Seedream 4.5 is an image-generation foundation model developed by ByteDance Seed, optimized for high-resolution fidelity, consistent batch outputs, and production pipeline integration. It follows complex prompts well, improves in-image text rendering, and builds on prior Seedream iterations that added bilingual prompt understanding and RLHF-based alignment to better match human preferences. Seedream 4.5 is positioned for creators, designers, marketers, and production teams requiring brand-safe, repeatable assets and can be deployed via platform endpoints or integrated into automated pipelines.
