When to use Kling AI Avatar v2 Pro

Updated 2026-10-08

Where this model earns its cost — and where it doesn't.

Kling AI Avatar v2 Pro, from Kuaishou’s Kling Avatar 2.0 line (late 2025), animates a single still image from an audio track. The mouth follows the speech or singing, the head and shoulders move naturally, and the audio you send plays through unchanged. There is no duration setting: the clip runs as long as the audio.

In our own tests it kept a synthetic singer’s identity, lip-synced a Vietnamese vocal with the mouth closing on breaths, and kept the original vocal in the soundtrack. A 13 second clip took about six minutes. Kyma accepts uncompressed PCM WAV audio of at least 5 seconds (WAV PCM only for now).

Billing is per second of the finished clip. You declare your audio’s length as duration_s; Kyma checks the audio before generating, cuts anything longer, and charges the clip’s real length.

Talking-Head Clips

Turns a presenter photo and a voice recording into a speaking clip for explainers, lessons and announcements.

Lip-Synced Singing

Makes a character sing your own song track, keeping the real vocal in the soundtrack.

Any-Language Voiceover

Lip-syncs to the audio itself rather than to a transcript, so the language of the recording does not need to be supported separately.

Character Series

Reuses one still of a character across many clips, each driven by a different line of audio.

Not ideal for: Do not use this model for text-to-video scenes, camera moves, or clips longer than 60 seconds; it animates one face from one image and needs an audio track.

FAQ

Common questions about this model.

How much does Kling AI Avatar v2 Pro cost?

$0.15525 per sec. Per second of generated video. Failed jobs are refunded in full.

How do I use Kling AI Avatar v2 Pro?

Kyma is OpenAI-compatible: point your SDK's base URL at https://kymaapi.com/v1, use your Kyma API key, and set the model to kling-avatar-v2-pro. Signing up is free, but this model needs a top-up: the $0.50 signup credit covers the free tier only.

What do I send?

image_url (the face), audio_url (the speech or song as a PCM WAV file, at least 5 seconds) and duration_s, your audio’s length in seconds rounded up. A prompt is required and steers style and motion.

How long is the clip and what does it cost?

As long as your audio. You are charged per second of the finished clip; duration_s caps the charge, and audio longer than duration_s is cut before generation.

Does it keep my audio?

Yes. The clip plays the audio you sent; the model only animates the face to match it.
