Adventurer! Will you attack with easy nobleness, taking reputation points from you everytime you hit back, ten times? Or will you tell the priest to finish what's been going on with your family, thrice combined this time with Gramm Corps' arcane branding? THE CHOICE IS YOURS in Nick Walton's AI Dungeon!

AI Dungeon is an AI generated text adventure that uses deep learning to create each adventure. It uses OpenAI's new GPT-2 model, which has 117 million parameters, to generate each story block and possible action.

For each choice that is made, the initial prompt, the last story block, and the last action are fed into the neural network. The resulting story and action options are then output by the model.
