Kuaishou Kling — China's Short Video AI Giant

The Chinese Company That Challenged Sora With Free Access

No one expected in early 2024 that a Chinese short video platform competing with TikTok would transform within 18 months into the creator of OpenAI’s most important competitor in video generation. But that’s what Kuaishou did with Kling AI: starting with a beta in June 2024, reaching 60 million users by January 2026, surpassing 600 million generated videos, with the company’s stock rising 88% in a single year.

Founding Story: From Chinese TikTok to Global AI Platform

Kuaishou is a Chinese company listed on the Hong Kong Stock Exchange, founded in 2011. It was a traditional competitor to ByteDance (TikTok’s parent company), operating a short video platform called “快手” (Kuaishou) with 400 million daily active users in China.

But when OpenAI launched Sora in February 2024 and shook the video generation world, Kuaishou’s leaders decided to respond directly instead of waiting. The company invested in a specialized AI team that leveraged its vast experience in processing billions of video clips daily — an experience most AI companies born from purely research environments don’t possess.

In June 2024, Kuaishou launched the beta version of Kling AI within its KuaiYing video editing app, then rolled it out globally gradually in the second half of 2024.

Main Products and Models

Technical Architecture

Kling AI relies on a Diffusion-based Transformer architecture optimized with an internally developed 3D Variational Autoencoder (3D VAE) that achieves simultaneous spatiotemporal compression. This enables the model to understand body movement and physical logic more accurately than competitors.

Kling 1.0 → 1.6 (2024)

The initial versions that laid the foundation: video generation from text, 1080p resolution, duration up to two minutes.

Kling 2.0 and 2.1 (April-May 2025)

Significant improvements in image quality and motion consistency, with different quality modes (Standard and Pro).

Kling 2.5 Turbo

An update prioritizing generation speed while maintaining quality — responding to the needs of editors and digital creators.

Kling 2.6 (December 2025)

A qualitative leap: the first model in the Kling series to produce synchronized audio and visuals in a single pass. Resolution up to 1080p at 48 frames per second, 10 seconds duration.

Kling O1 (December 2025)

The company’s most ambitious announcement: “the world’s first unified multimodal generation model.” Integrates generation, editing, and understanding of text, images, and videos into one complete engine, solving the “consistency problem” in characters and scenes across multiple clips.

Kling O1 features:

• Motion Control: Transferring motion from a reference video to another character.
• Motion Brush: Precise control over motion paths of video elements.
• First/Last Frame Control: Precise specification of first and last frames to control scene flow.

Avatar 2.0

Generation of customized high-resolution digital avatars for images or videos for commercial use.

Achievements and Numbers

The speed at which Kling achieved these numbers is exceptionally striking:

• June 2024: Beta launch.
• End of 2024: 1.6 million users and 16 million videos.
• January 2026: 60 million users and over 600 million videos.
• December 2025: Annual revenue run rate of $240 million, double the original 2025 target.
• January 2026: 12 million monthly active users and revenue exceeding the annual target by twofold.
• Kuaishou Stock: Rose 88% during 2025, with additional double-digit growth in early January 2026.

According to Artificial Analysis evaluations in early 2026, Kling ranks first in the ELO index for visual models, ahead of Sora 2 and Veo 3 on several benchmarks.

In the international iOS App Store, Kling entered the top 10 graphics and design apps in America, the United Kingdom, Japan, Australia, and Turkey, and ranks first in Russia and South Korea.

Competition and Challenges

Main Competitors

• OpenAI Sora 2: Enables longer clips (25 seconds vs. 10 seconds for Kling), integrated in ChatGPT with easier experience — but at a much higher price ($200/month for full quality).
• Google Veo 3: Superior in resolution (4K), but limited global availability.
• Runway Gen-4: More integrated into professional post-production environments.

Kling’s Key Competitive Advantage

Price: a genuine free tier with 66 daily credits, and Pro subscription at $37/month compared to over $100 at competitors. This pricing makes it a daily work tool rather than an occasional option.

Challenges:

• Privacy concerns: data is processed on Chinese servers under Chinese law.
• A 2025 security incident where the Kling name was exploited in a malware campaign through fake websites.
• Short video duration (10 seconds) may limit some advanced creative uses.

Future Vision 2026–2027

The direction toward Kling O1 and unified models indicates a clear strategy: moving beyond the “video generation tool” phase to building a “creative engine” that handles complete content from text to final video complete with audio and effects.

The company targets exceeding one billion generated videos and 100 million users by end of 2026 according to analyst estimates. Commercial partnerships with brands and advertising companies represent a new revenue layer being explored.

Analytical Conclusion

Kling AI achieved what seemed difficult: competing with the market leader backed by billions of dollars through a dual strategy of technical quality and competitive pricing. The numbers (60 million users in 19 months, $240 million annual run rate) are not just impressive — they redraw what can be achieved in this sector.

The main risk ahead is not technical but geo-political: amid escalating US-China tech competition, restrictions on Chinese apps may limit its ambitions in Western markets. But to date, the platform is growing and competing, and that alone is an exceptional achievement.
