字节跳动推出AI视频生成工具Seedance 2.5，在视频生成能力、素材支持和编辑精度上实现多项升级1。相比2.0版本，新版本支持原生30秒长视频一镜到底生成（非多段拼接），参考素材支持量从12个扩充至50个，包括30张图片、10段视频和10段音频1。此外，Seedance 2.5新增白模参考功能，可精准控制空间结构、人物姿态和镜头机位，同时支持局部场景编辑和时间戳精确控制1。
该工具已进入B端生产领域1。穹彻智能、微分智飞、徐工集团等企业已将Seedance应用于具身智能、飞行机器人、工业培训和自动驾驶等场景1。火山引擎总裁谭待表示，Seedance是字节AGI战略的核心基础设施，视频生成是构建世界模型的基础1。他同时指出，Seedance现有定价偏低，覆盖算力成本都困难1。
ByteDance has unveiled Seedance 2.5, an upgraded version of its artificial intelligence video generation tool that introduces significant technical enhancements and expands its applications beyond consumer use cases 1. The new version enables native generation of 30-second continuous videos, a substantial improvement over previous capabilities 1. The system now supports up to 50 multimodal reference materials—comprising 30 images, 10 video clips, and 10 audio segments—compared to 12 in the 2.0 release 1.
Additional upgrades include white-model referencing for precise spatial structure and character pose control, as well as localized scene editing with timestamp-level precision 1. According to Tan Dai, president of VolcanoEngine (ByteDance's cloud division), the pricing of Seedance remains challenging given production costs, as current rates struggle to cover computational expenses 1. Tan characterized video generation as a foundational capability for constructing world models and identified Seedance as a core strategic instrument in ByteDance's broader AGI initiative 1.
Beyond consumer applications, Seedance 2.5 has already been deployed across multiple enterprise sectors 1. Adoption spans embodied AI systems at Qiongche Intelligence, autonomous flying robots at Weifen Zhifei, and industrial training programs at Xuzhou Construction Machinery Group 1.
