Why it matters

Designers and marketers who iterate on product shots, stickers or ad creatives need edits that don't disturb the rest of the image and assets they can layer. Seedream 5.5 targets both.

Highlights

Multi-turn editing that ByteDance says keeps unedited regions intact at the pixel level across successive changes.
Native transparent and semi-transparent backgrounds, including separate RGBA layers and sticker sets in one step.
More natural lighting, materials and skin textures, per ByteDance's examples.
Can be tried in Dola and the BytePlus ModelArk playground.

Taken from the project's own README, docs or launch page. Claims about speed or accuracy are the maker's unless stated otherwise.

Try it if: You make product images or stickers and want to edit them step by step or export with transparent backgrounds.
