Seedance 1.0 — First-Generation AI Video Model
Seedance 1.0 is the first-generation Seedance model, offering stable 720p video generation ideal for cost-sensitive batch workloads.
Overview
Seedance 1.0 is the first-generation video model in the ByteDance Seedance family. While surpassed by Seedance 2.0 in most scenarios, it remains a stable and reliable choice for applications that prioritize lower cost and faster iteration over cutting-edge visual quality.
The API interface is consistent with Seedance 2.0 — same endpoint, same parameter structure, same response format. When you're ready to upgrade to Seedance 2.0, you only need to swap the model field.
Features
- Text-to-video: Generate 720p video from text prompts
- Standard durations: 4–15 seconds
- Lower cost: Economical choice for high-volume batch workloads
