How to Install Stable Diffusion for AMAZING AI Art in 2025! (Forge)

This tutorial demonstrates how to install and configure Stable Diffusion using Forge UI, a free and open-source interface for running AI image-generation models like Stable Diffusion 1.5, SDXL, and Flux on NVIDIA GPUs (4GB–24GB VRAM). Learn to integrate models from CivitAI and Hugging Face, optimize settings such as sampling steps and CFG scale, and utilize negative prompts for precise outputs!

Great job at explaining, kudos! Got everything installed. Able to generate images in 35 seconds with an RTX 2060 6g ram. I will watch your other video about the detailed tweaks and refiner

[rokkson]

Cool video! Just wanted to note—I’m running SDXL smoothly on 8GB VRAM without issues. (1024 x 1024 and higher, SDXL, Forge + Krita AI Plugin, RTX 2080)

[aaronhan]

Great video. Looking forward to the Mac guide

[fritzhensel]

Thanks for the video! Since I'm a Mac user, I would really appreciate a guide for Mac. Hopefully, it'll be available soon. I'm also completely new to this area and a bit overwhelmed by all the UIs, models, and AI. Perhaps I can still get a clear overview.

Great job with the video. I am a complete beginner (sorry!) I installed forge, then followed your link to the stable diffusion 1.5 hugging page, but am lost from there. There seems to be a lot of talk about "diffusers" and "weights"... but i cannot find any link to actually download this model..

[GetPianoLessons]

So is "Comfy AI" the same thing as "Forge" just a different brand? Also what is the relationship between these terms and "Hugging Face" and "Civit AI"? These words are spoken so often but they are not clear to me, thanks.

[nonovoctf]

i have this problem on stable diffusion, when i click on generate : ValueError: Failed to recognize model type!

just noticed the video of you talking is IA, how you did it?

[colemcgirth]

You mentioned that you would be making a tutorial for AMD GPU's. Any update on that?

[jaredjones]

So this is how you install stable diffusion? I thought you had a do a lot of work in the cmd. Or at least that’s what I did when I installed it last weekend. I deleted everything and want to do a fresh install.

[abhicreation]

If i want to install what requirements need my laptop and is this free?

[damianlazo]

using stable diffusion its worth in 2025?

[mickeyhavoc]

I keep getting a runtime error? Any ideas? RuntimeError: CUDA error: no kernel image is available for execution on the device CUDA kernel errors might be asynchronously reported at some other API call, so the stacktrace below might be incorrect. For debugging consider passing CUDA_LAUNCH_BLOCKING=1. Compile with `TORCH_USE_CUDA_DSA` to enable device-side assertions.

When I tried to install, my antivirus intercepted something and deleted it (something to do with python). I ended up trying to install python seperately, then running the forge install. Still couldn't install, it didn't recognise python. Then, when i tried to delete the files I had downloaded, every time I try to delete them -windows explorer freezes. I downloaded them from the link you provided

[romaans]

Can we get Stable Diffusion 3.5 Medium in 4GB VRAM

[Lost_Dawn]

Big warning: always have internet at the ready, or end up like me with no way to use base models, vaes or loras other than the single one you downloaded when you did the installation. Funny how it's supposed to be a offline art generator but yet you can't just copy over the CivitAI models you already downloaded on your computer. They really need to put a notice up, and it would be nice if the vae automatically was selected for your base model when you change it, but given it's been, what a year since the last update, it's safe to assume Forge AI is almost dead. And for that matter probably Swarm as well. I guess the only real option is Invoke, which was a nightmare to try and understand, but what choice is there?

[ParadiseParadises]

got a 5090 and i just cant get it to work 😭

[egg]

Cant seem to make a flux LORA work on forge
Even have a checkpoint by the same persona downloaded and it ignores the model

Anyone got a tuto for it?

[nmbd]

Mine open on microsoft edge, anyway I can open in on google chrome instead

How do we know Github files are safe from malware/trojans? Also, how do you uninstall Stable Diffusion? Just delete the extracted folder?
