Kuaishou Unleashes AI Video Trio: Kling O1 and 2.6 Challenge OpenAI’s Sora

Kuaishou has launched three major AI video models in a three-week blitz. The Kling O1 and Kling Video 2.6 systems were unveiled in December 2025. This move signals a direct challenge to global leaders like OpenAI’s Sora.

The announcements target film, advertising, and social media creators. Kuaishou aims to dominate the AI video creation space. The company’s rapid-fire releases showcase its aggressive R&D pace.

Kling O1: A Unified Editing Powerhouse

The first model, Kling O1, launched on December 1, 2025. It is billed as the world’s first unified multimodal video model. This means it combines generation, editing, and understanding in one tool.

Previously, creators needed separate software for each task. Kling O1 streamlines this into a single workflow. It accepts text, video, images, and specific subjects as input.

The model handles complex commands like removing objects or changing scenes. It maintains character and object consistency across shots. This solves a major pain point in AI video production.

Native Audio Generation Arrives with Kling 2.6

Kuaishou revealed Kling Video 2.6 just two days later on December 3. Its breakthrough feature is native simultaneous audio-visual generation. This creates video with synchronized sound in one step.

Traditional workflows require adding sound in post-production. The new model generates dialogue, sound effects, and music instantly. It supports both Chinese and English voice generation.

Video length extends up to ten seconds. The audio quality matches professional mixing standards. This is a significant leap for rapid content creation.

Strategic Impact on Creative Industries

Kuaishou’s triple release targets multiple sectors simultaneously. Filmmakers gain tools for consistent character scenes. Advertisers can produce narrated videos cheaply and quickly.

Social media creators benefit from a unified editing suite. E-commerce sellers automate product video production. The tools address real-world creator needs directly.

According to Reuters, Kling AI’s revenue exceeded $35 million in Q2 2025. This financial success validates the market’s demand. Kuaishou leverages its experience as a short-video platform giant.

Kuaishou’s AI video offensive demonstrates China’s accelerating innovation in generative AI. The Kling O1 and 2.6 models could redefine global video production workflows if their promised capabilities hold true in widespread use.
