字节跳动Seed团队发布新一代视频创作模型Seedance2.0，采用统一的多模态音视频联合生成架构，推动AI视频生成从“单点突破”迈向“全能协作”的工业级应用阶段。相比1.5版本，新模型在复杂交互与运动场景下的可用率显著提升，通过出色的物理还原能力，攻克了双人花滑、多人竞技等高难度动作生成难题。
2026年春节期间，国产AI大模型赛道迎来密集发布潮，字节跳动、智谱、MiniMAX等头部企业相继推出新品，带动资本市场对AI应用板块热情高涨。其中，字节跳动发布的Seedance 2.0视频生成模型尤为瞩目，支持文本和图像输入，可生成长达60秒的多镜头视频，并实现了画质跨越，具备原生音频同步与出色的运镜规划能力。
字节跳动发布多模态视频生成模型Seedance2.0，性能强大引发关注。但知名博主Tim实测发现，仅凭一张照片，模型就能生成高度逼真的个人视频，引发对AI伦理和肖像隐私的担忧。
字节跳动内测多模态视频生成模型Seedance2.0，整合图像、视频、音频和文本处理能力，提供“导演级”控制精度，显著提升内容创作效率与质量。
