Open Photoshop. Go to the top menu: Plugins > Alpaca (or Window > Extensions > Alpaca). A floating panel will appear.

Step 4: Model Selection Inside the plugin, you will see a dropdown. For beginners, select "Alpaca XL" or "Stable Diffusion." If you have a modern NVIDIA GPU (8GB+ VRAM), toggle "Local Mode" for infinite free usage.
