OpenAI Gym
OpenAI Gym (also known as Gymnasium) is a toolkit that helps developers test and create artificial intelligence programs, particularly in the field of reinforcement learning. Think of it like a training ground or practice arena where AI programs can learn through trial and error. Just as athletes use gyms to practice and improve, AI developers use OpenAI Gym to train their AI models in simulated environments. It's particularly useful for creating AI that needs to learn how to make decisions or perform actions, like game-playing AI or robotic control systems.
