Kling AI is a generative artificial intelligence service created and hosted by the Beijing-based technology company Kuaishou. Kling generates videos from natural language descriptions, called prompts. [1]

History

Kling AI was developed by Kuaishou, a Chinese technology company founded in 2011 that operates a popular short video platform. [2] Kuaishou launched the first version of Kling AI in June 2024, making it available for public testing within its video editing app, KuaiYing. [3]

In December 2024, Kuaishou released Kling 1.6, which featured improved video generation capabilities. This was followed by Kling 2.0 in April 2025, and Kling 2.1 in May 2025, which introduced different quality modes for users. [4] [5]

On June 5, 2025, celebrating its first anniversary, Kling launched a referral program. [6] Through it, new users get 50% extra free credits (up to a limit of 5,000 credits) by entering the Kling AI referral code 7BPNSXVCR8FL when purchasing a plan. [7]

Technology

Kling AI uses a diffusion-based transformer architecture (DiT), which has been enhanced by Kuaishou with a self-developed 3D variational autoencoder (VAE) network. This 3D VAE network allows for synchronous spatiotemporal compression, which helps to improve the quality of the generated videos while maintaining training efficiency. [8]

The model also features a computationally efficient, full-attention mechanism that serves as a spatiotemporal modeling module. This allows Kling AI to accurately capture complex motion and details in videos, including fast-moving objects and drastic scene changes. [9]

Model versions

Kling AI has been released in several versions, each with different capabilities and features. The models are available in different modes, including Standard, Pro, and Master, which offer varying levels of resolution, video duration, and creative control. [10]

Reception

Kling AI's content moderation policies have faced criticism. The model operates under strict censorship rules that align with Chinese government regulations, preventing the generation of content related to sensitive topics such as politics, protests, or criticism of the government. [11]

Furthermore, the popularity of Kling AI has attracted malicious actors. In May 2025, a malware campaign was discovered that used fake Kling AI websites and advertisements to distribute infostealer malware to unsuspecting users. [12] [13]
