What is Kling 4.0?

Kling AI globally launched Kling 4.0 on October 16, 2026 — the latest generation of the video model from Kuaishou's creative platform, which the company says now serves over 100 million users and 50,000 enterprise customers. The headline spec is native 30-second generation in a single pass: double what Kling 3.0 could manage and roughly four times the base clip length of Google's Veo 3.1. For anyone making ads, product demos, or short narrative scenes, longer single-pass clips mean fewer seams and fewer continuity headaches.

Control is the other half of the story. Kling 4.0 supports up to 15 multimodal reference assets and 10 keyframe inputs, with an enhanced Omni Reference system designed to hold character consistency across shots and episodes — moving beyond isolated AI clips toward character-driven storytelling. Motion and complex camera work are also more stable. Agent access runs through Kling MCP, and the model is heading to Adobe Firefly soon, which will put it inside professional post-production workflows.

Who Kling 4.0 Is Best For

Best for: Kling 4.0 works best for video creators, editors, and marketing teams. Standout strengths: 30-second single-pass generation is a real capability lead for narrative video work; reference-and-keyframe control is exactly what brand teams need for consistent characters. The free plan makes it easy to try on real work before paying anything.

Not ideal for: Not the ideal pick where these matter most: kling 4.0 is not included in Unlimited packs and has no free generations — every 4.0 clip spends credits; 10-bit HDR and 4K output are officially labeled coming soon, not available in generations yet.

Key Features

Native 30-second clips in one pass — double Kling 3.0, ~4x Veo 3.1's base length.
Up to 15 multimodal reference assets (images, video, audio) per generation.
10 keyframe inputs for frame-level scene planning and character consistency.
More stable dynamic motion and complex camera movements than prior versions.
Agent access via Kling MCP; availability in Adobe Firefly announced as coming soon.

Pros

30-second single-pass generation is a real capability lead for narrative video work.
Reference-and-keyframe control is exactly what brand teams need for consistent characters.
100M+ users and enterprise adoption mean this is production-grade, not a demo toy.

Cons

Kling 4.0 is not included in Unlimited packs and has no free generations — every 4.0 clip spends credits.
10-bit HDR and 4K output are officially labeled coming soon, not available in generations yet.
Credit costs climb quickly at 1080p: a full 30-second clip uses 450 credits — most of a Standard plan's monthly allowance.

What's New in Kling 4.0

Kling 4.0, launched globally on October 16, 2026, is built around one headline change: native 30-second video in a single generation — double the longest clip Kling 3.0 could produce — at 720p or 1080p, with native stereo audio generated in the same pass rather than added afterwards.

Control tools are the second half of the upgrade. A single generation can take up to 15 multimodal reference assets (images, video and audio) and 10 keyframe inputs, and the enhanced Omni Reference system is designed to keep a character looking like the same person across shots and episodes. Motion stability and complex camera moves are improved over 3.0, agent access runs through Kling MCP, and Adobe Firefly support has been announced. 4K output and 10-bit HDR are officially listed as coming soon, not yet available in generations.

Kling 4.0 Pricing & Credits

Kling 4.0 is sold in credits, and the meter runs per second of video: 10 credits per second at 720p and 15 credits per second at 1080p, with audio included at both resolutions. A 5-second clip therefore costs 50 credits at 720p or 75 credits at 1080p, and a full 30-second 1080p clip costs 450 credits. There are no free Kling 4.0 generations and the model is not part of Kling's Unlimited packs — every 4.0 generation spends credits, and the estimated cost is shown before you generate.

Plan pricing changes often and Kling runs frequent introductory discounts — the rates in this section are the published US prices from late October 2026, so confirm the live figures on kling.ai before buying credits.

Free plan: watermarked output and no commercial rights — and no Kling 4.0 generations.
Standard — $8.80/month (first month $6.99): 660 credits a month, about 44 seconds of 1080p Kling 4.0.
Pro — $32.56/month (first month $25.99): 3,000 credits a month.
Premier — from $80.96/month: 8,000 credits a month, with higher tiers for heavier volume.
Developer API: about $0.16 per second at 720p and $0.24 per second at 1080p on Kling's own API packs.
