ByteDance keeps Seedance 2.5 closed as MiniMax plans H3 weight release

ByteDance rolled out Seedance 2.5 to Jimeng AI and Doubao Pro on July 31, 2026, after opening its enterprise API on BytePlus on July 16; Volcano Engine Ark API access is planned shortly.
Seedance 2.5 generates a continuous 30-second video in one inference pass, while Seedance 2.0 generated 15-second native clips and extended to 30 seconds by stitching generations together.
MiniMax H3 launched through the Hailuo AI consumer platform and a developer API; MiniMax said it plans to release the model weights within days, subject to applicable regulations.
If MiniMax releases H3's weights, developers can download, customize, and run the model on their own infrastructure without sending data through MiniMax servers.
Seedance 2.5 remains inside ByteDance's closed API and consumer products, while H3 is positioned for local deployment once its weights are released.
