SeeDream API FAQ

How much does the SeeDream API cost?

On UnificAlly, SeeDream images start at $0.024 per image (SeeDream 4.0 at default settings) and run up to $0.06 per image on SeeDream 5.0 Pro at 2K. Billing is per generation with no subscription, and live rates are on the pricing page.

What is the difference between SeeDream 4.0, 4.5, and 5.0?

SeeDream 5.0 is the current generation: Pro for top quality with up to 10 reference images, Lite for cheaper volume work with up to 14 references. SeeDream 4.5 improves reference handling and 4K output over 4.0, and 4.0 is the cheapest route in the family.

Which SeeDream model should I use?

Start on SeeDream 4.0 or 5.0 Lite for drafts and batch pipelines. Move to 5.0 Pro when the brief needs the best reference fidelity and output quality. 4.5 is the middle ground with 4K output at a 4.x price.

Do SeeDream models support reference images?

Yes — every SeeDream model accepts reference images to lock a subject, product, or style: up to 10 on 5.0 Pro and up to 14 on 5.0 Lite and 4.5.

Is SeeDream free?

There is no free tier. New UnificAlly accounts get a $0.50 signup balance, enough for 20 images on SeeDream 4.0 ($0.024 each) or 17 on 5.0 Lite ($0.028). Every model below runs in a browser playground. After that, you pay per generation with no subscription, and your balance never expires.

Do I need a subscription to use the SeeDream API?

No. UnificAlly is pay-per-use: you top up a balance and each generation deducts its exact cost. There is no monthly fee, your balance never expires, and SeeDream shares one API key and balance with every other video, image, audio and text model on UnificAlly.

How do I get a SeeDream API key?

Create a UnificAlly account and copy your key from the dashboard. One SeeDream API key covers every model in the family (5.0 Pro, 5.0 Lite, 4.5, and 4.0) plus every other image, video, audio and text model on UnificAlly, and new accounts get a $0.50 signup balance to test it.

Is it SeeDream, Seedream, or See Dream?

ByteDance writes it Seedream, one word; UnificAlly styles it SeeDream. Searches for "see dream", "seed dream", or "seedream 5" all refer to the same ByteDance image family on this page, with SeeDream 5.0 Pro and 5.0 Lite as the newest generation.
