SeeDance API FAQ
- How much does the SeeDance API cost?
- On UnificAlly, SeeDance video starts at $0.007 per second of output (1.0 Pro Fast at 480p, and the low end of 1.5 Pro) and runs up to $0.741 per second for 4K on 2.0 Pro. Billing is per generation with no subscription or monthly minimum, and you pay for the seconds you actually generate. Live rates are on the pricing page.
- What is the difference between SeeDance 1.0, 1.5, and 2.0?
- SeeDance 2.5 is the newest route and handles 4 to 30 second videos with up to 50 references. SeeDance 2.0 has Pro, Fast, and Mini routes and reaches 4K on Pro. SeeDance 1.5 Pro sits in the middle, while the 1.0 line is the cost-optimized option and starts at $0.007 per second.
- Which SeeDance model should I use?
- Use SeeDance 2.5 for 16 to 30 second videos or large multimodal reference sets. Start on SeeDance 1.0 Pro Fast or 2.0 Mini for drafts, and use 2.0 Pro when 1080p or 4K output matters more than duration.
- Is SeeDance 2.5 available?
- Yes. SeeDance 2.5 is live on UnificAlly as `bytedance/seedance-2.5`. It generates 4 to 30 second videos at 480p, 720p, or 1080p, with native audio, first/last frame control, and up to 50 multimodal references.
- Is SeeDance 2.0 free?
- There is no free tier. New UnificAlly accounts get a $0.50 signup balance to test it, and every SeeDance model runs in a browser playground. The balance covers a short test on 2.0 Mini and goes furthest on 1.0 Pro Fast at $0.007/sec. After that you pay per generation, with no subscription, and your balance never expires.
- Do I need a subscription to use the SeeDance API?
- No. UnificAlly is pay-per-use: you top up a balance and each generation deducts its exact cost. There is no monthly fee or seat license, your balance never expires, and SeeDance shares one API key and balance with every other video, image, audio and text model on UnificAlly.
