Seedream 3

Seedream 3 is ByteDance's closed-source text-to-image model (Apr 2025). It generates native 2K resolution images without post-processing, with support for various aspect ratios. The model prioritizes fast generation and strong bilingual text rendering (Chinese and English) over the advanced editing and multi-reference features of later versions. It is well-suited for applications requiring quick turnarounds and clear text in both languages, such as social media graphics. Pricing starts from 4 CU.
