Kling 4.0 Is Available on kling-4.ai
Kling 4.0 is connected through APIMart as kling-v4. See verified website access, supported settings and paid-credit requirements.
Updated October 23, 2026. Real Kling 4.0 (kling-v4) is connected on this website through APIMart. Text, first-frame and ordered-keyframe production tests have completed successfully. This is our website-access update, not a claim about the publisher’s official launch date.
Correction: Earlier versions of this page described Seedance-backed options as Kling 4.0 and Flash. Those labels were incorrect. Seedance models now keep their own names; the newly connected kling-v4 is a separate model. Old tasks retain their original model and history.

Omni accepts up to 10 images, five videos totaling no more than 30 seconds, and three audio clips of 5–30 seconds, with 15 references in total. Edit uses one 3–30 second source video and optional images. Extend adds 3–30 seconds to one source video, with an optional last frame. Flash, 4K, 120-second generation, Elements and Kling Image 4.0 are not integrated.
The supplier model page describes additional modes. Our website only offers the controls above. The legacy public API does not accept kling-v4; website generation and API availability are separate.
Credits and verification
The minimum Kling 4.0 quote is 85 paid credits for 720p, 3 seconds. Free rewards cannot fund this model under current cost limits. Review pricing and the complete quote before submitting. Each Kling 4.0 submission creates one video. To make another variation, review the settings and quote and submit a new task. A membership does not add a multiple-output control to this Kling 4.0 integration.
Production verification covered three short 720p tasks, playback, downloads and one-time deductions. Other resolutions and longer durations were validated through parameters and quotes, not an exhaustive paid-generation test. Gallery inspiration is not verified Kling 4.0 output. See the Kling 4.0 guide.
