ByteDance releases Seedance 2.5 without published weights
- Sources: announcement, HN discussion
- Summary: ByteDance Seed announced Seedance 2.5, a video generation model, with no published weights and no stated training or evaluation method. The announcement describes single-take creation and flexible referencing as the product changes.
- Why it matters: Video generation quality claims are hard to check without weights or a stated method, so this is an API-only product change rather than a reproducible capability result.
