AI studioChapter 4
Images at home
You can make your persona’s art on your own computer, with no monthly bill and nothing sent to a service. What decides it is your graphics card, your disk and the licence of the model you pick.

- Local generation runs on your graphics card. Its memory decides which models load and how fast they run.
- ComfyUI is a free program that runs open image models on your own computer, even offline.
- Every model comes with a licence. Some allow commercial use, some don’t, and it can change between versions of the same model.
- One model file can take 20 to 40 GB, so plan a drive for them.
- Work in small rounds: describe, generate several, compare, change one thing, write down what worked.
You will learn
- What a GPU and its memory change for image generation.
- What ComfyUI is and why its files can carry your recipe.
- Which open model families make anime art, and what their licences allow.
- How much disk space local generation needs.
- A method for working with AI that gets you to the picture you want.
What your computer needs
Local generation means the model runs on your own computer. Nothing is sent to a service, and there’s no bill per image. The part that matters most is the graphics card, the GPU, and its own memory, called VRAM. More VRAM lets bigger models load in one piece, and that makes them faster. Vivian’s field notesFirst-hand experience, not a study.
You need less than you’d think. ComfyUI says it can run even the biggest open models on 4 GB of VRAM and 8 GB of normal memory, by moving parts of the model in and out while it works.

What ComfyUI is
ComfyUI is free software that runs image models on your computer. You build the job as a graph of boxes joined by wires: load a model, write the prompt, generate, save. VerifiedChecked against the original source.ComfyUI README (opens in a new tab) Accessed 7 November 2026. Its core runs fully offline and downloads nothing unless you ask.

ComfyUI can save a whole workflow and recover it, seeds included, from a picture it made. VerifiedChecked against the original source.ComfyUI README (opens in a new tab) Accessed 7 November 2026. That’s handy as a recipe, and it’s also a leak: a file that carries its recipe shows your prompt and settings to anyone who opens it in the same tool.

The open model families
A model family is a base model and the versions built on it. For anime art, most people start from a family trained on anime pictures. Vivian’s field notesFirst-hand experience, not a study.

The pictures
What you may do with what you make: post it, sell it as a custom, use it on a paid page. Vivian’s field notesFirst-hand experience, not a study.
Running a model at home doesn’t take you outside its licence. Read it for the exact version you download, because the licence can change from one version to the next. Vivian’s field notesFirst-hand experience, not a study. None of these licences names findom. UnverifiedPlausible, not proven yet.

What my own tool makes
I built my own image tool with this method, and one picture takes me about a minute. Here are six pictures of Vivian it made, as they came out. Vivian’s field notesFirst-hand experience, not a study.
Six pictures from my own tool
Made by Vivian with an image tool she built herself, about a minute per picture.Vivian’s field notesFirst-hand experience, not a study.
The tool came from the same steps as below: a plain description, many small tries, a board to compare them and a recipe sheet for every keeper. Vivian’s field notesFirst-hand experience, not a study.
How I work with AI
This is my method. It works with a model at home or a service online, for pictures and for words. Vivian’s field notesFirst-hand experience, not a study.
Tutorial
My method, step by step
Step 1 of 7
Say what you want in plain words
Describe the picture the way you’d tell a friend: who, where, the mood, the colours, what she’s doing. Then ask an AI assistant to turn it into a prompt. Vivian’s field notesFirst-hand experience, not a study.
Do this. Write one paragraph before you touch any setting.
Common mistake. Copying a long list of keywords from someone else’s picture. You won’t know which word does what.
Start small
Use a small size and a fast setting while you look for the idea. Go big only once you like it. Vivian’s field notesFirst-hand experience, not a study.
Do this. Keep the first rounds quick, so you can afford many of them.
Generate several
One picture tells you nothing. Make four to eight with the same prompt, so you see what the prompt does and what’s luck. Vivian’s field notesFirst-hand experience, not a study.
Compare on a board
Put the results side by side in one folder or on one page, and mark the ones that work. Look at them the next day too. Vivian’s field notesFirst-hand experience, not a study.
Do this. Pick for the face first. Hands and background are easier to fix later.
Keep a recipe sheet
For every keeper, write the date, the model, the prompt, the settings and one line on why it worked. Vivian’s field notesFirst-hand experience, not a study.
Common mistake. Trusting your memory. Three weeks later you’ll never find that face again.
Fix one thing at a time
Change one word or one setting per round. If you change three things and it gets better, you don’t know which one did it. Vivian’s field notesFirst-hand experience, not a study.
Keep the originals
Save the full-size file and its recipe in a private folder. Post copies only. Vivian’s field notesFirst-hand experience, not a study.
Common mistake. Editing your only copy. You lose the version you could have gone back to.
Ticks stay on this page only. Nothing is saved or sent.
Every step is done.
From words to a prompt
Tap every message that shows a red flag. There are two.
Example conversation. Invented for this exercise.

Selling customs made at home
You want to sell custom pictures of your persona made on your own computer.
- The licence still applies at home. Some forbid paid sites or need you to ask first.
- Right. Note which version you used on your recipe sheet, too.
- Its licence forbids running it on any website or app that makes money.
Remember it
- VRAM decides what loads and how fast. You can start with a small card.
- ComfyUI runs offline, but its files can carry your prompt. Post clean exports.
- Read the licence of the exact version, for the model and the pictures.
- Plan a drive: one model can take 20 to 40 GB.
- Describe, generate several, compare, change one thing, write it down.
