PAGI World

PAGI World (“pay-guy”), which stands for Psychometric Artificial General Intelligence World, is a simulation environment written in Unity 2D which allows AI and AGI researchers to test out their ideas on a wide variety of tasks, and to create their own tasks, in a real-time environment with realistic physics. PAGI World is designed to be a platform which many researchers can use to compare competing approaches to AI and AGI. With that goal in mind, there are many features which make PAGI World unique:

  • Written in Unity 2D, so that updates to Unity 2D’s physics engine will be incorporated into PAGI World as they come out
  • Many real-world elements have been created that don’t exist in other simulation environments, such as: Water/Fluid Dynamics, Sticky objects, Friction, Vision, etc.
  • Can be run on any major operating system—Windows, Mac OS, most Linux distros, iOS, Android, and more
  • Uses TCP/IP communication, so that AI agents can be written in virtually any programming language
  • Has an easy-to-use GUI Task Builder, so that researchers can create their own PAI or PAGI tasks—or just their own environments for their AI agents to play in—without writing a single line of code.
