How to Create AI Images with ComfyUI: A Beginner’s Guide

If you want precise, professional control over AI image generation, ComfyUI is the tool to learn. Its node-based interface lets you build reusable workflows instead of relying on a single prompt box. Here is how to create your first AI image.

Step 1: Install ComfyUI

Head to ComfyUI and download the installer for your operating system. The one-click package includes everything you need, including a compatible Stable Diffusion model so you can start right away.

Step 2: Launch and Generate a Base Image

Open ComfyUI and you will see a default workflow with nodes for loading the model, sampling, and saving. Type a prompt in the positive prompt node and click Queue. Within seconds you will get your first generated image.

Step 3: Understand the Nodes

The core nodes are Checkpoint Loader (which model), CLIP Text Encode (your prompt), KSampler (the generation settings), and Save Image. Drag connections between them to change how your workflow behaves.

Step 4: Add ControlNet for Precision

To guide the composition, add a ControlNet node before the sampler. Upload a reference image to control poses, edges, or depth, and ComfyUI will respect that structure while generating your image.

Step 5: Refine with LoRA

Add a LoRA loader node to influence style or characters. Connect it to the model and CLIP nodes, adjust the strength, and preview how the LoRA changes your results.

Step 6: Practice and Experiment

The best way to master ComfyUI is to experiment. Adjust the sampler steps, denoise, and seed values to see how each affects the output. Save your favorite workflows for reuse.

Final Thoughts

ComfyUI rewards a little patience with enormous creative control. Learn the basic nodes, add ControlNet and LoRA, and you will unlock a professional-grade AI image studio for free.
