Seedream: general design and distinct output modes
| Model | Tasks to try | Settings and limits here |
|---|---|---|
| Seedream 4.0 | Related characters, storyboards, series designs, or reference edits. | Exact dimensions and sequential sets; currently JPEG, no seed or format selector. With sequences off, use as single-image creation. |
| Seedream 5.0 Flash | Everyday creation, direction exploration, and multi-reference edits. | Preset/exact size and PNG/JPEG. No sequence, seed, or candidate count. |
| Seedream 5.0 Pro | Creation or reference edits with a preserved random starting point for comparison. | Exact size, seed, PNG/JPEG. No sequences or candidates; its dimension range differs from Flash. |
Usage, cautions and actual examples
Shared family names do not mean shared controls. 4.0 sequences are not available in Flash or Pro. These three currently have no web search, separate negative prompt, or manual thinking. Describe shared characters, each image's changes, and sequence order when using a supported series model.
Flash and Pro offer formats but no transparency or output-compression controls. A 4.0 sequence is not multiple 5.0 submissions. Recheck both inputs and output specifications when changing model/mode.
