What Is Seedream 4.5?
Seedream 4.5 is the image model ByteDance's Seed team released in December 2025, also branded Doubao Seedream 4.5. Like the rest of the Seedream family, it turns a plain-text prompt into a finished picture and can edit a photo you upload — with a standout strength in rendering small, legible text inside images, plus strong character consistency across a series.
