Check out these pretty plain looking portraits. They are all fake. Not in the sense that they were Photoshopped, but they were entirely generated by artificial intelligence . That's right: None of these people actually exist.
NVIDIA researchers have published a new paper to customize the style of realistic faces created by a generic reverse network (GAN).
Verge points out that GAN has only existed for about four years. In 201
In less than half a decade, realism has become better at the point most people might not be able to tell that the portraits are fake when investigated further.
NVIDIA researchers can now copy "styles" of source pages to destination sites, and create mixes that have copied features, but look like brand new people: 
To make these last faces trained NVIDIA researchers AI for a full week with 8 powerful GPUs. Here's a 6-minute video about this latest progress:
Here's a collage of false faces created by AI:
This technology seems to have the potential to interfere with the photography world. It is by no means limited to generating faces – it can also create anything from fake interior real estate images …
… to false car pictures …
… to false ] cat photos …
A march against artificially generated "images" has already taken place for years: back in 2014, 75% of IKEA's catalogs were already date generated.
It may be a scary thought for stock photographers, but in the future it may be so easy to make "photographs" out of thin air like entering a description in an AI-driven desktop image.
