Z-Image-Turbo in Stable Forge UI Neo - One Click Windows Installer

Z-Image-Turbo is now supported in Stable Diffusion Forge UI Neo, and this guide shows you how to get it running on Windows with a one-click installer. Z-Image-Turbo is a 6B-parameter, few-step text-to-image model focused on fast, photorealistic generation that still fits on consumer GPUs with around 6 GB of VRAM using lightweight quantization methods.

This post walks through using the one-click Windows installer that sets up Stable Forge UI Neo with the full Z-Image-Turbo stack: Forge, PyTorch/CUDA, Sage, Flash Attention 2, Triton, the Z-Image-Turbo GGUF model, Qwen3 4B text encoder, and the VAE, all dropped into the right folders automatically.
