The expanded rollout of ByteDance’s Seedance 2.5 Flash video generation model began Nov 15, as the tool became available through the fal platform and the company’s own ModelArk hub. The model supports the creation of AI videos from text, images, or reference clips for durations between 4 and 30 seconds, and includes capabilities for video extension and native audio in 480p and 720p resolution.
Designed for high-volume work, the Flash version generates video at nearly double the speed of the standard Seedance 2.5 model. For 720p output, the service is priced at $0.152 per second, which is roughly 34% cheaper than the flagship version. The launch on fal and ModelArk follows an early access window provided via the Venice platform.
