Kling 4.0, MiniMax H3 and Google's Gemini Omni are the three newest AI video models that make picture and sound together. They all landed in the last month, and they all claim to be the best. So we gave them the same prompt, the same settings and the same five seconds, and compared what came back: the shot, the speed, the price and the specs.
Key takeaways
Fastest: Gemini Omni 1.2 Flash, 35 seconds for a 5-second clip.
Cheapest: MiniMax H3, 53 credits for 5 seconds at 768p, about half of Kling 4.0.
Longest clips: Kling 4.0, up to 30 seconds in one take.
Sharpest: MiniMax H3 at 2K; Kling 4.0 and Gemini Omni top out at 1080p on AITube.
All three make sound, so describe what you want to hear as well as see.
The test: one prompt, three models
Each model got the same prompt: “A red fox trots through fresh snow in a quiet pine forest at sunrise, soft golden light, gentle breeze, birdsong, cinematic tracking shot.” Every clip was 16:9 and 5 seconds long, at each model's standard quality (720p for Kling 4.0 and Gemini Omni, 768p for MiniMax H3), with AITube's prompt enhancement off so each model read the words exactly as written.
Model | Render time | Credits for 5 s | What it made |
|---|---|---|---|
Gemini Omni 1.2 Flash | 35 s | 70 | A bright, wide forest with sun through the trees; the fox trots across and glances at the camera |
MiniMax H3 | 1 min 51 s | 53 | One continuous side-on tracking shot, rim-lit fur, pine branches blurred in front |
Kling 4.0 | 2 min 51 s | 104 | A wide sunrise shot of the fox crossing the snow, then a cut to a close tracking shot |
All three came back with an ambient soundtrack; MiniMax H3's was the quietest of the three. Render times are how long the model itself took; a busy hour can add a queue on top.
Specs side by side
Kling 4.0 | MiniMax H3 | Gemini Omni 1.2 Flash | |
|---|---|---|---|
Maker | Kuaishou | MiniMax | |
Clip length | 3 to 30 s | 4 to 15 s | 3 to 15 s |
Resolution on AITube | 720p or 1080p | 768p or 2K | 720p or 1080p |
Shapes | 16:9, 9:16, 1:1, 21:9 | 16:9, 9:16, 1:1, 4:3, 3:4, 21:9 | 16:9, 9:16 |
Start from a picture | Start and end picture | First and last picture | Start picture, or up to 6 reference images |
Sound | Stereo | Stereo | Yes, with lip-synced dialogue |
Credits for 5 s on AITube | 104 (720p), 156 (1080p) | 53 (768p), 87 (2K) | 70 (720p), 103 (1080p) |
150 credits cost $3 in a pack, so a 5-second clip works out at about $1.06 on MiniMax H3, $1.40 on Gemini Omni and $2.08 on Kling 4.0, and less on a monthly plan. A clip that fails costs nothing.
Kling 4.0: the longest single takes
Kuaishou opened Kling 4.0 to everyone on October 15, 2026. Its headline is length: one clip can run 3 to 30 seconds with stereo sound, twice Kling 3.0's limit. In our test it was the slowest and the dearest, but it was also the only one that edited for us, cutting from a wide sunrise shot to a close tracking shot inside five seconds. Use a start and an end picture to keep a long take on track. More examples are on the Kling page.
MiniMax H3: the best price, up to 2K
MiniMax's H3, also called Hailuo H3, makes clips of 4 to 15 seconds with stereo sound, and is the only one of the three that renders at 2K. Through MiniMax's own API it costs $0.08 a second at 768p and $0.13 at 2K. It gave us the most “filmed” look of the three, a single smooth tracking shot with shallow depth of field, at about half Kling 4.0's price. It also takes the widest range of shapes, from 21:9 to 3:4. See more on the MiniMax page.
Gemini Omni 1.2 Flash: the fastest, built around references
Google released Gemini Omni 1.2 Flash on November 5, 2026. It makes 3 to 15-second clips with sound, including lip-synced dialogue, and it can follow up to six reference images, which helps keep a character or product the same from shot to shot. It was by far the fastest in our test. One limit to know: it turns down start pictures of real, recognisable people, so use Kling 4.0 or MiniMax H3 to animate a photo of someone. Google's other model, Veo 3.1, is still in AI Studio too; see the Google Veo page.
Which one should you use?
Testing ideas quickly: Gemini Omni, for its speed.
Making a lot of clips on a budget: MiniMax H3 at 768p, then 2K for the one you keep.
One long shot, up to 30 seconds: Kling 4.0.
The same character in every shot: Gemini Omni with reference images.
Animating a photo of a real person: Kling 4.0 or MiniMax H3.
Vertical Shorts: all three make 9:16.
Models read prompts differently, so the surest way to choose is to run your own prompt on two of them. AI Studio's compare mode does that side by side.
How to try them on AITube
Open AI Studio and go to Create.
Pick Kling 4.0, MiniMax H3 or Gemini Omni from the cards at the top; they're marked New.
Write your prompt, including the sounds you want, and choose the length, shape and quality.
Generate, then publish the clip to your channel or download it.
For faceless videos, AITube Faceless uses the same three models as per-scene tiers and adds the voiceover, captions and music. For prompt ideas, see Secret Prompts and How to Prompt; if you came from Sora, our Sora alternatives guide covers the rest of the field.
