Seedream 4.5 is the newest proprietary image generation model from ByteDance. Compared to Seedream 4.0, it offers substantial overall improvements—particularly in editing consistency, where it better maintains subject details, lighting, and color tones. The model also delivers enhanced portrait clarity and improved small-text rendering. Its ability to compose multiple images has been significantly upgraded, and advances in both inference performance and visual aesthetics allow for more accurate and artistically expressive image creation.
