Z-Image-Turbo_clear (distilled)
Z-Image-Turbo_clear (distilled) tends to generate very similar-looking images with little diversity.
Model Format and Quality
Generally, model size and image quality are proportional.
FP32 > FP16 ≒ BF16 > MXFP8 > FP8_svd_scaled > FP8
Generation time varies greatly depending on whether the model can be loaded into VRAM, and the supported formats are determined by the GPU generation.
MXFP8 is the latest standard designed for the RTX 5000 series. On unsupported GPUs, however, fallback mechanisms will actually slow down processing, so their use is not highly recommended.
For a comparison of image quality and generation time by format, please see this page.
If you are unsure which precision to use, it is safest to choose the BF16 format.
VAE
For the Z-Image_clear_photoreal model, we recommend using Z-Image_clear_vae.
Z-Image_natural_vae: lower saturation, more natural look
Z-Image_clear_vae: higher saturation, vivid and vibrant look
We provide several color-style variations, so feel free to choose the one that matches your preference.
