Seedream 4.0 is developed by ByteDance, the parent company of TikTok, as part of their SEED AI research program.
## Capabilities
Complex edits — including detailed product or character transformations — completed in one generation, reducing iteration time.
Maintains character identity, product appearance, and lighting across multiple variations and batch generations for large-scale projects.
Renders text in multiple languages with improved layout placement, ideal for branding across international markets.
## How to use
Go to the **ImagineArt AI Image Generator**.
From the model dropdown, choose **Seedream 4.0**.
Write your text prompt and upload up to **4 reference images** for detailed guidance.
Click **Generate** and wait for the model to process your image.
Go to the **ImagineArt Image Editor**.
Click **Settings** and choose **Seedream 4.0** from the model dropdown.
Upload your base image and apply edits or transformations.
Use **visual prompts** to add, replace, or remove elements and make precise adjustments to the composition.
## Prompting tips
* **Be specific** — Define subject, environment, and style in detail. Example: *"A vintage car parked on a sunny street with a dog, shot in a retro photography style."*
* **Use multiple references** — Upload images of your subject, background, and product together for consistent outputs.
* **Guide mood and style** — Add descriptors like *"cinematic lighting"*, *"flat lay"*, or *"ink illustration"* to shape composition.
* **Use 4K mode for final work** — Select **4K mode** for print-ready visuals or large-scale campaigns. Use 2K for drafts.
### Example prompts
> A red "Glaze Cherry" cosmetic bottle placed on top of two shiny fresh cherries, with a pink and white gradient background. Bold red text saying "New" is displayed on the bottle. The scene should reflect beauty product photography, glossy surfaces, and ultra-realistic lighting.
> A close-up portrait of a teenage boy with curly dark hair and freckles, wearing a navy tracksuit jacket, standing in front of a yellow wall. Looking intensely into the camera with a serious expression, in a candid street photography style with natural emotion.
> A Black person leans on a city overpass railing, gazing seriously at the camera. They wear a sharp white shirt with a tie and a skirt. The urban setting below features a road with passing cars, contrasting the subject's poised and editorial stance.
