Mixer AI
Seedream 4.5
Product scenes, characters and reference-based edits at 2K or 4K.
When to choose it
Think of Seedream 4.5 as a way to assemble an image: take a product from one photo, a person from another and place them in a chosen setting. It also creates images from scratch. Matching light, scale and object placement matters more than listing every possible style in one prompt.
- Generation and editing with several input images in one task.
- 2K and 4K options for images that need cropping or larger placement.
Modes and settings
- Text or up to 14 input photographs.
- 2K or 4K, 8 aspect ratios and 1, 2 or 4 results.
Price in coins
| Quality / size | Input | Coins / generation |
|---|---|---|
| 2K | Photo editing | 7 |
| 2K | Text | 7 |
| 4K | Photo editing | 7 |
| 4K | Text | 7 |
Coins are Mixer AI balance units. The table shows a base request without extra variations. Multiple results and new attempts can increase the total; check it before submitting.
What you can make
- A product scene assembled from several visual references.
- Storyboard frames of one character in different locations.
How to direct the result
- Specify which object comes from each photo and where it should go.
- Match scale, light and perspective across elements; list defining packaging or clothing details separately.
Example: a desktop still life
The watch from photo one rests on the closed notebook from photo two. Top-down view, pale wooden desk, soft light from the right. Preserve the watch face, strap, cover material and object scale. Add only one plain pencil beside them. No new logos or decorative lettering.
What to keep in mind
- References supply material for a composition, not a guarantee of unchanged pixels.
- Fine lettering, fingers and intersecting objects may need another edit.

Guides and comparisons using this model
FAQ
Can I start without a photo?
Yes. Describe the whole new scene: subject, composition, materials and light.
How many references can I use?
Up to fourteen. For a small scene, a few consistent images are often more useful than filling every slot.
Is 1K available?
This page offers 2K and 4K.
Can I edit a finished image?
Yes. Upload it, specify the change and separately identify what must remain.
How do I preserve product scale?
Describe its size relative to hands, a desk or another familiar object. Check perspective afterwards.
Must I rebuild everything for one detail?
Try using the chosen image as input for a local edit. Keep the previous version for comparison.
What changes the price?
It depends on version, quality and mode. The table prices one generation at the listed settings. Additional results, new attempts and chargeable input materials can increase the total.
Do I need a separate model subscription?
No. In Mixer AI, you top up one coin balance and use it for the tasks you need. You do not need a separate subscription to this model.
