$0.2268 / secWhen to use Kling 3 Pro (Audio)
Where this model earns its cost — and where it doesn't.
Created by Kuaishou, this model extends the visual output of Kling 3 Pro by generating synchronized audio tracks alongside video. It accepts text prompts and reference images, returning video and audio outputs in a single request.
Kyma serves this model through an OpenAI-compatible endpoint with automatic failover if a serving path degrades. Prompt caching is supported, billing repeated prompt prefixes at 10% of the standard input rate. New accounts receive a $0.50 free credit to test the endpoint. Every response includes exact billing in the usage.cost field and identifies the executed model via the X-Kyma-Model header.
The model operates on a premium cost tier and generates output at a slower speed. It does not support structured outputs, reasoning chains, or vision analysis tasks. Input is limited to text and images, while output consists exclusively of video and synchronized audio tracks.

Talking head video generation

Product showcase with sound effects
