Seedream 4.5 Model Introduction

Model Overview

"Seedream 4.5" is a cutting-edge image generation and intelligent editing model developed by ByteDance's Seed Team. Designed to meet the strict needs of creators and designers, it has made remarkable progress in maintaining consistency of characters and objects and reproducibility of reference images. It supports native high-resolution output up to 4K (4096×4096), enabling professional-level creative production without compromise.

This model's greatest strengths include cinematic dramatic light and shadow expressions, detailed texture rendering, accurate and clear text insertion (text drawing) within images, and the ability to handle complex layout designs. As a result, it can beautifully complete tasks that were difficult for previous AI models, such as creating commercial posters and package designs with text, as well as consistent storytelling through multiple images.

It is compatible with a wide range of styles, from photorealistic portraits to product renderings and 3D graphics. Its partial high-precision image editing (inpainting) function is also excellent, making it a top-tier model that dramatically enhances the efficiency of all creative workflows in commercial settings, from character IP development to advertising and photo retouching.
