Kling AI Video Models on Martini
Martini hosts the full Kling lineup — Kling 3 for flagship motion, Kling O3 for video-to-video editing, Kling Avatar for lipsync, plus Kling O1 and Kling Classic for legacy workflows. Together they cover motion fidelity, character refs, and avatar production better than any other single provider on the canvas.
About Kling
Kling — built by Kuaishou, the Chinese short-video platform — is one of the most respected video model families in the market for sheer motion fidelity. Kling 3 is the current flagship, known for camera moves, full-body motion, and cinematic detail that often outperforms Veo and Sora on action-heavy scenes. Kling O3 is the video-to-video and editing variant used for restyling existing footage. Kling Avatar handles lipsync and talking-head video from a single reference image plus audio. Kling O1 and Kling Classic remain available for teams on legacy pipelines.
On Martini the Kling lineup is positioned as the motion specialist. When a clip has a person dancing, a creature moving, or a complex camera arc, Kling 3 is usually the first model to try. Kling O3 is the go-to when you need to take an existing clip and transform its style, costume, or background — it pairs naturally with Runway Aleph for video-to-video work. Kling Avatar is the easiest way to put a custom face onto a voiceover without booking a recording session.
Pricing is metered per generation and shares the Martini wallet, so there's no separate Kuaishou or Kling.ai subscription to manage. Workspace billing handles attribution. Because every Kling model lives on the same canvas as Sora 2, Veo, and Seedance 2, you can route a workflow through whichever provider wins each shot — Kling for motion, Veo for cinematic light, Sora for narrative — without rebuilding anything. Teams that came to Martini for Kling alone usually end up using all four.

Frequently asked questions
How does Kling 3 compare to Sora 2 and Veo?
Kling 3 leads on raw motion fidelity — dance, action, full-body movement. Sora 2 leads on multi-shot narrative and physics. Veo leads on photoreal brand-safe lighting. Most teams use all three on the same canvas.
What is Kling O3 used for?
Kling O3 is the video-to-video and editing variant — restyle existing footage, swap a costume, change a background, or drive generation from a reference image while preserving the original motion.
Does Kling Avatar need a custom voice model?
No. Kling Avatar drives lipsync from any audio file, so you can pair it with ElevenLabs or Fish Audio TTS in the same workflow to generate a full talking-head clip.
Do I need a Kling.ai or Kuaishou account?
No — Martini provides hosted access to every Kling model. You pay with Martini credits and never wire up a separate Kling subscription.
Should I still use Kling O1 or Classic?
Mainly for legacy compatibility. New work should default to Kling 3 for motion and Kling O3 for editing, but O1 and Classic stay available for pipelines built on the older models.
Can I combine Kling Avatar with ElevenLabs in one canvas?
Yes — drop an ElevenLabs audio node, connect it plus a portrait image to a Kling Avatar node, and the model will generate a lipsynced talking-head clip in one workflow.
