AC_Super_Loras

AC_Super_Loras is the "keep four LoRAs handy, flip between them" node. It takes a MODEL and CLIP plus four pre-filled LoRA slots, and a Select dropdown decides which single LoRA actually gets applied. Instead of hunting for and rewiring a LoraLoader every time you want to try a different style, you configure four at once and switch with one click.

How it works

Under the hood it's the stock load_lora_for_models call, exactly what a core LoraLoader runs. The key detail is in the Select behavior: only the selected slot's LoRA is applied, with that slot's strength_model and strength_clip. The other three slots are just parked filenames - they cost no VRAM and do nothing until selected. The node also caches the most recently loaded LoRA file internally, so toggling between already-loaded files is fast.

The inputs

• model / clip - from a checkpoint loader.
• lora_name_1 through lora_name_4 - dropdowns into your models/loras folder, each with its own strength_model and strength_clip. The strength range is generous: −20 to 20, so negative values work as anti-LoRA subtraction.
• Select - lora_1, lora_2, lora_3, or lora_4. This is the whole point of the node.

The outputs

MODEL and CLIP, with the chosen LoRA baked in. Feed them to a sampler or to AC_Super_KSampler.

Where people get burned

The most common mistake is expecting the four slots to stack. They don't - this node applies exactly one at a time. If you want two LoRAs stacked (say a style plus a character LoRA), that's AC_Super_Lora&LCM in Merge mode, or just chain two LoraLoaders. The other gotcha is sharing: a workflow with four filled slots only loads cleanly for someone who has all four LoRAs installed. And remember, unlike the checkpoint version of this pattern, Select applies the LoRA on top of whatever model/clip you wired in - so this node is the "swap the style" knob, not a model picker.
