ByteDance Launches Seedream 5.5 with 100-Round Image Editing

ByteDance has launched Seedream 5.5, the latest version of its AI image-generation model, on November 9, 2026. The new model introduces several improvements, including support for up to 100 rounds of image editing, native transparent image generation, and better text rendering.

Key Features of Seedream 5.5

Seedream 5.5 allows users to make up to 100 consecutive edits to an image while maintaining greater consistency. It also supports native RGBA output, allowing users to generate images with transparent backgrounds without requiring additional editing tools.

The update also improves text rendering, helping users create images with clearer and more accurate text.

Availability and Access

The model is currently available through ByteDance's Doubao app and Doubao Workspace. Jimeng AI and Volcano Ark are gradually providing trial access to users. The company also plans to introduce a Pro version in the future.

Image Quality and Performance

Early tests suggest that Seedream 5.5 can handle repeated image edits and indoor scenes with relatively stable results. However, the model still has some limitations, particularly when generating human anatomy and small objects such as glasses.

These issues show that some image-generation challenges remain despite improvements in editing capabilities.

API Pricing and Previous Versions

According to the report, editing a 2K square image through the API costs approximately 0.28 yuan (US$0.042) per image. This is less than half the reported cost of Seedream 5.0 Pro.

ByteDance has continued to improve the Seedream model series. Seedream 3.0 focused on image quality, prompt accuracy, and editing performance, while Seedream 4.0 introduced better controllability and additional tools.
