Good to know
Billing
Runs bill your account credits at provider cost with 0% markup. The submit response includes the credit estimate; failed generations are refunded automatically. Add ?dryRun=1 to get the estimate without running anything.
Errors
Errors are always { "error": { "code", "message" } } with stable codes: unauthorized, model_not_available, invalid_parameter, insufficient_credits, rate_limited. A failed run is not an HTTP error — poll responses report status: "FAILED" with the reason.
What makes Seedream 5 Pro different
ByteDance's flagship image tier
Seedream 5 Pro is the top of the Seedream line — the tier ByteDance builds for fidelity. Where Seedream 5 Lite optimizes for price and Seedream 4.5 is the previous generation, Pro is the pick when detail, coherence, and edit quality matter more than squeezing every cent. On a Scenetra board all three run side by side, so you can compare them on the same prompt before committing.
Edit and compose with up to 10 reference images
Attach up to 10 input images and Seedream 5 Pro switches from generation to editing: restyle a shot, merge subjects from several sources, or apply a described change while preserving the rest. References can be uploads or outputs of other nodes on your board, which makes multi-step edit pipelines a matter of drawing edges.
Two honest resolution tiers
Pricing is simple: $0.035 per image at 1K (about 2 megapixels) and $0.07 at 2K (about 4 megapixels). Iterate at 1K, then re-run the winning prompt at 2K for delivery — on a board that's one field change on the node. Billed at provider cost with 0% markup, so the sticker price is the whole price.
Nine aspect ratios, including Auto
From cinematic 21:9 through square 1:1 down to vertical 9:16, Seedream 5 Pro covers every common canvas — and its Auto mode lets the model infer the right framing from your prompt and reference images, which is especially useful in edit workflows where the input already dictates the shape.

Frequently asked questions
What is Seedream 5 Pro?+
Seedream 5 Pro is ByteDance's most advanced image generation and editing model. It creates images from text prompts and edits or composes from up to 10 reference images, at 1K (about 2MP) or 2K (about 4MP) output. On Scenetra it runs as a node in the visual workflow editor, alongside Seedream 5 Lite and Seedream 4.5.
How much does Seedream 5 Pro cost?+
On Scenetra, Seedream 5 Pro costs $0.035 per image at 1K and $0.07 per image at 2K. You pay per generation from your credit balance — billed at provider cost with 0% markup, and no subscription gates the model.
What is the difference between Seedream 5 Pro and Seedream 5 Lite?+
Pro is the fidelity tier: higher-quality output at $0.035-$0.07 per image depending on resolution. Lite is the value tier at a flat $0.0275 per image at every resolution, and it can even output 4K. Pro is the pick for final client-facing work; Lite wins for volume and iteration. On Scenetra both sit on the same board, so you can run the same prompt through each and compare.
Can Seedream 5 Pro edit existing images?+
Yes. Attach up to 10 input images to the node and describe the edit in the prompt — restyle, combine elements from several sources, or change one detail while keeping the rest. Inputs can be uploads or outputs from other nodes on your Scenetra board.
What resolutions and aspect ratios does Seedream 5 Pro support?+
Two resolution tiers — 1K (about 2 megapixels) and 2K (about 4 megapixels) — and nine aspect ratios: auto, 21:9, 16:9, 3:2, 4:3, 1:1, 3:4, 2:3, and 9:16. Auto lets the model infer framing from your prompt and reference images.
Is Seedream 5 Pro free to try?+
Seedream 5 Pro is a paid model. On Scenetra you pay per image — from $0.035 — with nothing to cancel and no monthly plan required.
