Seedream 5.0 Pro is BytePlus's reasoning-first image model for generating and editing images from a text prompt. It renders clear, correctly spelled in-image text, including multi-line layouts and non-Latin scripts (e.g. Chinese and Japanese), and uses multi-step visual reasoning for coherent, physically plausible scenes. Pass up to 10 reference images to lock character identity, keep product series consistent, or edit an existing shot. Output up to 3136px, prompts up to 3,500 characters. Ideal for posters, packaging, UI mockups, storyboards, and marketing key art.
