Z-Image Base's Core Features
Non‑Distilled Foundation Model (6B)
Built on a powerful 6‑billion parameter non‑distilled foundation model (Tongyi‑MAI) for higher fidelity, richer semantics and more reliable generation compared with distilled alternatives.
Reference Image Guidance with Strength Control
Optionally upload a reference image to steer composition, style or subject; a strength parameter controls how closely the output follows the reference.
Built‑in Prompt Enhancer
Automatic prompt enhancement injects logic, detail and common‑sense reasoning to boost result quality from even simple user prompts.
Custom High‑Resolution Outputs
Generate images at custom sizes (site supports high resolutions up to 1536×1536) and any aspect ratio needed for social, web or print.
Photorealism & Bilingual Text Rendering
State‑of‑the‑art photorealistic rendering with accurate bilingual (Chinese/English) typography and fine detail handling for posters and typographic designs.
