Overview
Kling AI 2.6, released on December 3, 2025, introduces simultaneous audio-visual content creation, enabling users to generate videos with synchronized audio including voiceovers, sound effects, and ambient soundscapes in a single workflow. This capability eliminates the traditional two-step process of generating silent video and adding audio in post-production. Kuaishou positions this as a key advancement for the platform, with support for both English and Chinese voice generation. Outputs can reach up to 10 seconds in length, with examples on Kling's site demonstrating 1080p quality.
What's New
Simultaneous Audio-Visual Generation
Kling 2.6 adds the ability to generate visuals and audio concurrently, marking the first integrated audio generation capability in the Kling platform. Users can produce videos with three types of audio in one pass: voiceovers and dialogue, sound effects synchronized with on-screen actions like footsteps or door closures, and ambient audio matching environmental context such as weather or crowds. The system aims to align voice rhythm and on-screen actions, reducing the need for separate audio production workflows.
Bilingual Voice Support
The audio generation system supports both Chinese and English natively. Voice outputs include narration, dialogue, and in select cases singing or rap-style vocals. Currently, voice output supports Chinese and English; prompts submitted in other languages may be auto-translated to English for voice generation, though specific behavior may vary by interface. Users working with languages beyond English and Chinese should verify output language in their chosen platform.
Improved Text Understanding
Kuaishou states that version 2.6 improves text understanding and audio-visual alignment compared to previous releases. The model demonstrates stronger handling of multi-element instructions, such as combining subject insertion with background context changes in a single generation request. This can reduce the number of iterations needed to achieve desired results, though actual performance will vary based on prompt complexity and content type.
Character Consistency and Motion Quality
Kuaishou positions the model for story-driven content with more coherent audio-visual output across scenes. The system aims to maintain stable visual identity across different camera angles and scene transitions in narrative sequences. Motion quality improvements focus on more natural movement and better synchronization with generated audio elements, though consistency can vary based on prompt complexity and scene composition.
Output Specifications
Kling 2.6 supports video outputs up to 10 seconds in length, with some interfaces offering 5-second and 10-second duration presets. Examples on Kling's platform show 1080p outputs, though actual resolution and quality may vary depending on mode, queue priority, and plan tier. The system supports two primary input modes: text-to-audio-visual generation from textual prompts alone, and image-to-audio-visual generation that animates static images with synchronized voice and sound elements.

FAQ
How does audio generation affect credit consumption compared to video-only mode?
Native-audio video generations consume significantly more credits than video-only outputs. One published breakdown shows Standard quality video-only at approximately 15 credits for 5 seconds, while High-quality video with native audio uses approximately 50 credits for 5 seconds. The increased cost reflects the additional computational requirements for audio model inference, voice synthesis, and audio-visual synchronization. Verify current credit rates in your interface, as consumption may vary by quality settings and plan tier.
Can I generate audio in languages other than English and Chinese?
Kling 2.6 natively supports voice generation only in English and Chinese. Prompts submitted in other languages may be auto-translated to English for voice generation, though specific behavior can vary by interface. While this allows multilingual prompt input, the resulting audio output will typically be in English. For projects requiring audio in additional languages, users may need to employ separate voice synthesis tools in post-production or verify language output behavior in their specific platform before committing to production workflows.
What is the maximum video duration I can generate in a single request?
Kling 2.6 supports video generation up to 10 seconds in length. Some interfaces offer preset options of 5 seconds or 10 seconds to match typical social media formats and advertising requirements. For longer content, multiple clips can be generated separately and stitched together using external editing tools, though this approach may sacrifice some of the cross-scene consistency that single-generation clips can maintain.
How does version 2.6 compare to Kling O1 for multimodal editing tasks?
Kling O1, released one day prior to 2.6, focuses on unified generation and editing workflows with pixel-level refinement capabilities and conversational editing commands. Official examples from the O1 launch announcement demonstrate editing capabilities like removing passersby, transitioning day to dusk, or swapping attire through natural language prompts. Version 2.6 specializes in audio-visual synchronization and integrated audio generation. For projects requiring extensive iterative editing and post-generation refinement, O1 provides more comprehensive editing tools. For projects prioritizing rapid production of finished videos with integrated audio, 2.6 offers a more streamlined workflow without separate audio processing steps.
Are there hardware requirements for using Kling AI 2.6?
Kling AI 2.6 operates entirely as a cloud-based service through web and mobile app interfaces. No local hardware requirements exist beyond a modern web browser or compatible mobile device. All video generation and audio synthesis processing occurs on Kuaishou's servers, making the platform accessible regardless of local GPU or compute resources.
