What Is Z-Image Base?
Z-Image Base is the full foundation model behind the faster Turbo edition. It trades speed for richer variation, stronger negative-prompt control and a wider search space across people, products, layouts and visual styles.

Z-Image Base Test Results
Testing in progress
Every model runs the same eight-category prompt set — portrait, product, poster text, anime character, interior, multi-reference, image editing and character consistency — recording generation time, success rate, text accuracy and identity retention. That run has not finished for Z-Image Base, so this page shows no scores. We do not publish numbers we have not measured.
Z-Image Base Limitations
- Slower than Z-Image Turbo
