This paper examines the rise of plugins within the context of interconnected computational platforms and socio-cultural landscapes,focusing particularly on their evolving role as extension tools for large language models such as ChatGPT and WenXin YiYan.By integrating historical perspectives on computing,this analysis approaches plugins through the lenses of software studies and cultural techniques theory.It explores how plugins have emerged as a referential system for both technological innovation and socio-cultural transformation,serving as ontological nodes at the intersection of these domains.In an era where the potential for anyone to become a developer is increasingly feasible,the transition from"proto-media"to"meta-media"provides an opportunity to revisit and redefine the relationship between attributes such as openness,extensibility,and experimentalism in both meta-media and computing.This study delves into plugin development as a micro-practice,assessing its functionality in mediating human experiences.By positioning plugins as a key term in media studies,this paper offers a fresh perspective on the interplay between media and socio-cultural systems,opening new avenues for media practices and theoretical engagement.
