Seedance v1.0 Pro Fast delivers Seedance 1.0 Pro-quality 1080p video generation at approximately 3x faster throughput and 72% lower cost than standard Pro, making it the default for latency-sensitive and cost-conscious production pipelines.
import { experimental_generateVideo as generateVideo } from 'ai';
const result = await generateVideo({ model: 'bytedance/seedance-v1.0-pro-fast', prompt: 'A serene mountain lake at sunrise.'});Seedance v1.0 Pro Fast targets maximum generation speed and cost efficiency while staying in the Pro quality tier. It generates approximately 3x faster at 72% lower cost per clip than Seedance 1.0 Pro while maintaining 1080p output at 24 fps for the same two- to 12-second duration range.
The model supports both text-to-video and image-to-video input modes, accepts 480p, 720p, and 1080p output resolutions, and offers the same seven aspect ratios as Pro. It renders detail in facial features and hair textures, reproduces styles consistently from reference images, and handles physically complex motion scenes. Prompt comprehension matches standard Pro for action intentions, character relationships, and scene changes, with lower wall-clock time.
For product teams building user-facing generation features, Seedance v1.0 Pro Fast expands what you can run synchronously. At 3x the speed of standard Pro, many requests that previously required async job queuing and webhooks fit inside acceptable synchronous windows. That simplifies application architecture and shortens wait times.
