Why would anyone build with this?

REASON 1

Generate commercially licensed AI images locally on a Mac without cloud costs.

REASON 2

Load a pre-tuned ComfyUI workflow instead of guessing model settings yourself.

REASON 3

Run image generation on lower RAM Macs using the lighter model variant.

REASON 4

Avoid known Apple Silicon rendering bugs like black frames and stuck batches.

Needs a Mac with roughly 48GB unified memory for the default setup, or a lighter alternative model for less RAM.

Wtf does this do

This project is a recipe for running Krea 2, an AI image generator, entirely on a Mac with Apple Silicon chips, instead of needing a cloud service or an expensive graphics card from another brand. Krea 2 turns text descriptions into photos, and it is one of the few image models whose output you are allowed to use commercially, since it comes with a business friendly license. The repository is not really source code you install, it is a single workflow file for a tool called ComfyUI, a visual app for building AI image pipelines. You load this file into ComfyUI and it already knows which three model files to download and where the settings should sit, based on many hours of trial and error by the author. It also includes an optional add-on node that can be turned on for slightly more realistic looking skin in portraits. Running the default version well needs a Mac with a large amount of unified memory, roughly 48 gigabytes, because the model files together take up tens of gigabytes. For Macs with less memory, the README documents an alternative, lighter version of the model that trades a small amount of setup complexity for using about half the memory. Most of the document is a detailed list of quirks specific to running large AI image models on Apple hardware, such as image batches needing to be rendered one at a time, a particular setting that must never be set to a certain value because it produces a solid black image, and reminders not to add an extra technical adjustment that the tool already applies automatically. These notes exist so that someone trying the same thing does not have to rediscover each problem themselves. This is aimed at people comfortable installing ComfyUI who want to generate AI images locally on a Mac, particularly anyone who wants a commercially licensed model without paying for a cloud image generation service or a dedicated graphics card.
