Novel AI Diffusion is a Stable Diffusion service/setup that's anime-oriented (with a furry model in beta if you're into that) and is braindead-easy to use.
The service requires a subscription of 15$/month minimum, with a recommended 25$/month plan to generate an unlimited amount of images at 640x640, 28 steps maximum. While it may seem somewhat steep you also need to remember that you get access to Novel AI's other features (arguably the main ones) such as the Novel part of the service (which is surprisingly fun to use even if you have zero interest in writing a story) and the excellent TTS. With the 25$/month tier you get 10,000 generation tokens that you can use to pay for larger (up to 1024x1024, 50 steps) images. Said large images cost about 25 tokens at max settings, 20 if you use 40 steps (which seems to be the euler_ancestral sampler's soft cap). Extra currency costs 3.79/6.49/10.99 USD for 2000/5000/10,000 tokens respectively.
Some of their hardware has been quarantined after a very serious breach so the service isn't running as fast nor as well as it should right now - but on a normal day it takes 5 seconds flat to generate an image at the free settings (28 steps, up to 640x640, usually 512x768 portrait or 768x512 landscape resolutions) which makes constant prompt-tweaking much less frustrating than self-hosted SD.
"But Xeraser, I don't want to pay/I'm too cheap/I just bought a 3090 Ti from a failed crypto farm!"
You're in luck - mostly.
Novel AI's models, frontend and backend (yes, you can host the SITE ITSELF on your hardware and get a nearly 1:1 experience) have been leaked, all of which you can find in the guides below.
Requires making a SD setup: NAI leaked model (full leak, 50+ GB but not everything is required) to use with Stable Diffusion's webui: https://rentry.org/sdg_FAQ#how-do-i-setup-the-leaked-novelai-model
Requires NO SD setup, runs on Windows/Linux, REQUIRES an Nvidia card with 8GB+ VRAM: NAIFU ("full" model + frontend + backend): https://rentry.org/sdg_FAQ#naifu-novelai-model-backend-frontend (you can use the other models from the full leak above with this or other SD models entirely, read the guide at the bottom of the section)
xformers - do you need them? Possibly, possibly not. They WILL affect the final result, possibly for the worse. If in doubt just don't bother.
IMPORTANT - HERE'S WHY YOU MIGHT WANT TO PAY FOR THE SERVICE:
How do I use the furry model with the leak? Is it even included?
I don't know and I don't care to know until it can give me actual Imp Midna.

xformers - do you need them? Possibly, possibly not. They WILL affect the final result, possibly for the worse. If in doubt just don't bother.
IMPORTANT - HERE'S WHY YOU MIGHT WANT TO PAY FOR THE SERVICE:
- Speed. On a 1080 Ti the default settings that NAI uses take nearly 4 times longer to generate an image or roughly 18.x seconds VS NAI's 5 seconds flat. On maximum setting (1024x1024, 50 steps) it takes over two full minutes vs NAI's 15 seconds average). With how RNG-y Stable Diffusion is the extra time required will make it significantly less fun and more frustrating to mess around with.
- Power/Time/Price ratio. Considering the example above it might end up being cheaper vs your electricity bill depending on where you live (especially Europe)
- A significant one: constant updates and fixes. With NAI proper you'll get constant under-the-hood updates, possibly new/updated models (the furry one will be updated to get it out of beta), QoL things (for example you can now drag and drop a previously generated image to copy every setting or every setting PLUS the seed automatically), support from the devs and more. Possibly none of these will come to NAIFU (leaked frontend+backend+model) unless another huge leak/breach happens (remember, a 0-day was used to get the first leak, don't think that will happen again anytime soon)
While some of these MAY be possible (mostly the QoL updates) you're still at the mercy of 4chan anons. - Consistency and overall quality: NAIFU results seem to be 10-20% worse than NAI proper (might be even worse with the leak + webui) and this most likely has to do with the above. Identical settings and seeds will not produce 1:1 results between them: NAI outputs might look worse in NAIFU, NAIFU outputs might look better in NAI, etc. This is probably due to NAI constantly fucking with/tweaking their sampler as even NAI to NAI results seem to vary slightly on a daily basis when using identical settings and seeds (but still closer than NAI vs NAIFU)
