High Detail

# Z-Image-Turbo — Higher Detail on iPhone, iPad, and Mac

Z-Image-Turbo trades a bigger download for noticeably higher detail. It runs on a 12 GB iPhone, an 8 GB iPad, or any Apple Silicon Mac — on an 8 GB iPad it works but takes its time. It supports negative prompts and on-device prompt rewriting, and its upscaler reaches 4x on capable hardware.
