What the table does not settle
The generational gap in one sentence: Seedance 2.5 publishes single takes of up to thirty seconds [1], while Sora 2 published takes of up to twenty seconds before OpenAI shut its API down on 2026-09-24 [2] — so this pairing can only be judged on archived Sora output until voting starts.
On the published specs the models were tuned differently: Seedance 2.5 leans on reference-heavy work with up to fifty inputs [1], while Sora 2 leaned on multi-shot stories from text alone. A blind vote between archived Sora clips and fresh Seedance clips would still be a fair preference signal — voters judge the screen, not the roadmap.
