What Is the Seedream Image Generator?
Seedream is ByteDance Seed's image model family — and this page puts every version of it behind one prompt box: Seedream 5 Lite for fast 2K drafts, Seedream 5 Pro for premium campaign work, and the brand-new Seedream 5.5with 100-round continuous editing and native RGBA transparency. No ByteDance account, no API key, no code — type a prompt, get the image.
Two ways to work: generate right on this page for one-off images, or open the AI Infinite Canvas when a job needs multi-step workflows, layering, and agent assistance. And when Seedream isn't the right tool for the shot, the canvas switches you into 30+ other top models — GPT-Image-2.6, Nano Banana Pro, Midjourney — without leaving.
New Seedream versions land on this page as they release. Bookmark it; it's the fastest way to try each generation of the model family.

Which Seedream Model Should You Use?
- 5 Lite — you're exploring compositions or generating volume. Cheapest, fastest, good enough for drafts.
- 5 Pro — the image is the deliverable. Campaign visuals, poster layouts, multilingual typography — Pro is the family's precision instrument.
- 5.5 — the job is an edit chain or needs transparent files: product shots that survive 20 revision rounds, stickers and cutouts straight to RGBA, photoreal work where lighting and skin texture carry the image.
Rule of thumb: draft on Lite, ship on Pro, iterate on 5.5.
What You Can Do — Two Workflows
Text to Image — Campaign-Grade in One Prompt
The featured example (prefilled in Template 1) is a luxury fashion campaign:
"Luxury fashion campaign. Main subject: young male model wearing a mustard oversized sweatshirt, one foot resting on a low cube. Editorial studio lighting, bold 'GO HIGHER' typography, premium magazine photography."
Structure is what makes it work — subject, pose, lighting, typography, style, each in its own slot. Keep the skeleton, swap the nouns: your product, your word, your palette.
Image to Image — Edit Chains That Don't Decay
Upload an image on 5.5 and edit in rounds: swap the backdrop, then the outfit, then the lighting — unedited regions hold at the pixel level, so round twenty looks as clean as round one. This is the workflow that used to break image models; it's now Seedream 5.5's signature.
How to Use the Seedream Image Generator
- Pick a template — text-to-image on 5 Lite, or T2I/I2I on 5 Pro.
- Write your prompt — any language; structured prompts (subject → setting → camera → light → style → ratio) get the best mileage.
- Generate — results render on the page in seconds; keep the tab open.
- Level up when ready — open the result in the AI Infinite Canvas for multi-step workflows, or switch the same prompt to GPT-Image-2.6, Nano Banana Pro, or Midjourney and compare outputs side by side.
Why Generate Seedream Images on Oimi

- Every top model in the same place — Seedream beside GPT-Image-2.6, Nano Banana Pro, Midjourney, and 30+ more; A/B the same prompt across families and keep the winner. One credit balance covers all of them.
- Free credits to start — test each Seedream version before paying; failed tasks auto-refund.
- Privacy-first — uploads are used only for your generation and auto-delete after about a week.
Seedream Prompt Tips
Do:
- Structure beats length: subject → pose → setting → camera → lighting → typography → style → ratio, each in its own clause
- Put exact text in quotes for typography (
bold 'GO HIGHER' typography) — you get the spelling you specify - On 5.5, ask for transparency explicitly:
isolated on a fully transparent background, RGBA, clean edges— native alpha means it arrives usable - For edit chains, change one thing per round on 5.5 — that's how the pixel-level preservation shines
Avoid:
- Wall-of-adjectives prompts — the structured example above outperforms a paragraph of vibes on every Seedream version
- Mixing "no text" with typography requests — pick one
- Editing the same image across different model versions mid-chain — consistency locks belong to one model per chain
FAQ
What is Seedream?
ByteDance Seed's image generation and editing model family. This page runs Seedream 5 Lite, 5 Pro, and the new 5.5 — text-to-image, image-to-image editing, and native RGBA — behind a single prompt box.
What's new in Seedream 5.5?
Three things: 100 rounds of continuous editing with pixel-level preservation of unedited regions, native RGBA transparent/semi-transparent output with layered export, and a photorealistic rendering upgrade. Full breakdown in our Seedream 5.5 deep dive.
Seedream 5 Lite vs. Pro — which should I use?
Lite for drafts and volume (fastest, 2K); Pro for deliverables (campaigns, posters, typography). Same canvas, one click to switch — draft on Lite, re-run the winner on Pro.
Is the Seedream image generator free?
New Oimi accounts get free credits, so your first generations cost nothing. Failed tasks refund automatically; one balance works across every model on the platform.
Do I need the BytePlus API to use Seedream?
No. Oimi hosts the models — you write prompts here, no API key, no developer setup. If you do want API-style control, the Infinite Canvas exposes the full workflow parameters.
Seedream vs. GPT-Image-2.6 vs. Nano Banana Pro — which should I use?
Seedream 5.5 for long edit chains and transparent layered assets; GPT-Image-2.6 for GIFs and emotes; Nano Banana Pro for 4K print and elite typography. All three run on Oimi — same prompt, side-by-side comparison, one credit balance.
Can Seedream generate transparent backgrounds?
Seedream 5.5 can — natively, with an alpha channel and clean edges, including semi-transparent materials. Earlier versions approximate transparency from prompt text and need an edge-cleanup pass.
Can I use generated images commercially?
In general, yes — for personal and commercial purposes, provided you hold the rights to any input materials and follow the platform's content policy.
Will new Seedream versions appear here?
Yes — this page is the family home. Each new Seedream release lands here as a selectable model, usually within days of ByteDance's announcement.
