seedance 2.5 just went live on higgsfield. 33 days unlimited the actual upgrade isn't just longer clips. it's that fixing one wrong detail no longer means regenerating the whole scene. region-level edits fix the specific part, native audio generates in the same pass, and up to 50 references keep characters and style locked across a full 30-second continuous shot. that's the real cost saving most people miss, less time spent on full re-renders for small mistakes.(CyrilXBT)
