基于人工智能的传播技术正在深刻改变国际传播生态，大模型技术的推出与应用进一步丰富了国际传播形式。大模型通过充当内容生成的传播主体，直接参与到国际传播过程中，或以接入社交机器人和智能伪造两种智能传播技术形态，间接参与到国际传播过程中。本文首先分析了2023～2024年大模型技术在多模态性能、人机协作模式等方面给国际传播带来的新变化，进而梳理了大模型在新闻领域、视听领域、营销领域的应用以及社交机器人和深度伪造两项代表性技术在大模型技术接入后的应用状态，以及基于大模型的社交机器人、深度伪造技术给国际传播带来的新现象与新特征。最后反思了大模型技术在国际传播中可能引起的社会信任危机问题、偏见和歧视问题以及加剧全球数字不平等问题。
AI-based communication technologies are profoundly transforming the international communication ecosystem，and the introduction and application of large model technologies have further enriched the forms of international communication. Large models serve as content-generating communication entities，directly participating in the international communication process，or indirectly engaging by being integrated into two intelligent communication technology forms—social robots and intelligent fake. This paper first analyzes the new changes brought by large model technology to international communication in terms of multi-modal performance and human-computer collaboration models from 2023 to 2024. It then outlines the application status of large models in the fields of news，audiovisual media，marketing，as well as the representative technologies of social robots and deep fakes after the integration of large models. Additionally，it discusses the new phenomena and characteristics that social robots and deep fake technologies based on large models have introduced to international communication. Finally，the paper reflects on the potential issues that large model technologies might cause in international communication，such as social trust crises，biases and discrimination，and the exacerbation of global digital inequality.
