Overview

Seedream 4.0 Edit specializes in reference-based image editing, where you provide a source image and describe the transformation you want applied. The model uses the reference image as a structural and visual guide, producing edits that maintain the core identity of the original while applying your requested changes.

The model offers fine-grained control over output dimensions through predefined size presets ranging from square to portrait and landscape orientations. It supports both 1K and 2K output resolution, and can generate up to 2 variations per request for comparison.

Seedream 4.0 Edit is particularly effective for product photography refinement, character restyling, and scene adaptation. Its reference-based approach ensures edits feel grounded and natural rather than arbitrary, making it a reliable tool for professional image editing workflows.
