ByteDance launches Seedance 2.5 with 30-second single-run video generation
ByteDance
ByteDance officially launched Seedance 2.5, rolling it out to Jimeng AI and Doubao Pro, with API access on Volcano Engine's Ark platform to follow. The model generates a 30-second high-quality clip in a single run and accepts up to 30 images, 10 videos, and 10 audio clips as reference material.
Why it matters
Single-run 30-second generation with rich multimodal referencing pushes long-form AI video storytelling closer to production use, intensifying competition with MiniMax, Kling, and Sora.
Importance: 3/5
