The abstract should summarise the contents of the paper in short terms, i.e. 150–250 words. In November 2022, OpenAI released ChatGPT, which can interact and dialogue with humans and performs excellently in understanding natural language, scalability, writing, programming, responsiveness, etc. In February 2024, Sora was born (though not yet available to the public), which performs very excellently in text-to-video (T2V), ambient rendering, generating complex scenes, maintaining continuity and many other areas. The research objectives of this study are to explore ChatGPT and Sora’s potential influences on Knowledge Management, mainly focusing on its possible impact on enterprise data visualisation, enriching knowledge management innovations, industry landscape, effectiveness, staffing structure, economic costs, etc. This study mainly adopts an exploratory research method and a functional analysis method. In the future, GAI, represented by ChatGPT and Sora, will potentially influence some enterprises’ KM in various dimensions, such as updating enterprise management philosophies, affecting the enterprise’s strategic planning and goal-setting, reducing knowledge management economic costs, enriching knowledge management innovations, reshaping partial industries landscape, improving knowledge management effectiveness, promoting human-computer interaction, reinventing the staffing structure, modernising the enterprise’s knowledge management system, affecting companies’ traditional organisational structures. Unemployment problems may also be a reality that has to be faced in the aftermath of GAI’s onslaught. However, this study is exploratory and still needs further empirical research and data verification for authenticity in the future.
