How to Use the Seedream 4.5 AI Model

1

Write Structured Prompts

Clearly specify the subject identity, shooting scope, lighting, material details, typesetting and layout intent. For high-quality commercial outputs, avoid vague descriptions, as Seedream 4.5 excels when prompts clearly define text positions, reference consistency and visual hierarchy.

2

Upload Reference Images

If you need stable facial features, product details, brand colors or composition consistency, upload one or more reference images. The model benefits from guidance from multiple reference images, especially for scenarios such as events, poster systems or repeated subject generation.

3

AI Processing and Target Image Generation

After image generation, check text clarity, identity retention and small design details before final export. If the result is close but not fully meeting requirements, you can regenerate it after adjusting typesetting, spacing, lighting or reference matching in the prompt.
