Seedream 4.5

Seedream 4.5 is ByteDance's closed-source image editing model (Dec 2025). It modifies images via natural language prompts like "remove background" while preserving facial features and lighting. Accepting up to 10 reference images for multi-image editing with strict consistency, it prioritizes accurate instruction following and feature retention over speed. This makes it effective for product iteration, character design refinement, and style transformation workflows. Generation takes ~6 seconds, with pricing from 6 CU. For similar editing capabilities, consider Nano Banana Pro.
