About Kling
Kling is Kuaishou's flagship video generation family, built for shot-level control: camera moves, subject motion, and consistent physics across a clip. It handles both pure text prompts and image-driven animation, which makes it a common choice for product shots, short-form ads, and previsualization.
Each version stays available after a new one ships, so you can pin a version for reproducibility or move up when quality matters more than cost. v2.1 leads on motion coherence and prompt adherence; v1.6 and below remain useful for high-volume drafts.

Context
About Kling on RunAPI
Kuaishou has shipped video models on a fast cadence since 2024, and Kling sits alongside Veo, Seedance, and Runway as one of the few families delivering reliable 1080p motion at production scale. On RunAPI it runs behind the same task API as every other video model, so switching families is a one-line model change.
Why Use Kling Through RunAPI
Competitive pricing
Aggregated volume, passed through. No subscription, no minimum spend, no per-seat fee.
Automatic failover + webhooks
Requests reroute on provider errors, and completed tasks can be pushed to your webhook instead of polled.
Kling Questions
What can Kling generate?
Text-to-video and image-to-video clips up to 10 seconds, at 720p or 1080p, with camera and motion control.
How long does generation take?
Typically 60–120 seconds for a 5-second clip; 10-second clips take about 2–3 minutes.
What's the difference between versions?
v2.1 has the strongest motion coherence and prompt adherence. Earlier versions are cheaper and faster, and remain available indefinitely.
Can I animate my own image?
Yes. Use the image_to_video task type with an image_url and an optional motion prompt.
How is video billed?
Per second of output video. A 5-second 1080p clip on kling-v2.1 costs $2.15. You are only charged on successful completion.
Do you store my prompts or output?
Outputs are stored for 7 days so you can download them, then deleted. Prompts are not used for training.
