Top AI Video Models 2026: Pricing & API Compared
Compare top 2026 AI video models, Sora 2, Kling V3, MiniMax Hailuo 2.3, and Vidu Q3 Pro, on price per second, clip length, resolution, audio, and API access.
If I were buying an AI video model today, I’d sort it like this: use MiniMax Hailuo 2.3 for the lowest cost, Kling V3 / V3 Omni for polished visual work, Vidu Q3 Pro for built-in audio and longer scene work, and Sora 2 Preview only for short-term tests because its API is set to retire on September 24, 2026.
Here’s the short version:
- Lowest price: MiniMax Hailuo 2.3 at $0.025/sec
- Middle ground for polished clips: Kling V3 / V3 Omni at $0.0672/sec on APIMart
- Built-in audio + longer clips: Vidu Q3 Pro at $0.12/sec
- Best realism, but short runway: Sora 2 Preview at $0.08/sec on APIMart
- One API for all four: APIMart, with one integration and a single
model_idswitch
The numbers matter fast. A 15-second clip can run from about $0.38 to $1.80 at APIMart rates. And once I factor in re-runs, audio work, and post-production, list price stops being the whole story.
This comparison looks at the points that matter most:
- Price per second
- Clip length
- Resolution
- Text-to-video and image-to-video support
- Audio support
- Render time
- Commercial use terms
- API setup and limits

I tested every major AI video model so you don't have to
Quick Comparison
| Model | APIMart Price | Max Clip Length | Max Resolution | Audio | Best Fit |
|---|---|---|---|---|---|
| APIMart | Varies by model | Varies | Varies | Varies | One API across many models |
| Sora 2 Preview | $0.08/sec | 25 sec | Up to 1080p | Yes | High-realism clips before sunset |
| Kling V3 / V3 Omni | $0.0672/sec | 10 sec / 15 sec | Up to 4K | Yes | Product demos, multi-shot scenes |
| MiniMax Hailuo 2.3 | $0.025/sec | 10 sec | Up to 1080p | No | Low-cost drafts and motion-heavy clips |
| Vidu Q3 Pro | $0.12/sec | 16 sec | 1080p | Yes | Narrated demos and multi-shot ads |
My takeaway: if you want to keep costs down, draft with Hailuo. If you need polished shots, move to Kling. If synced sound matters, look at Vidu. If you want Sora, use it only with the September 24, 2026 cutoff in mind.
That’s the core decision in one view. The rest is matching price, output, and API limits to the kind of videos you plan to make every month.
1. APIMart

APIMart gives you one API gateway for AI video generation. That means you can compare models through the same setup instead of stitching together separate tools and docs for each one.
Pricing
Pricing is based on usage. MiniMax Hailuo 2.3 starts at $0.025/sec. Kling V3 and Kling V3 Omni cost $0.0672/sec at 720p. Sora 2 Preview is $0.08/sec, and Vidu Q3 Pro is $0.12/sec.
In practice, fast variants make sense for prototyping and high-volume social content. Standard models are a better fit for final production, where output quality matters more than raw speed.
API Access
All endpoints use Bearer Token authentication through the Authorization header [2][3]. Video generation is asynchronous, so a POST request to /v1/videos/generations returns a task_id, and you then poll Get Task Status to get the result [2][4].
The setup is OpenAI-compatible, which is a big help if your team already uses OpenAI's SDK. You don't need to rebuild your whole workflow just to test a new video model.
For avatar or brand assets, APIMart supports Asset URLs like asset://asset_a, so teams can reuse the same files without uploading them again [3]. That's especially useful when you want to switch models while keeping the rest of the process the same.
Output Capabilities
APIMart supports both text-to-video and image-to-video inputs. Common aspect ratios include 16:9, 9:16, and 1:1, plus widescreen options for more cinematic work.
Audio is optional in workflows that support it. Camera control is also available through bracketed commands, which gives teams more precise cinematic movement control [5].
Commercial Terms
Commercial use is supported for production workflows.
2. Sora 2 Preview

Sora 2 Preview is OpenAI's high-realism video model. Its big draw is photorealism and motion that looks natural on screen. The standalone consumer app was retired in April 2026, and the API is set to retire on September 24, 2026 [8]. So for production teams, this is mainly a short-window option for projects that can go live before that cutoff.
Pricing
For buyers, the main trade-off is simple: better realism, higher cost, and limited API runway. APIMart lists it at $0.08/sec.
Direct API pricing is billed by the second. Standard runs at $0.10/sec for 720p output, while Pro ranges from $0.30 to $0.50/sec for higher-resolution video [6][7]. And there’s a practical catch here: teams usually regenerate clips a few times before they ship anything. Because of that, planning around 3x the listed generation cost is a safer budget baseline [8].
| Tier | Resolution | Cost per Second | Clip Lengths |
|---|---|---|---|
| Standard | 720p | $0.10/sec [6] | 4, 8, 12 seconds [8] |
| Pro | Up to 1080p | $0.30–$0.50/sec [7] | 10, 15, 25 seconds [8] |
API Access
The API follows an async workflow. You submit a job, then pull the result back through polling or webhooks. Rate limits start at 25 requests per minute on Tier 1 and go up to 375 RPM on Tier 5 [10].
Generation is not instant, either. A 10-second clip takes about 90 seconds to render [1][10]. That delay matters most when a team wants fast back-and-forth testing and edits.
Output Capabilities
Sora 2 supports both text-to-video and image-to-video input modes. It also produces synchronized audio in the same pass, including dialogue, sound effects, and ambient noise [9][10]. That means you’re not just getting silent footage and patching the rest together later.
On the output side, clips include C2PA Content Credentials [8][11]. Maximum length goes up to 25 seconds on the Pro tier [8][9].
Commercial Terms
Commercial use is allowed on paid plans [11]. Users own the generated output, but the rule set is tight. You can’t use real people’s likenesses, public figures, or copyrighted characters without explicit authorization, and political advertising is banned [11][12].
There’s also a legal gap buyers should pay attention to. IP indemnification mainly covers API and Enterprise customers, which means Plus and Pro users do not get the same protection for third-party infringement claims [11][13]. For a production team, that can matter just as much as video quality.
3. Kling V3 / Kling V3 Omni

Kling V3 and Kling V3 Omni launched in February 2026 on an MVL system that takes text, images, audio, and video. The split between the two is pretty simple: V3 handles single-shot clips, while Omni is built for multi-shot sequences with the same character staying consistent from shot to shot. As of May 2026, Kling V3 Omni has the #1 ELO benchmark score of 1,243 among AI video models [17]. That lines up with what it’s built to do well: camera control and steady multi-shot output. It also explains why the two versions differ in price, queue time, and clip length.
Pricing
Pricing depends on where you buy access.
On APIMart, both versions cost $0.0672/sec at 720p. Through the official Kuaishou API, Standard costs $0.084/sec without video input or $0.126/sec with video input. Pro costs $0.112/sec without video input and $0.168/sec with video input [15]. On top of that, Omni generations use about 1.6x more credits than a standard V3 generation of the same length [14].
There’s also a plan limit to watch for. Omni mode is only offered on the Pro plan at $29.99/month and the Ultra plan at $59.99/month [14][15].
API Access
Queue times can get long on the Free tier. During peak hours, users may wait 30–47 minutes for a job to start [15]. Pro and Ultra users get priority processing instead.
Omni is also a bit slower when you push quality up. At 4K, Omni rendering runs about 15% slower than Classic V3 because it has to process extra references [18]. So if you need to test prompts fast, standard V3 is the easier fit. If you’re planning a more polished sequence and can wait a bit, Omni makes more sense.
Output Capabilities
V3 supports native 4K at 60fps and produces clips up to 10 seconds long [15]. Omni stretches that to 15-second multi-shot sequences with up to 6 camera cuts in one generation. It also supports 12 named camera moves, including dolly, truck, pan, tilt, and crane [14][18][19].
That extra structure shows up in consistency too. Omni reaches 93% character consistency across a 28-clip multi-shot test [14]. And with Omni Elements, you can save up to 50 reusable named characters and props per account [14]. That’s handy if you’re building repeatable ad sets, product scenes, or a cast that keeps showing up across videos.
Text output is another strong point. It stays readable in about 80% of generations [15], which helps when you need logos, signs, or price tags to remain clear in e-commerce or marketing work.
Both versions come with built-in audio in:
- Chinese
- English
- Japanese
- Korean
- Spanish
Omni also adds a single audio timeline, so dialogue and ambient sound carry across cuts in a smoother way [15][14][18].
Commercial Terms
The Free tier does not allow commercial use [15]. The Ultra plan includes a full commercial license [14][15]. Free outputs also come with watermarks and are capped at 720p, while paid tiers remove the watermark and open up 1080p through 4K output [15].
There are also data and policy limits to keep in mind. Prompts and generated videos are stored in China and fall under Chinese data rules [16]. Kling also applies content filtering, including limits on politically sensitive topics, and it has unexpectedly blocked some medical visualizations [15][16].
4. MiniMax Hailuo 2.3

MiniMax Hailuo 2.3 is the low-cost motion specialist in this lineup. If your main goal is dynamic movement without spending much, this is the one to look at. It does especially well with human motion, small facial reactions, and stylized looks like anime, ink wash, and game CG. The tradeoff is pretty clear: you give up some photorealism and built-in audio, but you get lower costs and tighter motion control.
Pricing
On APIMart, Hailuo 2.3 costs $0.025 per second. With direct API usage, a 6-second clip usually lands around $0.27–$0.32 [20][24]. Hailuo 2.3 Fast starts at about $0.19 per video and can lower batch costs by up to 50% [22][25].
That makes it a strong pick when budget comes first, especially for short clips with lots of action.
API Access
minimax/hailuo-2.3 supports both text-to-video and image-to-video. minimax/hailuo-2.3-fast is image-to-video only [26][27].
Watch the resolution and duration limits before you send a job. 1080p clips are capped at 6 seconds, and if you want 10 seconds, you need to drop to 768p [24][26].
Output Capabilities
Hailuo 2.3 outputs native 1080p video at up to 30fps [21][23]. It fits best for short-form ads, stylized explainers, anime promos, and motion-heavy product clips.
One limitation matters in practice: text-to-video is restricted to landscape-only 1366×768. So for production work, image-to-video is usually the better route [20][24].
It also supports bracketed motion commands such as:
[Push in][Pan left][Tilt up]
Those commands give you tighter camera direction, which is handy when you want the shot to move in a very specific way [20][21].
Render times are decent for the price. Standard clips take about 90 seconds, while 1080p renders can take 3 to 5 minutes [20][21]. There’s no native audio in the output, so teams that need synced sound should plan to handle that in post-production.
Commercial Terms
Paid plans include commercial use, while the free trial does not. Paid plans also remove watermarks [25][26]. For any client or brand work, use a paid tier.
5. Vidu Q3 Pro

Vidu Q3 Pro ranked #2 on the Artificial Analysis Video Arena leaderboard as of early 2026 [29]. That standing puts it near the top of the pack, and the feature set backs it up. It supports clips up to 16 seconds, which gives you enough room to tell a short story in a single pass. That makes it a strong fit for narrated product demos, short explainers, and multi-shot social ads.
What pushes Vidu Q3 Pro further up the stack is its mix of longer outputs, built-in audio, and tighter control over multi-shot scenes.
Pricing
On APIMart, Vidu Q3 Pro costs $0.12 per second at 1080p [28]. Vidu also lists $0.12/sec at 1080p standard, $0.06/sec off-peak, $0.10/sec at 720p, and as low as $0.045/sec at 540p [28][31].
API Access
The API uses a simple REST flow: send a POST request to create a task, then poll with GET or use callback_url [33][34]. Authentication is straightforward with the Authorization: Token {key} header.
Supported workflows include:
- Text-to-video with prompts up to 5,000 characters
- Image-to-video
- Start/end-frame-to-video interpolation
Vidu Q3 Pro supports 540p, 720p, and 1080p at 24fps, with aspect ratios that cover 16:9, 9:16, 1:1, 3:4, and 4:3 [30][33]. Those controls make a big difference when you need sound, scene changes, and steady framing in one pass.
Output Capabilities
Two features stand out here: native audio and Smart Cuts. Native audio generates synchronized speech, sound effects, and background music in the same pass [29][32]. That can save a lot of cleanup later.
Smart Cuts detects scene boundaries on its own for multi-shot storytelling, which helps keep product demos and explainers organized without as much editing work [29][32]. Vidu Q3 Pro also scored 7.5/10 for physics accuracy, which points to smoother motion [29]. Typical generation time is about 25 seconds [1].
Commercial Terms
Paid plans include commercial use for ads, client work, and internal materials [35]. Paid tiers also allow white-label use, and the Cloudflare deployment offers zero data retention [30][35].
Pros and Cons by Budget and Production Goal
No model is the right pick for every job. That’s why the table below turns raw specs into a simpler buying call based on budget and what you’re trying to make.
| Model | Decision Signal | Ideal Use Case | Budget Fit (USD) |
|---|---|---|---|
| APIMart | Unified access to multiple models | Teams that want flexible access across multiple workflows | Varies by model |
| Sora 2 Preview | Short-term testing only | Short-term evaluation before September 24, 2026 sunset | $0.08/sec |
| Kling V3 / Kling V3 Omni | Best for cinematic product demos and polished visuals | Product demos, hero shots | $0.0672/sec at 720p |
| MiniMax Hailuo 2.3 | Lowest-cost, fastest draft option | Rapid iteration and high-volume short clips | $0.025/sec |
| Vidu Q3 Pro | Best for complex scenes and premium clips | Complex scenes, narrated demos | $0.12/sec at 1080p |
A simple way to handle this: draft at the low end, then spend more only on the shots that will make the final cut.
Price is only half the story. The other half comes down to what the clip needs - clean polish, tighter motion control, or built-in audio.
For teams watching spend, a mixed setup usually makes more sense than running everything through one high-end model. Multi-model routing can cut costs by 30% to 50% versus a single premium model [1].
For product demo videos, native audio can trim post-production costs by $0.50 to $2.00 per video [1].
For course content, these models work best for b-roll, explainers, and product visuals. They’re less suited for talking-head lessons.
For entertainment prototypes, Kling V3 / Kling V3 Omni is a strong fit for hero shots, but it can slow down iteration.
Conclusion
Use a unified API when you're testing options. Switch to direct integration when one model becomes your main production pick.
MiniMax Hailuo 2.3 at $0.025/sec works well for high-volume drafts and short social clips. Kling V3 / Kling V3 Omni at $0.0672/sec sits in the middle for polished product visuals. Vidu Q3 Pro at $0.12/sec is better suited for complex scenes and premium deliverables.
The key is simple: judge cost by usable output, not list price alone. A lower rate doesn't help much if you need extra passes, fixes, or edits. So budget matters, but it's only one piece of the call.
Commercial rights matter on every paid tier. Native audio matters when dialogue or sound effects are part of the final cut. Higher resolution matters only when the job calls for it. Match the model to the work: draft at a low cost, polish with care, and spend more only when audio, continuity, or resolution changes the final result.
FAQs
Which model is best for drafts vs. final videos?
For fast drafts, use models like Wan 2.6. They’re built for quick, low-cost iteration during brainstorming and prototyping.
For final, higher-quality videos, go with premium models like Kling 3.0 or Kling Video O3. Turbo variants also help when you want faster output and can accept a small drop in quality before paying for a premium final render.
How much should I budget for re-runs and edits?
Plan for total costs to land around 1.5x to 2x the base per-second price. Why? Iteration eats into the budget fast, and teams often throw out 30% to 50% of early generations.
Failed generations are normal. That’s why it often makes sense to prototype with a lower-cost model like Kling 2.5 Turbo ($0.042/sec) before spending more on pricier runs. This can cut waste in a big way.
It’s also worth watching for extra fees. Native audio and higher resolutions can come with major surcharges, and the price for the same model can swing a lot depending on the platform.
When should I use a unified API instead of direct integration?
Use a unified API when you want to add AI video generation to your app without dealing with infrastructure yourself. You get one developer interface that connects to multiple models and services through a single integration.
This works well if you want a simpler setup and the freedom to switch between models or use different features - like resolution, generation speed, or audio support - without building separate pipelines for each one.
