Z-Image-Base

Z-Image Base (zimagebase.com) serves as the official platform for Alibaba’s Tongyi Lab and its high-performance family of open-source diffusion models. Built on a sophisticated 6-billion parameter "Scalable Single-Stream DiT" (S3-DiT) architecture, the model treats text and visual data as a unified stream to achieve state-of-the-art efficiency. This technical foundation allows the platform to deliver photorealistic, cinematic-quality results that rival leading proprietary tools like Midjourney, while maintaining a footprint small enough to run on consumer-grade hardware with as little as 16GB of VRAM.

The platform provides access to three specialized model variants: Z-Image-Base, the core non-distilled foundation ideal for fine-tuning; Z-Image-Turbo, a speed-optimized version capable of sub-second inference; and Z-Image-Edit, which handles instruction-based image transformations. A standout feature across the suite is its superior bilingual text rendering, which accurately generates complex typography in both English and Chinese. Unlike many commercial alternatives, Z-Image is designed for high prompt adherence and "relatively uncensored" output, making it a flexible choice for diverse creative workflows.

On the website, users can interact with live demos to test the model’s reasoning and prompt-enhancement capabilities directly in their browser.
