The OpenAI Gym is an open source code that provides a suite of environments in which developers can work on and test their AI algorithms. These environments include a collection of test problems that can be used to work out AI algorithms. This open ‘gym’ service is also a site where developers can share and compare algorithms.

The Gym is a toolkit for developing and comparing Reinforced Learning (RL) algorithms. RL forms a part of machine learning, which focuses on decision-making and motor controls. RL research has slowed down due to lack of standardisation of environments and the need for better benchmarks, and OpenAI aims to solve both.

This is available in the Python language, and hence requires Python 2.7 installed, but will soon be expanded to other languages.

The test environment suite initially has the following environments to work out your agents:

  • Classic control and toy text: Tasks to get started from RL literature.
  • Algorithmic: To perform computations like adding and multiplying double digit numbers.
  • Atari: Play classic Atari games integrated with the Arcade Learning Environment. The list has 59 Atari games which includes Alien, Asteroids and Pac-man.
  • Board games: Play Go on 9x9 and 19x19 boards, and also two-player games with one fixed opponent. They will soon be adding new opponents and multiplayer games.
  • 2D and 3D robots: To control a robot in simulation using the MuJoCo physics engine for fast and accurate simulation.

The gym will also feature a leaderboard of most successful systems, based on how versatile the systems are. “It is not just about finding solutions which will generalise well,” a how-to guide from OpenAI explained. “Solutions which have task-specific hardcoding or otherwise don’t reveal interesting characteristics of learning algorithms are unlikely to pass review.”

In the launch blog post, OpenAI’s Greg Brockman and John Schulman had mentioned that the gym was originally built to accelerate their own research. “We hope it will be just as useful for the broader community,” the blog read.
