Seedream 4.5 T2I

Seedream 4.5 text to image is ByteDance's transformer based generative model, built to create detailed and coherent images directly from written prompts. It uses a large scale vision transformer paired with a language encoder that maps text descriptions into rich visual features, which produces strong spatial consistency, accurate object relationships, and stable detail across different styles. The 4.5 release sharpens prompt adherence and native text rendering at resolutions up to 2048 by 2048, with designer level typography that holds up even at small font sizes that most competing models struggle to produce. Seedream 4.5 T2I accepts up to ten reference images, can output up to six matching variants at once, and handles both English and Chinese text cleanly.
