Seedream-4.0 Now Available
Seedream is a state-of-the-art (SOTA) multimodal image creation model based on a cutting-edge architecture. It breaks the creative boundaries of traditional text-to-image models by natively supporting text, single-image, and multi-image inputs. Users can freely combine text and images to enable diverse creative approaches within the same model, including multi-image fusion creation with subject consistency, image editing, and batch image generation. This makes image creation more free and controllable.
Charges are based on the actual number of images generated; no fees will be incurred for failed generation.
