Kuaishou, a major Chinese short video and livestreaming platform, has developed a comprehensive ecosystem for digital humans, integrating them into its livestreaming, advertising, and social interaction services. Its 3D digital human livestream solution—supported by the Kuaishou Metaverse Interactive Platform and Kuaishou Virtual Studio (KVS)—enables realistic, automated hosts that can engage viewers, respond to audience emotions, and reduce operational costs for streamers. Key technologies include large language and image models (such as the “Kling” platform), the “Nuwa” digital human toolkit, and full-stack AI capabilities for real-time rendering, animation, and voice synthesis. These tools allow users to generate lifelike avatars, automate livestreams, and scale marketing efforts with AI-driven content. Kuaishou positions digital humans not just as avatars, but as productivity-enhancing virtual agents within its broader AIGC (AI-generated content) strategy.
