Модели ByteDance

Seedream 5.0 Lite is ByteDance’s multimodal image generation and editing model with stronger visual reasoning and instruction understanding than the previous generation. It can use reference images to preserve subjects and transfer style, create information-rich graphics, and combine text with visual composition. Kie provides separate text-to-image and image-to-image routes for this model.

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.

Seedream 4.0 is ByteDance’s advanced text-to-image and image editing model, designed for high-speed, high-resolution image generation and robust contextual understanding. It unifies generation and editing in a single architecture, supports complex visual tasks with natural-language instructions, and excels at multi-reference batches and diverse style transfers. Seedream 4.0 stands out for its ability to handle both content creation and modification, offering creative professionals and enterprises an all-in-one, efficient solution for imaginative and knowledge-driven visual tasks.

Seedream 5.0 Pro is ByteDance’s professional image generation and editing model. It improves prompt-to-image alignment, text rendering, structural coherence and visual aesthetics, and is designed for dense infographics, commercial design and precise changes to reference images. The Kie integration supports both text-to-image and image-to-image tasks.
