What is Seedream 5.0 Pro?

Seedream 5.0 Pro is ByteDance's multimodal image model for controlled generation, precision editing and complex information visualization, such as infographics, diagrams and posters.

It also produces realistic portraits and renders text in multiple languages. On Flashloop it takes a text prompt or up to 10 reference images and outputs at 1K in Basic quality or 2K in High quality.

The model is aimed at work where the layout has to be right: labeled diagrams, posters with several blocks of copy, menus and packaging. Prompts can run to about 5,000 characters, which leaves room to specify every element, its wording and its position. References let you steer identity, style or composition instead of describing them.

Seedream is ByteDance's image line and is separate from Seedance, its video models. Pick Seedream 5.0 Pro for text-heavy and information-heavy images and for precise edits. Seedream 5.0 Lite is cheaper and faster and goes up to 3K. Nano Banana Pro is worth comparing for plain-English photo edits.
