What each model is good for
Seedream 4.5 — highest resolution, most references
Reach for Seedream 4.5 when you need 4K output or want to feed in more than 10 reference images — useful for detailed key art, print-resolution stills, or scenes that draw on a larger set of character/location references at once.
Seedream 5.0 Pro — precision editing
Seedream 5.0 Pro trades top-end resolution for interactive editing: click a point or drag a box directly on the image to mark exactly what should change, then describe the edit in a prompt. This removes the guesswork of describing a location in text alone ("the object on the left" vs. literally clicking it) — the tradeoff is a 2K resolution ceiling and a 10-image reference cap.
Which one should you use?
Generating a new image from scratch or from a wide set of references, and want the highest resolution available? Use Seedream 4.5. Refining or precisely editing an existing image — moving, removing, or replacing a specific element? Use Seedream 5.0 Pro's interactive edit.
