Just average vomit inducing over 40 year old people making you scream in mental agony. Doesn't even support dark skin people.
You can get better generations from a recently released similar Pony model.

The answer to this (I believe) depends on what interface you are using.

For some interfaces, you will need two separate files in addition to the base model checkpoint: a file with a CLIP model, and a T5-XXL file. As I understand it, these are used for interpreting and generating text, or something along those lines.

Once you've obtained these two files, you will need to place them in particular folders in your interface's install directory.,. You can search for downloads for these files, and tutoriuals for which folders to put the files in. I believe education.civitai.com also has a guide to getting started with Flux that includes links to the files you need and instructions.

Some interfaces do not seem to be able to use these separate CLIP/T5-XXL files, even though they DO support Flux models. In this case, you will need to find a model checkpoint that explicitly states that CLIP and T5-XXL are built into the checkpoint. These models will not give you that error. Baking these files into the main model checkpoint significantly increases the size of the checkpoint file, which is why most models do not bake them in, and assume that you have already obtained the necesary CLIP/T5-XXL.

Hope this was helpful to you.
