字节跳动发布 Seedance 2.5 视频生成模型，单次生成时长翻倍至 30 秒，将陆续上线即梦 AI、豆包专业版，API 接入火山方舟，覆盖影视、广告、教育、工业制造及自动驾驶等场景。该模型延续多模态音视频联合生成架构，重点提升长叙事、多模态参考与编辑能力，推动 AI 视频从短片段迈向长内容创作。
字节跳动发布音频创作模型Seed Audio1.0，已在火山方舟开放测试。它打破传统影视音频需多模型分别生成人声、音效与环境声再人工拼接的冗长流程，实现声音场景一体化创作，确保叙事一致性，标志着AI音频生成进入完整声音场景新阶段。
2026年6月23日，火山引擎在夏季FORCE原动力大会上发布豆包视频生成模型Seedance2.5，计划7月上线。该模型实现30秒单段原生视频直出、50个全模态素材联合生成及保持画面一致性的局部编辑三大突破。总裁谭待表示，视频生成是通往世界模型的关键。
字节跳动火山引擎旗下火山方舟体验中心上线Seedance 2.0 Mini视频生成模型，主打高性价比，近期将开放API服务。该轻量化版本在保持高质量输出的同时，生成速度比同系列标准快速版更快，旨在服务更广泛的视频创作与规模化生产市场。
