On October 23, 2026, Volcano Engine, a subsidiary under ByteDance, officially rolled out its latest video generation model, Seedance 2.5 4K. This iteration, honed through specialized training, excels in rendering facial expressions, nuanced movements, and intricate visual details with remarkable precision. It supports a 10-bit color depth, significantly enhancing texture, color gradation, and gradient transitions. When it comes to reference generation and video editing, the model ensures superior clarity and consistency of materials.

A notable feature of Seedance 2.5 4K is its cost-effective creative process. Users can initially validate their storyboards using 480P samples before proceeding to produce high-resolution 4K final versions. This approach minimizes the expenses associated with creative exploration. Currently, the model is accessible for trial use by a select group of enterprise customers, with plans to progressively broaden its availability in the future.
