Seedream 5 Pro is ByteDance's image model for precise work. Its standout is region editing: point at an area with a box and change only that. It also renders text in many languages and combines up to 10 references.

## When to use it

- Changing one part of a product photo, such as a cap colour, while nothing else moves.
- Text in languages other than English.
- Information graphics and photoreal textures.

## How to prompt it

- Give each element its own clause: format, subject, composition, lighting, text, style.
- Place the light by direction and quality; it matters more than style words.
- Put exact text in quotes and say where it goes.
- Name references by number and job: "Image 1 for the product, Image 2 for the outfit".
- To edit a region, add a box after the image name: `<bbox>x1 y1 x2 y2</bbox>`, on a 0 to 999 grid from the top left. Then list what must stay the same.
- Keep prompts under about 600 words; longer ones lose details.

## Example

A region edit: the box marks the dropper cap, and only the cap changes.

Input: product photo: ![An amber glass serum bottle with a black dropper and a cream label reading SERUM 01, on a light grey background](https://sloosh.ai/docs/in-bottle.webp)

->

Result: ![The same amber SERUM 01 bottle, now with a brushed gold dropper cap](https://sloosh.ai/docs/m-seedream-5-pro.webp)

_4:5, 2K, Enhance off._

**Prompt**

```text
Change the dropper cap in Image 1 <bbox>400 145 600 375</bbox> to brushed gold metal. Keep the exact bottle shape, the amber glass, the "SERUM 01" label, the camera angle, the background and the studio lighting.
```

## Frequently asked questions

### What is Seedream 5 Pro best for?

Seedream 5 Pro is best for changing one part of a product photo while nothing else moves, such as a cap colour, and for text in languages other than English, information graphics and photoreal textures. ByteDance recommends the Pro tier for precise marker edits and multilingual text.

### How do I edit just one part of an image with Seedream 5 Pro?

Name the image and add a box around the area: "Change the dropper cap in Image 1 <bbox>400 145 600 375</bbox> to brushed gold metal." Coordinates run 0 to 999 from the top left. Then list what Seedream 5 Pro must keep, such as the bottle, label, angle and lighting.

### Which languages can Seedream 5 Pro write in images?

Seedream 5 Pro renders text in many languages, including Arabic, Russian, Thai, Korean, Turkish and Filipino. Put the exact words in quotes, written in the target language, and say where they go. Without quotes, Seedream 5 Pro's text can come out garbled.

### How long should a Seedream 5 Pro prompt be?

Keep a Seedream 5 Pro prompt under about 600 English words; ByteDance says longer prompts scatter attention and the model drops details. Sloosh also caps the prompt at 5,000 characters. Give each element its own clause: format, subject, composition, lighting, text, style.

### What resolution does Seedream 5 Pro make in Sloosh?

Seedream 5 Pro makes 1K or 2K images in Sloosh, with 2K as the default. Draft at 1K while you try ideas, then render the final at 2K. For 4K, use [FLUX 3 Image](https://sloosh.ai/docs/flux-3-image.md) or [Nano Banana Pro](https://sloosh.ai/docs/nano-banana-pro.md) instead.
