Seedream 4.5 builds on the foundation of version 4.0 with an emphasis on enhanced realism, precision editing, faster performance, and stronger semantic understanding. Released in early December 2025, it improves text rendering, multi-image consistency, portrait and fine detail fidelity, and spatial logic, while maintaining up to 4K output quality. Seedream 4.5 also offers more intuitive prompt interpretation and smoother editing workflows, making it especially well-suited for professional visual content creation, advertising, storyboards, product visuals, and creative production where higher accuracy and real-world detail matter.
