Checked 2026-11-14. Flash launched November 12, and the reported Volcano Ark API opening is planned for November 15, 2026. APIMaster has not yet listed Flash. We will publish discounted Flash channels as soon as they become available.
The quick table uses USD per generated second at 720p without reference-video input for existing APIMaster models, and CNY launch references for Flash. Counts cover enabled public, non-exclusive routes; existing reference prices are marketplace benchmarks. The live model card takes precedence.

Price: Flash launch references vs discounted 2.0 Fast
Flash's reported text-to-video/image-to-video launch references are CNY 0.44/s at 480p and CNY 0.99/s at 720p. These are not APIMaster Flash quotes. Fast's current starting rates are USD 0.03371625/s at 480p and USD 0.072503424/s at 720p. Different currencies must be converted at the same exchange rate before comparing the two models; we do not subtract CNY figures from USD figures.
What does the Fast discount save on 100 videos?
Amounts below are USD, for output generation without reference-video input. Each batch contains 100 ten-second clips; calculations use unrounded prices. The benchmark is the Fast rate in the marketplace, not Flash pricing.
| Resolution | Fast price / second | 5-second clip | 10-second clip | 100 × 10s | Saving vs Fast benchmark |
|---|---|---|---|---|---|
| 480p | From $0.033716 | $0.17 | $0.34 | $33.72 vs $56.25 | Save $22.53 (~40.1%) |
| 720p | From $0.072503 | $0.36 | $0.73 | $72.50 vs $120.96 | Save $48.46 (~40.1%) |
At 720p, the starting budget for 1,000 ten-second clips is $725.03, versus $1,209.60 at the reference rate: $484.57 saved. Actual cost depends on the selected route and successful billable attempts; reference inputs, extra attempts and optional processing can add charges. Pick a short test before scaling.
Speed: is Flash faster than Seedance 2.0 Fast?
There is no verified Flash-versus-Fast latency ratio in the sources used here. The Flash launch claim is approximately 2 × the speed of flagship Seedance 2.5, not 2 × the speed of Seedance 2.0 Fast. The words “Flash” and “Fast” are model names, not comparable latency measurements.
For a useful test, hold the prompt, image, duration, resolution and aspect ratio constant. Measure submission to completed, downloadable video, including queue time. Compare median and slower-tail completion times as well as usable output rate. Do not count an accepted task ID as a finished video. Until you have access to both models, Fast's practical advantage is that its API and prices are already available on APIMaster; that is an availability advantage, not proof of a faster generation engine.
Capabilities: when can Fast replace Flash?
| Requirement | Seedance 2.5 Flash | Seedance 2.0 Fast on APIMaster |
|---|---|---|
| Resolution | Announced 480p / 720p | Documented 480p / 720p |
| Output duration | Up to 30 seconds announced | 4–15 seconds per request |
| Image / video / audio references | Up to 10 / 5 / 5 announced | Up to 9 / 3 / 3 documented |
| Draft | Not supported in the launch comparison | Not supported |
| Current APIMaster access | Not yet listed | Available; model ID seedance-2.0-fast |
These columns compare Flash's announced capabilities with Fast's current APIMaster API limits. They are not a promise that the endpoints accept identical requests. Fast video and audio references have additional duration limits; reference audio requires an image or video. Fast cannot produce one native 30-second clip by setting duration: 30. Two shorter clips require separate generations and editing, and continuity is not guaranteed.
Which should you use for ads, product videos and a deadline?
Need a five- or ten-second 480p/720p clip now: choose Fast, confirm its current market price and run a short test. It is a practical option for ad variations, product motion concepts and short social clips while Flash is unavailable.
Need one continuous clip longer than 15 seconds or more references: Fast is not a complete substitute. Evaluate Flash once its API is available, or another model whose documented limits fit the job.
Need the new model's visual behavior: use the same scene to evaluate it after gaining access. Flash's “near flagship” quality statement is a vendor claim, not our independent win-rate comparison against Fast. A lower Fast bill does not prove equal quality, and a newer Flash name does not prove better results for every prompt.
Use Seedance 2.0 Fast while waiting for Flash
Register, create a key and use https://apimaster.ai/v1 with seedance-2.0-fast. Start with POST /videos/generations, duration: 5, resolution: "720p", aspect_ratio: "16:9", generate_audio: true and your prompt. Keep the returned task ID, poll GET /videos/{task_id} and download the completed original file. If submission times out, check the original task before resubmitting.
Fast is a separate model, not a hidden Flash endpoint. Once Flash discounted channels are published, use the actual listed Flash ID and limits; do not relabel a Fast response as Flash.

FAQ
How much is Seedance 2.0 Fast while I wait for Flash?
At the November 14 snapshot, Fast starts at $0.033716/s at 480p or $0.072503/s at 720p. A ten-second 720p generation starts at about $0.73 without reference-video input.
Is Fast 40.1% cheaper than Flash?
That percentage compares APIMaster Fast with the Fast marketplace benchmark, not with Flash. Flash launch references are in CNY; Fast prices here are in USD.
Does Flash generate twice as fast as 2.0 Fast?
The reported 2 × comparison is against flagship Seedance 2.5. No controlled Flash-versus-2.0-Fast timing result is supplied here.
Can Fast make a 30-second clip or become Flash later?
Fast supports 4–15 seconds per request in the current API. It remains a distinct model. APIMaster will publish discounted Flash channels as soon as they become available.
