Are there any comprehensive collections of AI-generated portraits of human faces (photorealistic, male/female, old/young, different skin colors, various facial expressions) that are free to use?
Analogous to the free Icon Sets (such as fontawesome.com), but more a "faces set". Free to use just as with photos from, say, unsplash.com.
I sometimes have to build mockups of web pages, for demo or development purposes. Often these pages have a portrait photo inside, or an avatar picture.
I wonder if there are collections of AI-generated faces such as this spectacular collection of superhero characters - but these images look unnatural and are certainly not free to use.
