Seedance 2.0 Pro - ByteSpike

Vendor: ByteDance Model ID: seedance-2.0-pro Capability: 1080p · up to 10s · text + image init · CJK prompts · async via tasks API Pricing: per second, pro tier (live rate) Seedance 2.0 Pro is ByteDance’s current video flagship. Adds an extended detail pass on top of 2.0 base — sharper texture work, cleaner character edges, better lip-sync on dialogue scenes. The right call when the clip is the deliverable, not iteration material. For drafts use Seedance 2.0; for hero shots use Pro.
