ByteDance's video model that generates video and synced audio together from text, image, or reference clips.
Seedance 2.0 is ByteDance's video generation model, built to produce a video and its matching audio in one pass instead of adding sound afterward. It accepts text prompts, reference images, or existing video as input, and gives control over camera movement, lighting, and performance within the generated clip. ByteDance's own site offers a web demo and API access, but does not publish direct pricing; third-party API resellers such as OpenRouter and fal.ai list per-second rates that scale with resolution, from roughly 480p up to 4K output.
ByteDance bills through the API by the second rather than a flat monthly fee. The lowest published rate is about $0.067 per second of 480p video with audio (roughly $4/minute), rising to about $0.78 per second at 4K; ByteDance's own product page does not show a price table.
Use tool ↗A capable video-and-audio generator from a company with the compute to back it, offering finer input control than a plain text box. The tradeoffs are opaque self-serve pricing on ByteDance's own site and per-second API costs that climb fast at higher resolutions.
Watch out: Actual billing happens through whichever API reseller you pick, not through ByteDance directly, so rates and terms vary by provider.
