DeepSeek is a Chinese-developed AI platform that integrates with digital human technologies across various sectors, including livestreaming, education, government services, e-commerce, and entertainment. It enables users to create, animate, and deploy AI digital humans for personalized content production, such as voiceovers, short videos, customer service, and virtual teaching. DeepSeek supports functions like natural language generation, emotional expression, lip-syncing, and facial animation, and is used in conjunction with platforms like YouYan (youyan3d.com), JiMeng (jimeng.jianying.com), and MiAi apps to reduce production costs and lower technical barriers. Chinese institutions and local governments have implemented DeepSeek-powered digital humans in smart city initiatives, administrative assistance, public service delivery, and interactive exhibitions. Commercial applications include 24/7 AI livestream hosts and brand avatars, while educational and civic deployments showcase its adaptability to custom training, consultation, and engagement tasks.
