Nodes:

<details> <summary>Efficient Loader & Eff. Loader SDXL</summary> <ul> <li>Nodes that can load & cache Checkpoint, VAE, & LoRA type models. (cache settings found in config file 'node_settings.json')</li> <li>Able to apply LoRA & Control Net stacks via their <code>lora_stack</code> and <code>cnet_stack</code> inputs.</li> <li>Come with positive and negative prompt text boxes. You can also set the way you want the prompt to be <a href="https://github.com/BlenderNeko/ComfyUI_ADV_CLIP_emb">encoded</a> via the <code>token_normalization</code> and <code>weight_interpretation</code> widgets.</li> <li>These node's also feature a variety of custom menu options as shown below. <img src="https://github.com/LucianoCirino/efficiency-nodes-media/blob/main/images/nodes//NodeMenu%20-%20Efficient%20Loaders.png" width="240" style="display: inline-block;"> note: "🔍 View model info..." requires <a href="https://github.com/pythongosssss/ComfyUI-Custom-Scripts">ComfyUI-Custom-Scripts</a> to be installed to function.</li> <li>These loaders are used by the XY Plot node for many of its plot type dependencies.</li> </ul> <img src="https://github.com/LucianoCirino/efficiency-nodes-media/blob/main/images/nodes/NODE%20-%20Efficient%20Loader.png" width="240" style="display: inline-block;"> <img src="https://github.com/LucianoCirino/efficiency-nodes-media/blob/main/images/nodes/NODE%20-%20Eff.%20Loader%20SDXL.png" width="240" style="display: inline-block;"> </details>  <details> <summary>KSampler (Efficient), KSampler Adv. (Efficient), KSampler SDXL (Eff.)</summary>

Modded KSamplers with the ability to live preview generations and/or vae decode images.
Feature a special seed box that allows for a clearer management of seeds. (-1 seed to apply the selected seed behavior)
Can execute a variety of scripts, such as the XY Plot script. To activate the <code>script</code>, simply connect the input connection.

A group of node's that are used in conjuction with the Efficient KSamplers to execute a variety of 'pre-wired' set of actions.
Script nodes can be chained if their input/outputs allow it. Multiple instances of the same Script Node in a chain does nothing.
