Which AI video model to choose: Seedance, Kling, Veo and others by task

Alen founder of KADR Updated 2026-10-14 5 min read

There is no single best video model for everything: each one is strong at something different. In short: Seedance for narrative scenes and a stable character, Kling for people and camera movement, Veo for detail, lighting, physics and sound, Hailuo and Wan for inexpensive clips. The price of 6 seconds at 1080p on KADR varies about tenfold: from 84 rubles on Veo 3.1 Lite to 849 rubles on Seedance 2.5 (October 2026). Below is a «task and model» table, a price comparison and a simple rule for not overpaying.

The short answer

Choosing a video model comes down to two questions: what should be in frame and how much you are willing to pay per attempt. Quality among the top models is close, but their character differs: one holds a face better, another lighting, a third physics.

Table: task and model

Task Main choice Cheaper alternative
A narrative clip longer than 15 seconds in one piece Seedance 2.5 Seedance 2.0 plus editing
Realistic people, facial expressions Kling v3 at 1080p Kling v3 at 720p
Complex camera movement Kling v3, Kling O1 Veo 3.1 Fast
Detail, lighting, texture Veo 3.1 Veo 3.1 Fast
Talking character, lip sync Veo 3.1, Kling v3 Veo 3.1 Fast
Animation, one character across many scenes Seedance 2.0 Seedance 1.5 Pro
Complex physics (water, fabric, collisions) Veo 3.1 Veo 3.1 Fast
Reels and bulk content Veo 3.1 Lite, Seedance 1.5 Pro Grok Imagine
Animating a photo Kling v3, Hailuo 2.3 Wan 2.6
Drafts and prompt tuning Seedance 1.5 Pro at 480p Veo 3.1 Lite

The character of each model

Seedance (ByteDance). Story, composition, a stable character from a reference. Version 2.5 makes up to 30 seconds at a time and accepts up to 50 references. Downside: strict moderation of real faces. More: Seedance 2.0, Seedance 2.5.

Kling v3 (Kuaishou). People, facial expressions, camera movement. More relaxed about photos of real people, so it is often used for animating photos and avatars. Kling v3 review.

Veo 3.1 (Google). Detail, lighting, native sound. The full version works only at 1080p. There is a quicker Fast and a cheaper Lite. Veo 3.1 review.

Sora 2 Pro (OpenAI) is no longer available: OpenAI shut Sora down and switched off the API on 24 September 2026. For physics and photorealism with sound take Veo 3.1, for long story clips Seedance 2.5, for people and camera Kling v3.

Hailuo 2.3 and Wan (MiniMax and Alibaba). Inexpensive workhorse models for short scenes and photo animation. Hailuo and Wan review.

Grok Imagine Video (xAI). A fast, cheap 720p model for simple clips. Grok Imagine review.

Price comparison

KADR prices, 6 seconds, 1080p, sound on, October 2026:

Model Tokens Rubles
Veo 3.1 Lite 53 ~84
Hailuo 2.3 55 ~87
Wan 2.6 66 ~104
Veo 3.1 Fast 80 ~126
Seedance 1.5 Pro 86 ~136
Kling v3 106 ~168
Wan 2.7 125 ~198
Veo 3.1 264 ~417
Seedance 2.0 362 ~572
Seedance 2.5 537 ~849

This is not a public offer. Models without 1080p are not in the table: Grok Imagine Video (720p, 49 tokens), Kling Video O1 (720p, 5 s for 62 tokens; O1 only does 5 or 10 s) and Seedance 2.0 Fast (720p, 109).

The gap between the first and last row is tenfold. So the choice of model affects the budget more than any discount. The price of a minute for every model is worked out in the article on how much a minute of AI video costs.

Three rules for not overpaying

1. Cheap drafts, expensive final. Tune the prompt on a cheap model at low resolution. Seedance 1.5 Pro at 480p costs 19 tokens for 6 seconds. Once the scene works, move the prompt to the flagship.

2. Switch sound off if you do not need it. On most models sound nearly doubles the price. Veo 3.1 costs 132 tokens without sound and 264 with it. If music goes on top anyway, you do not need sound from the model. The exception is Seedance 2.5: there sound is already included in the price.

3. Do not take the flagship out of habit. For a reel with a simple action, Veo 3.1 Lite gives a result that is indistinguishable from the flagship on a phone screen. The flagship is needed where the difference shows: close-ups of faces, complex physics, ads on a big screen.

If the model refuses

A refusal is almost always about moderation: a real face, a well-known character, someone else’s brand. Developers have different policies, and what Seedance blocked may go straight through in Kling. Switch models before rewriting the prompt.

If you used to work in Sora: Sora was shut down, what to use instead.

If you are just starting: how to make a video with AI from scratch. If a model refused: why AI refuses to generate.

In short

Seedance for story and character, Kling for people and camera, Veo for detail, physics and sound, Hailuo, Wan and Grok for inexpensive clips. Prices differ tenfold between models, so do drafts on cheap ones and keep flagships for the final take.

Frequently asked questions

What is the best AI video model in 2026?
There is no single best one. Seedance 2.0 and 2.5 are stronger at narrative scenes and holding a character, Kling v3 at people and camera movement, Veo 3.1 at detail, physics and sound. Choose by task and budget.
Which model is best for video with people?
For realistic people Kling v3 is the usual pick: it holds faces and expressions well and is more relaxed about photos of people. Seedance filters real faces more strictly and may refuse the request.
Which AI video model is the cheapest?
On KADR the lowest price is Seedance 1.5 Pro at 480p: 19 tokens for 6 seconds, about 30 rubles. At 1080p the most affordable is Veo 3.1 Lite: 53 tokens for 6 seconds with sound, about 84 rubles (October 2026).
Which model makes the longest video?
Seedance 2.5 generates up to 30 seconds in a single pass. Seedance 2.0 and Kling v3 go up to 15 seconds, Veo 3.1 up to 8. Longer videos from short-segment models are assembled in an editor.
Which model is best for an animated film?
For an animation with one character across many scenes Seedance is the usual choice: it holds the style and the character from a reference well. For short animations Kling and Hailuo work too.
Do I need sound from the model?
Only if someone speaks in frame or in-frame sound effects matter. On most models sound nearly doubles the price, and music and voice-over are easier to add in editing. On Seedance 2.5 sound does not change the price.
