Image Model
Seedream 5.0 Flash is BytePlus's speed tier of the Seedream 5.0 family — text-to-image and image editing at lower cost and latency than Pro.
It composes up to 10 reference images into one output and renders in-image text natively across 15 languages.
Pick it over Pro when speed and cost matter more than the last bit of image quality; its outputs also feed directly into Seedance for video.

Key Features
Generation
- Multi-Reference Composition: Blends subjects, styles and materials from up to 10 reference images into one output
- Multilingual Text: Renders in-image text natively across 15 languages
Editing
- Interactive Editing [TBD]: Point at a region — via coordinates or a freeform sketch — and describe the change; the model edits only that area and blends it into the scene

Prompting Tips
- Describe the aspect ratio or purpose in the prompt rather than hand-setting pixels
- Name the materials and layout to preserve when blending multiple references — wood grain, leather, glass
- Prompt in one of the 15 native languages for the most reliable in-image text
- Generate with Seedream, then pass the result into Seedance for video
