in the field of publishing studies.
