Steam's AI Generated Content Disclosure states:
The developers describe how their game uses AI Generated Content like this:
-Some base textures have been AI generated during the development
-Some of the imagery and speech audio in the in-game TV programs are AI generated
-Some in-game radio music is AI generated
And a post by the developer specifically stating where AI is used.
Here is a specific rundown of the AI used in the game:
-One TV program that has two episodes, around 5min in length each (images and speech is AI, but written, edited and music composed by humans)
-One TV commercial 10sec in lenght
-Paintings on the house walls (same as in MSC)
-Food pictures/textures, around 12 separate pieces
-"Carbon fiber finish" texture, but this is definitely not important so it can be removed :D
-And then maybe half (in minutes) of the music on the radio, generated by AI and lyrics written by humans except for one instrumental song. These can be removed (apart from one song that is part of the game feature), but there is no replacement. Lets just say that without them, the radio experience is... rather interesting.
