Render straight to 4K
1K for quick looks, 2K for most work, 4K when the frame has to survive a print crop or a wall. One Size chip, same prompt, same pass.
Seedream 4
Powered by Seedream 4 Image Generator
Write the frame and get it back at up to 4K, six takes at a time — or attach up to 10 references and edit, combine and restyle what you already have. The Size chip sets the pixels; the prompt sets the crop.
Everything Seedream 4 covers
Edit and combine from 10 references
Attach up to 10 images and describe the single frame they should become — change one element, carry a subject into a new scene, or fuse several frames together.
Six takes on one prompt
Ask for up to 6 images in one run and pick the keeper, instead of re-rolling a prompt one image at a time.
The prompt sets the crop
There is no aspect control to set. At one Size keyword an editorial landscape comes back near 3:2 and a panorama comes back far wider — the framing follows the words.

Frequently Asked Questions
How large can a Seedream 4 image be?
1K, 2K or 4K, set on the Size chips. There is no separate aspect control — the shape of the frame comes from the prompt.
How many images can one run produce?
1 to 6, on the Images slider. Each is a separate take on the same prompt, and each is priced as its own image.
How does reference editing work?
Attach 1 to 10 images and the run switches from text-to-image to editing. Write the prompt as the change — what to replace, what to leave identical — and the attachments are what it refers to.
Can a face or a product stay consistent across images?
That is what the references are for: attach the frame the subject already appears in and describe the new scene. Nothing is locked by a control — consistency comes out of the reference and the prompt.
Is there a negative prompt field?
No. Exclusions go inline at the end of the prompt, the way the examples here do: no text, no logos, no HDR, no harsh contrast.
Seedream 4 or Seedream 5?
Seedream 5 is the newer family and has its own app — Pro at 1K and 2K with 10 references, Lite at 2K to 4K with 14, one image per run. Seedream 4 is the one that renders up to 6 images at a time.
