Bytedance volcano engine launches seedance 2.5 flash video model with doubled speed and lower cost

ByteDance Volcano Engine has officially released Seedance 2.5 flash, a new video generation model. This iteration is positioned as the model closest in performance to Seedance 2.5, offering double the generation speed and a reduced price point, making it a more cost-effective option for high-volume content creation. For text-to-video and image-to-video generation at 720P resolution, Seedance 2.5 flash costs approximately 0.99 RMB per second, marking a reduction of about 34% compared to Seedance 2.5. The model supports generating videos up to 30 seconds in length, with input capabilities including up to 10 images, 5 video clips, and 5 audio segments, available in 480P and 720P resolutions. While Seedance 2.5 flash offers high efficiency, the flagship Seedance 2.5 remains available for top-tier quality, supporting 1080P and 4K production via a Draft mode workflow. The new flash model is set to roll out across platforms such as Jimeng, LibTV, Updream, Creao AI, and TapNow starting immediately, with its API launching on Volcano Ark this coming Sunday, November 15.
