A Beginner's Guide to Stable Diffusion

What Stable Diffusion is

Stable Diffusion is a family of text-to-image models released with open weights and documentation, later extended by many community interfaces. A beginner should start with one named version and one named interface, not with a pile of unofficial installers.

The Korean original is a getting-started note. This page keeps that job and refuses unsourced hardware claims.

How to start, then the install or web-app instructions for the interface you choose. If a page lists a recommended GPU memory size, quote it with a date. If it does not, do not fill the gap from memory.

A hosted demo is a valid first step when a local install is unclear. Check whether the host keeps prompts or images, and what it costs after a trial.

Prompts, safety, and other people's work

A prompt is an instruction, not a guarantee of a particular style or face. Do not paste other people's unpublished images or a person's likeness into a tool if your rules or the law around you restrict that use.

Safety filters and license terms differ by build. Read them on the page you actually use.

Limits

Quality, speed, and hardware notes go stale quickly. Re-read the current docs before you buy a card or quote a memory size in a report. This is a beginner explainer, not a benchmark.

FAQ

How much VRAM do I need?
Hardware needs change by model, resolution, and interface. Read the current official or project documentation for the build you are installing, or use a hosted service whose page states its own limits.
Is this a license to use any image I generate?
No. Read the model license, the interface terms, and the copyright rules that apply to your output and to any training or input images you use.
Do I have to install it locally?
No. Official and third-party hosted interfaces exist. Compare their terms and costs on their own pages, dated.
