Generate Images with Seedream — 3.0 to 5.0
ByteDance's Seedream family in one dropdown: fast native-2K drafts on 3.0, unified generation and editing on 4.0, and 4K flagship quality on 4.5 and 5.0.
Seedream is ByteDance's text-to-image model family, best known for rendering legible text inside images — posters, packaging, UI mockups — in both English and Chinese. PixGenN carries the full current lineup: Seedream 3.0 for ~3-second native-2K drafts, 4.0 for unified generation plus editing from 1K to 4K, 4.5 for enhanced 4K fidelity with the best text rendering, and 5.0 with chain-of-thought reasoning and web search.
Every version costs 4–5 credits per image and runs in the same generator as PixGenN's other image models, so switching versions — or jumping to Nano Banana for a different look — is a dropdown, not a new subscription. Generated images feed straight into image-to-video when you want them to move.
How it works
- Step 1
Pick a Seedream version
3.0 for speed, 4.0 for generation + editing, 4.5 for 4K fidelity and text, 5.0 for reasoning and web-aware prompts.
- Step 2
Write the prompt
Describe subject, style, and any text the image should carry — text rendering is Seedream's specialty.
- Step 3
Generate and iterate
Images render in seconds at 4–5 credits each. Iterate on the prompt, then download the keeper.

How good is Seedream at text in images?
It's the model family's signature strength: legible, correctly spelled text in both English and Chinese, which makes it the go-to for posters, packaging, and UI mockups.
Is Seedream free to try?
Yes — PixGenN's free tier includes starter credits with no credit card, enough for a set of Seedream generations before you pick a plan.
Seedream or Nano Banana — which should I use?
