Seedream 4.5 - 2K and 4K image generator
Prompt-only generation or reference-led editing with up to ten references, a 2K or 4K switch, eight framings, seed, output count, and paid-model access — all as the live form shows them.
Seedream 4.5 examples at 2K and 4K
Six directions — portrait, landscape, product, poster, fashion, and food — shown as illustrations, not as a benchmark for realism, text, or consistency.
Why Seedream 4.5
The live form is the source of truth for prompt, reference, resolution, ratio, seed, and count. Judge every returned image against exactly what was submitted.
Prompt-only or reference-led runs
A run starts from a required prompt. Adding reference media switches the form into image-led mode, so the inputs at hand decide which mode fits the task.
One to ten references per run
Image-led mode takes between one and ten files. They steer the result without pinning identity, products, on-image text, backgrounds, or composition.
Three accepted formats, 10 MB each
References must be JPEG, PNG, or WebP files, and none may exceed 10 MB.
A 2K or 4K resolution switch
Output resolution is a two-way choice between 2K and 4K. Asking for the larger size does not make text more legible, facts more accurate, or faces more consistent.
Eight framings plus a seed field
Framing options run from 1:1 through 4:3, 3:4, 16:9, 9:16, 2:3, 3:2, and 21:9. A fixed seed makes A/B comparisons meaningful without promising identical output when anything else changes.
Count, credits, and time shown up front
The form exposes an output-count control; catalogue metadata lists 4 or 8 credits per run and an estimate near 120 seconds. Check the live debit before you submit.
Who uses Seedream 4.5's ten-reference, 2K–4K form?
Design, marketing, ecommerce, photography, and illustration work all fit the candidate workflows below, which exist to probe how references, resolution, framing, seed, and count behave — never to skip review.
Poster and ad layout tests
Try poster, ad, and social layouts, then check every word, logo, product detail, and disclosure obligation before anything ships.
Reference-driven product scenes
Feed product references into studio or lifestyle scenes and discard any output that changes packaging, labels, proportions, colors, or regulated claims.
Lighting and fabric studies
Compare how light, framing, fabric, faces, hands, and skin detail render — as studies, not as photography passed off as real.
2K against 4K side by side
Run the same setup at both sizes and log delivered dimensions, artifacts, text quality, and the credits charged.
Draft layouts that carry text
Treat language-bearing layouts as drafts and replace or verify every generated word before publication.
Same subject across scenes
Hold references constant across scenes and poses, and reject drift in the subject rather than promising consistency.
What a run costs and returns
Available in the form today, each priced in the same credits.
Includes a commercial licence for what you make.

Seedream 4.5 is one of the paid-access image workflows in this app. It runs prompt-only or with references, and the live form — not this page — defines the reference, resolution, ratio, seed, and count controls.
