Seedance 2.0 Fast prioritizes generation speed and lower cost while retaining Seedance 2.0's multimodal inputs, synchronized audio, professional camera movements, and in-video text rendering.

const result = await generateVideo({ model: 'bytedance/seedance-2.0-fast', prompt: 'A serene mountain lake at sunrise.'});Seedance 2.0 Fast is the speed-optimized companion to Seedance 2.0, released April 14, 2026 as part of the second-generation ByteDance Seedance video lineup. It preserves the full capability set of the standard variant (text-to-video, image-to-video, multimodal reference-to-video, and video editing and extension) but prioritizes generation speed and lower cost over peak output quality.
For iterative creative workflows, draft generation, and high-volume content pipelines, faster turnaround compounds into significant time savings. Teams iterating on prompts, exploring storyboards, or generating dozens of video variants for A/B testing benefit from the Fast tier's lower per-clip cost while retaining the same input flexibility.
Like the standard variant, Seedance 2.0 Fast supports synchronized multilingual audio, professional camera movements, multi-shot composition, in-video text rendering, and complex scenes with facial expressions and physical interactions.
AI Gateway applies no markup on video generation for Seedance 2.0 Fast: the rate matches the direct ByteDance provider price. Set the model to bytedance/seedance-2.0-fast and call it through the AI SDK's generateVideo function.
