ByteDance: Doubao-Seedream-4.5 API

Seedream 4.0 is a state-of-the-art (SOTA) multimodal image creation model based on a leading architecture. Its generated aesthetics, instruction compliance, structural integrity, and subject consistency are among the world's best. The model uses a unified architecture to unify text-to-image and editing capabilities, natively supporting text, single-image, and multi-image input. Through deep reasoning based on prompts, it automatically adapts to the optimal image aspect ratio and generation quantity, and can continuously output up to 15 content-related images at once, supporting 4K ultra-high-definition output.
