Seedance 2.5 Flash FAQ

A faster, cheaper edition of ByteDance's Seedance 2.5 AI video model, built for quick takes and testing ideas. It makes video with synchronized sound at 480p or 720p, in clips up to 30 seconds, twice as fast as Seedance 2.5 by BytePlus's account, with results close to the full model.

ByteDance, through its Seed research team. It is sold to developers through BytePlus and offered to creators in ByteDance's Dreamina app.

The full name is Seedance 2.5 Flash. You may also see it called "Seedance Flash"; it is the same model. Don't confuse it with Seedance 2.0 Fast, an edition of the older model.

Yes. Like Seedance 2.5, it makes video and synchronized audio together.

No. It works at 480p and 720p, in clips up to 30 seconds. For 1080p, use the full Seedance 2.5.

It launched first on ByteDance's Dreamina app, worldwide, in early November 2026.

Not yet, but it is close. Since November 12, 2026, BytePlus ModelArk's price list shows Flash with its model ID and price, though the API doesn't accept calls to it so far. Our estimate is mid to late November 2026.

dreamina-seedance-2-5-flash-261115, as listed on BytePlus ModelArk's price list. Seedance 2.5's is dreamina-seedance-2-5-260628.

Today, in ByteDance's Dreamina app, where you pick it from the model list. Other apps, including Lumeta, can add it once ByteDance opens it on the BytePlus API.

Dreamina invites people to try more takes for free with Flash. On the API, BytePlus's price list shows no free tier.

BytePlus says it generates video twice as fast as Seedance 2.5. For a 5-second 720p clip that is about 2 minutes by our estimate, against a median 4 minutes 26 seconds for Seedance 2.5 on Lumeta.

BytePlus lists it at $7.00 per million tokens ($4.30 with a video input): about 34% less than Seedance 2.5 and the same as Seedance 2.0. That is about $0.76 for a 5-second 720p clip with sound, or $0.34 at 480p. Lumeta hasn't priced Flash yet; our estimate is about $0.49 for the 720p clip, where Seedance 2.5 costs $0.73.

Lumeta. A 5-second 720p Seedance 2.5 clip with sound costs $0.73 on Lumeta Max, less than on Higgsfield, Runway, Krea, OpenArt, Magnific, Artlist, Dreamina, fal, Replicate and WaveSpeed (prices checked November 9, 2026). Details at lumeta.ai/pricing#seedance.

Speed depends on each platform's queue and how it sends jobs to ByteDance. For fast Seedance we recommend Lumeta, which publishes its measured run times; see the speed page.

Flash is twice as fast and about 34% cheaper, per BytePlus, stops at 720p and takes fewer references (up to 10 images, 5 videos and 5 audio clips); Seedance 2.5 is slower, makes the most polished result and goes to 1080p. Use Flash to find the shot and Seedance 2.5 for the keeper.

We expect so for most clips: it is built on the newer Seedance 2.5, at exactly Seedance 2.0's API price. We'll confirm with side-by-side tests on launch day.

Both are fast editions at 480p and 720p. Flash comes from the newer 2.5 model; 2.0 Fast is on the API today and finishes a 5-second 720p clip in a median 2 minutes 28 seconds on Lumeta.

Both are fast 720p editions of their makers' latest models. We'll compare them on the same prompts once Flash reaches the API. Kling is available on Lumeta today.

We expect so, since Flash is built on Seedance 2.5. See the prompt guide.

Not yet. Once Flash reaches the API, Lumeta adds it, and Lumeta's MCP server lets AI assistants make Seedance videos on your account. Seedance 2.5 works that way today.
