>>84521630Oh kek, we really need to start from the top. You can check the wiki in the op, it has a good start guide (kinda outdated but will get you started) to let you know what all those are but in short
model/checkpoint - This is what generates the images,
LoRA - are a way to add stuff the model doesn't know, characters/styles/concepts etc.
Vae - for XL there is just one and most model comes with it so dont't have to worry about this one was more important in the prev generation of models.
Upscalers - Download this, it should let you easily download these and other custom nodes you may need later
https://github.com/ltdrdata/ComfyUI-ManagerAll the stuff listed above (except upscaler) you can find at
https://civitai.com/For the checkpoints, if you want to do porn you want to use the Pony models, for general anime you want to use animagine based models (There are a few more now but to get your feet wet first)
Btw what are the specs for your computer? for XL you need a fairly beefy rig (8gb VRAM GPU min, can go lower but will be painful to gen kek)
