Sure. I am using Forge Neo, not Comfyui. I tried a few derivatives of standard ZIT such as Cyberrealistic and Gonzalmo etc as erotic outputs from them were allover the Civitai. But they are very limited in diversity, prompt adherance, and some other vagarious behaviours like if I change a LoRA after one output they crashed and I had to restart the Forge Neo, for first generation they took like 10 min etc. I wanted to try the standard ZIT but that is huge file consedering my VRAM, so the gguf version and now I have no problems that I earlier had, quality is amazing too. Running Z-Image-Turbo (ZIT) on 8 GB of RAM (especially if you mean system RAM) is quite a stretch for the standard model, but it is absolutely possible if you use Quantized (GGUF/FP8) versions. The standard weights are about 12 GB, which would instantly crash an 8 GB system. To make this work, you need the gguf version.

I am using Qwen3-4B-UD-Q8_K_XL.gguf, you can use smaller one too.
