“发展速度太快了”！马斯克点赞Seedance 2.0，字节：还远不完美

Core Insights - The generative video model Seedance 2.0 from ByteDance is rapidly gaining popularity in overseas markets, with notable attention from Elon Musk, who commented on its fast development on social media [1][7]. Group 1: Product Launch and Features - ByteDance has officially launched Seedance 2.0, integrating it with Doubao and Jimeng products, and has opened the Huoshan Ark experience center for user trials [5][8]. - The model emphasizes capabilities such as original sound and image synchronization, multi-camera long narratives, and multi-modal controllable generation, targeting a broader range of creators and commercial content scenarios [5][8]. - Key features include: 1. Multi-modal input supporting text, images, audio, and video, allowing for mixed input of composition, actions, camera movements, effects, and sounds [8]. 2. Original sound and image synchronization with multi-track output for background music, sound effects, or voiceovers, ensuring alignment with visual rhythm [9]. 3. Multi-camera long narratives with automatic narrative logic parsing, generating shot sequences while maintaining character, lighting, style, and atmosphere consistency [10]. 4. Enhanced video editing and extension capabilities, reinforcing a "director-level control" workflow [11]. Group 2: Market Reception and Future Developments - The high exposure and rapid productization of Seedance 2.0 have intensified expectations for competition in the video generation sector [6]. - Musk's endorsement has broadened the model's visibility beyond the tech community to a wider audience interested in technology investments and products [7]. - ByteDance acknowledges that Seedance 2.0 is "far from perfect," with ongoing optimization needed in areas such as detail stability, multi-character matching, and complex editing effects [12]. - Compliance and usage boundaries are becoming clearer, with restrictions on using real human images or videos as reference subjects unless verified or authorized [15]. - A significant upgrade for the Doubao model and related generative models is scheduled for February 14, 2026, promising substantial enhancements in foundational model capabilities and enterprise-level agent functionalities [15].
