Welcome back to WTF is 3D!!! The series that breaks down complicated 3D and AI tools in a way that anyone can understand.
I was planning to take a short break from the WTF series, but something too good came up that I had to write one more.
This week's question comes from a reader who asked:
"I keep hearing people talk about ComfyUI, and I keep pretending like I know what it is, but I have no clue. Does it have something to do with AI and Blender or something? Can you please help me out?"
It’s a great question.
So in this article, we're diving into what ComfyUI actually is: a node-based interface that connects different AI applications together into one customizable workflow.
What is ComfyUI?
ComfyUI is an open-source tool that gives you a node-based system for visually crafting creative workflows, including AI tools.
Each node represents a specific function:
Load an AI model
Enter a text prompt
Set the image size and settings
Choose how the AI generates the image
Save or process the output
Instead of coding, you visually connect the nodes to create custom, flexible pipelines.
In its base form, ComfyUI acts as a "connector" between AI models like Stable Diffusion, ControlNet, LoRA adapters, samplers, image processors, and more, all using a visual interface.
You build exactly the workflow you want, see every step, and can tweak everything at any point.
Examples of Workflows
Here are a few real-world things people have built using ComfyUI:
Text-to-Image Generation Pipelines
Example: Creating AI Art with ComfyUI — chaining prompts, samplers, and upscalers into a polished pipeline.
AnimateDiff Setups
Example: AnimateDiff in ComfyUI Tutorial — building animated frame sequences with motion controls.
Style Mixing and Model Blending
Example: Mixing Models and Styles — combining different checkpoints like realism and anime.
Batch Image Generation
Example: Automating Batch Outputs — generating hundreds of variations automatically.
Inpainting Workflows
Example: Inpainting with ComfyUI — editing specific parts of an image using masking and AI regeneration.
Why artists love it
Artists love ComfyUI because it gives them complete control over the creative process. Instead of relying on a black box where the AI makes mysterious choices, they define exactly how the AI should process each request. Every step in the workflow is transparent and adjustable, allowing for precise tuning, experimentation, and troubleshooting. This clarity and control enable the ability to push creative boundaries and iterate quickly on ideas.
Workflows can also be saved and shared easily as .json files, making it simple to reuse complex setups or collaborate with others. It's easy to trade workflows across the community or build a personal library of techniques to revisit at any time. This encourages artists to experiment without the fear of losing their best setups.
One of the biggest reasons artists are drawn to ComfyUI is that it allows them to create incredibly complex AI workflows without needing to write any Python scripts or technical code. Everything is done visually. Whether you want to blend multiple models, run conditional branches, or layer different AI techniques together, you can do it all through a no-code interface. This makes high-level AI experimentation accessible to artists, designers, and creators who aren't programmers.
ComfyUI empowers users to feel like engineers of their creative processes, giving them the ability to fine-tune, expand, and truly customize how AI contributes to their work.

Final Thought
ComfyUI isn't just another AI tool — it's a true creative playground for anyone ready to take control of how their ideas come to life. By removing the need for coding and making the process visual and modular, it opens the door for artists and creators to design workflows as unique as their imaginations. Whether you're a seasoned professional or just starting out, diving into ComfyUI gives you the power to move beyond presets and push AI to work for you, not the other way around. If you're looking to expand your creative toolkit and actually understand how these systems fit together, there's no better place to start.
