Kling 4 Review: Features, Release Timeline, and How to Use Kling 3 on Templix Right Now

Kuaishou announced Kling 4 as the newest generation of the Kling AI video generation line, positioned as a major upgrade over Kling 3 across resolution, audio, clip length, keyframes, and reference input capacity. The launch pattern is unusual: initial availability sits behind Kling AI's own Ultra subscription tier only, a faster lower-cost Kling 4.0 Flash version entered early access at the end of September, and a full public launch is planned for October 2026. The API has not been released yet, which means third-party AI video platforms cannot offer Kling 4 in their catalogs until Kuaishou publishes the developer access.

For creators using Templix, this creates a specific practical situation. Kling 3 is available now in the Templix video model catalog and covers the vast majority of what most creators actually need for character-driven video, cinematic scenes, and multi-shot sequences. Kling 4 will presumably arrive on Templix and other third-party platforms once the API is public, but the timing depends on Kuaishou rather than any specific platform's roadmap. This guide covers what Kling 4 brings to the table based on the official announcement, how it compares against Kling 3, and how creators can get strong results from Kling 3 on Templix in the meantime.

What Kling 4 Is

Kling 4 is Kuaishou's next-generation video generation model, developed as the direct successor to Kling 3 in the same architectural family. The model generates video from text prompts, image references, and video references, with native audio generation and support for both a full standard version (Kling 4.0) and a faster lower-cost version (Kling 4.0 Flash). Kuaishou describes visual realism, camera control, lip sync, in-frame text rendering, and longer, more complete narratives as the specific areas targeted for improvement over Kling 3.

Kling 4 Release Timeline and Availability

The rollout has three distinct phases based on the official Kling AI announcement.

Currently available (limited): Kling 4.0 is live on Kling AI's own platform for Ultra tier subscribers only. Kling 4.0 Flash has been in early access since September 28. Neither version is included in Kling AI's free tier or lower paid plans.

October 2026: Kling AI has announced a full public launch of Kling 4.0 for October 2026, expanding availability beyond the Ultra tier.

API status: The Kling 4 API has not been released yet. This is the specific reason no third-party AI video platform (including Templix) currently offers Kling 4 in its catalog. Third-party access opens once Kuaishou publishes the API.

For creators using Templix, this means Kling 3 remains the current Kling option in the catalog. When Kling 4 becomes available through the API is entirely dependent on Kuaishou's release schedule rather than any specific platform's decision.

Kling 4.0 vs Kling 4.0 Flash: Two Versions

Kling 4 launches in two distinct configurations serving different production needs.

The two-version structure follows the pattern most current AI video platforms are converging on: a premium tier for finished output and a faster cheaper tier for iteration work during the exploration phase of production. Creators typically use the fast tier to test many prompt variations quickly, then rerun the winning prompts on the standard tier for final delivery. Kling 4.0 Flash serves that first role for the Kling 4 family, while Kling 4.0 covers the second.

Kling 4 Key Features from the Official Announcement

Kuaishou's Kling 4 announcement covers several specific capability areas worth understanding for creators planning around the upcoming release.

Output resolution up to 4K: Kling 4.0 generates at 720p, 1080p, and 4K, with 10-bit HDR available at the two higher resolutions. Kling 4.0 Flash tops out at 720p. Ultrawide 21:9 aspect ratio is supported for cinematic delivery formats.

10-bit HDR at 1080p and 4K: 10-bit colour depth captures four times as many brightness levels per colour channel as standard 8-bit output, producing smoother gradients and less visible banding in gradient-heavy areas like skies, shadows, and skin tones. HDR output needs an HDR-capable display and platform to be viewed at its best, but the additional colour range also gives more headroom for post-production colour grading.

Stereo audio generation: Kling 4.0 generates two-channel stereo audio alongside the video rather than a single mono track. Directional audio (movement, ambience, effects positioned in the left or right channel) makes generated scenes feel more spatially natural than mono output.

Lip sync and multi-language support: Kling AI states lip sync accuracy improves in Kling 4, with speech supported across Chinese, English, Japanese, Korean, Spanish, Portuguese, German, French, and Indonesian, plus regional dialects and accents.

Longer single-generation clips: Kling 4.0 produces clips of 3 to 30 seconds in a single generation, and Kling 4.0 Flash produces clips up to 20 seconds. A video extension feature listed as coming soon will chain generations to extend clips up to 2 minutes through multiple extension passes.

Up to 15 reference inputs per generation: A single generation can use up to 10 reference images, 5 reference videos totaling 30 seconds combined, and 7 subject references, plus voice references for audio work. Supported reference types include subject images, motion references, infographics, game UI, keyframes, wireframes, and depth-map videos, giving creators granular control over both what appears in the shot and how it moves.

Up to 10 keyframes plus first-and-last-frame generation: Kling 4 supports up to 10 keyframes within a single generation alongside first-and-last-frame anchoring, letting creators set specific moments in a clip and let the model fill in the motion between them. This provides more precise pacing and composition control than prompting alone.

Camera control improvements: Push-ins, pull-outs, pans, tracking shots, and orbiting camera moves are described as more natural and stable in Kling 4, with support for more complex movement sequences.

Prompt length up to 8,000 tokens: Text prompts can extend up to 8,000 tokens, providing meaningfully more room for detailed direction than most current video models allow.

Kling 4 vs Kling 3 on Paper

Kling 4 extends Kling 3 across most measurable specifications based on the announced feature set.

Kling 3 on Templix Right Now

While Kling 4 access sits behind Kling AI's Ultra tier, Kling 3 covers most practical creator use cases and is available in the Templix video model catalog under the standard subscription. Kling 3 handles character-driven scenes with strong motion continuity, cinematic shot composition, multi-shot sequences with visual logic held across cuts, and native lip sync that reads naturally on dialogue content.

For most working creator projects (short-form social content, product ads, character-driven story series, cinematic hero shots, video content requiring recurring subjects across generations), Kling 3 delivers results that meet or exceed what earlier video model generations required expensive post-production to achieve. The specific advantages Kling 4 adds (longer single-generation clips, stereo audio, 10-bit HDR) matter most for creators producing premium finished deliverables at scale. For iteration work, testing, and the bulk of standard creative production, Kling 3 remains genuinely capable.

For creators building character-driven video series where the same subject needs to appear across many generated scenes, our

character consistency guide covers the reference-locking techniques and structured prompting patterns that hold identity stable across generations regardless of which specific Kling version runs the generation.

For creators needing motion transfer from a reference clip onto generated content, the Templix Motion Control app applies specific movement patterns onto generated characters, adding another layer of creative control to what Kling 3 delivers on its own.

What to Expect for Kling 4 on Templix

Kling 4 will presumably arrive in the Templix catalog once Kuaishou publishes the API. Exactly when that happens depends on Kuaishou rather than any specific third-party platform. Creators wanting to prepare for Kling 4 now can take several practical steps that will pay off regardless of exact timing.

Build structured prompt discipline on Kling 3: The prompt techniques that produce strong output on Kling 3 (specific named cinematography vocabulary, explicit subject description, deliberate lighting specification) transfer directly to Kling 4 when it becomes available. Practicing the discipline on the current model builds skills that compound rather than needing to be relearned.

Assemble reference libraries: Kling 4's 15-asset reference capacity is meaningfully larger than most current models allow. Building organised reference sets (subject images, motion clips, style references, wardrobe references) now means being ready to use Kling 4's full reference capacity from day one whenever access opens.

Plan longer clips around keyframes: With up to 10 keyframes supported, Kling 4 lets creators plan specific moments in a clip in advance rather than relying on the model to find them. Story planning around specific moment beats produces meaningfully more coherent output than open-ended prompting on longer clips.

Explore image models for reference generation: High-quality reference images produce meaningfully better video output than casual reference selections. The Templix image generation catalog covers 6+ image models including Nano Banana 2, Nano Banana Pro, GPT Image 2, GPT Image 2.5, Flux 2 Pro, and Ideogram v4 that can produce reference imagery specifically designed for downstream video generation work.

Templix also carries a broader catalog of 40+ video models across 10+ model families including MiniMax H3, Google Veo 3.1, Seedance, and other leading video generation options, so creators have many alternatives while Kling 4 access remains limited to Kling AI's own platform.

What are the main differences between Kling 4 and Kling 3?

Based on the official announcement, Kling 4 extends Kling 3 across most measurable specifications: 10-bit HDR at 1080p and 4K (Kling 3 does not support HDR), maximum clip length of 30 seconds versus 15 seconds on Kling 3, two-channel stereo audio versus mono, up to 10 keyframes versus 2, and up to 15 reference inputs versus 7. Whether these specification improvements translate into meaningfully better creative output for specific project types is something creators will be able to test directly once Kling 4 becomes broadly available.

What is Kling 4.0 Flash?

Kling 4.0 Flash is the faster lower-cost version of Kling 4, designed for iterative work where speed and cost matter more than maximum output fidelity. Flash outputs at 720p (versus 720p, 1080p, and 4K for Kling 4.0) and produces clips up to 20 seconds (versus 30 seconds on Kling 4.0). Creators typically use Flash for testing prompt variations and drafting during exploration, then rerun the winning prompts on the standard Kling 4.0 for final delivery.

Does Kling 4 generate audio?

Yes. Kling 4.0 generates two-channel stereo audio alongside the video, with improved lip sync accuracy across multiple languages including Chinese, English, Japanese, Korean, Spanish, Portuguese, German, French, and Indonesian, plus regional dialects and accents.

How long can Kling 4 videos be?

Kling 4.0 generates clips of 3 to 30 seconds in a single generation, and Kling 4.0 Flash generates clips of 3 to 20 seconds. Kling AI has also mentioned a video extension feature coming soon that will chain generations to extend clips up to 2 minutes through multiple extension passes.

Is Kling 3 still worth using now that Kling 4 exists?

Yes for the projects where it fits, which covers most practical creator use cases. Kling 3 handles character-driven scenes, cinematic shot composition, multi-shot sequences, and native lip sync at strong quality that meets or exceeds what earlier video model generations required expensive post-production to achieve. Kling 4's improvements matter most for creators producing premium finished deliverables at scale. For iteration work, testing, and the bulk of standard creative production, Kling 3 remains genuinely capable and is available on Templix now.

Can I generate video with keyframes on Kling 3?

Yes, though Kling 3 supports fewer keyframes per generation than Kling 4 does. Kling 3 supports 2 keyframes and Kling 4 supports up to 10. Both models allow creators to anchor specific moments in a clip while letting the model fill in the motion between them, giving more precise control over pacing than open-ended prompting alone.
