Kling ships fast. In about eighteen months it went from version 1.0 to a whole 3.0 family — and people still search for "kling 2.1" and "kling 1.6" because they're not sure which one they're actually using, or which one they should. This guide lays out every version, what each one changed, what it costs to run, and which Kling model to pick for the job in front of you. Last updated June 2026.
TL;DR — which Kling model should you use?
- Best all-round quality (and 4K): Kling 3.0 — native multimodal, element consistency, multi-shot storytelling.
- Cheapest video: Kling O3 at 15 credits/sec, or Kling Avatar V2 at 10 credits/sec for talking heads.
- Lip-sync + native audio on a budget: Kling 2.6.
- Motion transfer / choreography: Kling 2.6 or 3.0 Motion Control.
- The latest version is Kling 3.0 (Jan 2026). Kling 4.0 is not out yet.

The Kling version timeline
Kuaishou launched the first Kling model in June 2024. Here's how it evolved.
Kling AI version history. Release dates from Kuaishou's official notes; bold entries are live on kling4.co.
Kling 1.6 (December 2024) added the first/last-frame lock — you set the opening and closing frame of a 5-second clip and let the model fill the motion between. The Pro tier pushed longer clips and higher resolution. This is the version a lot of early tutorials were filmed on.
Kling 2.0 Master (April 2025) kept the 720p / 5-second baseline but sharpened the things that make a clip look real: camera movement, lighting, and how closely the output follows your prompt.
Kling 2.1 (May 2025) was mostly an efficiency release — same kind of output, roughly 65% cheaper to generate. It's why "kling 2.1" still gets searched: a lot of people locked in on it as the value option.
Kling 2.5 Turbo (September 2025) cut cost again by about 30% and sped up turnaround.
Kling 2.6 (December 2025) is where the feature set jumped: Motion Control, clips up to 30 seconds, lip-sync, facial expressions and gestures, and native audio generated to match the scene.
Kling 3.0 (January 2026) is the current flagship. It's built on a unified multimodal framework — text, image, and audio in and out — with element consistency (keep a character or object stable across shots), multi-shot storytelling that breaks the old duration ceiling, and 4K output. The 3.0 generation also brings the O3, Omni, Avatar V2, and Motion Control variants.
Kling 4.0 hasn't been released. If you see a "Kling 4.0" generator, it's running an earlier model under the hood — on kling4.co the generator is honest about this and automatically falls back to Kling 3.0 until 4.0 actually ships.
The Kling models you can use on kling4.co today
You don't get every historical version — you get the current generation, which supersedes the old ones. Here's what's live and what each costs in credits (a 5-second clip unless noted; failed generations are never charged).
| Model | Best for | Credit cost |
|---|---|---|
| Kling 3.0 | Flagship quality, 4K, multi-shot | 35/sec (Std, no audio) → 65/sec (4K) |
| Kling 3.0 Omni | Multimodal editing | 45–70/sec |
| Kling O3 | Cheapest video | 15/sec |
| Kling 2.6 | Lip-sync + native audio | 85 (5s) / 150 (5s + audio) |
| Kling Avatar V2 | Talking heads from audio | 10/sec (Std) |
| Motion Control (2.6 / 3.0) | Motion transfer | 10–20/sec |
| Kling O3 Image | Image generation | 5/image |

Which Kling model should you pick?
Match the model to the task instead of defaulting to the newest one — you'll spend a fraction of the credits.
- A quick social clip, lowest cost: Kling O3 (15 credits/sec). For a 5-second clip that's 75 credits.
- A talking-head or spokesperson video: Kling Avatar V2 — drive a face from an audio track at 10 credits/sec. Cheapest way to make someone "speak."
- You need sound and lip-sync but want to keep it cheap: Kling 2.6. A 5-second clip with native audio is 150 credits.
- Your best work — a hero shot, a product video, anything client-facing: Kling 3.0. Use Pro or 4K when detail matters; expect 175–325 credits for 5 seconds.
- Dance, gestures, choreography transferred onto a still image: Motion Control (2.6 is cheaper at 10–15/sec, 3.0 is higher fidelity at 15–20/sec).
- Multi-shot story or multimodal editing: Kling 3.0 / 3.0 Omni.
Kling 3.0 vs 2.6 — the one people actually compare
These are the two current workhorses, so it's worth being specific.
Pick Kling 3.0 when output quality is the priority: it has native multimodal control, element consistency across shots, multi-shot storytelling, and 4K. It's the better choice for anything polished or commercial.
Pick Kling 2.6 when you want native audio and lip-sync without paying flagship rates. At 85 credits for a silent 5-second clip (150 with audio), it's noticeably cheaper than Kling 3.0's 175+ — and for talking, lip-synced content it's often all you need.
Rough rule: 2.6 for talking, lip-synced, budget clips; 3.0 for everything where the picture has to look its best.
What about Kling 4.0?
There's real search interest in "kling 4.0," but no public release yet. Until it ships, anything labeled 4.0 is running an older model. On kling4.co the generator falls back to Kling 3.0 automatically, so you always get the best model that actually exists today — and you'll be able to switch to 4.0 here the moment it launches.

FAQ
What is the latest version of Kling AI?
Kling 3.0, released globally on January 31, 2026. It's the current flagship, with native multimodal input/output, element consistency, multi-shot storytelling, and 4K output. Kling 4.0 has not been released yet.
Which Kling AI model is best?
For overall quality, Kling 3.0. But "best" depends on the task: Kling O3 is best for cheap clips, Avatar V2 for talking heads, Kling 2.6 for affordable lip-sync and native audio, and Motion Control for transferring movement onto an image. Pick by use case, not by version number.
Can I still use Kling 2.1 or older versions?
Kuaishou's app moves users to the current generation, and most third-party platforms (kling4.co included) offer the latest models — Kling 3.0, 2.6, O3, Omni, Avatar V2 and Motion Control — rather than retired versions like 2.0 or 2.1. The newer models are both higher quality and, thanks to the 2.1 and 2.5 efficiency releases, cheaper to run.
What's the difference between Kling 3.0 and 2.6?
Kling 3.0 is the higher-quality flagship: native multimodal control, element consistency, multi-shot storytelling, and 4K. Kling 2.6 is cheaper and centers on lip-sync and native audio. Use 2.6 for talking, budget-friendly clips; use 3.0 when the output has to look its best.
When is Kling 4.0 coming out?
There's no official release date yet. On kling4.co you can hold your spot — the generator currently falls back to Kling 3.0 and will switch to 4.0 as soon as it's available.
How much do Kling models cost?
From 5 credits per image and 10 credits/sec for video (Avatar V2), up to 65 credits/sec for Kling 3.0 in 4K. A 5-second clip ranges from about 50 credits (Avatar) to 325 (Kling 3.0 Pro/4K). See the full Kling pricing guide; new accounts get 100 free credits to start.
