## Positioning

Kling 3 Pro (Audio) generates video clips with synchronized native audio, including ambient sound and dialogue. Use it when your pipeline requires diegetic soundtracks or talking-head footage without post-production audio syncing.

## About

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.

## Use cases

- **Cinematic clips with ambient sound** — Generate short film scenes that include synchronized environmental audio and background noise.
- **Talking head video generation** — Produce character or spokesperson footage with matching dialogue audio tracks.
- **Product showcase with sound effects** — Create promotional clips where visual actions align with generated sound effects.
- **Animated scene prototyping** — Draft early video concepts with placeholder audio to evaluate pacing and mood.

## Not ideal for

Do not use this model when you only need silent video generation or require fast, low-cost batch processing.

## Pick something else when

- You need silent video at a lower cost → `kling-3-pro`
- You require faster generation speeds for drafts → `seedance-2-fast`, `veo-3-fast`
- You want standard video without audio overhead → `kling-2.5-pro`, `hailuo-02-1080p`
