Seedream 4.0 and Nano Banana 2 overlap on the basic image workflow: choose a ratio, write a direction, and optionally provide a source image. Their clearest catalog difference is the listed resolution range.
At-a-glance comparison
| Catalog label | Resolution | Ratios | Source image | Reference images |
|---|---|---|---|---|
| Seedream 4.0 | 1080p, 2K, 4K | 1:1, 16:9, 9:16, 4:3, 3:4 | Supported | Not listed in the current catalog |
| Nano Banana 2 | 1080p | 1:1, 16:9, 9:16, 4:3, 3:4 | Supported | Not listed in the current catalog |
When Seedream 4.0 is a sensible starting point
Choose Seedream 4.0 when the listed output size matters to the workflow: a high-resolution still, a large poster draft, a product frame, or a keyframe that will be inspected closely. The catalog lists 2K and 4K options, but the selected setting does not guarantee that every prompt will contain the same level of detail or that every output is ready for final publication.
Use the Seedream 4.0 model page to see the current settings and a repeatable three-step workflow.
When Nano Banana 2 is a sensible starting point
Nano Banana 2 is a useful starting point for quick 1080p concept iteration, especially when you want to revise a source image or explore several compositions before committing to a larger output. Keep the brief focused: subject, setting, composition, light, and intended use.
The provider-facing identifier in the connected catalog includes a suffix, while the user-facing label is “Nano Banana 2.” MotionVeo uses the display label on this page and does not treat the opaque identifier as a public product name.
Shared ratios, different jobs
Both models currently list 1:1, 16:9, 9:16, 4:3, and 3:4. Pick the ratio based on where the image will live. A product page may need 1:1 or 4:3; a landscape keyframe may need 16:9; a mobile-first concept may need 9:16. Do not generate a wide frame and assume a later crop will preserve the subject.
Simple selection rule
- Need the highest listed resolution? Start with Seedream 4.0.
- Need a fast 1080p concept pass? Start with Nano Banana 2.
- Need a source-image revision? Both currently list source-image support.
- Need reference-image inputs? They are not listed for either model in this snapshot; verify Studio before planning around them.
How to compare outputs fairly
Use the same prompt, source image, ratio, and visual goal. Render a small set, inspect composition and edge quality at the intended display size, and record what you would change next. A catalog capability tells you what a model can be asked to do; it does not replace inspecting the actual result.
