Seedance 2.5 Flash is ByteDance's lighter, faster video model, released by Volcano Engine on November 12, 2026. It targets frequent creative iterations and batch production, with 480p/720p output, clips up to 30 seconds, reference inputs, synchronized audio-video generation and video editing. The company claims approximately 2× generation speed relative to flagship Seedance 2.5.
Reported text-to-video / image-to-video launch pricing is about CNY 0.44/s at 480p and CNY 0.99/s at 720p, about 34% below the flagship's matched launch rates. The Volcano Ark API is scheduled for November 15, 2026. As of November 14, that remains a planned API date, not evidence of already-open API access.

Seedance 2.5 Flash release date and API availability
The November 12 IT Home report states that Volcano Engine released the model that day. It reports a gradual rollout to Jimeng, LibTV, Updream, Creao AI and TapNow, with the API scheduled to open on Volcano Ark on November 15.
Release, creative-tool access and API access are separate milestones. A tool's model selector does not establish public API availability, a universal endpoint or an APIMaster model ID. We have not independently confirmed that every listed tool has enabled it for every account.
APIMaster will publish discounted channels as soon as they become available. This is our upcoming availability statement, not a promise of a particular launch-day discount or an automatic email notification.

These are count limits, not a complete API contract. They do not establish each input file's duration, total reference duration, upload size or every supported combination. Verify the published endpoint limits before preparing a large media batch.
Dreamina's official Flash page describes prompt and reference workflows, including Omni reference and first/last frames, and selection of 480p or 720p with synchronized audio. Product interface features should not be copied into API request fields until documented.
Seedance 2.5 Flash price: what does one video cost?
All amounts are CNY launch references for text-to-video / image-to-video. The comparison graphic lists:
| Resolution | Flash price / second | Ten-second Flash clip | Thirty-second Flash clip | Flagship price / second |
|---|---|---|---|---|
| 480p | 0.44 | 4.40 | 13.20 | 0.67 |
| 720p | 0.99 | 9.90 | 29.70 | 1.51 |
The matched-rate differences are approximately 34.3% at 480p and 34.4% at 720p. They explain the reported “about 34%” reduction. These are not confirmed APIMaster prices, reference-video quotes or an all-inclusive production budget.
The cheap Flash guide calculates batch costs and savings. Check exact settings, currency, fees and retries before comparing a future APIMaster quote with a launch reference rate.
What is different from flagship Seedance 2.5?
Flash prioritizes faster, less expensive creation at 480p and 720p. The flagship targets more demanding production, supports larger reference sets, and has a Draft workflow for choosing a preview before making a high-resolution final. The launch comparison lists flagship 1080p and a 4K offering, while marking 4K API access as upcoming.
The vendor describes Flash's quality as closest to Seedance 2.5 and better overall than Seedance 2.0. This article does not provide an independent quality benchmark or measured latency. Test your actual scenes before assigning a production batch.
For the full decision table, see Flash vs Seedance 2.5. Flash is a separate model tier, not another name for Seedance 2.0 Fast or the flagship's Draft mode.
Who should try Flash?
E-commerce and advertising teams: explore product motion, composition and multiple campaign variants without committing every attempt to a higher-resolution final.
Short-drama and storyboard teams: compare shot ideas, alternate actions and edits before polishing the selected sequence.
Developers building batch tools: prepare task tracking, explicit resolution selection and per-clip budgets. Compare completed, usable clips rather than submission speed alone. If the delivery needs 1080p or 4K, choose a supported flagship delivery path rather than expecting Flash to provide it.
Prepare for APIMaster's discounted Flash channels
Create an APIMaster account, prepare an API key, and configure https://apimaster.ai/v1. We will publish discounted Flash channels as soon as they become available, with the supported model ID and actual price. Registration does not reserve access or create an alert subscription.
For work today, check the live cards for seedance-2.5, seedance-2.0-fast and seedance-2.0-mini. Follow the selected model's documentation. Do not guess a Flash ID or send seedance-2.5 expecting Flash output.
