About Seedream 5.0 Pro
ByteDance Seedream 5.0 Pro is an image generation and editing model built for precise, region-level control and professional design work. It generates images from a text prompt and performs single-image and multi-reference editing (recolor, material swap, object replacement, multi-image fusion), with native multilingual text rendering across more than 10 languages and strong layout reasoning for text-dense compositions.
Each request returns a single image at up to 2K (2048x2048) across a range of aspect ratios, and up to 10 reference images can guide an edit.
