About this version:

Photo4 offers improved image quality, finer details, better anatomy, 39 new concepts (100 new concepts compared to XL4), cuter faces and slightly better prompt adherence. It was trained on 2000 new images (a total of 6000 images since XL4).

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 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 Insta1 are finetuned versions of XL. Lust1 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 .

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
