kling-v2.1: image generation model

Kling v2.1 is Kuaishou's image-to-video model that animates a start image into smooth motion. Served asynchronously from inside Iran through Hormouz.

Pricing:
$0.5000 / run
Type:
video

Kling v2.1 is a video generation model from the Kling family (Kuaishou). It takes a start image plus a text prompt and produces a short video, animating the still with coherent motion and camera movement.

It is served through Hormouz behind an asynchronous predictions API. Submit a prediction, then poll until the clip is ready. The required inputs are a prompt and a start_image; optional controls include duration (5 or 10 seconds, default 5), a negative_prompt, cfg_scale (default 0.5) and aspect_ratio (16:9, 9:16 or 1:1, default 16:9).

Pricing is a flat $0.5 per run. Hormouz provides stable access to Kling v2.1 from inside Iran, with no foreign credit card or circumvention tooling required.
