Kling 4.0 Launches Globally With 30-Second Single-Pass Video and 15-Reference Omni Reference

Kuaishou Technology announced on October 16, 2026 that Kling 4.0, the next major generation of its Kling AI video model, went live globally on October 15. The release pitches the model squarely at professional creators, emphasizing stable motion, longer single-pass clips, and far more granular control over references and keyframes than the Kling 3.0 series.

Details

• Launch date: Kling 4.0 went live on October 15, 2026 and is described as “fully available now” on the Kling AI website, with no regional or tier restrictions listed in the release
• 30-second single pass: native generation of up to 30 seconds in one pass, roughly double the clip length of the previous generation
• Steadier motion: more stable large-scale motion and better continuity in fast action and complex camera moves such as tracking and orbit shots
• Omni Reference: up to 15 references per task — up to 10 images, 5 videos, and 7 subjects. Accepted inputs include subject images, three-view character sheets, grid images, storyboards, wireframes, white-model (untextured 3D) videos, and depth-map videos
• Creative recreation: reuses the pacing, composition, and style of a reference video while swapping in new products, characters, or assets
• 10 keyframes: up to 10 keyframe inputs to control character states, scene changes, and story beats
• Long prompts: prompt input of up to 8,000 tokens
• Output formats: 4K and 1080p output; 10-bit HDR and a 21:9 ultrawide format are listed as “coming soon”
• Video extension: multiple extensions totaling up to two minutes will be supported “soon”
• Agent access: Kling 4.0 is integrated with Kling MCP and Kling CLI, so AI agents can call Omni Reference and keyframe-to-video generation
• API: enterprise and developer API access is planned “soon,” with no date given
• Kling 4.0 Flash: a lighter “Flash” variant for high-volume, speed-oriented content is referenced in a partner quote from Adobe, which says it is coming to Adobe Firefly. Press reports (not the official release) say Kling 4.0 Flash entered limited beta for top-tier annual subscribers on September 28
• Pricing: not disclosed in the release

What happened next

Kling 4.0 arrives as the video generation field reshuffles after OpenAI’s Sora was discontinued, and it directly targets the two things professional users complain about most: clip length and control. A 30-second single pass, 10 keyframes, and 15 mixed references move Kling closer to a storyboard-driven production tool than a one-shot clip generator. The model also lands while Kling is becoming a meaningful business for Kuaishou — Kling AI revenue topped RMB 850 million in Q2 2026 — and while rivals such as ByteDance’s Seedance and Google’s Gemini Omni push their own long-form and editing features. The pieces still marked “soon” — 10-bit HDR, two-minute extensions, and the public API — will determine how quickly Kling 4.0 reaches studio pipelines and third-party platforms.
