ComfyUI-nunchaku
Nunchaku ComfyUI Node. Nunchaku is the inference that supports SVDQuant. SVDQuant is a new post-training training quantization paradigm for diffusion models, which…
Nodes (16)
The deprecated FLUX depth map node
The 4-bit Flux loader that's faster than fp8 or GGUF
Image-prompt a 4-bit Flux from a reference
Load a LoRA into a 4-bit Nunchaku Flux model
Stack up to 15 LoRAs on a 4-bit Flux in one node
Inject a reference face into a 4-bit Flux
Set up IP-Adapter for a 4-bit Nunchaku model
Reassemble a split Nunchaku model into one file
The older PuLID face-apply node (use the V2)
The older PuLID loader (use the V2)
Load PuLID face identity onto a 4-bit Flux
Run 20B Qwen-Image in 4-bit on a normal GPU
The older 4-bit T5 loader (use V2 instead)
Load the 4-bit T5 encoder for Flux
The node that installs Nunchaku's actual engine
Run Z-Image Turbo in 4-bit, even faster
This repository provides the ComfyUI plugin for Nunchaku, an efficient inference engine for 4-bit neural networks quantized with SVDQuant. For the quantization library, check out DeepCompressor.
