Seedream 5.5 Guide

Seedream 5.5 is ByteDance’s newest image generation and editing model, released by its Seed team on November 9, 2026. Its headline features are stable editing over many rounds and native transparent backgrounds.

Edit the same image again and again without it slowly falling apart.

ByteDance says Seedream 5.5 can edit one image up to 100 times in a row, keeping unedited areas identical down to the pixel, without the colour drift that often builds up in repeated AI edits.

It can generate native RGBA images with transparent backgrounds, so stickers, product cut-outs, icons, and design elements drop straight into layouts without a separate background-removal step.

• Better rendering of dense, small text
• More realistic skin and lighting
• ByteDance reports severe text errors in 0.4% of its test images

In ByteDance’s own tests, Seedream 5.5 beat Seedream 5.0 Pro and claimed an edge over OpenAI’s GPT Image 2.5 and Google’s Nano Banana 2.1 on text and realism. These results have not been independently verified.
