ComfyUI Extension: Core ML Suite for ComfyUI

Core ML Suite for ComfyUI Introduction

Welcome to ComfyUI-CoreMLSuite! This extension provides a set of custom nodes for that allow you to use Core ML models in your ComfyUI workflows. These models are designed to leverage the Apple Neural Engine (ANE) on Apple Silicon (M1/M2) machines, enhancing your workflows and improving performance.

In simple terms, Core ML models can help your ComfyUI work faster and more efficiently. For instance, during tests on an M2 Pro 32GB machine, the use of Core ML models sped up the generation of 512x512 images by approximately 1.5 to 2 times.

How Core ML Suite for ComfyUI Works

ComfyUI-CoreMLSuite integrates Core ML models into ComfyUI workflows. Core ML is a machine learning framework developed by Apple, designed to run machine learning models on Apple devices. By using Core ML models, you can take advantage of the Apple Neural Engine (ANE) for faster and more efficient processing.

Think of Core ML models as specialized tools that can accelerate your image generation tasks. For example, if you are generating images using Stable Diffusion, Core ML models can significantly reduce the time it takes to produce high-quality images.

Troubleshooting Core ML Suite for ComfyUI

Here are some common issues and their solutions:

Issue: Models Take a Long Time to Load

Solution: Using compiled models (.mlmodelc files) instead of .mlpackage files can reduce loading times.

Issue: Model Conversion Fails

Solution: Ensure that the model files are correctly placed in the models directory and that the required dependencies are installed.

Issue: Errors During Image Generation

Solution: Check that the correct compute unit is selected and that the model is compatible with the expected parameters.
