AI Dungeon Universes

Universes Are Vibes

A universe doesn’t have any concrete world info, like locations or characters. Instead, a universe is more like a vibe. It influences the literary style of the AI, as well as the types of events or characters that might be encountered. Right now, we only have two universes, normal and horror (aka. H.P. Lovecraft), but we intend to add more. You’ll be able to set the universe per-adventure, at the top of the world info page for that adventure.

The universe setting will be available on the world info page, at the top.

Making AI Dungeon (And Universes)

In the beginning, there was GPT-3, which was basically really good auto-complete. It could complete all sorts of things: reviews, news articles, poetry, etc. However, Nick, mysterious and wise, didn’t want GPT-3 to complete poetry, he wanted it to complete adventures, sort of like a dungeon master.

The Cthulhu Model

AI Dungeon is a copy of GPT-3 trained on Choose Your Story data. The Cthulhu model is similarly a copy trained on H.P. Lovecraft stories.

One Model To Rule Them All

Why not keep going? Money, in short. Each copy of GPT-3 we run costs a lot of money per month. Trust me when I say even 5–10 universes would be totally unsustainable.

Examples of CTRL tags. Each text document they have is tagged (in red) with where it came from (books, horror stories, yelp reviews, reddit relationship advice, etc.). The prompt is in blue. Each tag makes the model auto-complete the document as if it came from that source.
Example of adding tags to the tops of stories. We’re experimenting with the right format for the tags, so this isn’t necessarily what you’ll see in game.
When universes are enabled, we’ll append the appropriate tag to the top of the story (but hidden from story history, like memory). This puts AI Dungeon in the appropriate “mode.”

Testing Universes

Generally, we have a three step process for rolling out a new version of AI Dungeon.
