Choose seedream 4.5 when an image job depends on several references, preserved product details, controlled scene changes, or output up to 4K. The supplied evidence shows broad scenario coverage rather than comparative quality, so it is a practical candidate for structured editing workflows but not a basis for assuming perfect text, anatomy, counting, or identity consistency.

Сильные стороны

Multi-reference capacity
Support for up to 8 reference images gives creators room to combine object, identity, garment, and scene guidance in one workflow.
High-resolution output
The model supports output up to 4K for assets that need more detail or room for downstream layout work.
Commercial image coverage
Published selections cover product lighting, advertising composition, product preservation, scene relighting, and cross-ratio outpainting.
Text and layout workflows
The evaluation suite includes multilingual typography, structured UI graphics, and in-image text replacement, making it relevant to design-led prompts that mix imagery and copy.

Ограничения

No quality guarantee
The supplied selections document completed runs, not comparative wins or guaranteed prompt accuracy. Critical object details, anatomy, counts, and text still need review.
Reference clarity matters
Up to 8 references gives the model more source material, but crowded or conflicting inputs can make it harder to determine which attributes should be preserved.
Proofread generated text
Typography and text replacement were included in the evaluation suite, but the evidence does not establish error-free spelling across languages.
Complex edits can take longer
The longest published selection in the supplied suite took 52.5s, so reference-heavy edits may require more waiting than simpler generations in this set.

Когда стоит выбрать другую модель
