ByteDance has released Seedream 5.5, an image-generation model that supports as many as 100 consecutive edits while preserving unmodified areas at the pixel level during iterative image changes.

The model is rolling out on platforms including 即梦, 豆包 and 火山方舟. It can also generate transparent assets in RGBA format without a separate background-removal step.

ByteDance’s evaluations put the severe text corruption rate at 0.4% and the minor rate at 1.7%. They also found usability rates in film and office settings were more than twice those of Seedream 5.0 Pro.

In comparisons with GPT Image 2.5 Sunburst and Nano Banana 2.1, ByteDance’s evaluations rated Seedream 5.5 higher for text structure and text-to-image realism.
