Z-Image is an AI image generation startup built around a highly efficient 6-billion-parameter diffusion transformer designed for real-world creative workflows. The platform focuses on delivering photography-level realism, fine-grained control over lighting and texture, and clean composition while keeping the model compact and practical to deploy. By requiring only 8 inference steps and supporting sub-second latency on enterprise-grade GPUs, Z-Image enables responsive interactive experiences for both end users and developers integrating it into their products. At the same time, the model runs smoothly on consumer-grade GPUs with less than 16GB of VRAM, lowering the barrier to professional-quality AI image generation. Z-Image also offers specialized variants for turbo generation and precise image editing, allowing users to perform everything from subtle local edits to global style transformations with high consistency. With robust bilingual text rendering in Chinese and English and a strong understanding of world knowledge and cultural concepts, Z-Image empowers global creators, brands, and developers to build multilingual visual experiences that are beautiful, accurate, and fast.
