Seedance 2.5 Flash Released: Doubled Speed, 34% Lower Price, Outperforms 2.0 Flagship

Beating AI News Flash: ByteDance's Volcano Engine has released Seedance 2.5 Flash, focused on faster and cheaper video generation. The new model generates twice as fast as Seedance 2.5, with visual quality close to the flagship version and overall performance even surpassing the previous-generation flagship Seedance 2.0.

Taking 720P text-to-video and image-to-video as examples, the generation price is approximately RMB 0.99 per second, about 34% cheaper than Seedance 2.5. At this price, generating a 30-second video costs about RMB 29.7.

Flash still supports video generation of up to 30 seconds, audio-video reference, and video editing, but its maximum resolution is only 720P, with a maximum input of 10 images, 5 videos, and 5 audio clips per session.

The new model will gradually launch on Jimeng, LibTV, Updream, Creao AI, and TapNow, with the Volcano Ark API scheduled to open on November 15.
