Seedream 3.0

Seedream 3.0 is ByteDance’s third-generation text-to-image AI model, designed to produce high-resolution (2K), aesthetically refined images with improved layout, structure, and text rendering. It supports bilingual prompts (Chinese and English) and was trained on a significantly expanded and filtered dataset for better semantic coherence.

Technically, it introduced enhancements like mixed-resolution training, cross-modality RoPE, and resolution-aware timestep sampling. These innovations improved both image quality and generation speed — allowing 1K images to be generated in about 3 seconds.
