 In the first time you launch the software, it will automatically download models:
 
 1. It will download [sd_xl_base_1.0_0.9vae.safetensors from here](https://huggingface.co/stabilityai/stable-diffusion-xl-base-1.0/resolve/main/sd_xl_base_1.0_0.9vae.safetensors) as the file "Fooocus\models\checkpoints\sd_xl_base_1.0_0.9vae.safetensors".

+Note that the minimal requirement is **4GB Nvidia GPU memory (4GB VRAM)** and **8GB system memory (8GB RAM)**. This requires using Microsoft’s Virtual Swap technique, which is automatically enabled by your Windows installation in most cases, so you often do not need to do anything about it. However, if you are not sure, or if you manually turned it off (would anyone really do that?), you can enable it here:
