Seedream 4.5: Complete Guide to the Best Text-to-Image Model

Seedream 4.5 is a state-of-the-art text-to-image AI model known for its photorealistic output, accurate text rendering, and excellent prompt adherence. It's particularly strong at generating images that look like they were shot by a professional photographer — with natural lighting, realistic skin textures, and physically accurate environments.

While some models prioritize artistic or stylized output, Seedream 4.5's strength is making things look real. It's the go-to choice for product photography, portraits, architectural visualization, and any use case where realism matters.

Photorealistic generation: Produces images with natural lighting, accurate shadows, and realistic textures that rival actual photography.

High resolution: Supports up to 2K native output, and can be upscaled to 4K using the Image Upscaler.
