In February 2024, OpenAI introduced Sora, a video-generation model capable of creating one-minute-long, high-definition videos. However, Kuaishou Technology, a prominent Chinese tech company, has now announced its text-to-video model named Kling, which has quickly gained significant attention in the AI community.
Technological Capabilities of Kling
Kling, developed by Kuaishou’s large language model (LLM) team, can produce 1080p high-definition videos that last up to two minutes, doubling the duration of videos that Sora can generate. This model utilizes advanced 3D face and body reconstruction technology backed by Kuaishou’s proprietary 3D Variational Autoencoder (VAE). This technology enables Kling to create videos with realistic and large-scale motions that simulate real-world physical characteristics, setting a new standard in the text-to-video AI space.
Public Demonstration and Access
On Thursday, Kuaishou released a demo video demonstrating Kling’s capabilities. The model is currently available for testing on an invite-only basis through the Kuaiying app, which is Kuaishou’s video shooting and editing application. AI enthusiasts have shared their creations using Kling on various platforms, with videos showing remarkable accuracy in simulating real-world physics and environments.
Comparison with Other Models
Kling is not the only text-to-video model developed in China. In April, Vidu AI launched a similar model capable of generating 16-second videos at 1080p resolution. Unlike Vidu AI, Kling uses Diffusion Transformer architecture, which enables it to translate textual prompts into vivid, realistic visuals. This architecture is instrumental in enhancing Kling’s ability to produce high-quality, detailed videos.
Advanced Technical Features
One of Kling’s standout features is its advanced 3D face and body reconstruction, which allows for the creation of videos in various aspect ratios through variable resolution training. This technology enables full expression and limb movement from a single full-body photo, providing users with versatile video creation options. Kling supports videos at 30 frames per second (fps), ensuring smooth and lifelike motion sequences.
China’s Rapid Advancement in AI
The development and launch of Kling highlight China’s rapid advancements in AI technology. Chinese companies increasingly focus on creating sophisticated AI models that rival or surpass their Western counterparts. The introduction of Kling is a testament to China’s growing capabilities in AI, particularly in generative video models.

Industry Implications
The competitive landscape of generative AI for video is intensifying. OpenAI’s Sora, announced in mid-February, is expected to be released by the end of the year. However, with models like Kling already available for testing, OpenAI may face significant competition. The advancements demonstrated by Kling suggest that Chinese tech companies are not only catching up but are also pushing the boundaries of what is possible with AI-generated video.
Broader Impact on the Industry
The implications of these advancements extend beyond just technology enthusiasts. According to tech investor and actor Ashton Kutcher, who has access to a beta version of Sora, generative video AI can potentially transform the film and entertainment industry. This technology can democratize high-quality video production, making it accessible to a broader range of creators and industries.
Kling’s introduction marks a significant milestone in the evolution of AI video generation. Its ability to produce longer, high-definition videos with impressive accuracy positions it as a formidable challenger to OpenAI’s Sora. As the AI landscape continues to evolve, innovations like Kling will play a crucial role in global video production and AI technology’s future.
