Kling AI
Kling AI is a credit-metered AI video generation platform from Kuaishou, offering text-to-video, image-to-video, motion control, and native audio with lip-sync across model versions from 1.x to 4.0, with a free daily-credit tier limited to watermarked, non-commercial 720p output.
What is Kling AI?
Kling AI is an AI video generation platform developed by Kuaishou. It produces short video clips from text prompts or from uploaded images, and includes a set of motion and editing controls that distinguish it from simpler prompt-to-video tools: Motion Brush for defining movement regions, Motion Control for transferring motion from a reference, start and end frame specification, AI avatars, lip-sync, and multi-element editing for marking and replacing subjects within a clip.
The platform is sold through credit-based subscription tiers rather than per-video or per-second pricing. A free Basic tier provides 66 daily credits, but its outputs carry a watermark, are resolution-capped, and are not licensed for commercial use. Paid plans—Standard, Pro, Premier, and Ultra—remove the watermark, unlock commercial-use rights and 1080p generation, and scale the monthly credit allowance. Kling also sells standalone credit packs that do not expire monthly, but those packs do not replace subscription features such as watermark removal or commercial licensing.
Kling’s model family spans several generations. Kling 3.0 introduced multi-shot generation, native audio with dialogue and lip-sync, and 15-second continuous output. Kling 4.0 extended native clip length to 30 seconds, expanded multi-reference inputs to up to 10 images and 5 video clips, and added dual-channel audio and multi-language lip-sync. Older versions remain in use for certain workflows, but their capabilities—element handling, audio, motion control—differ from the newer models.
How does Kling AI work?
Users generate through the Kling web app or API. On the web, a text prompt or an uploaded image is submitted, and a model version is selected. Kling 3.0 and later support multi-shot generation within a single job, meaning a prompt can be structured as a sequence of shots rather than a single continuous take. Native audio can be included in the generation pass on supported models, with dialogue and lip-sync generated alongside the visual output. On Kling 4.0, a single native clip can run up to 30 seconds, and a generation job can combine multiple image, video, and subject references.
Credit consumption is displayed before submission and varies by resolution, duration, and audio settings. Free-tier generations use daily credits and are watermarked; paid plans draw from the monthly credit pool. When subscription credits are exhausted, generation stops unless the user purchases a standalone credit pack or upgrades. Content moderation runs before and after generation, and rejected prompts or references do not proceed to the rendering stage.
Use Cases
- Generating short social media or marketing clips with native audio and lip-sync from a text or image prompt
- Using Motion Brush or Motion Control to direct specific movement within a generated scene
- Character-driven content requiring consistent identity across shots, using multi-reference inputs on Kling 3.0 or 4.0
- Image-to-video animation with specified start and end frames for controlled transitions
- High-volume iteration on video concepts where per-clip cost matters more than top-end polish
- Evaluating output quality on the free daily credits before committing to a paid plan

Common Limitations
- Free tier is evaluation-only, not production-capable · The free plan provides 66 credits per day, but outputs carry a watermark, are capped at low resolution, and are not licensed for commercial use. Credit expiry is 24 hours, so unused daily credits do not accumulate. The free tier is sufficient to evaluate output quality and prompt behavior; it is not a path to publishable or commercial deliverables.
- Credit consumption is per-second and compounds with resolution and audio · Kling does not publish a single fixed per-second credit rate. Credits are consumed per second of generated video, and the rate depends on resolution and whether native audio is enabled. Kling’s published consumption tables for VIDEO 3.0 reference approximately 6 credits/second at 720p without audio, rising to 12 credits/second at 1080p with native audio. 4K mode is referenced at 30 credits/second. A 5-second 1080p clip with native audio costs roughly 60 credits—twice a 720p silent clip of the same length. Because the interface displays the exact deduction before submission, the effective cost varies by model, feature, and current workflow, making budget estimation dependent on checking the interface each time rather than relying on a stable price list.
- Monthly subscription credits expire; iteration rate determines real output capacity · Subscription credits vanish at the end of each billing cycle and do not roll over. Kling’s own plan-page estimates describe theoretical clip counts (e.g., Pro: ~150 five-second 720p clips), but those figures assume one attempt per finished clip. Real workflows typically require three to five attempts per usable output, so the practical yield is roughly one-third to one-fifth of the stated allowance. A Pro plan’s 150-clip estimate is closer to 30–50 finished clips once iteration is accounted for.
- Content moderation can reject prompts and references before generation · Kling enforces content policies server-side through automated review and human moderation. Prompts, uploaded images, and rendered clips pass through multiple checkpoints. Seemingly benign prompts can trigger automatic rejection, and flagged cases may enter a human-review channel with a waiting period. Repeatedly rewording a blocked prompt to evade the filter is not a supported path; users should adjust the input rather than iterate on phrasing around a policy boundary.
- Model family fragmentation and feature gating by version · Kling 1.x, 2.x, 3.0, and 4.0 coexist with materially different capabilities. Kling 3.0 introduced multi-shot output (up to 6 shots), native audio with lip-sync, and 15-second continuous generation. Kling 4.0 extends native clip length to 30 seconds, expands multi-reference inputs, and adds multi-language lip-sync, but 4K and 1080p 10-bit HDR were still listed as “coming soon” at general rollout. Older versions such as 1.6 and 2.1 handle far fewer elements and lack native audio. Features like Motion Control are not available on every model version. Capabilities are not backward- or forward-portable by default, so the model version and feature set must be matched to the task.

Frequently Asked Questions
Is Kling AI free?
There is a free Basic tier with 66 credits per day, refreshing daily and expiring after 24 hours. Free-tier outputs carry a watermark, are capped at low resolution, and are not licensed for commercial use. Commercial use and watermark removal require a paid plan starting at Standard ($8.80/month renewal, $6.99 first month).
How many credits does a Kling AI video cost?
Kling consumes credits per second of generated video, and the rate depends on resolution and native audio. Kling’s published consumption tables reference approximately 6 credits/second at 720p without audio, rising to 12 credits/second at 1080p with native audio, and 30 credits/second in 4K mode. A 5-second 1080p clip with native audio consumes roughly 60 credits. The exact deduction is displayed in the interface before submission, and Kling states consumption is “subject to the interface display at the time.”
Do Kling AI subscription credits roll over?
No. Subscription credits expire at the end of each billing cycle. Standalone credit packs purchased separately carry a two-year validity and do not reset monthly, but they do not include subscription features such as watermark removal or commercial licensing. For irregular output, topping up a credit pack is often cheaper than upgrading a tier and losing the unused monthly balance.
What is the difference between Kling 3.0 and 4.0?
Kling 3.0 introduced multi-shot generation (up to 6 shots), native audio with dialogue and lip-sync, and 15-second continuous output. Kling 4.0 extends native clip length to 30 seconds, supports up to 10 keyframes and multi-reference inputs combining images, video clips, and subjects, and adds dual-channel stereo and multi-language lip-sync across languages including English, Chinese, Japanese, Korean, Spanish, Portuguese, German, French, and Hindi. Kling 4.0 also adds MCP and CLI access. 4K and 1080p 10-bit HDR output were listed as “coming soon” at the time of Kling 4.0’s general rollout.
Can Kling AI videos be used commercially?
Commercial use is granted on paid plans. The free Basic tier explicitly states that generated content is not for commercial use. Standard and higher plans include a commercial-use license, along with watermark removal and 1080p generation. Users should confirm the current terms on the membership page before relying on outputs for client or revenue-generating work.
