Made With Seedream 4.5
A spread of prompts run through Seedream 4.5 — photorealistic portraits, 4K landscapes, product shots, bilingual posters, fashion, and food.
Why Seedream 4.5
Seedream 4.5 is ByteDance's latest image model — an upgrade over Seedream 4.0 with stronger prompt adherence, higher aesthetic coherence, native 4K output, and the reliable in-image text that most diffusion models still struggle with.
Photorealistic Output
Seedream 4.5 renders convincing textures, skin tones, and lighting. Portraits, product shots, and lifestyle scenes hold fine detail and cinematic light without the over-smoothed, plastic look common in diffusion models.
Native 4K Resolution
Output natively up to 4096 px so you can drop images straight into print, large-format advertising, and high-DPI screens — no separate upscaling pass and none of the softness it introduces.
Bilingual Text Rendering
One of the strongest models available for text inside images: Seedream 4.5 renders accurate, readable English and Chinese in posters, labels, and infographics, so branded copy lands right without a separate design step.
Reference-Image Consistency
Supply up to 14 reference images to lock a subject's identity, a style, or a product across a whole batch. Seedream 4.5 keeps coherence over multiple outputs without the per-image drift that breaks e-commerce and character sets.
Text-to-Image and Editing in One Model
Start from a written prompt or bring in your own image — Seedream 4.5 handles both. Its reference workflow lets you restyle, extend, or refine a shot while the core subject stays recognizable.
Runs Free in Your Browser
No download, no GPU, no setup. Seedream 4.5 generates in the cloud and streams results back to the browser, and your free credit balance is enough to test real prompts before committing to a plan.
Best Use Cases for Seedream 4.5
Where Seedream 4.5's photorealism, native 4K output, bilingual text rendering, and reference consistency turn into finished work.
Posters, ads, and social creatives with readable English or Chinese headline text baked directly into the image — skip the separate design pass and iterate on the message in the prompt.
Studio product shots and lifestyle mockups at 4K, with up to 14 reference images keeping a product consistent across angles, backdrops, and scenes so a listing looks like one shoot.
Cinematic light, accurate skin tones, and crisp fabric detail make Seedream 4.5's photorealism a strong stand-in for a portrait or fashion editorial shoot.
Native 4K means no upscaling penalty for billboards, posters, or print. Generate once and use the file at full size with detail intact.
Produce the same creative in English and Chinese with the text rendered cleanly in-frame — handy for cross-market campaigns, packaging, and signage that need to read correctly in both languages.
Anchor a character or style across a series with reference images, then explore variations while identity holds — useful for storyboards, game concepts, and mood boards that must stay on-model.
