I believe this model to be very good at photorealism although it does have some artistic capabilities as well. Here are a few tricks to using the SDXL versions of GonzaLomo to its fullest potential:

• Clip Skip is your friend. I recommend trying a prompt with both 1 and 2 values. 1 can make images that are more creative, artistic, retro or grungy whereas 2 is better at photorealism and the, um, physical attractiveness of the subject(s).

• Generate at 1024x1536 or higher using the PatchModelAddDownscale node in ComfyUI. This will create a much more detailed image that can then be upscaled further, resulting in incredible photorealistic detail. Using that node, I can do an initial generation as high as 1280x1920.

• You can play around with different sampler settings but I find that the absolute best results are with LCM/Karras, 12 steps and CFG 1.0.

• Selective usage of the Self Attention Guidance node can sometimes give amazing results. I always have it in the pipeline and usually bypassed but turn it on when I think an image has potential but just needs a little more oomph like color saturation or contrast.

• I get really interesting/creative results by generating with the V1.1 Semi-Real model and then resampling that image with the V2.0 Unity model at around 0.60 denoise. You really need to play with the denoise to find the right value that tips the image from cartoonish to photorealism but you'll be amazed at what's possible when you do. Note that V1.1 Semi-Real requires Clip Skip 2+ and will not work with 1 at all.

• And lastly, always be upscaling! More pixels equals more detail equals more photorealism.

Note: I only use ComfyUI so I apologize in advance if you're having trouble with my model in some other tool and I can't help.

Current Models

V2.0 Unity

Essentially, this is V1.1 Real with a bit of Siren Forge, Cyberrealistic and Lustify added to the mix. The base is still Gonzales and LomoXL.

I called this version Unity because I originally wanted to have separate models for photorealism and artistic styles. However, I realized that I could get both in one model and created V1.1 Artsy for that purpose but it was a failure. This is my second attempt at that combination and I think/hope it's a success.

At the very least, I don't want to degrade the photorealism capabilities and just want to add more surreal, artistic or fantastical styles as an option.

The recommended settings haven't changed since V1.1 Real:

Sampler: LCM (also dpmpp2a and ddim can provide interesting results)

Scheduler: Karras, Exponential or Beta

Steps: 8-12

CFG: 1.0-1.3

Clip Skip: 1-5

I normally keep my settings at LCM/Karras with a CFG of 1.0 but I tend to vary the clip skip between 1 and 5 because those can change the image pretty drastically. Sometimes an image at clip skip 2 will be terrible but might become amazing with clip skip 1, and vice-versa.

V1.1 Semi-Real

I'm doing a little experimenting with non-photorealistic models. This is a merge of GonzaLomo v1.1 Real and ToonComix which is a toon model that does a really good job with detailed backgrounds. The whole Comix family of models is very good so check them out.

Sampler: LCM

Scheduler: Karras, Exponential or Beta

Steps: 8-12

CFG: 1.0-1.3

Clip Skip: 2-5 (1 is not supported)

Retired Models

V1.1 Real

This is a simple 60/40 merge between two of my favorite photorealistic models - Gonzales-????-PonyV1/V2-DMD v2.0 and LomoXL (with a little bit of Lustify thrown in). Many, many thanks to the makers of those excellent models.

Gonzales is a Pony model so GonzaLomo inherits all of those capabilties. LomoXL has a very strong analog feel to it which helps give an edge to Gonzales' "pony-ness".

Sampler: LCM

Scheduler: Karras, Exponential or Beta

Steps: 8-12

CFG: 1.0-1.3

Clip Skip: 1 allows greater analog effect but lessens ???? capabilities

Clip Skip: 2-5 lessens/removes the analog effect but allows more ????

Try this workflow to get started, if you need it.

To be clear, I created this merge for my own use cases. It's certainly not better than Gonzales for most things. I'm just hoping to inject Gonzales with some of the gritty, analog feel that I was looking for in some cases. LomoXL also allows for a wider variation of faces, especially with clip skip 1.

Enjoy!

P.S. This is my first model upload so I would appreciate any constructive feedback or comments.

V1.1 Artsy alpha (Not very good imo, use V2.0 Unity instead)

This was an attempted merge between V1.1 Real and a few art-focused models. The main purpose of this model is to be able to produce artistic styles but it has the tendency to try to force photorealism when prompted clearly for an artistic style. This model has been abandoned in favor of V2.0 Unity which does a much better job of combining the photorealism of V1.1 Real with artistic styles.
