- Only Gemini Omni Flash 1.1 is validated for Polish speech (8-second clips).

There is no single best AI video model. The 17 models in Fattly differ in price by a factor of 12, in clip length (up to 30 seconds), and in what they accept as input. Below is the whole catalog in one table, taken from the code that prices every generation, followed by a short guide to which model suits which job.

“Credits per 5 s” is the unit we use for pricing. A 10-second clip costs twice as much as a 5-second one, and the longest clip (30 seconds in Seedance 2.5) costs 1800 credits. Formats are the aspect ratios you can pick: 16:9 for YouTube and banners, 9:16 for Reels, TikTok and Shorts, 1:1 for the feed.
Which model for which job
- Quick tests and drafts: MiniMax H3 Turbo, PixVerse v6 and MiniMax Hailuo are the cheapest. Check your idea here before you pay for a flagship.
- Cinematic motion and camera work: Kling 3.0 Pro and Seedance 2.0 are described in our catalog as the ones built for it. Kling 3.0 Standard and Seedance 2.0 Fast are the cheaper versions of the same families.
- Long clips and many references: Seedance 2.5 goes up to 30 seconds and takes up to 50 reference images, which helps when the same product or person has to look the same in every shot.
- Sound together with the picture: Gemini Omni Flash 1.1, Seedance 2.5 and Kling 3.0 Pro generate audio with the video; PixVerse v6 has it as an option. Kling speaks English or Chinese.
- Polish speech: Gemini Omni Flash 1.1 is the only model we have validated for it (tested in the Ad Studio in October 2026).
- Stylized and anime looks: PixVerse v6.
- Text only, no photo as a starting frame: Wan 2.7.
Text to video or photo to video?
16 of the 17 models can start from your own photo, which is the safest way to keep a product looking like your product. Without a photo the model invents the whole scene from the prompt. To animate a picture you already have, see the photo animation tool; for a broader market view, read our AI video generator ranking.
How to choose in practice
- Write the prompt once and run it as a 5-second clip in the cheapest model.
- If the motion looks wrong, run the same prompt in Kling 3.0 Standard or Seedance 2.0 Fast, then in the flagship.
- Compare the clips side by side. Keep the cheaper model if the difference does not matter for your use.
- Render the final length only once you have picked the model, because cost grows with every second.
Frequently asked questions
Which AI video model is the best?
It depends on the job. For cheap tests use the cheapest models, for cinematic motion Kling 3.0 Pro or Seedance 2.0, for long clips with many references Seedance 2.5. The table above shows the price of each, so you can compare before you generate.
How much does an AI video cost in Fattly?
It depends on the model and the length. Five seconds costs from 25 credits to 300, and the cost grows in proportion to the clip length. The cheapest possible clip is 25 credits.
Can I make a video with sound?
Yes. Gemini Omni Flash 1.1, Seedance 2.5 and Kling 3.0 Pro generate audio together with the picture, and PixVerse v6 has optional audio. For any other model you can add a voice afterwards with the AI voiceover tool.
