Standardized Preview Prompt for all Models

There are already a lot of models out there and it got nearly impossible to tell the difference between anime model A and anime model B for example. There should be a standardized preview prompt for all model and maybe also lora creators and those standardized prompt previews should be in the thumbnail on the website. or make it turn on and off. so people can actually see a difference. with control net and openpose it is very easy to setup a standard prompt. see attached img for example.
