Silas and Marcus appears mainly on smut. This is especially problematic for me because these names remember me of two famous religious leaders of my country with whom I obviously don't wanna imagine smut with; also, I have no fetish for religious things.

Elias Thorne, Kaelen Voss, Elara Vane, Julian Penhaligon, Sora Vance, Maya Vale, Arthur... These all appear a lot. Alistair and Alaric appears more when the setting is a little medieval, and Valerius is a very common villain. Aether, Aletheia, Aegis and Unit-7 are common for non humans, and "The Architect/Curator/Moderator/Oracle" are for mysterious characters. Lysander looks like the only Greek name the AI knows. And in my native language, I see things like Beatriz Cavalcanti and Thiago Viana.

Places are always Oakhaven, Aethelgard, Ouroboros or Orizon. In rare times, I noticed Omonoia.

AI also seems to have a weird obsession with some professions, like archivist, data analyst, fixer, watchmaker, scavenger and so on.

As for the clichés it brings way too often... I think this one text is already long enough.
