This weird roleplaying AI makes a great dungeon master

When AI development firm OpenAI released its GPT-2 algorithm, it warned that the tech was capable of flooding the internet with fake news and propaganda. What it didn't predict, however, is that the algorithm can also make a pretty effective dungeon master. AI Dungeon 2 (playable here) uses the full-sized GPT-2 algorithm to bring players through a text adventure-style game that it writes in real-time based on the player's prompts and commands. The game isn't perfect -- in my playing, it for some reason decided to name every single character "Dan" -- but it's fascinating all the same to let a powerful AI system take the wheel and steer the game's journey. AI Dungeon 2 is a far cry from the first version of the game, which creator and Northwestern University grad student Nathan Whitmore built around a substantially weaker version of GPT-2.
