Seedream 4.0｜One Photo Works
Upload one or two photos, or just type a sentence — get hyper-real portraits, posters and one-line edits. Chinese prompts welcome, 4K export.
Seedream 4.0 image generator: one line or one photo becomes a hyper-real portrait, poster or edit. Accurate text, 4K export, free to try now.
Features
- One-Line Generation——No photo needed. One sentence of plain description and the person, scene and lighting render in one pass — beginners just copy a template.
- Reference-Based Edits——Upload the photo to fix, say what changes in one sentence — swap the backdrop, erase strangers, change outfits. Only what you named moves.
- Native Chinese Prompts——Chinese understanding is the home advantage. No English spellbooks to memorize — the more detailed your plain words, the better the render.
- Face-Locked Portraits——One selfie turns into Korean portraits and ID photos. Face shape and features stay locked on you — no generic influencer face.
- Flawless Poster Text——Bottle English and poster headlines spelled right the first time — no cracks, no gibberish. Sellers can ship it directly.
- 4K HD Export——Hair, rain and neon survive the zoom. Ultra HD frames stay clean enough for prints and display.

FAQ
- Is this the original Seedream 4.0?
- Honestly: not the original 4.0 weights. This page is powered by the newer Seedream 5.0, the successor in the same family — text-to-image, precise editing and multi-image fusion are a superset of 4.0, so results are only stronger. Prompts written for 4.0 tutorials work here unchanged. We will switch to true 4.x weights the moment they are onboarded.
- Can one selfie become a studio portrait?
- Yes — that is its most popular use. Upload a front-facing, evenly lit selfie with nothing covering your face, pick photorealistic style plus portrait ratio plus ultra HD, and describe the backdrop and outfit. Generate 4–6 at once and keep the most identical one. Side profiles, steep angles and heavy filters break faces — use the untouched original.
- How do I avoid fake faces and broken hands?
- Three tricks: use photographic realism words (85mm portrait, natural pores, catchlights) instead of flawless-CG words; draw at most one hand and keep it simple — hands in pockets, holding coffee, chin resting; make the face at least a third of the frame, then repaint the face region for a second pass.
- Seedream 4.0 vs Midjourney for real people?
- For the most photographic real person, pick the Seedream family: Asian features, skin texture and catchlights look most natural, Chinese prompts just work, and 2K output is ready for portraits and product shots. Pick Midjourney for atmospheric movie-poster looks. Pick FLUX if you need a local studio pipeline with fine control. For fast client work, portraits and ID photos, this family is the least hassle.
- Can I use the images commercially?
- Personal projects, social posts, avatars and wallpapers — play freely. For commercial use (paid ads, packaging), check Loomi's subscription license terms and the official terms before you commit. You can always draft samples first and upgrade when the job is confirmed.
- How fast is it, and is it free?
- Results land shortly after you hit generate (the official page cites about 1.8s for a 2K image; your mileage varies). Sign in and try free — quotas and plan prices follow the on-site notices, no card traps.
- Do Seedream 4.0 tutorials still work here?
- Yes. This page runs on Seedream 5.0, the successor to 4.0, with fully compatible prompt syntax — portrait templates and editing one-liners from 4.0 tutorials paste straight in and render even better.
