MarioGPT

 

An IT University of Copenhagen team announced MarioGPT, an AI method for generating new Super Mario Bros. levels.   The method, described in a pre-print paper, is based on OpenAI's previous generation GPT-2 language model. To create MarioGPT, the team used a version of GPT-2 to translate user text prompts into graphical elements in game levels. For example, input could call for "many" pipes and enemies but a low elevation and small blocks for a level. An AI agent was able to complete about 90% of the 250 AI levels that were created, showing they are playable. The researchers said the aim is to enable "the open-ended generation of an increasingly diverse range of content." The instructions and code for MarioGPT are now available on GitHub.
