ByteDance Releases Seedream 5.5: Supports 100 Rounds of Continuous Editing and Native Transparent Asset Generation

November 9: According to ByteDance Seed's official blog, ByteDance has released the image creation model Seedream 5.5, which is being rolled out on platforms including Jimeng, Doubao and Volcano Ark. The model supports up to 100 rounds of continuous editing, with unedited areas remaining pixel-identical; it adds native RGBA transparent asset generation, eliminating the need for post-processing cutouts. Official evaluations show its severe text corruption rate has dropped to 0.4% and its minor text corruption rate to 1.7%; usability in film/TV and office scenarios is more than twice that of Seedream 5.0 Pro; and it outperforms GPT Image 2.5 Sunburst and Nano Banana 2.1 on both text structure and text-to-image realism.
