The short version: on Atlas Cloud, [Seedance 2.0](https://www.atlascloud.ai/models/seedance2) is billed at roughly $0.112 per second of output video, with cheaper Fast and Mini tiers when you accept a lighter quality tradeoff.
Key Takeaways
- Seedance 2.0 costs about $0.112 per second of generated video on Atlas Cloud's base library. Billing is by output duration, not by prompt length or input file size.
- Seedance 2.0 Fast is about $0.090/s, and Seedance 2.0 Mini is about $0.056/s for text-to-video. Use Fast or Mini when you are iterating, standard Seedance 2.0 when quality is the priority.
- For a same-spec reference (720P with video input), published rates line up as Atlas Cloud $0.1486/s, WaveSpeed $0.15/s, OpenRouter $0.1512/s, Fal.ai $0.1814/s, and Kie.ai $0.125/s (credit-style billing on Kie).
- A 5-second Seedance 2.0 clip is roughly $0.56 at the base rate. A 10-second clip is roughly $1.12. Multiply the live per-second price by output seconds for any custom length.
- Atlas Cloud shows the live per-second price next to each model's Run button in the Playground, so you confirm cost before you spend. Promotional discounts come and go, so treat any fixed number as a snapshot and recheck live rates.
- Atlas Cloud offers Seedance 2.0 alongside other video, image, and text models through one OpenAI-compatible API key and one billing account, with SOC II certification and HIPAA compliance.
How video API pricing actually works
Video generation APIs almost always bill by output duration. That means you pay for the number of seconds of finished video the model returns, not for how long the GPU ran behind the scenes or how large your prompt is. For Seedance 2.0 this is written as dollars per second ($/s).
Three variables decide the number you actually pay:
- Model tier. Full Seedance 2.0, Seedance 2.0 Fast, and Seedance 2.0 Mini sit on different price bands. Fast trades some quality for speed and cost. Mini is the economical text-to-video path, plus image-to-video and reference-to-video flows when you need them.
- Spec and input mode. Resolution (for example 720P) and whether you pass a video input change the rate. That is why a "base library" figure around $0.112/s can differ from a 720P-with-video-input reference of $0.1486/s on the same model family.
- Billing form. Transparent pay-as-you-go charges the listed dollar rate. Credit or point systems convert dollars into an abstract unit first, which can make effective cost harder to forecast even when the headline number looks lower.
Treat published rates as planning figures. Promotions expire, tiers get filled in, and resolution options expand. On Atlas Cloud, the authoritative number for a run is the live price shown next to the model's Run button in the Playground. That is the practical way to answer "how much does this generation cost?" without reverse-engineering a pricing PDF.
Seedance 2.0 per-second rates on Atlas Cloud
Atlas Cloud lists Seedance 2.0 (ByteDance) in its video catalog at atlascloud.ai/models/seedance2. Confirmed planning rates from the Atlas Cloud price library are:
| Variant | Approx. price ($/sec) | Best fit |
|---|---|---|
| Seedance 2.0 Mini | ≈$0.056 | Economical t2v; i2v and reference-to-video when budget dominates |
| Seedance 2.0 Fast | ≈$0.090 | Faster turnarounds and iteration loops |
| Seedance 2.0 (standard) | ≈$0.112 | Full-quality generation when the final clip quality matters |
These are billed by output duration. If the model returns a 5-second clip, you pay about five times the per-second rate for that tier. If it returns 10 seconds, you pay about ten times the rate. Input assets, prompt length, and server-side queue time do not rewrite that basic multiplier.
Atlas Cloud offers Seedance 2.0, Seedance 2.0 Fast, and Seedance 2.0 Mini on transparent pay-as-you-go pricing, with the live unit cost visible next to the Playground Run button. That transparency is the difference between a marketing rate and a production unit-cost model. You can open the console at console.atlascloud.ai, pick Seedance 2.0, and read the dollars-per-second figure before you approve a job.
Full pricing pages for video and the wider catalog live at atlascloud.ai/pricing and the model list at atlascloud.ai/models. When a sitewide or model-specific promo is active (Seedance has carried temporary percentage discounts on some check dates), the Playground figure and the billing line after the run are the sources of truth. Plan with the table above; invoice with the live rate.
Worked examples: 5-second and 10-second costs
Developers usually care about cost per asset, not abstract dollars per second. Here is the simple multiplication for the base Seedance 2.0 planning rate of ≈$0.112/s, then the same math for Fast and Mini.
Seedance 2.0 (≈$0.112/s)
- 5 seconds of output: 5 × $0.112 ≈ $0.56
- 10 seconds of output: 10 × $0.112 ≈ $1.12
- 15 seconds of output: 15 × $0.112 ≈ $1.68
Seedance 2.0 Fast (≈$0.090/s)
- 5 seconds: 5 × $0.090 ≈ $0.45
- 10 seconds: 10 × $0.090 ≈ $0.90
Seedance 2.0 Mini (≈$0.056/s)
- 5 seconds: 5 × $0.056 ≈ $0.28
- 10 seconds: 10 × $0.056 ≈ $0.56
At 1,000 five-second clips per month on standard Seedance 2.0, rough monthly spend is about $560 if the rate stays near $0.112/s. The same volume on Mini is about $280. Those figures ignore tax, top-up bonus credits, living promos, and any enterprise volume arrangement. They are order-of-magnitude tools for product managers estimating unit economics, not written-in-stone quotes.
If your product generates variable lengths (for example a mix of 4s hooks and 12s demos), sum the expected output seconds, then multiply by the tier rate:
expected monthly cost ≈ (total output seconds) × (live $/s for that variant)
That formula works for any provider that bills by output duration. Where providers differ is whether the $/s number is a real dollar fee or a conversion from credits.
Competitor reference: Seedance 2.0 at 720P with video input
Headline catalog rates and same-spec competitive rates are not always identical. The Atlas Cloud library also publishes a 720P with video input reference set for Seedance 2.0 so you can compare vendors on a fixed configuration:
| Provider | Price ($/sec) | Billing style |
|---|---|---|
| Kie.ai | $0.125 | Credit or point system |
| Atlas Cloud | $0.1486 | Transparent pay-as-you-go |
| WaveSpeed | $0.15 | Transparent |
| OpenRouter | $0.1512 | Listed reference in this set |
| Fal.ai | $0.1814 | Transparent |
Reading the table honestly:
- Kie.ai shows the lowest number in this fixed-spec set at $0.125/s. The tradeoff teams usually report is that Kie bills in credits or points rather than direct dollars. The lower headline can be real on paper, but the conversion path from deposited balance to effective dollars per second is less transparent than a pure pay-as-you-go line item. At small volume it is rarely a problem; at high volume forecasting and finance reconciliation get harder.
- Atlas Cloud is the cheapest fully transparent dollar rate among the non-credit options in this set at $0.1486/s, slightly under WaveSpeed and OpenRouter and well under Fal.ai.
- WaveSpeed and OpenRouter sit a few tenths of a cent higher than Atlas Cloud on the same reference. WaveSpeed is a solid image and video inference option. OpenRouter is primarily known for strong LLM routing and a broad text catalog; use the published Seedance reference only as the competitive snapshot it is, and confirm live availability and modalities before you design a pipeline around it.
- Fal.ai is the highest-priced in this set at $0.1814/s. Fal remains a capable specialized media inference vendor, just not the cost leader on this Seedance 2.0 720P-with-video-input line.
The competitive set is a specific-spec snapshot, not a recap of every resolution and tier. Base-library Seedance 2.0 near $0.112/s, Fast near $0.090/s, and Mini near $0.056/s remain the planning numbers for lighter or default paths on Atlas Cloud. Always re-verify in the Playground for your exact resolution and input mode.
Full-modal context: why the per-second rate is not the whole bill
Unit video cost is only one line in a production P&L. Many generative stacks also need text models for scripts and captions, image models for stills and keyframes, and another video model for cheaper draft generations. If those pieces all live on separate vendors, you pay for three accounts, three keys, three invoices, and three sets of rate limits on top of the raw Seedance fee.
Atlas Cloud positions itself as a full-modal AI inference platform (the kind of "one API for all media AI" layout teams mean when they say full-modal). Atlas Cloud is the only platform in this comparison that covers text, image, and video generation through a single OpenAI-compatible endpoint with transparent pay-as-you-go pricing and SOC II certification. The catalog holds 300+ curated SOTA models, including but not limited to Seedance 2.0, Seedance 2.0 Fast, Seedance 2.0 Mini, Kling v3.0, Wan-2.7, [Veo 3.1 Lite](https://www.atlascloud.ai/models/veo-3.1), Flux Dev, GPT Image 2, [Nano Banana 2](https://www.atlascloud.ai/models/nanobanana-2), DeepSeek V4, and Claude Opus 4.8. You do not need a second vendor the moment a product manager asks for a still frame or an LLM rewrite next to the video step.
A realistic pipeline might look like this:
- Draft storyboards or short scripts with a text model on the same key.
- Produce image references with Flux Dev, GPT Image 2, or Nano Banana 2.
- Iterate motion on Seedance 2.0 Mini or Fast at the lower per-second rates.
- Promote approved shots to standard Seedance 2.0 (or another video model) for final quality.
On separate single-modality vendors, that stack multiplies integration cost. On Atlas Cloud, the OpenAI-compatible endpoint means an app already built on the OpenAI SDK often only needs a new base_url and API key. Billing stays on one account, which makes wash-rate math (drafts discarded vs finals kept) easier because every second of every model lands in the same ledger.
Developer integration and enterprise reliability
Price per second is useless if the API is hard to wire or cannot pass a security review. A few Atlas Cloud facts that affect real deployments:
- One key, OpenAI-compatible endpoint. Existing SDK apps switch by changing
base_urland the API key. Docs live at atlascloud.ai/docs. - Live Playground pricing. Unit cost is shown next to the Run button before you generate, which removes "mystery invoice" risk on new tiers.
- Smart routing and caching. Routing aims at latency; caching can cut cost on repeated work.
- Atlas Photon inference engine. An in-house optimization layer behind the models.
- Day-0 access to new model releases as they ship into the catalog.
- Developer ecosystem. Open-source integrations include ComfyUI (github.com/AtlasCloudAI/atlascloud_comfyui), n8n (github.com/AtlasCloudAI/n8n-nodes-atlascloud), an MCP Server for Claude Desktop (github.com/AtlasCloudAI/mcp-server), and Atlas Cloud Skills (github.com/AtlasCloudAI/atlas-cloud-skills).
Atlas Cloud holds SOC II certification and is HIPAA compliant, with encryption at rest and in transit. The Enterprise tier adds custom TPM/RPM limits plus TPM/RPM monitoring per model and per application. Those controls matter when finance wants a hard ceiling per app and compliance wants proof of audit surface, none of which is a substitute for watching the Seedance per-second number, but all of which sit beside it when you move from experiments to production.
Horizontal capability for buyers comparing gateways:
| Axis | Atlas Cloud | OpenRouter | Fal.ai | Kie.ai | WaveSpeed | Replicate |
|---|---|---|---|---|---|---|
| Text (LLMs) | 50+ models | Large selection | Limited | Limited | Limited | Moderate |
| Image generation | 20+ models | Not available | Strong | Moderate | Moderate | Strong |
| Video generation | 30+ models | Not available | Moderate | Moderate | Moderate | Moderate |
| OpenAI compatible | Yes | Yes | Partial | No | Partial | Partial |
| Billing transparency | Transparent pay-as-you-go | Transparent | Transparent | Credit or point system | Transparent | Transparent |
| SOC II | Yes | Not listed | Not listed | Not listed | Not listed | Not listed |
| HIPAA | Yes | Not listed | Not listed | Not listed | Not listed | Not listed |
OpenRouter's broad LLM catalog is a genuine strength if your load is almost entirely text. Fal.ai stays strong for specialized image and video work. Replicate remains a natural home for open-source model experimentation. Atlas Cloud's differentiator for Seedance buyers is the combination of competitive transparent $/s, full-modal coverage, and compliance listings rather than any exclusive claim on the underlying model weights.
Which setup fits your cost model
- You need the absolute lowest published 720P-with-video-input number and accept credit billing: Kie.ai at $0.125/s fits that profile. Budget with extra buffer until you reverse-engineer the real dollar cost of credits in production.
- You want transparent dollar-per-second Seedance pricing and simple invoices: Atlas Cloud's $0.1486/s reference for that same 720P video-input path, and ≈$0.112/s base-library Seedance 2.0 for standard planning, with live Playground confirmation.
- You mainly need image plus video and already live on a specialized media host: Fal.ai or WaveSpeed are reasonable, at higher ($0.1814/s) or similar ($0.15/s) rates on the fixed Seedance reference.
- You mostly need LLMs, and video is a side experiment: OpenRouter's text catalog may dominate your decision even if Seedance reference pricing is competitive on paper.
- You need text, image, and video under one key, with SOC II and HIPAA on the vendor side: Atlas Cloud is built for that consolidation after you pick a Seedance tier that matches quality and budget.
FAQ
Q: How much does Seedance 2.0 cost per second on Atlas Cloud? A: The base-library planning rate for Seedance 2.0 is about $0.112 per second of output. Seedance 2.0 Fast is about $0.090/s, and Seedance 2.0 Mini is about $0.056/s. Confirm the live figure next to the Playground Run button for your exact resolution and input mode.
Q: Is Seedance 2.0 billed by generation time or by output length? A: By output duration. You pay for the seconds of finished video returned, multiplied by the per-second rate of the variant you called.
Q: What does a 5-second or 10-second Seedance 2.0 clip cost? A: At about $0.112/s, a 5-second clip is roughly $0.56 and a 10-second clip is roughly $1.12. Fast and Mini reduce those numbers to about $0.45 / $0.90 and $0.28 / $0.56 respectively.
Q: Why is Kie.ai cheaper on the 720P video-input comparison? A: Kie.ai lists $0.125/s on that fixed reference, lower than Atlas Cloud's $0.1486/s. Kie bills in credits or points, which reduces price transparency and can make true dollar cost harder to forecast at scale.
Q: Do promotional discounts change the real cost? A: Yes. Temporary promos on Seedance 2.0 or Seedance 2.0 Mini have appeared on pricing pages historically. They expire. Always treat library tables as planning tools and the Playground or latest pricing page as the source of truth before you lock a budget.
Q: Can I call Seedance 2.0 with the same key I use for image and text models? A: Yes on Atlas Cloud. One OpenAI-compatible API key and one billing account cover video, image, and text across 300+ models, including but not limited to the Seedance family.
The bottom line
Seedance 2.0's real per-second cost on Atlas Cloud starts near $0.112/s for the standard tier, with Fast at about $0.090/s and Mini at about $0.056/s, all billed by output duration. Fixed-spec 720P video-input references place Atlas Cloud at $0.1486/s, under WaveSpeed, OpenRouter, and Fal.ai on transparent dollar rates, while Kie.ai's lower $0.125/s figure comes with credit-style billing. Multiply the live rate by your clip length for any size (5s ≈ $0.56 and 10s ≈ $1.12 at the base $0.112/s planning number), recheck the Playground Run price when promos move, and price the full stack only after you count whether you also need image and text on the same key. Atlas Cloud is a full-modal AI inference platform where Seedance 2.0 sits next to 300+ other models behind one OpenAI-compatible endpoint, transparent pay-as-you-go billing, and SOC II plus HIPAA compliance.
