Seedance 2.5 is the latest generation of the Seedance family of unified multi-modal AI video generation models. As the successor to Seedance 2.0, it not only doubles the single-shot generation time to 30 seconds but also supports up to 50 multi-modal reference elements. It can output native 3840×2160 4K ultra-high-definition video without the need for external scaling steps. The biggest technical highlight of this product is its ability to organically integrate text, images, videos, and audio, outputting a complete film with perfectly synchronized visual and audio effects in a single generation. The prompt comprehension has improved by about 20%. It is positioned as a professional productivity tool for advertising, e-commerce, short-form storytelling, and synthetic data fields in embodied intelligence and autonomous driving. Currently, the model is in the Preview phase and open for a waiting list, while the current 2.0 version of the website offers different subscription plans from Starter (monthly $19.9 annually) to Ultra (monthly $149.9 annually).
