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.

You can compare the current catalog inside Zvidy's image to video AI generator, where every compatible model shares one interface and the cost appears before generation.

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?

  1. Is this the final, public clip? → Kling 2.6.
  2. Do I need a non-standard length or 1080p toggle? → Kling 3.0 Turbo.
  3. Am I still exploring the idea? → Hailuo 02.
  4. 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.

When subject fidelity matters, run the same source and motion brief through the AI video generator from image. For a low-cost first pass, the free image to video AI generator explains which limits apply to gift credits and premium queues.

Generate one short draft and one premium final from the same brief. That controlled comparison is more useful than judging models from unrelated showcase clips.
