Reference-guided image generation for polished high-resolution stills.

Choose Seedream 4.5 when a single output or variation needs stronger finish than a rough draft. It accepts prompt and reference images, supports 2K, 4K, or custom sizes, and can match the input aspect ratio, making it a direct choice for high-resolution still work.

Compared with Seedream 4 or Seedream 5 Lite, this description should be read as a single-image and reference-variation choice, not a sequencing choice. Fine text, exact logos, and strict continuity still need review.
