d. The fuse_lora() method allows you to fuse the LoRA weights directly with the original weights of the underlying model. This way, you’re only loading the model once which can increase inference and lower memory-usage. You can use PEFT to easily fuse/unfuse multiple adapters directly into the model weights (both UNet and text encoder) using the fuse_lora() method, which can lead to a speed-up in inference and lower VRAM usage. For example, if
