## The update

The ByteDance Seed team has officially launched Seedream 5.5, a next-generation image creation model now available on platforms including Jimeng, Doubao, Doubao Work, and Volcano Ark. This update focuses on three core improvements. In terms of editing precision, the model maintains pixel-level integrity in non-edited areas during multi-round edits, allowing users to make up to 100 consecutive modifications to a single work without damaging original details. Functionally, it adds native RGBA transparent asset generation, enabling users to directly use generated content for design composition without manual background removal, thus streamlining workflows. Furthermore, the model delivers more realistic image textures and optimizes text rendering, reducing severe text distortion rates to 0.4%, which significantly enhances the usability and authenticity of the generated content.
