Seedance 2.5 is ByteDance’s new-generation video creation model, launched on July 31, 2026. Building on the unified multimodal audio-video joint-generation architecture of Seedance 2.0, it shifts the focus from generating a single clip to completing a full creative work, with major breakthroughs in long-form storytelling, multimodal reference, and editing. The model generates up to 30 seconds of high-quality audio-video in a single pass, with improved shot transitions and scene changes for stronger continuity in longer videos. It supports multiple rounds of extension, so creators can build multi-minute content with a consistent audiovisual language, bringing a complete story to life in one take. Image, audio, and motion quality are all improved over the previous generation, resulting in more natural, polished visuals.

​
