Seedream 5.5 questions

Not yet. As of October 2026, ByteDance lists Seedream 5.5 as launching soon on its Lumina platform, with no public API. Seedream 5.5 AI adds it as a model the day an API provider serves it. Until then you can create with Seedream 5.0 Pro, the model 5.5 builds on, plus 5.0 Lite and Flash.
Seedream 5.0 Pro for the best quality, posters with text and careful edits; Seedream 5.0 Lite when you need 4K; Seedream 5.0 Flash for fast, low-cost drafts. Your prompt and pictures stay when you switch.
Yes. A new account gets 20 credits — 4 Seedream 5.0 Pro images at 1K. Check in every day for one free Seedream 5.0 Flash 2K image, and a 7-day streak adds bonus credits (2 on day 3, 6 on day 7). After that, images use credits from one-time packs: 300 credits for $9.99. Failed images cost nothing.
From 2 credits on Seedream 5.0 Flash to 10 credits (Seedream 5.0 Pro, 2K) per image — 5 credits for Seedream 5.0 Pro at 1K, about $0.17 in the smallest pack. Reference images are included, and the button shows the exact cost before you generate.
According to ByteDance, 5.5 renders text far more accurately (4.53 vs 3.34 on its 15-language test), looks more realistic, keeps quality over many more editing rounds, and can output transparent images natively. Seedream 5.0 Pro already handles text, editing and up to 10 references well, which is why it's the default here.
Seedream 5.0 Pro, Seedream 5.0 Lite and Seedream 5.0 Flash, all for text to image and image editing. Seedream 5.5 will be added when it becomes available through an API.
Yes, it's one of Seedream's strengths. Put the exact words in quotes and say where they go, for example a headline "SUMMER SALE" at the top. Seedream 5.0 Pro is the most reliable for small or non-English text.
Yes. Upload up to 10 pictures (5 on Seedream 5.0 Pro). They're named Image 1, Image 2… in upload order; type @ in the prompt to insert one and say what it's for, for example "put the jacket from Image 2 on the woman in Image 1".
1K or 2K on Seedream 5.0 Pro and Flash, 2K or 4K on Seedream 5.0 Lite. Choose Auto to keep your first picture's shape, or a ratio from 21:9 to 9:16.
Native transparent output is one of the features ByteDance announced for Seedream 5.5; it isn't available here yet. Today's Seedream 5.0 models return a normal image with a background.
Yes, the images you make are yours to use, as long as your prompt and uploads don't infringe anyone's rights. See the terms for details.
