ByteDance Unveils Seedream 5.5, Image Model That Holds Up Over 100 Edits

At a glance

ByteDance has released Seedream 5.5, a new image generation model. It keeps images intact across many rounds of editing and improves transparent backgrounds and text rendering. The focus is on making it easier to use in design and content production.

Key points

1. 1

   ByteDance showed the same image edited 100 times in a row while unedited areas kept their colors and details.

2. 2

   The model can directly create transparent-background images, reducing the need to remove backgrounds by hand.

3. 3

   It renders complex and small text more accurately and adds more realistic skin, materials, and lighting.

4. 4

   In its own tests, the serious text error rate fell from 2.8% to 0.4%, but it trailed Nano Banana 2.1 at editing existing images.

Why it matters

Designers and content creators can use AI-generated images more directly in real work. Seedream 5.5 will roll out in stages to platforms such as Dreamina and Doubao.
