What is seedream 4.5?
seedream 4.5 helps you generate and edit images that stay consistent, readable, and ready to publish.

Practical use cases you can ship
seedream 4.5 is built for people who publish visuals on a schedule. Use it to create 10 ad variants from one campaign idea, keep a product photo consistent while trying new backgrounds, or draft poster layouts before final touch-ups. Creators also use seedream 4.5 to keep a recognizable look across a profileâsame character, same lighting mood, different scenesâso the feed feels cohesive. For small teams, itâs a fast way to turn one brief into a week of on-brand images without waiting on a full design cycle.

Edits that protect your subject
When you edit an image, losing identity kills trust. seedream 4.5 is designed to preserve key reference details (like facial features, lighting, and color tone) so your new versions still feel like the same person or product. This is useful for e-commerce (same SKU, new seasonal scene), social campaigns (same hero image, new copy/layout), and creator portraits (same identity, new style). The goal is simple: change what you wantâkeep what matters.

Poster-friendly layouts and clearer small text
Posters fail when the layout looks random or the small text becomes unreadable. seedream 4.5 highlights improvements for typography and dense text rendering, aimed at poster, logo, and brand-visual scenarios. In practice, that means fewer âalmost usableâ outputs and more drafts you can publish or polish quickly. If you work mobile-first, clearer headlines and price tags can directly help people understand the offer in one glance.
