seedance-pro - ByteSpike

seedance-pro is the current ByteDance Seedance flagship — strong on fidelity, prompt adherence, and motion stability, and it supersedes seedance-1.5-pro. Strong on Chinese aesthetic and East-Asian subject quality. The default Seedance tier for new projects. Pricing: $0.06 / second of generated footage — see the rate card. Failures don’t bill.

When to use

Chinese-market video — products, ads, posters where Chinese aesthetic and East-Asian subject quality matter.
DOSIA generate_video — main brain reaches for this for Chinese-market video when permissioned.

When not to use:

Sora-grade physics / motion is the bar — sora2 or sora2-pro.
Fastest possible wall-clock — seedance-pro-fast for the same model with faster runtime, or seedance2-fast for the cheapest Seedance tier.

seedance-pro-fast — same model, faster runtime
seedance2 — newer Seedance 2 tier
sora2 — OpenAI alternative

seedance-1.5-pro seedance-pro-fast
