Best AI Video Model: Kling vs Hailuo vs Wan Compared
A practical comparison of the four AI video models on Zvidy — motion quality, speed, duration limits, aspect ratios, and cost per clip — with clear picks per use case.
"Which model should I pick?" is the question every new user asks. We run all four of these models daily; here is the honest, practical answer — no benchmark charts, just what each one is actually good at.
The lineup at a glance
| Model | Best for | Durations | Ratios | From | | ------------------- | ---------------------------------- | -------------- | ---------------------------- | ---------- | | Kling 2.6 | Cinematic motion, viral clips | 5s / 10s | 9:16, 16:9, 1:1 | 28 credits | | Kling 3.0 Turbo | Flexible length, image-to-video | 3–15s | 9:16, 16:9, 1:1 + 720p/1080p | 15 credits | | Hailuo 02 | Fast drafts, expressive characters | 6s / 10s | auto | 12 credits | | Wan 2.6 | Budget volume, stylized looks | 5s / 10s / 15s | auto + 720p/1080p | 12 credits |
Kling 2.6 — the default for a reason
If a clip needs to look expensive — believable physics, natural camera moves, film-like lighting — Kling 2.6 is the strongest option in the lineup. Every showcase video on our homepage was generated with it, unedited. Its weakness is rigidity: fixed 5s/10s durations and a higher price (28 credits per 5s). Use it when the clip is the product: ads, brand videos, anything going on a channel you're growing.
Kling 3.0 Turbo — the flexible one
The newest Kling generation trades a little of 2.6's polish for speed, a wider duration range (any length from 3 to 15 seconds), resolution control (720p or 1080p), and image-to-video support. The 3-second option at 15 credits is the cheapest way to test a concept in Kling quality. Use it when you need a specific length — say a 12-second product story — or when animating an image with tight control.
Hailuo 02 — the sprinter
Hailuo generates noticeably faster and costs half as much as Kling 2.6. Character expressiveness is its standout trait — faces, gestures, and emotional beats read well. It picks the aspect ratio automatically from your prompt, which cuts one decision but removes one control. Use it for drafting: run 3–4 Hailuo iterations to find the right prompt, then spend Kling credits on the final.
Wan 2.6 — the volume play
At 12 credits for 5 seconds (and the only model reaching 15 seconds under 35 credits), Wan is the budget king. It leans stylized — illustration, anime, and painterly looks land better than photorealism. Use it for daily-posting volume, stylized content, and any project where quantity beats polish.
Which AI video model should you use?
- Is this the final, public clip? → Kling 2.6.
- Do I need a non-standard length or 1080p toggle? → Kling 3.0 Turbo.
- Am I still exploring the idea? → Hailuo 02.
- Am I posting daily / making stylized content? → Wan 2.6.
Because every model shares one credit balance on Zvidy, the smart workflow is cross-model: draft cheap, finish premium. That combination is roughly 40% cheaper than running everything on a premium model — and it's the single biggest cost saving our heavy users discover.
