Run Z-Image Turbo on low VRAM GPUs using GGUF models in ComfyUI
Press play on the video. It'll jump straight to the section that answers the
title above — no need to watch the full video.
Learn how to download and configure compressed GGUF models and quantized text encoders to run Z-Image on GPUs with as little as 4GB VRAM.
Low VRAM Capability
Using the 'Q3 small GGUF' model (approx. 3.79 GB) allows Z-Image Turbo to run comfortably on GPUs with as little as 4 GB of VRAM.
Matching Quantization Levels
For optimal compatibility and performance, attempt to match the quantization level of the text encoder (e.g., Q4 Medium) with the quantization level of the main GGUF model.
Negative Prompt Usage
Z-Image Turbo generally does not require a negative prompt to function correctly, though the input field remains available in the workflow.
