They took his JERB | AI Creates Rap Lyrics, Makes Its Own Kanye Song

[Eldon]

A 17-year-old from West Virginia has used an archive of Kanye West lyrics to train a neural network to write rhymes on its own. The results are braggadocious, intermittently obscene, frequently incomprehensible, and laced with nonsensical name-drops.
In other words, they're pretty good rap lyrics.
