Gym is an open-source toolkit designed to facilitate the development and comparison of reinforcement learning (RL) algorithms. Originally developed by OpenAI , Gym has become a foundational resource in the reinforcement learning community, providing a standardized interface for creating and interacting with a diverse collection of RL environments. It enables researchers and developers to build, test, and benchmark RL agents efficiently.
