The best AI video generation API in 2026: how to choose
There is no single best video model, only the best fit for a job. It depends on clip length, resolution, sound, the inputs you have and the price you can carry at volume. This guide compares the current models on those terms, with prices from the Revana catalogue.
Why there is no single winner
Video models now ship every few months, and each release moves the line on something different: longer clips, better speech, sharper 4K, more reference images, lower prices. Public leaderboards are useful for a first look, but they rank models on general prompts, which says little about how a model handles your product, your characters or your style.
We do not publish benchmark scores or quality rankings. What we can give you is the facts that decide whether a model can do the job at all, taken from the catalogue, and a cheap way to test the ones that can.
The main video models compared
Prices are per second of output from the Revana catalogue in October 2026. "From" is the lowest listed rate, usually at the lowest resolution and without sound.
| Model | Maker | Longest clip | Resolution | Sound | From / s | Routes |
|---|---|---|---|---|---|---|
| Seedance 2.5 | ByteDance | 30 s | 480p, 720p and 1080p | yes | $0.11 | five routes |
| Seedance 2.0 | ByteDance | 15 s | 480p, 720p, 1080p and 4K | yes | $0.08 | three routes |
| Seedance 2.0 Mini | ByteDance | 15 s | 480p and 720p | yes | $0.03 | four routes |
| Veo 3.1 | 8 s | 720p, 1080p and 4K | yes | $0.20 | one route | |
| Veo 3.1 Fast | 8 s | 720p, 1080p and 4K | yes | $0.08 | two routes | |
| Veo 3.1 Lite | 8 s | 720p, 1080p and 4K | yes | $0.05 | one route | |
| Kling 3.0 | Kuaishou | 15 s | 720p, 1080p and 4K | yes | $0.09 | two routes |
| Kling 2.6 Pro | Kuaishou | 10 s | 1080p | yes | $0.07 | two routes |
| Wan 3.0 | Alibaba | 30 s | 480p, 720p and 1080p | yes | $0.05 | three routes |
| Hailuo 2.3 | MiniMax | 10 s | 768p and 1080p | no | $0.06 | two routes |
| Grok Imagine Video 1.5 | xAI | 15 s | 480p, 720p and 1080p | yes | $0.04 | one route |
Every model in the table takes the same request on Revana: a model id and an input object with the prompt, resolution, duration and so on. Each one has its own page on the models page with every option and price.
Which model fits which job
Long single clips
Seedance 2.5 and Wan 3.0 go up to 30 seconds in one generation. That suits continuous takes and full ad spots that would show a seam if stitched from shorter clips. Wan 3.0 also goes down to 2 seconds, which makes quick motion tests cheap. Our guides to Seedance 2.5 and Wan 3.0 cover both in detail.
Dialogue and sound
Seedance 2.5, Seedance 2.0, Seedance 2.0 Mini, Veo 3.1, Veo 3.1 Fast, Veo 3.1 Lite, Kling 3.0, Kling 2.6 Pro, Wan 3.0 and Grok Imagine Video 1.5 list sound generated with the picture. Pricing differs: Veo 3.1, Veo 3.1 Fast, Kling 3.0 and Kling 2.6 Pro list separate prices for clips with and without sound, while Seedance 2.5, Seedance 2.0, Seedance 2.0 Mini, Veo 3.1 Lite, Wan 3.0 and Grok Imagine Video 1.5 list one rate with sound on or off. If you will replace the soundtrack in editing anyway, a model with a separate silent rate can save money. See the Veo 3.1 pricing guide and the Kling 3.0 guide for prompting speech.
4K output
Seedance 2.0, Veo 3.1, Veo 3.1 Fast, Veo 3.1 Lite and Kling 3.0 list 4K. The per-second rate rises with resolution: Seedance 2.0, for example, lists $0.15 per second at 720p and $0.83 at 4K. Drafting at 720p and rendering only the final take at 4K keeps that under control.
Keeping characters and products consistent
Reference images let you pin a person, a product or a look across shots. Seedance 2.5 takes up to 30, Wan 3.0 takes up to 10, Seedance 2.0 takes up to 9, Seedance 2.0 Mini takes up to 9, Veo 3.1 Fast takes up to 3 and Veo 3.1 Lite takes up to 3. Start and end frames are another way to control a shot; the guide to input modes explains when to use which.
Vertical video
Seedance 2.5, Seedance 2.0, Seedance 2.0 Mini, Veo 3.1, Veo 3.1 Fast, Veo 3.1 Lite, Wan 3.0 and Grok Imagine Video 1.5 list 9:16 for stories, reels and shorts. Kling 3.0, Kling 2.6 Pro and Hailuo 2.3 list no aspect ratio option in the catalogue, so check the model page before relying on vertical output.
Drafts and high volume
Lower-cost options in the catalogue include Seedance 2.0 Mini (from $0.03 per second), Veo 3.1 Lite (from $0.05 per second), Grok Imagine Video 1.5 (from $0.04 per second) and Wan 3.0 (from $0.05 per second). They are good for testing prompts, previews and products that generate a lot of short clips. Results differ from the flagship models, so test the final quality on the model you will ship with.
What a minute of video costs
Most products need more than one clip. This table prices 60 seconds of finished video at 720p, made from as many clips as each model needs, with and without sound.
| Model | Silent | With sound |
|---|---|---|
| Seedance 2.5 | $12.00 | $12.00 |
| Seedance 2.0 | $9.00 | $9.00 |
| Seedance 2.0 Mini | $3.00 | $3.00 |
| Veo 3.1 | $12.00 | $24.00 |
| Veo 3.1 Fast | $4.80 | $6.00 |
| Veo 3.1 Lite | $3.00 | $3.00 |
| Kling 3.0 | $5.40 | $7.80 |
| Wan 3.0 | $5.40 | $5.40 |
| Hailuo 2.3 (768p) | $3.60 | no sound listed |
| Grok Imagine Video 1.5 | $4.20 | $4.20 |
You pay only for jobs that succeed, so failed attempts do not add to these numbers. The pricing page has every rate.
How to evaluate models for your product
- Collect real prompts. Write 10 to 20 prompts from your actual use case, including the awkward ones: hands, text, fast motion, your own characters.
- Shortlist on facts. Drop any model that cannot meet your hard requirements for length, resolution, sound, aspect ratio or inputs.
- Draft cheaply. Run the prompts at the lowest resolution first. Fifteen 5 second drafts on Seedance 2.0 Mini at 480p cost $2.25 in total.
- Compare blind. Have someone who did not write the prompts pick the best clip for each, without knowing which model made it.
- Price the winner at your volume. Multiply the per-second rate by the seconds you expect to generate in a month, including retries and variations.
- Keep a second model ready. The router retries other routes for the same model, but it never swaps in a different model. If one model goes down, falling back to another is a decision for your code.
Why test through one API
Comparing models usually means opening accounts with several companies, learning several request formats and topping up several balances. On Revana every model takes the same request and draws on the same prepaid balance, so a comparison is a loop over model ids. The one API guide shows the code.
Routes are the upstream capacity behind each model. A model with more than one route can fall back automatically when one fails; a model with one route cannot. The comparison table above shows the count for each.
