About Kling 2.6
Kling VIDEO 2.6 generates 5 or 10 second clips with optional native audio, including dialogue, narration, and sound effects, from text or one image.
Why choose Kling 2.6?
Kling VIDEO 2.6 is Kuaishou's first "native audio" model. Instead of producing silent footage and adding voiceover afterwards, it generates picture and sound in one pass. Kling lists narration, multi-person dialogue, singing or rap, ambient sound, and object or action sound effects as supported audio types, for both text-to-video and image-to-video.
In Wizzx, Kling 2.6 is served through the kling-ai model key with the kling-v2-6 version in professional mode. Choose it when a short clip needs to speak or sound right on the first render; choose Kling v3 when you need any whole-number duration from 3 to 15 seconds.
| Wizzx control | Current behavior |
|---|---|
| Prompt | Required, up to 2,500 characters |
| Generation type | Text to video (default), or image to video with exactly 1 input image |
| End frame | Optional image for the last frame; image-to-video only |
| Duration | 5 seconds (default) or 10 seconds |
| Aspect ratio | 16:9 (default), 9:16, or 1:1 |
| Audio | Off by default; turning it on adds native audio at a higher per-second rate |
| Quality mode | Fixed to professional (pro); standard mode is not offered for this model |
| Negative prompt | Optional, up to 2,500 characters |
Best-fit workflows
- Two-character dialogue scenes: Kling recommends its voice features for two speakers and notes that quality may drop with three or more.
- Talking product or spokesperson shots: animate an approved still with image to video and let the character deliver one or two lines.
- Sound-led social clips: footsteps, rain, crowd noise, or a sizzling pan generated in sync with the action, ready to post without a separate audio pass.
- Short songs or rap moments: Kling lists singing and rap as supported audio and recommends 10 seconds for singing or dialogue.
Prompting approach
Describe the action first, then the line that goes with it. Kling's guide recommends unique, consistent character labels instead of pronouns, for example [Detective, low raspy voice]: "Don't move.", with the spoken text in quotation marks and an emotion or tone tag for each speaker. Use linking words such as "then" or "immediately" to control who speaks when. Speech output is Chinese or English; Kling says other languages are translated to English for the voice. In English lines, write ordinary words in lowercase and keep capitals for acronyms and proper nouns. For image to video, upload a high-resolution image, because output quality depends heavily on the input.
Wizzx scope
Wizzx exposes text to video and image to video with one input image, an optional end frame in image-to-video mode, 5 or 10 seconds, three aspect ratios, and an audio on/off switch. Kling's platform-only features, such as binding named voices with @, voice creation, and Motion Control, are not available through this model key. Audio and duration determine the cost; live rates are shown in the pricing section on this page.

Back to all modelsIntegrate the Kling AI API
Every request is asynchronous: submit the task, keep the task ID, then poll for the result. The body below uses the model's default settings.
- 1
Get a Kling AI API key
Sign in and create a key in the dashboard. Set WIZZX_API_KEY in your server environment; never expose it in browser code.
- 2
Submit a task
Send a POST request to the model endpoint. A successful submission returns data.task_id; keep that ID before polling. Submission is not generation completion.
- 3
Retrieve the result
Replace YOUR_TASK_ID with the returned ID and query /api/v1/task/status. Wait for SUCCEEDED and read the output URLs. Stop on FAILED or REVIEW_REQUIRED; do not automatically resubmit an uncertain task.
