Seedream 5.5 is the image model ByteDance's Seed team released on November 9, 2026. It promises that the same image can be edited over many rounds without drifting, native transparent assets, clearer small Chinese and English text, and more realistic portrait texture. Users in China should first look for the model entry inside Jimeng and Doubao; the API is not open yet, so anyone planning to call it should not rush.
Where to look first — China and overseas separately
- The entry points in China are Jimeng, Doubao, and Volcano Ark: open the app and look for the Seedream 5.5 model option inside the image generation feature.
- Overseas it will land on Dreamina, CapCut, and BytePlus; if you are abroad, check those three first to see whether it is available.
- The same image can be edited over many rounds without redrawing it from scratch each time, which suits refining one image again and again.
- When you need transparent assets, generate natively transparent images directly instead of cutting them out afterward, saving one step.
What you can do now, and what you cannot
What you can do is generate and edit images directly in Jimeng and Doubao, trying first the scenes that used to go wrong easily — small text, posters, and portraits. Edit one place at a time rather than piling on many requirements at once, and check the result after each round before moving on to the next. What you cannot do is call the API: as of November 10, BytePlus ModelArk has not published an API model ID, a price, or a launch date for 5.5, and third-party aggregators return "not found" when querying this model. Any channel claiming it can call the 5.5 API should be verified first.
If you need images urgently, you don't have to wait idly: use Seedream 5.0 Pro for now — its BytePlus ModelArk model ID is dola-seedream-5-0-pro-260628. You can also switch to GPT Image 2.6 or Nano Banana 2.1, and move to 5.5 once its API officially opens. When waiting for API news, trust only official announcements — don't believe prices or launch dates from dubious sources.
