Zimage

Z-Image is an advanced open-source image generation foundation model built around a Single-Stream Diffusion Transformer (S3-DiT) architecture. With 6 billion parameters, Z-Image aims to deliver performance comparable to larger proprietary models while remaining efficient enough to run on consumer GPUs. The project focuses on fast, controllable synthesis, strong instruction-following, and exceptional bilingual (Chinese + English) text rendering.

Z-Image ships in multiple variants tailored to different needs: Z-Image-Turbo (distilled, ultra-fast 8-step inference), Z-Image-Base (full non-distilled foundation), and Z-Image-Edit (specialized for natural-language-driven image editing). The model is fully open-source under the Apache 2.0 license and can be deployed locally for free or used via paid hosted compute on the Z-Image platform.
