The site has 19 and 3 reproducible cases for each, respectively. Below, we compare strengths, prompt writing, and final results side by side.

The Bottom Line

Seedream 4.5 is better for In-image text and headline layout; Z-Image Turbo is better for Bilingual Chinese-English text rendering. Running the same idea through both is usually worth it — they "listen" differently, so the prompt has to be adjusted to match.

With so few sampling steps, specificity pays. Put the frame and the subject's position at the very front and the style description after, or it will treat the style as the subject.
