Seedream 4.0 T2I

Seedream 4.0 is ByteDance Seed team's unified text to image model that converts natural language prompts into high fidelity images. It uses a unified architecture that also supports image editing, enabling consistent rendering across generation and modification tasks. The model can process multiple reference images to retain stylistic or identity cues across a batch, and it handles high resolutions up to 4K with flexible aspect ratios, improved rendering of typography, scene layout, and lighting. According to its technical paper, Seedream 4.0 unifies text to image, editing, and multi image composition in a single framework. In practice it produces crisp 2K images in under 1.8 seconds and scores well on prompt following, aesthetics, and in image text rendering across a broad range of creative workflows.
