What is Seedream 4.5?
This page sends requests to Seedream 4.5. It accepts a written brief, image-to-image edits, and several reference files, with 2K, 4K, or custom pixel sizes.
Choose a starting point
A clear reference hierarchy usually gives you a cleaner first pass. Say which details must stay and which can change.
Text to image
Write the scene from scratch. Include the subject, camera angle, light, materials, and anything that should not appear.
Image to image
Use one image as the anchor and ask for a focused change, such as a new crop, finish, wardrobe, or setting.
Multi-image reference
Give each file one role: identity, pose, palette, layout, or a product detail. Name those roles in the prompt.

Where 4.5 is useful
These examples show how to set up the inputs. Review every output before using it in a campaign or product listing.
Character consistency
Use identity and wardrobe references with a repeatable prompt skeleton for a character sheet or a set of scenes.
Posters and campaign frames
Combine a layout reference, palette reference, and copy-safe composition brief. Add final text in a design tool when typography must be exact.
Product photography
Give the product reference priority, then specify surface, light direction, camera distance, crop, and the objects that must not appear.
Seedream 4.5 prompt examples
Start with one of these briefs, then replace the subject, materials, and camera notes with your own.
Product studio set
Image to image · 4K · one reference
Use reference 1 for the exact product silhouette and finish. Create a clean studio product photograph on a pale stone surface, soft side light from camera left, controlled shadow, centered three-quarter angle, no logo changes, no extra objects, no readable text.
Character sheet
Multi-reference · 2K · four references
Use reference 1 for facial identity, reference 2 for hairstyle, reference 3 for clothing, and reference 4 for the muted color palette. Create a three-panel character sheet with front, side, and walking poses. Keep identity and clothing details consistent.
Editorial poster frame
Text to image · 4K · no references
Editorial poster composition for a night train journey, bold geometric crop, deep red and warm cream palette, one subject in profile, generous negative space for later typography, crisp paper texture, no fake logos, no readable text.
Single image or group
Use a group for a few related variations. Keep references plus max_images at 15 or fewer. Choose single mode when you need one result to review closely.
Seedream 4.5 FAQ
Which model does this page use?
Requests are locked to doubao-seedream-4-5-251128 and validated again on the server.
Can I use image-to-image and multiple references?
Yes. Upload 0–14 JPEG, PNG, or WebP references. Each file must pass the 30MB and dimension checks.
How does 4K image generation work here?
Choose the 4K preset or enter a custom WxH value. The server checks pixel count, dimensions, and aspect ratio before calling Ark.
When is group output enabled?
Turn on auto sequential image mode. References plus outputs must stay at 15 or fewer.
Why might generation be unavailable?
The server requires an Ark key, persistent storage, safety approval, and a safe positive Seedream 4.5 image credit price. Provider URLs are copied before they expire.
