## 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.

### Photorealistic Portrait

### 4K Landscape

### Studio Product Shot

### Bilingual Poster With Text

### Fashion Editorial

### Food & Lifestyle

## 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.

## Seedream 4.5 2K and 4K form FAQ

Input modes, the ten-reference cap, formats, 2K versus 4K, framings, seed, count, paid access, credits, time, rights, and what to review.

### What is Seedream 4.5?

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.

### Can I run Seedream 4.5 without a reference image?

Yes. A prompt alone is enough. Attaching one or more references switches to image-led mode; ratio, resolution, seed, and count stay available in both.

### What is the reference limit for Seedream 4.5?

Between one and ten JPEG, PNG, or WebP files, each at most 10 MB. They guide the run; they do not lock it.

### Does Seedream 4.5 output 2K or 4K?

Both are selectable. After a run, inspect the delivered dimensions, compression, fine detail, and any rendered text rather than trusting the label.

### Which framings does the Seedream 4.5 form offer?

Eight: 1:1, 4:3, 3:4, 16:9, 9:16, 2:3, 3:2, and 21:9.

### What does a Seedream 4.5 run cost?

The catalogue lists it as paid access at 4 or 8 credits per run; the form shows the live estimate before you submit.

### Why set a seed or a count on Seedream 4.5?

A seed keeps comparisons controlled; a count returns several candidates at once. Neither promises consistency, and a higher count raises the debit.

### Is Seedream 4.5 output covered by the commercial license?

On any paid plan, yes — this app's commercial license applies. Rights to your prompts and references, the platform terms, and the final use remain yours to clear.

### What should I check in a Seedream 4.5 result?

Prompt adherence, identity, anatomy, text, product details, background, crop, delivered dimensions, and any unintended change to the source.

### What limits should I check before using Seedream 4.5?

Generated output from Seedream 4.5 can contain visual, audio, or factual errors. Review each result before publishing, and upload only material you are authorized to use. Where the form accepts a reference image, supported files are JPEG, PNG, WebP up to 10 MB each.

### What happens to the files I upload to Seedream 4.5?

An upload is stored against your own account, not pooled with other people's. Deleting the account removes it: the control is in Settings under Security, the request is confirmed by email, and the erasure removes the stored objects it owns. How long anything else is kept, and which processors handle it, is stated in the privacy policy.

### Can I use what Seedream 4.5 makes commercially?

Every paid plan includes a commercial licence for what Seedream 4.5 makes; the free tier is for personal use.
