Coming soonByteDance · announced Nov 12, 2026
Twice the speed of Seedance 2.5. About a third less per second.
Seedance 2.5 Flash is ByteDance's new tier for the takes you throw away: drafts, ad variations and everyday footage. It keeps 30-second clips, native audio and video editing, and trades 1080p for speed and price. This page tracks what is confirmed, what it costs, and when you can call it.
Not callable on APIPod yet. Your key, balance and the /v1/videos/generations endpoint stay the same when Flash arrives; only the model field changes.
What it is
ByteDance describes Flash as the model closest in quality to Seedance 2.5, with generation speed doubled and a lower price. The Seedance 2.5 family now has two tiers: the flagship for final shots, and Flash for everything you make on the way there.
ByteDance rates Flash above its previous flagship overall, and says prompt following, physical motion and audio stay close to Seedance 2.5.
At 720p a text-to-video or image-to-video clip lists at about ¥0.99 per second. That is the Seedance 2.0 rate, for a model that runs to 30 seconds.
Flash can change an existing video from a text instruction, so one approved take turns into several versions without starting over.

Speed is ByteDance's own comparison; there are no independent measurements yet. Prices are Volcano Ark list prices for a 5-second 16:9 clip without video input.
Pricing
Volcano Ark bills Seedance by tokens: ¥46 per million for Flash and ¥70 for the flagship at 480p and 720p, when the request carries no video input. The table converts that to the per-second cost of a 5-second 16:9 clip. Prices are the official list in CNY; APIPod's own rates will be published at launch.
| Resolution | Seedance 2.5 Flash | Seedance 2.5 | Difference |
|---|---|---|---|
| 480p | ¥0.44/s¥2.21 per 5s clip | ¥0.67/s¥3.36 per 5s clip | −34% |
| 720p | ¥0.99/s¥4.97 per 5s clip | ¥1.51/s¥7.56 per 5s clip | −34% |
| 1080p | Not supported | ¥3.74/s¥18.71 per 5s clip | — |
With a video in the request, the token price drops to ¥28 per million for Flash (¥42 for the flagship) and the input video's length is billed together with the output. Only successful generations are charged.
Estimate
Estimated at ¥0.99 per second, the official Volcano Ark list price for text-to-video and image-to-video. Requests with video input are billed differently.
Official examples
Six prompts published with the launch, one for each way of steering the model. Copy one, swap in your subject, and it is ready for the day the API opens.
One object, one light, one orbit. The cheapest way to judge how the model handles reflections and a slow camera move.
A matte black wireless earbud case rotates slowly on a white marble pedestal, the lid opening to reveal glossy earbuds inside, soft studio key light from the left, gentle reflections on the case, slow orbiting camera, clean minimal background, 16:9.
Tests whether on-screen text stays fixed while everything around it moves.
A summer sale poster comes to life: lemon slices float and spin around a glass bottle of sparkling lemonade, bubbles rise inside the glass, bold text "SUMMER SALE" stays fixed at the top, bright yellow background, light confetti drifting down, static camera.
A named camera move from wide to medium, with a character who stops and reacts.
A rainy neon alley at night, a detective in a long coat walks toward the camera, stops under a flickering sign and looks up, slow dolly in from a wide shot to a medium shot, puddle reflections, moody blue and pink lighting, cinematic tone.
Starts from a first frame and adds a line of dialogue, wind and waves in the same pass.
The woman brushes her hair from her face, looks toward the sea and says with a small laugh, "I could stay here forever." The wind keeps moving her hair and shirt. Slow push-in to a close-up, golden afternoon light, shallow depth of field. Waves, wind and distant gulls, no music.
A reference image keeps the face and outfit while the prompt moves her somewhere else.
The woman in @Image 1 walks through a sunny open-air market in a Mediterranean town, in the same cream linen shirt. She picks up an orange from a stall, smells it and smiles at the vendor. Handheld tracking shot at eye level, bright midday sun, warm natural colors, shallow depth of field. Market chatter and footsteps, no music.
Edits an existing clip: the car and the season change, the performance and the camera do not.
Change the red convertible to a sky-blue one and turn the scene into a bright spring day with wildflowers along the roadside. Keep the woman, her shirt, her movement and the camera move unchanged.
These are the example prompts published with the launch. Each card gets its clip once Seedance 2.5 Flash is live on APIPod.
Workflow
Flash and the flagship take the same prompt and the same references, so a take you approve on one can be sent to the other unchanged.
Run the idea at 480p or 720p with a short duration. You are checking framing, action, camera move and sound, not polish.
A static camera against a slow push-in. Morning light against dusk. One variable per take makes the better version obvious.
When a take works, stop editing. Save the prompt, the references and the settings together.
Need 1080p? Send the locked prompt to Seedance 2.5. If 720p is enough, the Flash take is already your final.
API
Flash will use the endpoint Seedance 2.5 already uses: submit a task to /v1/videos/generations, then poll its status. If you call Seedance 2.5 today, switching is a one-line change to the model field.

FAQ
Seedance 2.5 Flash is a faster, lower-cost tier of ByteDance's Seedance 2.5 video model, announced by Volcano Engine on November 12, 2026. ByteDance says it is the model closest in quality to Seedance 2.5, with generation speed doubled. It produces clips of up to 30 seconds at 480p or 720p with native audio, and supports video editing.
It was announced on November 12, 2026 and started rolling out the same day on ByteDance's Dreamina and partner apps including LibTV, Updream, Creao AI and TapNow. The API opens on Volcano Ark on November 15, 2026.
Not yet. APIPod is adding Seedance 2.5 Flash to the same /v1/videos/generations endpoint that serves Seedance 2.5, so an existing integration will only need a new model ID. Until then, Seedance 2.5 and Seedance 2.0 are live on APIPod.
On Volcano Ark, Seedance 2.5 Flash lists at ¥46 per million tokens without video input, against ¥70 for Seedance 2.5. For a 5-second 16:9 clip that works out to about ¥0.44 per second at 480p and ¥0.99 per second at 720p, roughly 34% below the flagship. APIPod's prices will be published when the model goes live.
Flash is about twice as fast and roughly a third cheaper, and it stops at 720p with up to 10 images, 5 videos and 5 audios as references. Seedance 2.5 adds 1080p, Draft mode, video extension and a larger reference budget of 30 images, 10 videos and 10 audios. Use Flash for drafts and volume, and Seedance 2.5 for the final shot.
ByteDance says Flash is better overall than Seedance 2.0, its previous flagship. Flash also doubles the maximum clip length from 15 to 30 seconds at the same 720p list price of about ¥0.99 per second. Seedance 2.0 still has the edge on resolution, with output up to 4K.
A single generation runs up to 30 seconds. Output is 480p or 720p; there is no 1080p or 4K. One request accepts up to 10 images, 5 videos and 5 audio clips as references.
Create an API key, build against Seedance 2.5 on the same endpoint, and keep the model ID configurable. Save a small set of prompts that look like your real work and record time, cost and pass rate on the model you use now, so you can tell what Flash improves on day one.
Set up your key and build on Seedance 2.5 now. When Flash goes live on APIPod, you change one field.
