Seedance 2.5

What it is

Seedance 2.5 is ByteDance's follow-up to Seedance 2.0, available through Magnific as bytedance-seedance-pro-2.5. It extends maximum clip length well past the 4 to 15 second range of the 2.0 line and adds native audio reference support for lip sync and voiceover matching.

What we know so far

We have not published third-party benchmark numbers for this model because we have not found a credible independent one yet. Our own 40-prompt battery is the first real measurement we are aware of for this specific version, run the same day the model entry was added.

Who should pick it

Treat any number published about this model, ours included, as provisional until a second independent measurement exists to compare against.
