LoRA or LoRA Base?

[StripedPuppy]

In the models tab, what is the difference between LoRA and LoRA Base for LoRA models?

I've noticed I can run 7b and 13b LoRA's under LoRA Base, but not LoRA due to insufficient extra RAM.

lora base is intended to select the original f16 model weights (a higher quality model to use as a base for the layers modified by the adapter.)
