Quick answer
In WorldofAI’s test of eight AI video models, Kling 4.0 came first with 35 out of 40, two points ahead of Seedance 2.5 on 33. Every model got the same prompt (an astronaut walking through a rainy neon city) and the same settings: 10 seconds at 16:9, one attempt each. Kling won on camera movement and following the action. Seedance 2.5 had the richest close-up detail but skipped two requested moments. Gemini Omni Flash 1.1 and MiniMax H3 tied with Seedance 2.5 on 33. Treat this as one creator’s scored test of a single shot, in a video sponsored by Higgsfield, not a final verdict.
Key takeaways
- Kling 4.0 won overall with 35/40, scoring 9 for motion, consistency and realism.
- Seedance 2.5 scored 33/40. It looked the most polished but missed the car splash and the head turn.
- Three-way tie for second: Seedance 2.5, Gemini Omni Flash 1.1 and MiniMax H3 all scored 33.
- Best at following the brief: Gemini Omni Flash 1.1 and MiniMax H3, both 9/10 for prompt accuracy.
- Seedance 2.5 beat Seedance 2.0 by 3 points (33 against 30) and, according to the video, doubles the maximum clip length from 15 to 30 seconds.
- The scores are one person’s judgement on one prompt and one attempt per model. Your results will vary with your subject and style.
- Practical lesson: run your own small test with your own prompt before you commit money to any one tool.

AI video models now arrive so quickly that it is hard to know which one is worth your time or your credits. This week WorldofAI tried to cut through the noise with a simple, fair-looking experiment.
This article breaks down that Kling 4.0 vs Seedance 2.5 showdown, plus the six other models in the line-up. We cover the scores, what each model did well and badly, what the test can and cannot tell you, and how to run a similar test for your own videos.
Watch: the source video
What this video covers: WorldofAI gives eight AI video models (Kling 4.0, Seedance 2.5, Seedance 2.0, MiniMax H3, Wan 3.0 Prime, Grok Imagine 1.5, FLUX.3 Video and Gemini Omni Flash 1.1) the same 10-second astronaut-in-the-rain prompt on Higgsfield, scores each one out of 40 and names Kling 4.0 the winner.

Kling 4.0 vs Seedance 2.5: which AI video model won?
Kling 4.0 won. It scored 35 out of 40, against 33 for Seedance 2.5.
The difference came down to what each model did with the brief. Kling produced what the creator called the smoothest camera of the eight, and the astronaut actually turned their head towards a skyscraper, as the prompt asked.
Seedance 2.5 produced richer suit detail and lighting, and the camera moved in closer. But it left out the passing car splash and the head turn. That cost it on prompt accuracy (7/10 against Kling’s 8/10) and on motion (8/10 against 9/10).
| Category | Kling 4.0 | Seedance 2.5 |
|---|---|---|
| Prompt accuracy | 8 | 7 |
| Motion and physics | 9 | 8 |
| Consistency | 9 | 9 |
| Realism | 9 | 9 |
| Total (out of 40) | 35 | 33 |
💡 Tip: A two-point gap on one prompt is small. If you care most about polished close-ups rather than exact actions, Seedance 2.5 may still suit you better. The only way to know is to test both on your own shot.
How did WorldofAI run the test?
The creator ran every model inside Higgsfield, a platform that lets you pick from many AI video models in one place. He pasted the prompt once, set it to 10 seconds and 16:9, and only changed the model between runs.
The prompt asked for a single continuous tracking shot: an astronaut in a weathered white spacesuit walking slowly through a crowded futuristic city at night, in heavy rain. It included several specific moments to check:
- The camera moves backwards in front of the astronaut, keeping them centred.
- Pedestrians with transparent umbrellas walk around the astronaut.
- A passing vehicle splashes water across the road.
- The astronaut briefly turns their head towards a glowing skyscraper.
- Realistic rain and reflections, a 35mm lens look, no cuts, no text and no logos.
Each clip was scored out of 10 in four categories, for a maximum of 40:
| Category | What it checks |
|---|---|
| Prompt accuracy | Did the model follow the brief and include each requested moment? |
| Motion and physics | Walking, rain, the splash and the camera move |
| Consistency | Does the astronaut stay the same, with the same suit, from start to finish? |
| Realism | Does it look filmed, or obviously AI? |
Two models could not use the same output settings. According to the video, MiniMax H3 only offered 2K resolution and Grok Imagine 1.5 topped out at 720p, so each got its closest option. Every model produced its clip on the first attempt.
⚠️ Warning: This is a sponsored video, and every model ran on the sponsor’s platform. That does not make the scores wrong, but it is worth knowing. The creator also says plainly that the scores are his own call.
What were the scores for all 8 AI video models?
Here are the final scores as shown in the video, highest first:
| Model | Prompt / Motion / Consistency / Realism | Total |
|---|---|---|
| Kling 4.0 | 8 / 9 / 9 / 9 | 35 |
| Gemini Omni Flash 1.1 | 9 / 8 / 8 / 8 | 33 |
| MiniMax H3 | 9 / 8 / 8 / 8 | 33 |
| Seedance 2.5 | 7 / 8 / 9 / 9 | 33 |
| Wan 3.0 Prime | 8 / 8 / 8 / 8 | 32 |
| Seedance 2.0 | 8 / 7 / 8 / 7 | 30 |
| FLUX.3 Video | 7 / 7 / 8 / 7 | 29 |
| Grok Imagine 1.5 | 8 / 6 / 7 / 7 | 28 |
The category winners were:
- Best prompt accuracy: Gemini Omni Flash 1.1 and MiniMax H3 (9/10 each).
- Best motion and physics: Kling 4.0 (9/10).
- Most consistent: Kling 4.0 and Seedance 2.5 (9/10 each).
- Most realistic: Kling 4.0 and Seedance 2.5 (9/10 each).
Notice how close the field is. Only 7 points separate first from last, and five of the eight models scored 32 or more.

How did each model handle the shot?
Each model got a one-line verdict in the video. Here is our plain-English summary of what the creator saw:
Kling 4.0 (35/40)
The smoothest camera move of the group, and the head turn really happens. The strongest all-rounder in this test.
Gemini Omni Flash 1.1 (33/40)
The splash, the head turn and the umbrellas were all there. It ticked almost every box in the brief, which is why it shared the top prompt-accuracy score.
MiniMax H3 (33/40)
It also hit the splash and the head turn, with a darker, moodier look overall.
Seedance 2.5 (33/40)
Beautiful suit detail and lighting, with top marks for consistency and realism. But there was no splash and no head turn.
Wan 3.0 Prime (32/40)
The creator said it felt like real street footage. The catch: the astronaut’s visor was wide open, which breaks the spacesuit look.
Seedance 2.0 (30/40)
It got the umbrellas and the passing car right, but the crowd looked copy-pasted.
FLUX.3 Video (29/40)
The best crowd faces of the lot, but the astronaut got lost among the pedestrians, so the main subject was weaker.
Grok Imagine 1.5 (28/40)
The biggest splash, but it erupted like a geyser and the camera drifted. Motion and physics scored only 6/10, the lowest single score in the test.
Is Seedance 2.5 better than Seedance 2.0?
On this shot, yes, by 3 points (33 against 30). The two versions were good at different things, though.
- Seedance 2.5 moved in closer, with much richer suit detail and lighting.
- Seedance 2.0 included more umbrellas and the passing car, so it followed more of the brief.
- Clip length: according to the video, Seedance 2.0 tops out at 15 seconds per generation and Seedance 2.5 at 30 seconds.
If you already use Seedance 2.0 for scenes with lots of action, it may be worth comparing both before switching. Newer does not always mean better for every brief.
What does this test tell you, and what does it not?
It shows how a handful of current models handle one demanding, realistic shot. It does not tell you which model is best for your work.
That is not a criticism of the creator, who was open about his method. It is simply the limit of any single test.
🔎 Unconfirmed / rumour: We have not tested these models ourselves, and the model names, versions and resolution limits are as described in the video. The scores are the creator’s personal judgement from one attempt per model. Pricing, speed and credit costs were not compared, and results on other platforms or with other settings may differ.
Things the test does not cover:
- Other styles: animation, product shots, talking heads or text on screen may favour different models.
- Consistency across runs: one lucky or unlucky generation can swing a score.
- Cost per usable clip: a cheaper model that needs two tries may still cost less than a pricey one.
- Speed: waiting times were sped up in the video.
- Usage rights: licence terms differ between tools and plans.
Which AI video model should you use for your project?
Use the test results as a shortlist, then decide based on what your shot needs most:
| If your shot needs… | Models to try first (based on this test) |
|---|---|
| Smooth camera movement and believable motion | Kling 4.0 |
| Every action in your brief to happen | Gemini Omni Flash 1.1, MiniMax H3 |
| Polished close-ups and lighting | Seedance 2.5, Kling 4.0 |
| Longer single clips | Seedance 2.5 (up to 30 seconds, per the video) |
| Realistic crowds and faces | FLUX.3 Video |
💡 Tip: Keep a note of which model you used for each clip in a project. If you need to make a matching shot later, you will want the same model and settings.
How do you run your own AI video model test?
You do not need eight models. Three is plenty for most small businesses and creators. Here is a simple routine:
- Pick one real shot you actually need, such as a product scene or a background clip for an advert.
- Write one detailed prompt with three or four specific moments you can check, like the splash and head turn in this test.
- Fix the settings: the same length, aspect ratio and resolution for every model.
- Run each model once, then a second time, so one lucky clip does not decide it.
- Score each clip on prompt accuracy, motion, consistency and realism, and note the credits used.
- Pick the winner for that type of shot, not for everything.
Our guide on how to compare AI video generators fairly before you pay includes a ready-made scorecard and a way to work out the cost of each usable clip.
⚠️ Warning: Before you publish any AI video, check the tool’s licence for commercial use, avoid real people’s likenesses without consent, and label AI content where your platform asks you to.
Who is this comparison useful for?
This comparison suits you if:
- you make short adverts, social clips or b-roll and want a sensible shortlist of models to try,
- you already use one of these tools and want to know whether to test a rival,
- you are choosing a platform such as Higgsfield that offers several models in one place.
It matters less if:
- you mostly make talking-head or avatar videos, which these models were not tested on,
- you need animation, logos or on-screen text,
- you only make a few clips a year, where any of the top four would likely do the job.
