Thanks to the developers of the mflux project, especially the initiator @filipstrand and active contributor @anthonywu, for making it easier and more efficient for Mac users to generate flux model images. These contributions are truly delightful—thank you!

Update Announcement

About This Update:

• The ControlNet node integrates images and intensity to distinguish it from img2img — contribution from @InformEthics.

This is the first time other contributors have participated in updating this plugin. Thanks @InformEthics.

Previous Updates Recap:

• Bring back the missing metadata

The Quick MFlux Generation node has metadata enabled by default (set to True). This means that the generated images will be automatically saved under ComfyUI/output/Mflux, along with a JSON file that shares the same name as the image.

In the ComfyUI directory, you can also use the mflux-generate --config-from-metadata command to load a JSON file and use the original mflux to generate images.

Example:

Mflux_Metadata

The advantage of the original version is its clean memory management: it automatically releases memory after each generation, as can be observed in the Activity Monitor.

If you'd like to experience the original mflux, this provides an additional option.

• Added progress bar and interruption functionality in ComfyUI. Click the built-in cancel button (the cross icon) to interrupt.
• Customizable file paths.
• Image-to-Image generation.

mflux has been updated to version 0.4.1. To experience image-to-image generation, please upgrade in ComfyUI with:

pip install --upgrade mflux

Usage Instructions

Right-click to create nodes:

Under MFlux/Air:

• Quick MFlux Generation
• MFlux Models Loader
• MFlux Models Downloader
• MFlux Custom Models

Under MFlux/Pro:

• Mflux Img2Img
• MFlux Loras Loader
• MFlux ControlNet Loader

Or double-click in the blank area of the canvas to bring up the node search box, and directly search for the node names by the keyword “Mflux.”

Basic Path Explanation

Quantized Models:

ComfyUI/models/Mflux

LoRA:

ComfyUI/models/loras

I usually create an Mflux folder under models/loras to manage the LoRAs compatible with Mflux, storing them uniformly. Therefore, in my example, the retrieved files should be Mflux/*******.safetensors.

Native Full Models & ControlNet:

Yourusername/.cache

Although the current node Mflux Models Downloader can automatically download, I would still like to share a few links to quantized models as a token of appreciation:
