BigLove is a merge of Pony, bigAsp, Lustify and other SDXL models. The newest Photo/Insta/Lust versions of Big Love were additionally trained for more photorealism & new concepts.

Big Love Pony produces different images than both Pony & SDXL-based models. Pony tags are understood, but interpreted a bit differently. Some images lean more in the one or other direction depending on the prompt. It works with Pony loras as well as normal SDXL ones. It can turn anime/cartoon into photorealistic images in img2img. Pony3 includes a bit of Illustrious.

Big Love XL is a combination of 5 different training branches of SDXL: original SDXL, bigASP, RealVis, Anteros and Pony. With a bit of Pony in it, some Pony loras (poses, characters) work too. It outputs a more photorealistic & creative look than the Pony versions and can also do paintings & cartoon.

Big Love Photo and Insta are finetuned versions of XL. Lust is a finetuned version of Lustify merged with Photo. They were trained on thousands of images and dozens of new concepts. Why they are the most realistic and versatile. For more details and prompting Photo1 read this article.

The upcoming Big Love Ultra versions will support generating at image sizes of 1280x1870, 1360x1984 and higher. Can be easily upscaled to 6 megapixel unlike the normal low-res images. Ultra is so far still experimental, but results are already amazing. More photorealistic and detailed. A special quality that cannot be achieved by just upscaling.

Pony1/Pony2/XL1 versions were optimized for the Lightning lora while the newer versions were optimized for the DMD2 lora. Both loras speed up rendering by a factor of 3-6x and let Big Love produce more photorealistic results.

txt2img Settings:
Civitai: DPM2 a, 30-50 steps, cfg 4-5, 832x1216
Forge/ComfyUI: DPM++ SDE, Normal/SGM Unifom (Pony), Karras (XL/Photo/Insta/Lust), 20-30 steps, cfg 3-10, clip skip 2, 832x1216. For faster generation 2M SDE/3M SDE works too, but lower quality with the Pony version.

More Realistic & Faster Rendering:
Good Quality: For more contrast add the SDXL Lightning 8-step lora with DPM++ SDE, SGM Uniform, 8 steps, cfg 1.5-3 (Pony), 1-2.5 (XL/Photo/Insta/Lust), lora strength 1.0, clip skip 2, 832x1216 or 1024x1496
Best Quality: For a more natural look use the DMD2 lora with LCM Exponential, 8 steps, cfg 1 (Photo/XL4/Insta/Lust), 1-1.5 (Others), lora strength 1.0, clip skip 2, 832x1216 or 1024x1496

Upscaling:
1. txt2img with Lightning 8-step lora: Hires fix, 4x_NMKD-Superscale-SP_178000_G upscaler, 3 hires steps, 0.4 denoise, 1.5x, hires cfg 2, clip skip 2
Higher Quality & Faster Rendering:
Good Quality: img2img with Lightning 8-step lora: same prompt, DPM++ SDE, SGM Uniform, 1.25-1.5x (XL), 1.5-2x (Pony), 3 steps (ComfyUI), 6-8 steps (Pony), 4-12 steps (XL/Photo/Insta/Lust), cfg 2, lora strength 1.0, 0.3-0.5 denoise, clip skip 2
Best Quality: img2img with DMD2 lora: same prompt, LCM Exponential, 1.25-1.5x (XL/Photo), 1.5-2x (Pony), 8-12 steps (XL1/XL2) 4-8 steps (XL2.5-XL4/Photo/Insta/Lust), cfg 1, lora strength 1.0, 0.3-0.5 denoise, clip skip 2
Please note: Unlike txt2img with Hires fix, img2img offers a seed, so you get multiple image versions to choose from. img2img upscaling also produces better quality in A1111/Forge.

ComfyUI Workflow:
Download the following image and drop it into Comfy:
DMD2 txt2img & Upscale Workflow (recommended)
DMD2 img2img Workflow
Lightning Workflow
DMD2 UltraRes Workflow (experimental)
With the Lightning lora it is better to use Forge. ComfyUI is not able to do as many upscaling steps with Lightning as Forge without adding grain. But if you use the DMD2 lora, ComfyUI does just fine. The UltraRes workflow also requires the UltraRes lora for hires output.

Training a (character) lora
My advice is this: Take 10-30 high quality images (at least 50-100 for styles or poses), download OneTrainer, click the SDXL lora preset, choose Big Love as the base checkpoint, add your images as a concept, add tags on the Tools tab, and start training. But you will only get the full Big Love quality by training on real photos or extremely photorealistic images, which is usually not the case with a fictional character. It is all about image quality and not choosing boring images. Don't add posing images to a character lora, because Big Love provides the posing later for it. Focus mainly on good portraits with a few upper and full body images. Rather fewer higher quality images than a lot of average images.

Fixing Anatomy
If you want to keep the seed and repair anatomical problems in an image, activate the Extra checkbox in A1111/Forge and set Variation Strength to 0.01 to 0.1. Then generate until anatomy is fine. In Comfy there are sampler nodes that support variation seed, which do the same thing. Also possible to change steps or add commas to the prompt, but I do not recommend it. Extra/Variation Seed is more powerful and convenient as it gives you endless variations with just one click. There is always a variation which looks similar or even better with great anatomy.
You don't need negative prompts for this. They are rather ineffective. You can also change the positive prompt to suppress things. Anatomy problems are also created by the prompt if you prompt contradicting poses that the model cannot combine. Better to fix the prompt first then.

Reducing Saturation, Warm Colors and Sharpness
These loras reduces the saturation and change the color temperature without reducing image quality. The lora strength defines the effect. Negative values increase saturation or add more warmth. To make an image softer use a lower strength for the DMD2 lora, e.g. 0.95, 0.9, 0.85.

Big Love Ultra
These image sizes are supported by the Big Love Ultra versions:

1536x2240 (only certain prompts)
1432x2088 (only certain prompts)
1360x1984 (recommended)
1280x1872 (recommended)
1024x1496 (better use normal version)

You can also use the 16:9 or 2:3 versions of these image sizes as well as landscape orientation, but the above should be more reliable.
The higher the image size, the lower the probability of good results. If you get too many problems with a higher image size, switch to the next lower one. Some prompts do higher sizes fine, some do not. It is usually better to use the normal version of Big Love to create 1024x1496 images. Unless you prefer the Ultra style.
Remove fill words and unusual tags in the prompt. They can cause a quality reduction with Big Love Ultra as they were not trained. Shorter prompts should work better as it is less likely that bad or untrained tags are in it.

Strengths
Ultra: Generates at higher resolutions, More details, more photorealistic, easier to upscale to bigger sizes.
Photo/Insta/Lust: Highest photorealism & flexibility. Knows more concepts. Best image quality.
XL: Great fine details, natural looking photo-like images, lovely faces, creative poses, can also do paintings and cartoon
Pony: Probably the most photorealistic Pony model, very good anatomy knowledge, huge face variety for a Pony model, very short prompts are quite effective & photorealistic

Weaknesses
Ultra: Still exerimental, so requires more prompt tweaking and seed hunting for usable results.
Photo/Insta/Lust: Pro photo look is default (prompt amateur photo otherwise), often high contrast (low contrast prompting possible).
XL: Some prompts produce softer skin, multi-person images can have strange anatomy, limited with sexual poses and concepts
Pony: Needs rather precise prompts & takes prompt rather literally, still a bit of the Pony look depending on used prompt, it can switch between fully photorealistic and semi-realistic

SFW Output - No Tits Please
"Is there a trick so that Big Love doesn't always generate raised shirts or visible breasts?" I get this asked so often, while it is so obvious. Big Love knows what men want so it gives it to them. Negatives don't work that well for it. So you got to speak to it in the positive prompt like you were taking to a nun. "Breasts? How dare you speak such an obscene word to me." Don't mention breasts or any of these sexy parts. Instead describe clothes a lot. Don't write down your impure thoughts. God forbid! Yeah, I know, so hard. Describe her body shape, which also implies certain tits underneath the clothes.

XL Prompting Advice:
SDXL prompts & prompts from Acorn Is Boning & Lustify work with it. Pony prompts too, but they create a more photorealistic look. Natural language prompts tend to create artistic glamour images with less skin detail while normal tags do more photo-style images. Big Love XL gives individual words more attention, so you don't need to rework prompts like Big Love Pony requires sometimes.
XL1/XL2 has a tendancy towards cuteness and bright skin. If you get too much of it, remove words like cute, sweet, pale/fair skin & flash from the prompt. It also creates realistical analog photos with reduced image quality. Sometimes better to remove terms like analog or grain to increase quality. Decrease cfg to get a more natural look.
XL2.5 can sometimes get too sharp. Reduce cfg or use less steps in img2img to make images softer.

Pony Prompting Advice:
Pony prompts & prompts from bigASP & Lustify work with it. Score tags and fill words like masterpiece or perfect skin have as good as no effect usually. A negative prompt is often unnecessary unless you want to make something vanish or avoid underage, but it can also change the style of the image.
Pure booru tags and some other samplers may produce Pony style. Photographic terms or a simple prompts ensure a photo look. Sometimes it refuses to produce medium shots, portraits or close-ups unless you weigh the term heavily or remove feet, shoes, high heels, boots etc. from the prompt. wavy hair sometimes does not look so great.
If it refuses to do porn, try simplifying the prompt. If you want to do a portrait, don't describe surroundings too much. If you want to do porn, describe the action mainly and don't focus on the people or surroundings in the prompt. The largest part of the prompt should be about the main subject of the image.
If a prompt does not produce the intended image, you often only need to modify it a bit to make it work perfectly.

Using Character Loras:
Big Love Pony supports Pony characters, but they look like real humans. There were some complaints about them not working, but the problem was not the model itself so far. So here are some tips:
* Try Pony as well as SDXL character loras
* Use a lora weight up to 1.5 if it does not reduce quality
* If it is a well known character, add the name in the prompt and also give it a higher weight if necessary.
* Check your negative prompt for problems. Delete it if necessary and rewrite it from scratch.
* Render a lot of images to be able to pick those with the best resemblance.

More Photorealism:
You can highly improve the images generated with this model by using img2img, upscaling, detailing etc. The Lightning lora enhances the look and constrast despite only 8 steps. Alternatively, the DMD2 lora produces a sharp, but more natural look with less contrast. Also check out the Subtle Style loras, which nicely enhance images.

Big Love License

Big Love is licensed under CreativeML Open RAIL++M (dated July 26, 2023) with the following additional terms:

1. You may use Big Love without crediting the creator.
2. You may sell the images that it generates.
3. You may only run the official Big Love versions of the SubtleShader account on Civitai and Tensor Art. Running it on other public or shared servers (including other Civitai and Tensor Art accounts) requires a separate license or permission from the creator.
4. You may not sell this model or merges of this model.
5. You may merge low-res non-Ultra versions of Big Love and share your merges of them. You may not merge the high-res Ultra versions of Big Love, and you may not share any merges that incorporate high-res Ultra versions. Low-res versions are those trained at resolutions of 1024px and below. High-res versions include the addition "Ultra" in their name and are trained at resolutions higher than 1024px.
6. When sharing allowed merges (of non-Ultra versions) as well as finetunes, you must apply these same additional license terms.
7. Redistribution of high-res Ultra versions of Big Love is prohibited. High-res Ultra versions may only be obtained from official sources designated by the creator.
8. All use-based restrictions from Attachment A of the CreativeML Open RAIL++M license apply to this model and any derivatives.
9. Any restrictions in these additional terms may be waived only with explicit written permission from the creator.

TLDR: This is basically the same license as before (just stated more clearly), so nothing changes for non-Ultra versions. However, further restrictions were added for Ultra versions of Big Love (no merging, no redistribution). The "Share merges" condition below the license on the right hand side was only deactivated because of the Ultra versions. Merging is still allowed for the non-Ultra versions.

Many thanks to the creators of SDXL, Pony, Acorn, TamePony, bigAsp, Natvis, Anteros, Lustify and URPM for making their wonderful models available.
