Seedream 5.0 Pro

Try Seedream 5.0 Pro in the Workbench

Run this model interactively, tune parameters, and compare outputs.

Model ID: bytedance-seedream-5-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. Pick an aspect ratio and a 1K or 2K resolution level to set the output dimensions. Each request returns a single image up to 2K (2048x2048), and up to 10 reference images can guide an edit.

Example request

Use the Workbench as a request builder: configure parameters for this model in the UI, then open the API tab to copy the exact cURL or Python call.
