Timeline (last 90 days)
Kling 4.0's release has made it possible for e-commerce and advertising teams to try it, but before use it is necessary to confirm whether the account provides the required model and whether image input is supported, and both conditions are indispensable.
According to official information, ReelDance will also integrate Kling 4.0, with details available on its model page.
Keyframes and Omni Reference cannot be stacked in the same task, meaning one must choose between "precisely controlling every frame" and "flexibly referencing multiple subject images".
In Kling 4.0 full version, the Keyframes feature only accepts images as keyframe input, supports up to 10 keyframe images per task, and the output duration ranges from 3 to 30 seconds.
Regional differences in AI video generation services usually stem from compliance requirements, compute deployment strategies, or phased rollout plans, and Kling 4.0's full-version features may not yet be available in certain countries or regions.
When verifying Kling 4.0 access, three things need to be checked: the image input entry point, the control items for single-shot camera movement, and the deduction amount displayed before submission.
According to Kling's official quick-start documentation, the full version 4.0 and Flash are two independent paths and cannot be conflated.
Kling 4.0's all-purpose reference feature supports flexible combinations of images, videos, subjects and voice timbres in a single task, up to 15 items in total.
Kling AI has officially launched its new-generation video generation model, Kling 4.0.
Kling 4.0 supports picture output at up to 10-bit HDR specifications.
