Enhanced Image to Image Upscaling with Flux GGUF and ComfyUI (Low-VRAM )

Introduction

Welcome to the digital playground of AI creativity! Today, we’re excited to dive into an exhilarating journey that will supercharge your AI image generation workflow using the incredible Flux models and GGUF files. If you’ve been yearning to enhance your current artistic endeavors, this article will introduce you to some fantastic techniques that allow you to use your images as a springboard for AI creativity—an awesome image-to-image workflow.

Why Image-to-Image?

You might wonder why you should venture into image-to-image generation when text-to-image models seem to be thriving. The answer lies in the vast possibilities this workflow offers. Imagine transforming a cool photo, a hand-drawn sketch, or any screenshot into a myriad of variations while preserving the core essence of the original image. This technique enables blending art styles, infusing fantastical elements into photos, or even entirely reimagining existing visuals, making it an indispensable tool in your creative arsenal.

Key Features

Control Over Variations: You can fine-tune how much the original image influences the output, enabling more controlled transitions and styles.
Visual Consistency: Maintain visual harmony across varied images by using one base image as a reference.
Incorporating Styles: Sprinkle in your favorite LORAs (Latent Optimized Representation Algorithms) to customize the styling of your creations.

Setting Up ComfyUI

Before we launch into creating, let’s ensure your setup is primed and ready. Download the required workflow from the provided Google Drive link and follow a previous guide if you need a refresher on installing ComfyUI and relevant nodes.

Install ComfyUI Manager: Clone the ComfyUI Manager repository into your custom nodes folder and restart ComfyUI.
Load the Workflow: Access the ComfyUI web page and load the "Flux Image to Image Workflow."
Install Missing Nodes: If you see red error messages regarding missing nodes, navigate to the manager tab to install them.

Getting Your Models Ready

We need several models for successful image generation:

Flux Models: Search for “flux GF” and choose either the dev or quantized GF model.
Clip Models: Install the “Google T5 fp8 clip model” and the “clip L by comfy Anonymous.”
Flux V Model: Search for “flux V” and install the “flux point1 V model.”
Upscaler: Search for “full” and install the “full hearty model” for decent upscaling outputs.

You can supplement your model collection by downloading LORAs from Hugging Face or Civit AI.

Generating Images

With your models ready, let’s dive into generating images!

Upload Your Base Image: Start by uploading the image that will serve as your foundation.
Create a Descriptive Prompt: Write a prompt that captures the essence of your original image. Consider using multimodal models like ChatGPT to analyze your image for robust descriptions.
Adjust Generation Settings:
- Steps: A typical recommendation is around 20 steps for a nice balance between quality and speed.
- Denoise Strength: Adjust this setting to control how much the original image will alter during the generation process. Values between 0.50 and 0.91 work well for subtle adjustments.
- Batch Size: Enhance your workflow efficiency by adjusting the batch size to generate multiple images at once.
Hit the Generate Button: Once everything is set, click the Q Prop button and watch the magic happen! Don’t hesitate to experiment with different prompts and configurations to find what works best for you.
