All(-ish) models are available to use for free with the links provided below, if you are unsure about a model then you can try them before downloading.

Future Releases

As I can not keep up will model development with my current situation, I will be uploading my model merging resources here. Designed specifically for merging into custom models of your own, they should provide some worth for future SDXL/Pony model merging. I will update this description as I upload more of my resources.

TheTerribleTimmy! - (Illustrious Realism Model)

Like the name? Thought about it for around five seconds. Anyways, as you may have already guessed, this is further development upon MyPreciousJimmy!. I said I was going to adjust the lighting, and so I did, literally right after I got out of a thirteen hour shift. One sleepless night later, boom, it's done-ish. Lighting is less flat. More vibrant coloring as well. I also increased the detail and overall quality of outputs. Also, horror, it has better horror outputs. Cool. It does everything better. Fantastic. Want to know what I used? Here's the recipe:

Very Cool.

I'll most likely keep developing this model, since I find furry realism models for illustrious are still lacking in general quality. (But that will have to wait, I have to go back to work.)

Usage Guide

MyPreciousJimmy! - (Illustrious Realism Model)

Was disappointed with the offerings for realism in the illustrious category so I decided to merge my own. I slammed my head into this for about ten hours and this is what I got, a furry Illustrious realism model. Woo... I'll probably come back to this one to adjust the lighting, since I already merged another 'realism' model to have better lighting. But you know, time constraints, I got a lot on my plate so I wouldn't expect that one to drop anytime soon. But for now, you get this. Feel free to merge this into your illustrious mixes if you so desire. If you're going for realistic furries in Illustrious then this will probably help a little. Version changes has the usage guide for this model, but I'll post it directly below for those who can't be bothered (the usage guide posted directly below is specifically for the Illustrious model, the usage guide for the other models are posted further down in the description):

Usage Guide (for Illustrious model):

Sampler: Euler A, or DPM++ 2M if you want much more detail. I run Euler A because the detail can sometimes be too much. I have a guide further below.

CFG: 2 - 7.5, 2 - 4 is a good range. I run 3, images get very cooked past 7.5. Adjust this to also increase detail.

Steps: 17 - 50, I go with 25. You may want more or less depending on what you're going for and your hardware.

Scheduler: Automatic, or Karras. I run Karras. Feel free to experiment with this because I haven't experimented with this thoroughly, but I have ran some tests so I can offer some guidance, it follows below.

Samplers & Schedulers

Samplers Tested:

DPM Samplers (DPM++ 2M, DPM++ SDE, DPM++ 2M SDE, DPM++ 2S a, DPM++ 3M SDE, DPM2 a)
Euler Samplers (Euler a, Euler)
DDIM Samplers (DDIM, DDIM CFG++)

Schedulers Tested:

Uniform
Karras
Exponential
Polyexponential
SGM Uniform
KL Optimal
Align Your Steps
Simple
Normal
DDIM
Beta

I tested side-by-side each of the mentioned Samplers and Schedulers at what I consider optimal settings for this model when it comes to general content (CFG 3, Steps 25) and I tested for noise and detail. I did not test for artifacting or generation errors. These are my results while prompting for realistic or photorealistic images (this isn't comprehensive, this is simply my observations after limited testing, I'd post the grid tests but each file is 250 MB).

Results follow in the image below:

What is Good?

Noise and quality fall within acceptable ranges.

What is Smooth Details?

Noise is nonexistent, details are generally much smoother/flatter.

What is Noise?

Image have visible noise at the set CFG (3). You should increase CFG if you wish to generate on these Schedulers. (DDIM is good for prompting niche concepts. I felt that I should point this out, as I've been using DDIM since I first began generating).

What is Noisy/Washed Out?

Images have visible noise and is washed out. Do not use for generation (generally).

What is Poor Quality?

Finer details (eyes, vasculature, fingers, etc.) tend to generate at poor quality. Inpainting, upscaling, or refining is recommended.

What is Extreme Noise?

Noise severely degrades the image quality at these settings. Do not use.

This is in no way a comprehensive test of these schedulers and samplers. This is simply a quick guide as to what should generally be used when prompting for realistic or photorealistic imagery at what I consider to be optimal settings for the model.

CalypsoRealism - (Realism Model)

Decided to revisit DisgustinglyReal and make some adjusts using some improvements from other models I merged. Better lighting, better detail, better "realism". Wowzers. It's a "realism" model, meaning that it was designed for realistic content, but if you really, really want to try, you can force specific non-realistic styles. But again, this model was designed for "realism". There's two different file versions, CalypsoRealism and CalypsoRealism9M. What are the differences? CalypsoRealism is the base model and does "realism" slightly better, with more nonsensical details and detail density. CalypsoRealism9M is an adjustment to that.

If you're unsure of the differences or which one is the best, I posted a couple comparisons in the gallery. You can decide which version is best for you.

Though not necessary in the slightest, you can read Version Differences for more information.

DisgustinglyReal - (Realism Model)

A quick merge I made out of boredom between several custom models I merged, posted for fun.

It's a realism model, and at times disgustingly so. It has some Pony merged into it so it does respond to score tags, but it isn't primarily Pony as it is based off my other model, Echo Alpha, so E621 tags apply. If you used Echo Alpha and wanted more "realism", this is that.

This does realism, only realism.

Use however you please.

BlackDays - (Environmental Detailer)

What is this model?
This technically, but what is it? Another realism model, something made accidentally while trying to merge for a better 2D model similar to Echo Alpha V0.5.5. I've found that this model performs background scenery and lighting extremely well, while still maintaining high clarity and high detail. It's main style is realism, but it can perform other styles. This should be used as a model merging resource to inject higher background detail and better lighting into your models, as this model on its own is highly unstable. That's not say it can't generate images on its own, it's just that more complicated prompts can lead to noise/artifacting errors in A1111, and it can have some difficulty following prompts.

But for being a complete mistake, I think it turned out very well so here it is.

Use however you please.

Echo Alpha Conceptualizer

A custom SDXL model I merged and finetuned over the course of several months. Specifically designed to bolster my main model, Echo Alpha, with higher concept knowledge and prompt adherence, I have found merging it into Echo Alpha to be a long and frustrating process that after several weeks of on-and-off merging attempts I put on the backburner while I focus on real work outside of model development.

When used as a merging resource, it is advised to use it at low strengths as its effects are strong and come at the cost of image quality. From my limited testing, I have found that it understands most, if not all, of common sexual material, along with errant and some body horror concepts. If I were to make a model comparison, this model is closer to my SD 1.5 Alpha Tango model than anything else on-site. Using 'realistic', 'photorealistic', or 'real e621' tags is not recommended when prompting with this model, especially if it's with Pokémon, Digimon, or Anime, unless you like the SD 1.5 pseudo-realism look like Alpha Tango has.

Want to use these models but don't have the hardware to give it a spin?

Usage Tips:

Steps: 15-50

Sampler: whatever one you want, I would recommend DPM++ 2M, but that's just my bias. Use the sampler you find works best for the model.

CFG: 3 - 12, adjust to each model, 7.5 is fine but mileage may vary.

VAE: None is fine, adding one is no problem though.

Blah, blah, blah, you get the point. If you're using SDXL, you know what to do. These aren't natural language models and I can not attest to the models' capabilities while using natural language prompting.

Do with these models as you please, crediting unnecessary.

Feel free to post whatever images created in the gallery below.

I'm not responsible for generations produced with these models, generate responsibly.
