It would be refreshing to see a version of this where the avatars actually look like plausible users and not models/dolls/uncanny robots. Backgrounds, less attractive faces, and different poses would help. Most of the time avatars come from candid snapshots.
Perhaps something powered by thispersondoesnotexist.com would better for that. That site returns completely AI-generated faces that seem much more realistic and candid.
thispersondoesnotexist.com is great, but doesn't provide metadata, and one of the primary goals was to be able to have consistent names with images, so boys don't get girls names. Also multiple sizes and fixed ids where needed.
The lighting, esp color temperature, backgrounds, angles and zoom amount all very uniform and Center, it looks like a game avatar. If you look at fb profiles you will know
Missed this comment. Yes, there was a service where you can either use the API or link to a random avatar of real people. I have forgotten the name but I can look around and it should be there.
I would download/test an App and I would be looking at my Avatar/Picture with someone else's name.
