Bytedance launches Seedream 5.5 with pixel‑stable 100‑round editing and native RGBA output
Bytedance announced Seedream 5.5, an image-generation model it says preserves unchanged areas at the pixel level across up to 100 iterative edits without color drift, produces native RGBA images with transparent backgrounds, and improves rendering of light, materials, skin textures and dense small text. The company says the model outperforms competitors in text structure and realism and is rolling out gradually via Jimeng, Doubao, Doubao Work and Volcengine Ark, with a Pro version planned.
