Upload 14 References. Keep Every Identity Intact.

Most models blend everything together. Seedream 4.5 keeps each reference distinct. Upload your model, your product, and your background — the model maps what to preserve from each source and generates without losing any of them.

Face & Subject Preservation

Upload a portrait or product shot and Seedream 4.5 locks in the exact features — bone structure, skin tone, proportions. Your character or product looks identical across different scenes, angles, and lighting conditions.

Lighting & Color Tone Match

Reference a brand mood board or existing product photo and the model matches the light direction, shadows, and color palette in every output. Your campaign images are cohesive because the lighting actually matches — not by chance.

Up to 14 Reference Images

Need to combine a character, an outfit, a product, and a background? Upload all of them. Seedream 4.5 accurately identifies what belongs to each source and preserves it separately — no blurred identities, no merged features.

Native 4K Output

Every image renders at full native 4K resolution. No upscaling, no hallucinated textures added after the fact. Poster-ready, e-commerce-ready, print-ready from the first generation.

Typography That Doesn't Need Photoshop

Seedream 4.5 renders correctly spelled, legible text directly in the image — headlines, captions, mixed languages, small print. Generate a complete poster and download it straight to production.

Correctly Spelled Text, Every Time

Headlines, body copy, taglines — Seedream 4.5 generates text that is spelled correctly and reads clearly. No garbled letters, no nonsense characters, no post-generation corrections in Photoshop.

Small Print Stays Readable

Fine print, captions, and secondary copy remain legible even at small sizes. Generate a fully layered poster — all text tiers intact — without losing the details that matter.

Mixed-Language Support

Working with English and Chinese in the same layout? Seedream 4.5 handles mixed-language typography without breaking either script — a capability where most competitors fall apart.

Structured Commercial Layouts

Text placement, visual hierarchy, and balance are handled with commercial-grade structure. Your output looks like a brief was written and a layout was designed — because, in a sense, it was.

For Creators Where Precision Is the Job

Seedream 4.5 is for professionals who need reference consistency, readable text, and 4K quality — where "close enough" isn't an option.

E-Commerce Sellers

Generate consistent lifestyle shots from one product photo. Your product's texture, color, and material stay accurate across every background swap — no reshoots, no retouching, at scale.

Marketing & Brand Teams

Brief your AI like a designer — reference images in, campaign-ready assets out. Every poster, KV, and social card shares the same visual language.

Graphic Designers

Prototype complete layouts with typography already baked in. Seedream 4.5 outputs first drafts that are 80% production-ready — fewer revisions, faster handoffs.

Content Creators & Influencers

Your character or visual identity keeps its integrity across every post. No drift, no jarring style changes — just a consistent presence your audience recognizes.

Filmmakers & Storyboard Artists

Characters look the same from panel to panel across your entire storyboard. Build visual narratives without losing character identity between scenes.

Photographers & Retouchers

Replace backgrounds, swap objects, or change lighting with text instructions. Seedream 4.5's inpainting makes targeted edits while preserving everything you want to keep.

I've been testing Seedream 4.5 in Leonardo and the results are crazy. The model handles cinematic lighting, realism and scene detail extremely well. Created 10 cinematic shots across different genres.

Seedream 4.5 is so good with Style Transfer.

Seedream text-to-image is absolutely excellent. It's way ahead of Flux, probably the best model for people right now — extremely high prompt coherence.
