AI NewsSeedance 2.5: ByteDance's 30-Second Video Model With Native Audio
ByteDance released Seedance 2.5 on July 31, 2026. It generates 30-second video clips with audio in a single pass, supports multi-turn extension, and accepts up to 30 images, 10 videos, and 10 audio files as reference per input. Google's Gemini Omni Flash currently caps output at 10 seconds and does not yet support audio reference uploads or scene extension in the Gemini API. Seedance 2.5 launched on Jimeng AI and Doubao Pro; BytePlus ModelArk published a Seedance 2.5 tutorial on August 7, 2026, but regional API availability should be verified before building a production dependency.
