According to 36Kr, ByteDance released Seedream 5.5, its latest image-generation model, on November 9. The update supports up to 100 editing rounds, native transparent image output in RGBA format, and improved text rendering. The model is available in Doubao and Doubao Workspace, with trial access opening gradually for Jimeng AI and Volcano Ark.
API editing costs approximately 0.28 yuan (US$0.042) per 2K square image, less than half the price of Seedream 5.0 Pro. Testing showed stable performance on repeated edits and indoor scenes, though the model still produces errors in human anatomy and small objects.
