ByteDance has officially released its Doubao image creation model, Seedream 5.5. Compared with the previous generation, Seedream 5.0 Pro, the new model delivers significantly faster generation speed, improved stability in multi-turn editing, native support for transparent material generation, and targeted optimization of image realism and small-text rendering—making it better suited to the quality, stability, and efficiency demands of professional creation scenarios. The model is now available across Doubao, Doubao Work, and Jimeng, with API access coming soon to Volcano Ark. Billing continues under the two-stage structure of "input image + output image," with no charges for text tokens. For 2K square image editing, for example, the cost is approximately 0.28 yuan per image—less than half that of Seedream 5.0 Pro. A Pro version of the Seedream 5.5 series will follow, supporting more complex context input and creation instructions to enhance performance on professional tasks. The team will also expand the model's application in Agent workflows to meet the real production needs of fields such as film and television, e-commerce, advertising, and design, while exploring broader general visual intelligence.
