Seedance 2.5 API: 7 Best Providers for Developers in 2026
Contents
Seedance 2.5 API access is now available from BytePlus and several third-party platforms. For developers, that is good news. Choosing a provider is harder.
The prices are not easy to compare. BytePlus and Fal use token-based billing. Other platforms show a price per second or use credits. Reference videos make things even less clear because each provider may charge for video input in a different way.
Concurrency is another issue. A cheap API is less useful if your app can only process a few video jobs at once. Real-person references also have different rules across providers.
We compared seven Seedance 2.5 API providers using the same basic criteria: 480p and 720p pricing without video input, concurrency, real-person reference support, free testing, and billing rules.
Seedance 2.5 API provider comparison
| Provider | 480p | 720p | Concurrency | Real-person reference | Free trial |
|---|---|---|---|---|---|
| BytePlus | $0.103/s | $0.231/s | 3-10 | Restricted | No |
| SeeGen AI | $0.12/s | $0.24/s | 480+ | Yes | Yes |
| Kie AI | ~$0.14/s | ~$0.315/s | 2-10 | Not confirmed | No |
| Atlas Cloud | From ~$0.134/s | ~$0.30/s | Not disclosed | Yes | No |
| PiAPI | $0.15/s | $0.35/s | 2-30 | Yes | Yes |
| WaveSpeed AI | $0.18/s | $0.36/s | 2 - 300 | Yes | Yes |
| Fal AI | ~$0.22/s | ~$0.47/s | 2-40 | Restricted | No |
BytePlus has the lowest base price in this comparison. SeeGen AI is only slightly more expensive at 720p, but it offers much higher concurrency and supports real-person references. PiAPI, and WaveSpeed also offer free testing, while Atlas Cloud and Fal AI can make more sense for developers who value a broader model catalog.

Seedance 2.5 API Pricing Without Video Input
| Provider | 10s at 720p |
|---|---|
| BytePlus | $2.31 |
| SeeGen AI | $2.40 |
| Atlas Cloud | ~$3.00 |
| Kie AI | ~$3.15 |
| PiAPI | $3.50 |
| WaveSpeed AI | $3.60 |
| Fal AI | ~$4.70 |
For text-to-video or image-to-video, the cost is easy to understand.
At 720p, a 10-second video costs about $2.31 on BytePlus and $2.40 on SeeGen AI. The same 10 seconds costs about $3.50 on PiAPI and $3.60 on WaveSpeed. Fal is around $4.70 based on its published per-second estimate.
PiAPI currently lists $0.15/s at 480p and $0.35/s at 720p. WaveSpeed lists $0.18/s and $0.36/s for the same resolutions when no reference video is used.
This makes BytePlus a strong choice when the main goal is simply getting the lowest base Seedance 2.5 generation cost.
But reference videos can change the picture.
How Video Input Changes the Price
Seedance 2.5 can use video references for motion, camera direction, editing, and other multimodal workflows. The problem is that providers do not all charge for this in the same way.
PiAPI uses a simple rule:
Output × Rate + Input Video × 50% of Rate
So a reference video is billed at half the selected output rate.
WaveSpeed uses another method. Without video input, 720p costs $0.36 per output second. With reference video, the rate drops to $0.22, but both the reference video duration and output duration are counted.
Fal does something similar with tokens. When video references are present, both input and output video duration are counted, but Fal applies a 0.6 multiplier to the token price. Image and audio references are not billed.
SeeGen AI also has separate rates for jobs with video input. Its current API documentation shows lower base rates for the combined input-plus-output calculation than for generation without video input.
The lesson is simple: if your app uses reference videos often, do not choose a provider by looking only at the advertised output price.
What Developers Should Check Beyond Price
Concurrency
Concurrency matters more once an app has real users.
A personal test project may work fine with two active jobs. A public AI video app may need dozens or hundreds.
WaveSpeed, for example, starts new accounts at two concurrent jobs. Its Silver tier can reach 300 after a paid top-up. Higher account tiers go beyond that, though they require much larger payments.
SeeGen AI publishes 480+ concurrency for its API packs. For developers building a Seedance-heavy product, that can matter more than saving one or two cents per second.
Real Human References Support
Real-person references also need a separate check. Here, “real-person support” means using a real person's photo or video as a reference. It does not mean generating a fictional person who looks realistic.
Free Test for Seedance 2.5
Free trials matter for the same reason. Testing a web demo is useful, but developers should check whether the free access also works for their API workflow. WaveSpeed, for example, gives new accounts $1 in trial credit for seedance 2.5. SeeGen AI gives 200 credits for new users,
The 7 Best Seedance 2.5 API Providers
1. BytePlus: Best for Official API Access
BytePlus is the first option to check if you want official access and low base pricing.
It has the lowest no-video-input price in our comparison. The trade-off is lower concurrency and tighter rules around real-person references.
For developers who mainly use text, images, or non-human references, it is a strong starting point.
2. SeeGen AI: Best for Seedance-Focused Apps
SeeGen AI is only slightly more expensive than BytePlus at 720p.
Its main advantages are 480+ concurrency, real-person reference support, free credits, and pay-as-you-go API access. The current API also supports Seedance 2.5 alongside Seedance 2.0, HappyHorse, GPT Image 2, and Nano Banana models.
It makes the most sense when Seedance is a core part of your product and you expect to run many jobs.
3. Kie AI: Best for Multi-Model Development
Kie AI is more interesting when you want more than Seedance.
It provides one platform for many image, video, audio, and other AI models. That can reduce the work needed to manage several API providers.
Its Seedance 2.5 price is higher than BytePlus and SeeGen AI, but the wider model catalog can make up for that in multi-model apps.
4. Atlas Cloud: Another Multi-Model Option
Atlas Cloud also targets developers who want many models through one provider.
Its Seedance 2.5 pricing is competitive with other third-party platforms, and it supports real-person workflows in our comparison.
The main drawback is transparency. Public information about Seedance 2.5 concurrency and some video-input billing details is less clear.
5. PiAPI: Good for Video Reference Workflows
PiAPI costs $0.15/s at 480p and $0.35/s at 720p.
Its main advantage is easy-to-understand video billing. Reference video seconds cost half the normal output rate. That can be useful if your app uses motion references often.
6. WaveSpeed AI: Good for Scalable Concurrency
WaveSpeed is not the cheapest option, but its account tiers make it easier to increase concurrency as usage grows.
For individual developers, the most relevant range is from two concurrent jobs on a new account to 300 on the Silver tier.
It also has a broad model catalog, so it can work well for apps that use more than Seedance.
7. Fal AI: Best for a Broad AI Model Ecosystem
Fal is the most expensive provider in our base-price table.
But many developers use Fal because of its much wider model ecosystem, not because it is the cheapest Seedance provider. Its catalog covers many leading video and image models under one API platform.
If your app switches between several models, that convenience can matter more than the Seedance 2.5 price alone.
Which Seedance 2.5 API Is Best for You?
If Seedance 2.5 is the main model in your product, I would compare BytePlus and SeeGen AI first.
Choose BytePlus if official access and the lowest base price matter most.
Choose SeeGen AI if you need much higher concurrency, real-person references, or a way to test the platform before scaling.
If model variety matters more, Fal AI and Kie AI are worth a closer look. Both make more sense when Seedance is only one model in a larger image or video product.
PiAPI stands out for its simple reference-video billing, while WaveSpeed is useful when your concurrency needs may grow over time.
There is no single best Seedance 2.5 API for every developer. Base price matters for simple generation. For a real product, concurrency, video-input billing, real-person support, and access to other models can matter just as much.
Final Thought
For most developers, BytePlus is the best choice for official access and low base pricing, while SeeGen AI is a better fit when you need higher concurrency, real-person references, or easier testing. If your product uses many AI models, Fal AI or Kie AI may be more practical.
The best Seedance 2.5 API depends on your workflow, not just the lowest price per second.
