Gym is a playground for AI agent to learn to perform their task with flexible classes and customization to improve accuracy more and more. I compare my reinforcement learning algorithms like DDPG, DQN and PPO, while training Gym enhance my model abilities and train my model on different algorithms and compare batter preformed algorithms. Gym is open sourcre and it have classes and modules and custom environments for specific need and to simulate specialized task. overall Gym is feature rich and user friendly toolkit. Review collected by and hosted on G2.com. What do you dislike about Gymnasium? Gym hasn't distributed training support for complex environments or larger model. also it hasn't multi agent training environment this too much limitations like gym hasn't built in transfer learning support Review collected by and hosted on G2.com.

One of the best advancements is its work with multiple algorithms written in any framework. Gym provides me the ability to test my algorithms on high levels of complexity and many types of tasks. Gym API provides an interface of environments to compare the performance of different RL algorithms. Review collected by and hosted on G2.com. What do you dislike about Gymnasium? One of the biggest disadvantages I found Gym does not support multi-agent environments it has single-agent environments as multiple agents work in a shared environment which is very good for reinforcement learning. version capability problems packages can issues during installation and usage. update problem Gym library remains up to date with the latest advancements and latest environments with time Review collected by and hosted on G2.com.
