For ComfyUI-users (I am sure Auto 1.1.1.1 or other UI's have a similar method), It's not about the images , but if you drag any of these in to your workflow, this one has a Primitive counter at the very beginning and the checkpoint loader has this counter as an input (you can connect this counter to any node as long as you change the parameterwidget as an input E.g. Ksampler sample name or CFG), in my example you can have an image made with every checkpoint (and change nothing else) and it will increment to the next model if you have auto queue selected, To make it even easier you can dismiss the save image (forgot to do that and now I have them double) at the very end and use the save image extended, this will put the checkpoint model in the name, This way you can test every model overnight and when you wake up you can select the model you liked best, because you can see the model that matches the image you like.
Off course you need a different lora and a different prompt to test your models, but this is not restricted to pony or SDXL, or 1.5 so you can test any model automatically without losing sleep, just set the primitive input to the first model you want, in this case pony models (I have them in different folders) so this would be pony/dream diffusion and leave it at increment to count up. Also you can change the naming in save image extended (e.g. if you want to test Alexds9 newest baby doll lora ( https://civitai.com/models/561063 ) with every pony, you choose that lora and change Droidgeisha to Babydoll, you can even save them in a different folder).
for those testing models, I think this can help you guys, If you use comfy off course, if not see if there is a similar one for Auto 1.1.1.1
